Detailed Description

A component that resizes its parent component when dragged.

This component forms a bar along one edge of a component, allowing it to be dragged by that edges to resize it.

To use it, just add it to your component, positioning it along the appropriate edge. Make sure you reposition the resizer component each time the parent's size changes, to keep it in the correct position.

Member Enumeration Documentation

enum ResizableEdgeComponent::Edge

Enumerator:

leftEdge	Indicates a vertical bar that can be dragged left/right to move the component's left-hand edge.
rightEdge	Indicates a vertical bar that can be dragged left/right to move the component's right-hand edge.
topEdge	Indicates a horizontal bar that can be dragged up/down to move the top of the component.
bottomEdge	Indicates a horizontal bar that can be dragged up/down to move the bottom of the component.

Constructor & Destructor Documentation

ResizableEdgeComponent::ResizableEdgeComponent	(	Component *	componentToResize,
		ComponentBoundsConstrainer *	constrainer,
		Edge	edgeToResize
	)

Creates a resizer bar.

Pass in the target component which you want to be resized when this one is dragged. The target component will usually be this component's parent, but this isn't mandatory.

Remember that when the target component is resized, it'll need to move and resize this component to keep it in place, as this won't happen automatically.

If the constrainer parameter is non-zero, then this object will be used to enforce limits on the size and position that the component can be stretched to. Make sure that the constrainer isn't deleted while still in use by this object.
