API paste: replace existing selection with passed-in text

returns number of contours

rects array must be big enough to accommodate all characters in the given ranges

note: this routine clips fills that extend off the edges... ideally this wouldn't happen, but it could happen if the truetype glyph bounding boxes are

since most people won't use this, find this table the first time it's needed

x^3 + a*x^2 + b*x + c = 0

tessellate until threshold p is happy... @TODO warped to compensate for non-linear stretching

Set bit n in the array

Use ear-clipping algorithm to triangulate a simple polygon (no self-interaction, no holes). (Reminder: we don't perform any coarse clipping/culling in

No specific ordering/dependency support, will see as needed

- We intentionally avoid using ImVec2 and its math operators here to reduce cost to a minimum for debug/non-inlined builds. - Filled shapes must alway

Important: 'out_list' is generally going to be draw_data->CmdLists, but may be another temporary list as long at it is expected that the result will b

NB: Transfer ownership of 'ttf_data' to ImFontAtlas, unless font_cfg_template->FontDataOwnedByAtlas == false. Owned TTF buffer will be deleted after B

Prior to v1.90 2023/10/16, the BeginChild() function took a 'bool border = false' parameter instead of 'ImGuiChildFlags child_flags = 0'. ImGuiChildFl

Content boundaries max for the window (roughly (0,0)+Size-Scroll), in window-local coordinates. You should never need this. Always use GetCursorScreen

Call directly after the BeginCombo/EndCombo block. The preview is designed to only host non-interactive elements (Experimental, see GitHub issues: #16

BeginDisabled()/EndDisabled() - Those can be nested but it cannot be used to enable an already disabled section (a single BeginDisabled(true) in the s

Could have been called BeginDisabledDisable() but it didn't want to be award nominated for most awkward function name. Ideally we would use a shared e

When this returns true you need to: a) call SetDragDropPayload() exactly once, b) you may render the payload visual/description, c) call EndDragDropSo

We don't use BeginDragDropTargetCustom() and duplicate its code because: 1) we use LastItemData's ImGuiItemStatusFlags_HoveredRect which handles items
