@ -39,6 +39,8 @@ Breaking Changes:
- Removed unncessary ID (first arg) of ImFontAtlas::AddCustomRectRegular() function. Please
note that this is a Beta api and will likely be reworked to support multi-monitor multi-DPI.
- Renamed OpenPopupOnItemClick() to OpenPopupContextItem(). Kept inline redirection function (will obsolete).
- Removed BeginPopupContextWindow(const char*, int mouse_button, bool also_over_items) in favor
of BeginPopupContextWindow(const char*, ImGuiPopupFlags flags) with ImGuiPopupFlags_NoOverItems.
- Removed CalcItemRectClosestPoint() entry point which was made obsolete and asserting in December 2017.
Other Changes:
@ -54,6 +56,13 @@ Other Changes:
Set to an intermediary value to toggle behavior based on width (same as Firefox).
- Tab: Added a ImGuiTabItemFlags_NoTooltip flag to disable the tooltip for individual tab item
(vs ImGuiTabBarFlags_NoTooltip for entire tab bar). [@Xipiryon]
- Popups: All functions capable of opening popups (OpenPopup*, BeginPopupContext*) now take a new
ImGuiPopupFlags sets of flags instead of a mouse button index. The API is automatically backward
compatible as ImGuiPopupFlags is guaranteed to hold mouse button index in the lower bits.
- Popups: Added ImGuiPopupFlags_NoOpenOverExistingPopup for OpenPopup*/BeginPopupContext* functions
to first test for the presence of another popup at the same level.
- Popups: Added ImGuiPopupFlags_NoOpenOverItems for BeginPopupContextWindow() - similar to testing
for !IsAnyItemHovered() prior to doing an OpenPopup.
- Popups: Added ImGuiPopupFlags_AnyPopupId and ImGuiPopupFlags_AnyPopupLevel flags for IsPopupOpen(),
allowing to check if any popup is open at the current level, if a given popup is open at any popup
level, if any popup is open at all.
