Function Documentation

ComputePopupFitInRect()

SLATECORE_API UE::Slate::FDeprecateVector2DResult ComputePopupFitInRect	(	const FSlateRect &	InAnchor,
		const FSlateRect &	PopupRect,
		const EOrientation &	Orientation,
		const FSlateRect &	RectToFit,
		bool	bAllowFlip = true
	)

Given information about a popup and the space available for displaying that popup, compute best placement for it.

Parameters

InAnchor	Area relative to which popup is being created (e.g. the button part of a combo box)
PopupRect	Proposed placement of popup; position may require adjustment.
Orientation	Are we trying to show the popup above/below or left/right relative to the anchor?
RectToFit	The space available for showing this popup; we want to fit entirely within it without clipping.
bAllowFlip	Determines whether the popup can be flipped to the other side of the anchor when there is no space on the screen for it to fit at its preferred position.

Returns

A best position within the RectToFit such that none of the popup clips outside of the RectToFit.
