MISSION STATEMENT
- easy to use to create code-driven and data-driven tools
- easy to use to create adhoc short-lived tools and long-lived, more elaborate tools
- easy to hack and improve
- minimize screen real-estate usage
- minimize setup and maintainance
- minimize state storage on user side
- portable, minimize dependencies, run on target (consoles, etc.)
- efficient runtime (nb- we do allocate when "growing" content - creating a window / opening a tree node for the first time, etc. - but a typical frame won't allocate anything)
- read about immediate-mode GUI principles @ http://mollyrocket.com/861, http://mollyrocket.com/forums/index.html
Designed for developers and content-creators, not the typical end-user! Some of the weaknesses includes:
- doesn't look fancy, doesn't animate
- limited layout features, intricate layouts are typically crafted in code
- assume ASCII text, using strlen() and [] operators, etc
- occasionally use statically sized buffers for string manipulations - won't crash, but some long text may be clipped
USER GUIDE
- double-click title bar to collapse window
- click upper right corner to close a window, available when 'bool* open' is passed to ImGui::Begin()
- click and drag on lower right corner to resize window
- click and drag on any empty space to move window
- double-click/double-tap on lower right corner grip to auto-fit to content
- TAB/SHIFT+TAB to cycle through keyboard editable fields
- use mouse wheel to scroll
- use CTRL+mouse wheel to zoom window contents (if IO.FontAllowScaling is true)
- CTRL+Click on a slider to input value as text
- text editor:
- Hold SHIFT or use mouse to select text.
- CTRL+Left/Right to word jump
- CTRL+Shift+Left/Right to select words
- CTRL+A our Double-Click to select all
- CTRL+X,CTRL+C,CTRL+V to use OS clipboard
- CTRL+Z,CTRL+Y to undo/redo
- ESCAPE to revert text to its original value
- You can apply arithmetic operators +,*,/ on numerical values. Use +- to subtract (because - would set a negative value!)
PROGRAMMER GUIDE
- your code creates the UI, if your code doesn't run the UI is gone! == dynamic UI, no construction step, less data retention on your side, no state duplication, less sync, less errors.
- see ImGui::ShowTestWindow() for user-side sample code
- getting started:
- initialisation: call ImGui::GetIO() and fill the 'Settings' data.
- every frame:
1/ in your mainloop or right after you got your keyboard/mouse info, call ImGui::GetIO() and fill the 'Input' data, then call ImGui::NewFrame().
2/ use any ImGui function you want between NewFrame() and Render()
3/ ImGui::Render() to render all the accumulated command-lists. it will cack your RenderDrawListFn handler set in the IO structure.
- all rendering information are stored into command-lists until ImGui::Render() is called.
- effectively it means you can create widgets at any time in your code, regardless of "update" vs "render" considerations.
- a typical application skeleton may be:
// Application init
// TODO: Fill all 'Settings' fields of the io structure
ImGuiIO& io = ImGui::GetIO();
io.DisplaySize.x = 1920.0f;
io.DisplaySize.y = 1280.0f;
io.DeltaTime = 1.0f/60.0f;
io.IniFilename = "imgui.ini";
// Application mainloop
while (true)
{
// 1/ get low-level input
// e.g. on Win32, GetKeyboardState(), or poll your events, etc.
// 2/ TODO: Fill all 'Input' fields of io structure and call NewFrame
ImGuiIO& io = ImGui::GetIO();
io.MousePos = ...
io.KeysDown[i] = ...
ImGui::NewFrame();
// 3/ most of your application code here - you can use any of ImGui::* functions between NewFrame() and Render() calls
GameUpdate();
GameRender();
// 4/ render & swap video buffers
ImGui::Render();
// swap video buffer, etc.
}
- some widgets carry state and requires an unique ID to do so.
- unique ID are typically derived from a string label, an indice or a pointer.
- use PushID/PopID to easily create scopes and avoid ID conflicts. A Window is also an implicit scope.
- when creating trees, ID are particularly important because you want to preserve the opened/closed state of tree nodes.
depending on your use cases you may want to use strings, indices or pointers as ID. experiment and see what makes more sense!
e.g. When displaying a single object, using a static string as ID will preserve your node open/closed state when the targetted object change
e.g. When displaying a list of objects, using indices or pointers as ID will preserve the node open/closed state per object
- when passing a label you can optionally specify extra unique ID information within the same string using "##". This helps solving the simpler collision cases.
e.g. "Label" display "Label" and uses "Label" as ID
e.g. "Label##Foobar" display "Label" and uses "Label##Foobar" as ID
e.g. "##Foobar" display an empty label and uses "##Foobar" as ID
- if you want to use a different font than the default
- create bitmap font data using BMFont. allocate ImGui::GetIO().Font and use ->LoadFromFile()/LoadFromMemory(), set ImGui::GetIO().FontHeight
- load your texture yourself. texture *MUST* have white pixel at UV coordinate 'IMGUI_FONT_TEX_UV_FOR_WHITE' (you can #define it in imconfig.h), this is used by solid objects.
- tip: the construct 'if (IMGUI_ONCE_UPON_A_FRAME)' will evaluate to true only once a frame, you can use it to add custom UI in the middle of a deep nested inner loop in your code.
- tip: you can call Render() multiple times (e.g for VR renders), up to you to communicate the extra state to your RenderDrawListFn function.
- tip: you can create widgets without a Begin/End block, they will go in an implicit window called "Debug"
ISSUES AND TODO-LIST
- misc: merge ImVec4 / ImGuiAabb, they are essentially duplicate containers
- window: autofit is losing its purpose when user relies on any dynamic layout (window width multiplier, column). maybe just discard autofit?
- window: support horizontal scroll
- window: fix resize grip scaling along with Rounding style setting
- widgets: switching from "widget-label" to "label-widget" would make it more convenient to integrate widgets in trees
- widgets: clip text? hover clipped text shows it in a tooltip or in-place overlay
- main: make IsHovered() more consistent for various type of widgets, widgets with multiple components, etc. also effectively IsHovered() region sometimes differs from hot region, e.g tree nodes
- main: make IsHovered() info stored in a stack? so that 'if TreeNode() { Text; TreePop; } if IsHovered' return the hover state of the TreeNode?
- scrollbar: use relative mouse movement when first-clicking inside of scroll grab box.
- scrollbar: make the grab visible and a minimum size for long scroll regions
- input number: optional range min/max
- input number: holding [-]/[+] buttons should increase the step non-linearly
- input number: rename Input*() to Input(), Slider*() to Slider() ?
- layout: clean up the InputFloatN/SliderFloatN/ColorEdit4 horrible layout code. item width should include frame padding, then we can have a generic horizontal layout helper.
- columns: declare column set (each column: fixed size, %, fill, distribute default size among fills)
- columns: columns header to act as button (~sort op) and allow resize/reorder
- columns: user specify columns size
- combo: turn child handling code into popup helper
- list selection, concept of a selectable "block" (that can be multiple widgets)
- menubar, menus
- plot: make it easier for user to draw into the graph (e.g: draw basis, highlight certain pointsm, 2d plots, multiple plots)
- plot: "smooth" automatic scale, user give an input 0.0(full user scale) 1.0(full derived from value)
- plot: add a helper e.g. Plot(char* label, float value, float time_span=2.0f) that stores values and Plot them for you - probably another function name. and/or automatically allow to plot ANY displayed value (more reliance on stable ID)
- file selection widget -> build the tool in our codebase to improve model-dialog idioms (may or not lead to ImGui changes)
- slider: allow using the [-]/[+] buttons used by InputFloat()/InputInt()
- slider: initial absolute click is unprecise. change to relative movement slider? hide mouse cursor, allow more precise input using less screen-space.
- text edit: centered text for slider or input text to it matches typical positionning.
- text edit: flag to disable live update of the user buffer.
- text edit: field resize behaviour - field could stretch when being edited? hover tooltip shows more text?
- text edit: pasting text into a number box should filter the characters the same way direct input does
- text edit: allow code to catch user pressing Return (perhaps through disable live edit? so only Return apply the final value, also allow catching Return if value didn't changed)
- settings: write more decent code to allow saving/loading new fields
- log: be able to right-click and log a window or tree-node into tty/file/clipboard?
- filters: set a current filter that tree node can automatically query to hide themselves
- filters: handle wildcards (with implicit leading/trailing *), regexps
- shortcuts: add a shortcut api, e.g. parse "&Save" and/or "Save (CTRL+S)", pass in to widgets or provide simple ways to use (button=activate, input=focus)
- input: keyboard: full keyboard navigation and focus.
- input: support trackpad style scrolling & slider edit.
- misc: not thread-safe
- misc: double-clicking on title bar to minimize isn't consistent, perhaps move to single-click on left-most collapse icon?
- optimisation/render: use indexed rendering
- optimisation/render: move clip-rect to vertex data? would allow merging all commands
- optimisation/render: merge command-list of all windows into one command-list?
- optimisation/render: font exported by bmfont is not tight fit on vertical axis, incur unneeded pixel-shading cost.
- optimisation: turn some the various stack vectors into statically-sized arrays
- optimisation: better clipping for multi-component widgets
- optimisation: specialize for height based clipping first (assume widgets never go up + height tests before width tests?)
