Detailed Description

A rect allocator for labels.

Member Function Documentation

createRect()

MRVIEWER_API ImVec2 MR::UI::LabelRectAllocator::createRect	(	ViewportId	viewportId,
		std::string	id,
		ImVec2	pos,
		ImVec2	size,
		bool	forceExactPosition = false )

Call this every frame to maintain a rectangle. Using the same ID more than once per frame triggers an assertion. Returns the free position closest to pos. Separate label lists are maintained per viewport. If forceExactPosition == true, the input position is returned unchanged, but the rect is still added to the internal list to push away other rects.
