Detailed Description

A rect allocator specifically for ImGui windows.

Member Function Documentation

invalidateClosedWindows()

MRVIEWER_API void MR::UI::WindowRectAllocator::invalidateClosedWindows

(

)

Call this once at the begining of ImGui frame, to remove all closed windows from entries list.

setFreeNextWindowPos()

MRVIEWER_API void MR::UI::WindowRectAllocator::setFreeNextWindowPos	(	const char *	expectedWindowName,
		ImVec2	defaultPos,
		ImGuiCond	cond = ImGuiCond_Appearing,
		ImVec2	pivot = ImVec2() )

Call this before drawing a window. expectedWindowName must match the window name. The remaining parameters are forwarded to ImGui::SetNextWindowPos(), expect for one time where we find a free rect and use it instead. cond must not be ImGuiCond_Always (aka 0), in that case we just forward the arguments and don't try to find a rect. We automatically avoid all windows with [rect_allocator_ignore] anywhere after ## in the name.
