Here is a change-log of API breaking changes, if you are using one of the functions listed, expect to have to fix some code.
|
||||
Also read releases logs https://github.com/ocornut/imgui/releases for more details.
|
||||
|
||||
- 2017/11/02 (1.53) - marked IsRootWindowOrAnyChildHovered() as obsolete is favor of using IsWindowHovered(ImGuiHoveredFlags_FlattenChilds);
|
||||
- 2017/10/24 (1.52) - renamed IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCS/IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCS to IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCTIONS/IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCTIONS for consistency.
|
||||
- 2017/10/20 (1.52) - changed IsWindowHovered() default parameters behavior to return false if an item is active in another window (e.g. click-dragging item from another window to this window). You can use the newly introduced IsWindowHovered() flags to requests this specific behavior if you need it.
|
||||
- 2017/10/20 (1.52) - marked IsItemHoveredRect()/IsMouseHoveringWindow() as obsolete, in favor of using the newly introduced flags for IsItemHovered() and IsWindowHovered(). See https://github.com/ocornut/imgui/issues/1382 for details.
