Member Function Documentation

◆ componentMovedOrResized()

void RelativeCoordinatePositionerBase::componentMovedOrResized ( Component component,
bool  wasMoved,
bool  wasResized 
)
overridevirtual

Called when the component's position or size changes.

Parameters
componentthe component that was moved or resized
wasMovedtrue if the component's top-left corner has just moved
wasResizedtrue 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)
overridevirtual

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
componentthe component that this listener is registered with
See also
Component::parentHierarchyChanged

Reimplemented from ComponentListener.

◆ componentChildrenChanged()

void RelativeCoordinatePositionerBase::componentChildrenChanged ( Component component)
overridevirtual

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

Parameters
componentthe component whose children have changed
See also
Component::childrenChanged, Component::addChildComponent, Component::removeChildComponent

Reimplemented from ComponentListener.

◆ componentBeingDeleted()

void RelativeCoordinatePositionerBase::componentBeingDeleted ( Component component)
overridevirtual

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
componentthe component that was deleted

Reimplemented from ComponentListener.

◆ markersChanged()

void RelativeCoordinatePositionerBase::markersChanged ( MarkerList markerList)
overridevirtual

Called when something in the given marker list changes.

Implements MarkerList::Listener.

◆ markerListBeingDeleted()

void RelativeCoordinatePositionerBase::markerListBeingDeleted ( MarkerList markerList)
overridevirtual

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 ( )

◆ applyToComponentBounds()
