juce::Component::Positioner Class Reference

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).

Constructors and Destructors

Positioner()

juce::Component::Positioner::Positioner ( Component & component )

explicitnoexcept

Creates a Positioner which can control the specified component.

Destructor.

Member Functions

getComponent()

Component & juce::Component::Positioner::getComponent ( ) const

noexcept

Returns the component that this positioner controls.

References juce::Component::Component().

applyNewBounds()

virtual void juce::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.
