Generic helper, equivalent to old ImGui::CalcListClipping() but stateless

Calculate default item width given value passed to PushItemWidth() or SetNextItemWidth(). The SetNextItemWidth() data is generally cleared/consumed by

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

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

- Get***() functions find pair, never add/allocate. Pairs are sorted so a query is O(log N) - Set***() functions find pair, insertion on demand if mis

Clear all incoming events.

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

Clear CPU-side copy of the texture data.

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.

Note: For multi-threaded rendering, consider using `imgui_threaded_rendering` from https://github.com/ocornut/imgui_club

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

The Collapse button also functions as a Dock Menu button.

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

A little color square. Return true when clicked. FIXME: May want to display/ignore the alpha component in the color display? Yet show it in the toolti

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