IMGUI_APIvoidEndFrame();// ends the Dear ImGui frame. automatically called by Render(). If you don't need to render data (skipping rendering) you may call EndFrame() without Render()... but you'll have wasted CPU already! If you don't need to render, better to not create any windows and not call NewFrame() at all!

IMGUI_APIboolIsWindowHovered(ImGuiHoveredFlagsflags=0);// is current window hovered (and typically: not blocked by a popup/modal)? see flags for options. NB: If you are trying to check whether your mouse should be dispatched to imgui or to your app, you should use the 'io.WantCaptureMouse' boolean for that! Please read the FAQ!

IMGUI_APIvoidSetCursorPos(constImVec2&local_pos);// are using the main, absolute coordinate system.
IMGUI_APIImVec2GetCursorScreenPos();// cursor position in absolute coordinates (useful to work with ImDrawList API). generally top-left == GetMainViewport()->Pos == (0,0) in single viewport mode, and bottom-right == GetMainViewport()->Pos+Size == io.DisplaySize in single-viewport mode.
IMGUI_APIvoidSetCursorScreenPos(constImVec2&pos);// cursor position in absolute coordinates
IMGUI_APIvoidAlignTextToFramePadding();// vertically align upcoming text baseline to FramePadding.y so that it will align properly to regularly framed items (call if you have text on a line before a framed item)
IMGUI_APIfloatGetTextLineHeight();// ~ FontSize
IMGUI_APIfloatGetTextLineHeightWithSpacing();// ~ FontSize + style.ItemSpacing.y (distance in pixels between 2 consecutive lines of text)
IMGUI_APIImGuiIDGetID(constchar*str_id);// calculate unique ID (hash of whole ID stack + given parameter). e.g. if you want to query into ImGuiStorage yourself
IMGUI_APIvoidTextUnformatted(constchar*text,constchar*text_end=NULL);// raw text without formatting. Roughly equivalent to Text("%s", text) but: A) doesn't require null terminated string if 'text_end' is specified, B) it's faster, no memory copy is done, no buffer size limits, recommended for long chunks of text.
IMGUI_APIvoidText(constchar*fmt,...)IM_FMTARGS(1);// formatted text
IMGUI_APIvoidTextWrapped(constchar*fmt,...)IM_FMTARGS(1);// shortcut for PushTextWrapPos(0.0f); Text(fmt, ...); PopTextWrapPos();. Note that this won't work on an auto-resizing window if there's no other widgets to extend the window width, yoy may need to set a size using SetNextWindowSize().

IMGUI_APIvoidBullet();// draw a small circle + keep the cursor on the same line. advance cursor x position by GetTreeNodeToLabelSpacing(), same distance that TreeNode() uses
// - The old Combo() api are helpers over BeginCombo()/EndCombo() which are kept available for convenience purpose. This is analogous to how ListBox are created.
IMGUI_APIboolCombo(constchar*label,int*current_item,constchar*items_separated_by_zeros,intpopup_max_height_in_items=-1);// Separate items with \0 within a string, end item-list with \0\0. e.g. "One\0Two\0Three\0"
// - CTRL+Click on any drag box to turn them into an input box. Manually input values aren't clamped and can go off-bounds.
// - For all the Float2/Float3/Float4/Int2/Int3/Int4 versions of every functions, note that a 'float v[X]' function argument is the same as 'float* v', the array syntax is just a way to document the number of elements that are expected to be accessible. You can pass address of your first element out of a contiguous set, e.g. &myvector.x
// - Adjust format string to decorate the value with a prefix, a suffix, or adapt the editing and display precision e.g. "%.3f" -> 1.234; "%5.2f secs" -> 01.23 secs; "Biscuit: %.0f" -> Biscuit: 1; etc.
// - Speed are per-pixel of mouse movement (v_speed=0.2f: mouse needs to move by 5 pixels to increase value by 1). For gamepad/keyboard navigation, minimum speed is Max(v_speed, minimum_step_at_given_precision).
// - We use the same sets of flags for DragXXX() and SliderXXX() functions as the features are the same and it makes it easier to swap them.
// - Legacy: Pre-1.78 there are DragXXX() function signatures that takes a final `float power=1.0f' argument instead of the `ImGuiSliderFlags flags=0' argument.

IMGUI_APIvoidSetColorEditOptions(ImGuiColorEditFlagsflags);// initialize current options (generally on application startup) if you want to select a default format, picker type, etc. User will be able to change many settings, unless you pass the _NoOptions flag to your calls.
// - TreeNode functions return true when the node is open, in which case you need to also call TreePop() when you are finished displaying the tree node contents.
IMGUI_APIboolTreeNode(constchar*str_id,constchar*fmt,...)IM_FMTARGS(2);// helper variation to easily decorelate the id from the displayed string. Read the FAQ about why and how to use ID. to align arbitrary text at the same level as a TreeNode() you can use Bullet().
IMGUI_APIvoidTreePush(constchar*str_id);// ~ Indent()+PushId(). Already called by TreeNode() when returning true, but you can call TreePush/TreePop yourself if desired.
IMGUI_APIfloatGetTreeNodeToLabelSpacing();// horizontal distance preceding label when using TreeNode*() or Bullet() == (g.FontSize + style.FramePadding.x*2) for a regular unframed TreeNode
IMGUI_APIboolCollapsingHeader(constchar*label,ImGuiTreeNodeFlagsflags=0);// if returning 'true' the header is open. doesn't indent nor push on ID stack. user doesn't have to call TreePop().
IMGUI_APIboolCollapsingHeader(constchar*label,bool*p_visible,ImGuiTreeNodeFlagsflags=0);// when 'p_visible != NULL': if '*p_visible==true' display an additional small close button on upper right of the header which will set the bool to false when clicked, if '*p_visible==false' don't display the header.
// - Neighbors selectable extend their highlight bounds in order to leave no gap between them. This is so a series of selected Selectable appear contiguous.
IMGUI_APIboolSelectable(constchar*label,boolselected=false,ImGuiSelectableFlagsflags=0,constImVec2&size=ImVec2(0,0));// "bool selected" carry the selection state (read-only). Selectable() is clicked is returns true so you can modify your selection state. size.x==0.0: use remaining width, size.x>0.0: specify width. size.y==0.0: use label height, size.y>0.0: specify height
IMGUI_APIboolSelectable(constchar*label,bool*p_selected,ImGuiSelectableFlagsflags=0,constImVec2&size=ImVec2(0,0));// "bool* p_selected" point to the selection state (read-write), as a convenient helper.
// - This is essentially a thin wrapper to using BeginChild/EndChild with some stylistic changes.
// - The BeginListBox()/EndListBox() api allows you to manage your contents and selection state however you want it, by creating e.g. Selectable() or any items.
// - The simplified/old ListBox() api are helpers over BeginListBox()/EndListBox() which are kept available for convenience purpose. This is analoguous to how Combos are created.
// - Choose frame width: size.x > 0.0f: custom / size.x < 0.0f or -FLT_MIN: right-align / size.x = 0.0f (default): use current ItemWidth
// - Choose frame height: size.y > 0.0f: custom / size.y < 0.0f or -FLT_MIN: bottom-align / size.y = 0.0f (default): arbitrary default height which can fit ~7 items
IMGUI_APIboolBeginListBox(constchar*label,constImVec2&size=ImVec2(0,0));// open a framed scrolling region
IMGUI_APIvoidEndListBox();// only call EndListBox() if BeginListBox() returned true!

IMGUI_APIboolMenuItem(constchar*label,constchar*shortcut=NULL,boolselected=false,boolenabled=true);// return true when activated. shortcuts are displayed for convenience but not processed by ImGui at the moment
IMGUI_APIvoidSetTooltip(constchar*fmt,...)IM_FMTARGS(1);// set a text-only tooltip, typically use with ImGui::IsItemHovered(). override any previous call to SetTooltip().
// - They block normal mouse hovering detection (and therefore most mouse interactions) behind them.
// - If not modal: they can be closed by clicking anywhere outside them, or by pressing ESCAPE.
// - Their visibility state (~bool) is held internally instead of being held by the programmer as we are used to with regular Begin*() calls.
// - The 3 properties above are related: we need to retain popup visibility state in the library because popups may be closed as any time.
// - You can bypass the hovering restriction by using ImGuiHoveredFlags_AllowWhenBlockedByPopup when calling IsItemHovered() or IsWindowHovered().
// - IMPORTANT: Popup identifiers are relative to the current ID stack, so OpenPopup and BeginPopup generally needs to be at the same level of the stack.
// This is sometimes leading to confusing mistakes. May rework this in the future.
// Popups: begin/end functions
// - BeginPopup(): query popup state, if open start appending into the window. Call EndPopup() afterwards. ImGuiWindowFlags are forwarded to the window.
// - BeginPopupModal(): block every interactions behind the window, cannot be closed by user, add a dimming background, has a title bar.
IMGUI_APIboolBeginPopup(constchar*str_id,ImGuiWindowFlagsflags=0);// return true if the popup is open, and you can start outputting to it.
IMGUI_APIboolBeginPopupModal(constchar*name,bool*p_open=NULL,ImGuiWindowFlagsflags=0);// return true if the modal is open, and you can start outputting to it.
IMGUI_APIvoidEndPopup();// only call EndPopup() if BeginPopupXXX() returns true!
// - Use ImGuiPopupFlags_NoOpenOverExistingPopup to avoid opening a popup if there's already one at the same level. This is equivalent to e.g. testing for !IsAnyPopupOpen() prior to OpenPopup().
IMGUI_APIvoidOpenPopup(constchar*str_id,ImGuiPopupFlagspopup_flags=0);// call to mark popup as open (don't call every frame!).
IMGUI_APIvoidOpenPopupOnItemClick(constchar*str_id=NULL,ImGuiPopupFlagspopup_flags=1);// helper to open popup when clicked on last item. return true when just opened. (note: actually triggers on the mouse _released_ event to be consistent with popup behaviors)
// - IMPORTANT: Notice that BeginPopupContextXXX takes ImGuiPopupFlags just like OpenPopup() and unlike BeginPopup(). For full consistency, we may add ImGuiWindowFlags to the BeginPopupContextXXX functions in the future.
// - IMPORTANT: we exceptionally default their flags to 1 (== ImGuiPopupFlags_MouseButtonRight) for backward compatibility with older API taking 'int mouse_button = 1' parameter, so if you add other flags remember to re-add the ImGuiPopupFlags_MouseButtonRight.
IMGUI_APIboolBeginPopupContextItem(constchar*str_id=NULL,ImGuiPopupFlagspopup_flags=1);// open+begin popup when clicked on last item. if you can pass a NULL str_id only if the previous item had an id. If you want to use that on a non-interactive item such as Text() you need to pass in an explicit ID here. read comments in .cpp!
IMGUI_APIboolBeginPopupContextWindow(constchar*str_id=NULL,ImGuiPopupFlagspopup_flags=1);// open+begin popup when clicked on current window.
IMGUI_APIboolBeginPopupContextVoid(constchar*str_id=NULL,ImGuiPopupFlagspopup_flags=1);// open+begin popup when clicked in void (where there are no windows).

IMGUI_APIboolTableSetColumnIndex(intcolumn_n);// append into the specified column. Return true when column is visible.
IMGUI_APIconstchar*TableGetColumnName(intcolumn_n=-1);// return "" if column didn't have a name declared by TableSetupColumn(). Pass -1 to use current column.
IMGUI_APIImGuiTableColumnFlagsTableGetColumnFlags(intcolumn_n=-1);// return column flags so you can query their Enabled/Visible/Sorted/Hovered status flags. Pass -1 to use current column.
IMGUI_APIvoidTableSetBgColor(ImGuiTableBgTargettarget,ImU32color,intcolumn_n=-1);// change the color of a cell, row, or column. See ImGuiTableBgTarget_ flags for details.
IMGUI_APIvoidNextColumn();// next column, defaults to current row or next row if the current row is finished
IMGUI_APIintGetColumnIndex();// get current column index
IMGUI_APIfloatGetColumnWidth(intcolumn_index=-1);// get column width (in pixels). pass -1 to use current column
IMGUI_APIvoidSetColumnWidth(intcolumn_index,floatwidth);// set column width (in pixels). pass -1 to use current column
IMGUI_APIfloatGetColumnOffset(intcolumn_index=-1);// get position of column line (in pixels, from the left side of the contents region). pass -1 to use current column, otherwise 0..GetColumnsCount() inclusive. column 0 is typically 0.0f

IMGUI_APIvoidSetTabItemClosed(constchar*tab_or_docked_window_label);// notify TabBar or Docking system of a closed tab/window ahead (useful to reduce visual flicker on reorderable tab bars). For tab-bar: call after BeginTabBar() and before Tab submissions. Otherwise call with a window name.
// - If you stop calling BeginDragDropSource() the payload is preserved however it won't have a preview tooltip (we currently display a fallback "..." tooltip as replacement)
IMGUI_APIboolBeginDragDropSource(ImGuiDragDropFlagsflags=0);// call when the current item is active. If this return true, you can call SetDragDropPayload() + EndDragDropSource()
IMGUI_APIboolSetDragDropPayload(constchar*type,constvoid*data,size_tsz,ImGuiCondcond=0);// type is a user defined string of maximum 32 characters. Strings starting with '_' are reserved for dear imgui internal types. Data is copied and held by imgui.
IMGUI_APIboolBeginDragDropTarget();// call after submitting an item that may receive a payload. If this returns true, you can call AcceptDragDropPayload() + EndDragDropTarget()
IMGUI_APIconstImGuiPayload*AcceptDragDropPayload(constchar*type,ImGuiDragDropFlagsflags=0);// accept contents of a given type. If ImGuiDragDropFlags_AcceptBeforeDelivery is set you can peek into the payload before the mouse button is released.
IMGUI_APIvoidEndDragDropTarget();// only call EndDragDropTarget() if BeginDragDropTarget() returns true!
IMGUI_APIconstImGuiPayload*GetDragDropPayload();// peek directly into the current payload from anywhere. may return NULL. use ImGuiPayload::IsDataType() to test for the payload type.

IMGUI_APIboolIsItemActive();// is the last item active? (e.g. button being held, text field being edited. This will continuously return true while holding mouse button on an item. Items that don't interact will always return false)
IMGUI_APIboolIsItemClicked(ImGuiMouseButtonmouse_button=0);// is the last item clicked? (e.g. button/node just clicked on) == IsMouseClicked(mouse_button) && IsItemHovered()
IMGUI_APIboolIsItemEdited();// did the last item modify its underlying value this frame? or was pressed? This is generally the same as the "bool" return value of many widgets.
IMGUI_APIboolIsItemDeactivated();// was the last item just made inactive (item was previously active). Useful for Undo/Redo patterns with widgets that requires continuous editing.
IMGUI_APIboolIsItemDeactivatedAfterEdit();// was the last item just made inactive and made a value change when it was active? (e.g. Slider/Drag moved). Useful for Undo/Redo patterns with widgets that requires continuous editing. Note that you may get false positives (some widgets such as Combo()/ListBox()/Selectable() will return true even when clicking an already selected item).
IMGUI_APIvoidSetItemAllowOverlap();// allow last item to be overlapped by a subsequent item. sometimes useful with invisible buttons, selectables, etc. to catch unused area.
IMGUI_APIboolIsRectVisible(constImVec2&size);// test if rectangle (of given size, starting from cursor position) is visible / not clipped.
IMGUI_APIboolIsRectVisible(constImVec2&rect_min,constImVec2&rect_max);// test if rectangle (in screen space) is visible / not clipped. to perform coarse clipping on user's side.

This is locked and return 0.0f until the mouse moves past a distance threshold at least once (if lock_threshold < -1.0f, uses io.MouseDraggingThreshold)
IMGUI_APIImGuiMouseCursorGetMouseCursor();// get desired cursor type, reset in ImGui::NewFrame(), this is updated during the frame. valid before Render(). If you use software rendering by setting io.MouseDrawCursor ImGui will render those for you
IMGUI_APIvoidCaptureMouseFromApp(boolwant_capture_mouse_value=true);// attention: misleading name! manually override io.WantCaptureMouse flag next frame (said flag is entirely left for your application to handle). This is equivalent to setting "io.WantCaptureMouse = want_capture_mouse_value;" after the next NewFrame() call.

Notify when the string wants to be resized (for string types which hold a cache of their Size). You will be provided a new BufSize in the callback and NEED to honor it. (see misc/cpp/imgui_stdlib.h for an example of using this)

ImGuiConfigFlags_NavEnableKeyboard=1<<0,// Master keyboard navigation enable flag. NewFrame() will automatically fill io.NavInputs[] based on io.KeysDown[].
ImGuiConfigFlags_NavEnableGamepad=1<<1,// Master gamepad navigation enable flag. This is mostly to instruct your imgui backend to fill io.NavInputs[]. Backend also needs to set ImGuiBackendFlags_HasGamepad.
ImGuiConfigFlags_NavEnableSetMousePos=1<<2,// Instruct navigation to move the mouse cursor. May be useful on TV/console systems where moving a virtual mouse is awkward.

ImGuiConfigFlags_NoMouseCursorChange=1<<5,// Instruct backend to not alter mouse cursor shape and visibility. Use if the backend cursor changes are interfering with yours and you don't want to use SetMouseCursor() to change mouse cursor.

ImGuiBackendFlags_RendererHasVtxOffset=1<<3// Backend Renderer supports ImDrawCmd::VtxOffset. This enables output of large meshes (64K+ vertices) while still using 16-bit indices.
// During initialization or between frames, feel free to just poke into ImGuiStyle directly.
// - Tip: Use your programming IDE navigation facilities on the names in the _second column_ below to find the actual members and their description.
// In Visual Studio IDE: CTRL+comma ("Edit.NavigateTo") can follow symbols in comments, whereas CTRL+F12 ("Edit.GoToImplementation") cannot.
// With Visual Assist installed: ALT+G ("VAssistX.GoToImplementation") can also follow symbols in comments.
// - When changing this enum, you need to update the associated internal table GStyleVarInfo[] accordingly. This is where we link enum values to members offset/type.

ImGuiSliderFlags_InvalidMask_=0x7000000F// [Internal] We treat using those bits as being potentially a 'float power' argument from the previous API that has got miscast to this enum, and will trigger an assert if needed.
// Important: Treat as a regular enum! Do NOT combine multiple values using binary operators! All the functions above treat 0 as a shortcut to ImGuiCond_Always.
// Defining a custom placement new() with a custom parameter allows us to bypass including <new> which on some platforms complains when user has disabled exceptions.
// Lightweight std::vector<>-like class to avoid dragging dependencies (also, some implementations of STL with debug enabled are absurdly slow, we bypass it so our code runs fast in debug).
// - You generally do NOT need to care or use this ever. But we need to make it available in imgui.h because some of our public structures are relying on it.
// - We use std-like naming convention here, which is a little unusual for this codebase.
// - Important: clear() frees memory, resize(0) keep the allocated buffer. We use resize(0) a lot to intentionally recycle allocated buffers across frames and amortize our costs.
// - Important: our implementation does NOT call C++ constructors/destructors, we treat everything as raw data! This is intentional but be extra mindful of that,
// Do NOT use this class as a std::vector replacement in your own code! Many of the structures used by dear imgui can be safely initialized by a zero-memset.
// NB: It is illegal to call push_back/push_front/insert with a reference pointing inside the ImVector data itself! e.g. v.push_back(v[10]) is forbidden.

floatPopupRounding;// Radius of popup window corners rounding. (Note that tooltip windows use WindowRounding)
floatPopupBorderSize;// Thickness of border around popup/tooltip windows. Generally set to 0.0f or 1.0f. (Other values are not well tested and more CPU/GPU costly).
ImVec2TouchExtraPadding;// Expand reactive bounding box for touch-based system where touch position is not accurate enough. Unfortunately we don't sort widgets so priority on overlap will always be given to the first widget. So don't grow this too much!
floatTabMinWidthForCloseButton;// Minimum width for close button to appears on an unselected tab when hovered. Set to 0.0f to always show when hovering, set to FLT_MAX to never show close button unless selected.
ImVec2SelectableTextAlign;// Alignment of selectable text. Defaults to (0.0f, 0.0f) (top-left aligned). It's generally important to keep this left-aligned if you want to lay multiple items on a same line.

boolConfigWindowsResizeFromEdges;// = true // Enable resizing of windows from their edges and from the lower-left corner. This requires (io.BackendFlags & ImGuiBackendFlags_HasMouseCursors) because it needs mouse cursor feedback. (This used to be a per-window ImGuiWindowFlags_ResizeFromAnySide flag)

boolMouseDown[5];// Mouse buttons: 0=left, 1=right, 2=middle + extras (ImGuiMouseButton_COUNT == 5). Dear ImGui mostly uses left and right buttons. Others buttons allows us to track if the mouse is being used by your application + available to user as a convenience via IsMouse** API.
boolKeysDown[512];// Keyboard keys that are pressed (ideally left in the "native" order your engine has access to keyboard keys, so you can use your own defines/enums for keys).
floatNavInputs[ImGuiNavInput_COUNT];// Gamepad inputs. Cleared back to zero by EndFrame(). Keyboard keys will be auto-mapped and be written here by NewFrame().
boolWantCaptureMouse;// Set when Dear ImGui will use mouse inputs, in this case do not dispatch them to your main game/application (either way, always pass on mouse inputs to imgui). (e.g. unclicked mouse is hovering over an imgui window, widget is active, mouse was clicked over an imgui window, etc.).
boolWantCaptureKeyboard;// Set when Dear ImGui will use keyboard inputs, in this case do not dispatch them to your main game/application (either way, always pass keyboard inputs to imgui). (e.g. InputText active, or an imgui window is focused and navigation is enabled, etc.).
boolWantTextInput;// Mobile/console: when set, you may display an on-screen keyboard. This is set by Dear ImGui when it wants textual keyboard input to happen (e.g. when a InputText widget is active).
boolWantSetMousePos;// MousePos has been altered, backend should reposition mouse on next frame. Rarely used! Set only when ImGuiConfigFlags_NavEnableSetMousePos flag is enabled.
boolWantSaveIniSettings;// When manual .ini load/save is active (io.IniFilename == NULL), this will be set to notify your application that you can call SaveIniSettingsToMemory() and save yourself. Important: clear io.WantSaveIniSettings yourself after saving!
boolNavActive;// Keyboard/Gamepad navigation is currently allowed (will handle ImGuiKey_NavXXX events) = a window is focused and it doesn't use the ImGuiWindowFlags_NoNavInputs flag.
boolNavVisible;// Keyboard/Gamepad navigation is visible and allowed (will handle ImGuiKey_NavXXX events).

ImVec2MouseDelta;// Mouse delta. Note that this is zero if either current or previous position are invalid (-FLT_MAX,-FLT_MAX), so a disappearing/reappearing mouse won't have a huge delta.
boolMouseDownOwned[5];// Track if button was clicked inside a dear imgui window. We don't request mouse capture from the application if click started outside ImGui bounds.
// - ImGuiInputTextFlags_CallbackEdit: Callback on buffer edit (note that InputText() already returns true on edit, the callback is useful mainly to manipulate the underlying buffer while focus is active)
// - ImGuiInputTextFlags_CallbackAlways: Callback on each iteration
// - ImGuiInputTextFlags_CallbackCompletion: Callback on pressing TAB
// - ImGuiInputTextFlags_CallbackHistory: Callback on pressing Up/Down arrows
// - ImGuiInputTextFlags_CallbackCharFilter: Callback on character inputs to replace or discard them. Modify 'EventChar' to replace or discard, or return 1 in callback to discard.
ImGuiInputTextFlagsEventFlag;// One ImGuiInputTextFlags_Callback* // Read-only
ImGuiInputTextFlagsFlags;// What user passed to InputText() // Read-only
void*UserData;// What user passed to InputText() // Read-only
// Arguments for the different callback events
// - To modify the text buffer in a callback, prefer using the InsertChars() / DeleteChars() function. InsertChars() will take care of calling the resize callback if necessary.
// - If you know your edits are not going to resize the underlying buffer allocation, you may modify the contents of 'Buf[]' directly. You need to update 'BufTextLen' accordingly (0 <= BufTextLen < BufSize) and set 'BufDirty'' to true so InputText can update its internal state.
ImWcharEventChar;// Character input // Read-write // [CharFilter] Replace character with another one, or set to zero to drop. return 1 is equivalent to setting EventChar=0;
char*Buf;// Text buffer // Read-write // [Resize] Can replace pointer / [Completion,History,Always] Only write to pointed data, don't replace the actual pointer!
intBufTextLen;// Text length (in bytes) // Read-write // [Resize,Completion,History,Always] Exclude zero-terminator storage. In C land: == strlen(some_text), in C++ land: string.length()
intBufSize;// Buffer size (in bytes) = capacity+1 // Read-only // [Resize,Completion,History,Always] Include zero-terminator storage. In C land == ARRAYSIZE(my_char_array), in C++ land: string.capacity()+1
boolBufDirty;// Set if you modify Buf/BufTextLen! // Write // [Completion,History,Always]
ImS16SortOrder;// Index within parent ImGuiTableSortSpecs (always stored in order starting from 0, tables sorted on a single criteria will always have a 0 here)
ImGuiSortDirectionSortDirection:8;// ImGuiSortDirection_Ascending or ImGuiSortDirection_Descending (you can use this or SortSign, whichever is more convenient for your sort function)
intSpecsCount;// Sort spec count. Most often 1. May be > 1 when ImGuiTableFlags_SortMulti is enabled. May be == 0 when ImGuiTableFlags_SortTristate is enabled.

// Helper: Execute a block of code at maximum once a frame. Convenient if you want to quickly create an UI within deep-nested code that runs multiple times every frame.
// We use it to e.g. store collapse state for a tree (Int 0/1)
// This is optimized for efficient lookup (dichotomy into a contiguous buffer) and rare insertion (typically tied to user interactions aka max once a frame)
// - References are only valid until a new value is added to the storage. Calling a Set***() function or a Get***Ref() function invalidates the pointer.
// - A typical use case where this is convenient for quick hacking (e.g. add storage during a live Edit&Continue session if you can't modify existing struct)
// (Dear ImGui already clip items based on their bounds but it needs to measure text size to do so, whereas manual coarse clipping before submission makes this cost and your own data fetching/submission cost almost null)

// while (clipper.Step())
// for (int i = clipper.DisplayStart; i < clipper.DisplayEnd; i++)

// Generally what happens is:
// - Clipper lets you process the first element (DisplayStart = 0, DisplayEnd = 1) regardless of it being visible or not.
// - User code submit one element.
// - Clipper can measure the height of the first element
// - Clipper calculate the actual range of elements to display based on the current clipping rectangle, position the cursor before the first visible element.
// items_count: Use INT_MAX if you don't know how many items you have (in which case the cursor won't be advanced in the final step)
// items_height: Use -1.0f to be calculated automatically on first step. Otherwise pass in the distance between your items, typically GetTextLineHeightWithSpacing() or GetFrameHeightWithSpacing().

// **Avoid storing ImColor! Store either u32 of ImVec4. This is not a full-featured color class. MAY OBSOLETE.
// **None of the ImGui API are using ImColor directly but you can use it as a convenience to pass colors in either ImU32 or ImVec4 formats. Explicitly cast to ImU32 or ImVec4 if needed.
// The expected behavior from your rendering function is 'if (cmd.UserCallback != NULL) { cmd.UserCallback(parent_list, cmd); } else { RenderTriangles() }'
// If you want to override the signature of ImDrawCallback, you can simply use e.g. '#define ImDrawCallback MyDrawCallback' (in imconfig.h) + update rendering backend accordingly.
// This is useful for example if you submitted callbacks which you know have altered the render state and you want it to be restored.
// It is not done by default because they are many perfectly useful way of altering render state for imgui contents (e.g. changing shader/blending settings before an Image call).

unsignedintElemCount;// 4 // Number of indices (multiple of 3) to be rendered as triangles. Vertices are stored in the callee ImDrawList's vtx_buffer[] array, indices in idx_buffer[].
// To allow large meshes with 16-bit indices: set 'io.BackendFlags |= ImGuiBackendFlags_RendererHasVtxOffset' and handle ImDrawCmd::VtxOffset in the renderer backend (recommended).
// You can override the vertex format layout by defining IMGUI_OVERRIDE_DRAWVERT_STRUCT_LAYOUT in imconfig.h
// The code expect ImVec2 pos (8 bytes), ImVec2 uv (8 bytes), ImU32 col (4 bytes), but you can re-order them or add other fields as needed to simplify integration in your engine.
// The type has to be described within the macro (you can either declare the struct or use a typedef). This is because ImVec2/ImU32 are likely not declared a the time you'd want to set your type up.
// NOTE: IMGUI DOESN'T CLEAR THE STRUCTURE AND DOESN'T CALL A CONSTRUCTOR SO ANY CUSTOM FIELD WILL BE UNINITIALIZED. IF YOU ADD EXTRA FIELDS (SUCH AS A 'Z' COORDINATES) YOU WILL NEED TO CLEAR THEM DURING RENDER OR TO IGNORE THEM.

// You are totally free to apply whatever transformation matrix to want to the data (depending on the use of the transformation you may want to apply it to ClipRect as well!)
// Important: Primitives are always added to the list and not culled (culling is done at higher-level by ImGui:: functions), if you use this API a lot consider coarse culling your drawn objects.
// If you want to create ImDrawList instances, pass them ImGui::GetDrawListSharedData() or create and use your own ImDrawListSharedData (so you can use ImDrawList without ImGui)

This is passed down to your render function but not used for CPU-side coarse clipping. Prefer using higher-level ImGui::PushClipRect() to affect logic (hit-testing and widget culling)
// - "p_min" and "p_max" represent the upper-left and lower-right corners of the rectangle.
// - "uv_min" and "uv_max" represent the normalized texture coordinates to use for those corners. Using (0,0)->(1,1) texture coordinates will generally display the entire texture.
