## 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.

## Constructor & Destructor Documentation

## ◆ BorderedComponentBoundsConstrainer()

BorderedComponentBoundsConstrainer::BorderedComponentBoundsConstrainer | ( |  | ) |
| default

Default constructor.

## 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
