- likewise io.MousePos and GetMousePos() will use OS coordinates.
If you query mouse positions to interact with non-imgui coordinates you will need to offset them, e.g. subtract GetWindowViewport()->Pos.
- 2025/01/22 (1.91.8) - removed ImGuiColorEditFlags_AlphaPreview (made value 0): it is now the default behavior.
prior to 1.91.8: alpha was made opaque in the preview by default _unless_ using ImGuiColorEditFlags_AlphaPreview. We now display the preview as transparent by default. You can use ImGuiColorEditFlags_AlphaOpaque to use old behavior.
the new flags (ImGuiColorEditFlags_AlphaOpaque, ImGuiColorEditFlags_AlphaNoBg + existing ImGuiColorEditFlags_AlphaPreviewHalf) may be combined better and allow finer controls:
- 2025/01/14 (1.91.7) - renamed ImGuiTreeNodeFlags_SpanTextWidth to ImGuiTreeNodeFlags_SpanLabelWidth for consistency with other names. Kept redirection enum (will obsolete). (#6937)
- 2024/11/27 (1.91.6) - changed CRC32 table from CRC32-adler to CRC32c polynomial in order to be compatible with the result of SSE 4.2 instructions.
As a result, old .ini data may be partially lost (docking and tables information particularly).
