juce::BorderedComponentBoundsConstrainer Class Reference

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.
