branch pressing arrow keys while dragging a window from a tab could trigger an assert. (#3025)
|
||||
- ColorButton: Added ImGuiColorEditFlags_NoBorder flag to remove the border normally enforced

||||
by default for standalone ColorButton.

|
||||
- BeginMenu: Using same ID multiple times appends content to a menu. (#1207) [@rokups]
|
||||
- BeginMenu: Fixed a bug where SetNextWindowXXX data before a BeginMenu() would not be cleared
|
||||
when the menu is not open. (#3030)
|
||||
- InputText: Fixed password fields displaying ASCII spaces as blanks instead of using the '*'
|
||||
glyph. (#2149, #515)
|
||||
- Added optional support for Unicode plane 1-16 (#2538, #2541, #2815) [@cloudwu, @samhocevar]
|
||||
- Compile-time enable with '#define ImWchar ImWchar32' in imconfig.h.
|
||||
- Generally more consistent support for unsupported codepoints (0xFFFD), in particular when
|
||||
using the default, non-fitting characters will be turned into 0xFFFD instead of being ignored.
|
||||
- Surrogate pairs are supported when submitting UTF-16 data via io.AddInputCharacterUTF16(),
|
||||
allowing for more complete CJK input.
|
||||
- sizeof(ImWchar) goes from 2 to 4. IM_UNICODE_CODEPOINT_MAX goes from 0xFFFF to 0x10FFFF.
|
||||
- Various structures such as ImFont, ImFontGlyphRangesBuilder will use more memory, this
|
||||
is currently not particularly efficient.
|
||||
- Window: Fixed a bug with child window inheriting ItemFlags from their parent when the child
|
||||
window also manipulate the ItemFlags stack. (#3024) [@Stanbroek]
|
||||
- Font: Fixed non-ASCII space occasionally creating unnecessary empty polygons.

ImGui_ImplWin32_GetDpiScaleForMonitor() helpers functions (backported from the docking branch).
|
||||
Those functions makes it easier for example apps to support hi-dpi features without setting up
|
||||
a manifest.

- Backends: Win32: Calling AddInputCharacterUTF16() from WM_CHAR message handler in order to support
|
||||
high-plane surrogate pairs. (#2815) [@cloudwu, @samhocevar]
|

- Backends: SDL: Added ImGui_ImplSDL2_InitForMetal() for API consistency (even though the function

currently does nothing).
