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

Typical usage would be: if (!ImGui::IsWindowHovered(ImGuiHoveredFlags_AnyWindow | ImGuiHoveredFlags_AllowWhenBlockedByActiveItem)) if (ImGui::BeginDra

Pseudo-tooltip. Follow mouse until Ctrl is held. When Ctrl is held we lock position, allowing to click it.

Lock horizontal starting position + capture group bounding box into one "item" (so you can use IsItemHovered() or layout primitives such as SameLine()

This is essentially a thin wrapper to using BeginChild/EndChild with the ImGuiChildFlags_FrameStyle flag for stylistic changes + displaying a label. T

Attention! BeginPopup() adds default flags when calling BeginPopupEx()!

If 'p_open' is specified for a modal popup window, the popup will have a regular close button which will close the popup. Note that popup visibility s

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