Detailed Description

A ComponentBoundsConstrainer that can be used to add a constant border onto another ComponentBoundsConstrainer.

This is useful when trying to constrain the size of a resizable window or other component that wraps a constrained component, such as a plugin editor.

Member Function Documentation

getWrappedConstrainer()

virtual ComponentBoundsConstrainer * BorderedComponentBoundsConstrainer::getWrappedConstrainer ( ) const

pure virtual

Returns a pointer to another constrainer that will be used as the base for any resizing operations.

getAdditionalBorder()

virtual BorderSize< int > BorderedComponentBoundsConstrainer::getAdditionalBorder ( ) const

pure virtual

Returns the border that should be applied to the constrained bounds.

checkBounds()

void BorderedComponentBoundsConstrainer::checkBounds ( Rectangle< int > & bounds, const Rectangle< int > & previousBounds, const Rectangle< int > & limits, bool isStretchingTop, bool isStretchingLeft, bool isStretchingBottom, bool isStretchingRight )

overridevirtual

This callback changes the given coordinates to impose whatever the current constraints are set to be.

Parameters

bounds	the target position that should be examined and adjusted
previousBounds	the component's current size
limits	the region in which the component can be positioned
isStretchingTop	whether the top edge of the component is being resized
isStretchingLeft	whether the left edge of the component is being resized
isStretchingBottom	whether the bottom edge of the component is being resized
isStretchingRight	whether the right edge of the component is being resized

Reimplemented from ComponentBoundsConstrainer.
