|
||||
|
||||
Breaking Changes:
|
||||
|
||||
- ImDrawList: upgraded AddPolyline()/PathStroke()'s "bool closed" parameter to use "ImDrawFlags flags".
|
||||
The matching ImDrawFlags_Closed value is guaranteed to always stay == 1 in the future.
|
||||
bool closed = false ----> use ImDrawFlags_None, or 0
|
||||
bool closed = true ----> use ImDrawFlags_Closed
|
||||
Difference may not be noticeable for most but zealous type-checking tools may report a need to change.
|
||||
- Style: renamed rarely used style.CircleSegmentMaxError (old default = 1.60f)
|
||||
to style.CircleTessellationMaxError (new default = 0.30f) as its meaning changed. (#3808) [@thedmd]
|
||||
- Win32+MinGW: Re-enabled IME functions by default even under MinGW. In July 2016, issue #738 had me incorrectly

- 2021/03/10 (1.82) - upgraded ImDrawList::AddPolyline() and PathStroke() "bool closed" parameter to "ImDrawFlags flags". The matching ImDrawFlags_Closed value is guaranteed to always stay == 1 in the future.
|
||||
- 2021/02/22 (1.82) - win32+mingw: Re-enabled IME functions by default even under MinGW. In July 2016, issue #738 had me incorrectly disable those default functions for MinGW. MinGW users should: either link with -limm32, either set their imconfig file with '#define IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCTIONS'.
|
||||
- 2021/02/17 (1.82) - renamed rarely used style.CircleSegmentMaxError (old default = 1.60f) to style.CircleTessellationMaxError (new default = 0.30f) as the meaning of the value changed.
|
||||
- 2021/02/03 (1.81) - renamed ListBoxHeader(const char* label, ImVec2 size) to BeginListBox(). Kept inline redirection function (will obsolete).
