## Detailed Description

Base class for Component::Positioners that are based upon relative coordinates.

## Constructor & Destructor Documentation

## ◆ RelativeCoordinatePositionerBase()

RelativeCoordinatePositionerBase::RelativeCoordinatePositionerBase | ( | Component & |  | ) |

## ◆ ~RelativeCoordinatePositionerBase()

RelativeCoordinatePositionerBase::~RelativeCoordinatePositionerBase | ( |  | ) |
| override

## Member Function Documentation

## ◆ componentMovedOrResized()

void RelativeCoordinatePositionerBase::componentMovedOrResized | ( | Component & | component,
|  | bool | wasMoved,
|  | bool | wasResized )
| override virtual

Called when the component's position or size changes.

Parameters

  component | the component that was moved or resized
  wasMoved | true if the component's top-left corner has just moved
  wasResized | true if the component's width or height has just changed

See also
  Component::setBounds, Component::resized, Component::moved

Reimplemented from ComponentListener.

## ◆ componentParentHierarchyChanged()

void RelativeCoordinatePositionerBase::componentParentHierarchyChanged | ( | Component & | component | ) |
| override virtual

Called to indicate that the component's parents have changed.

When a component is added or removed from its parent, all of its children will produce this notification (recursively - so all children of its children will also be called as well).

Parameters

  component | the component that this listener is registered with

See also
  Component::parentHierarchyChanged

Reimplemented from ComponentListener.

## ◆ componentChildrenChanged()

void RelativeCoordinatePositionerBase::componentChildrenChanged | ( | Component & | component | ) |
| override virtual

Called when the component has children added or removed, or their z-order changes.

Parameters

  component | the component whose children have changed

See also
  Component::childrenChanged, Component::addChildComponent, Component::removeChildComponent

Reimplemented from ComponentListener.

## ◆ componentBeingDeleted()

void RelativeCoordinatePositionerBase::componentBeingDeleted | ( | Component & | component | ) |
| override virtual

Called when the component is in the process of being deleted.

This callback is made from inside the destructor, so be very, very cautious about what you do in here.

In particular, bear in mind that it's the Component base class's destructor that calls this - so if the object that's being deleted is a subclass of Component, then the subclass layers of the object will already have been destructed when it gets to this point!

Parameters

  component | the component that was deleted

Reimplemented from ComponentListener.

## ◆ markersChanged()

void RelativeCoordinatePositionerBase::markersChanged | ( | MarkerList * | markerList | ) |
| override virtual

Called when something in the given marker list changes.

Implements MarkerList::Listener.

## ◆ markerListBeingDeleted()

void RelativeCoordinatePositionerBase::markerListBeingDeleted | ( | MarkerList * | markerList | ) |
| override virtual

Called when the given marker list is being deleted.

Reimplemented from MarkerList::Listener.

## ◆ apply()

void RelativeCoordinatePositionerBase::apply | ( |  | ) |

## ◆ addCoordinate()

bool RelativeCoordinatePositionerBase::addCoordinate | ( | const RelativeCoordinate & |  | ) |

## ◆ addPoint()

bool RelativeCoordinatePositionerBase::addPoint | ( | const RelativePoint & |  | ) |

## ◆ registerCoordinates()

virtual bool RelativeCoordinatePositionerBase::registerCoordinates | ( |  | ) |
| protected pure virtual

## ◆ applyToComponentBounds()

virtual void RelativeCoordinatePositionerBase::applyToComponentBounds | ( |  | ) |
| protected pure virtual
