Calculate text size. Text can be multi-line. Optionally ignore text after a ## marker. CalcTextSize("") should return ImVec2(0.0f, g.FontSize)

t0 = previous time (e.g.: g.Time - g.IO.DeltaTime) t1 = current time (e.g.: g.Time) An event is triggered at: t = 0.0f t = repeat_delay, t = re

Simple word-wrapping for English, not full-featured. Please submit failing cases! This will return the next location to wrap from. If no wrapping if n

Calculate work rect pos/size given a set of offset (we have 1 pair of offset for rect locked from last frame data, and 1 pair for currently building r

Call context hooks (used by e.g. test engine) We assume a small number of hooks so all stored in same array

Clear all incoming events.

Clear all settings (windows, tables, docking etc.)

This will revert window to its initial state, including enabling the ImGuiCond_FirstUseEver/ImGuiCond_Once conditions once more.

Simple version, may lead to an inverted rectangle, which is fine for Contains/Overlaps test but not for display.

Button to close a window

Close the popup we have begin-ed into.

When popups are stacked, clicking on a lower level popups puts focus back to it and close popups above it. This function closes any popups that are ov

CollapsingHeader returns true when opened but do not indent nor push into the ID stack (because of the ImGuiTreeNodeFlags_NoTreePushOnOpen flag). This

Old API, prefer using BeginCombo() nowadays if you can.

User can input math operators (e.g. +100) to edit a numerical values. NB: This is _not_ a full expression evaluator. We should probably add one and re

We record the number of allocation in recent frames, as a way to audit/sanitize our guiding principles of "no allocations on idle/repeating frames"

Verify ABI compatibility between caller code and compiled version of Dear ImGui. This helps detects some build issues. Called by IMGUI_CHECKVERSION().
