Detailed Description

Base class for objects that can be used to automatically position a component according to some kind of algorithm.

The component class simply holds onto a reference to a Positioner, but doesn't actually do anything with it - all the functionality must be implemented by the positioner itself (e.g. it might choose to watch some kind of value and move the component when the value changes).

Constructor & Destructor Documentation

Component::Positioner::Positioner

(

Component &

component

)

[explicit]

Creates a Positioner which can control the specified component.

virtual Component::Positioner::~Positioner

(

)

[virtual]

Destructor.

Member Function Documentation

Component& Component::Positioner::getComponent

(

)

const

Returns the component that this positioner controls.

virtual void Component::Positioner::applyNewBounds

(

const Rectangle< int > &

newBounds

)

[pure virtual]

Attempts to set the component's position to the given rectangle.

Unlike simply calling Component::setBounds(), this may involve the positioner being smart enough to adjust itself to fit the new bounds, e.g. a RelativeRectangle's positioner may try to reverse the expressions used to make them fit these new coordinates.
