Detailed Description

Gets informed about changes to a component's hierarchy or position.

To monitor a component for changes, register a subclass of ComponentListener with the component using Component::addComponentListener().

Be sure to deregister listeners before you delete them!

Component::addComponentListener, Component::removeComponentListener

Constructor & Destructor Documentation

◆ ~ComponentListener()

virtual juce::ComponentListener::~ComponentListener ( )
inlinevirtual

Destructor.

Member Function Documentation

◆ componentBeingDeleted()

void ComponentListener::componentBeingDeleted ( Component component)
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!

Reimplemented in juce::ComponentMovementWatcher, juce::ModalComponentManager::ModalItem, and juce::RelativeCoordinatePositionerBase.

◆ componentBroughtToFront()

void ComponentListener::componentBroughtToFront ( Component component)
virtual

Called when the component is brought to the top of the z-order.

Parameters
componentthe component that was moved
See also
Component::toFront, Component::broughtToFront

◆ componentChildrenChanged()

void ComponentListener::componentChildrenChanged ( Component component)
virtual

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 in juce::RelativeCoordinatePositionerBase.

◆ componentMovedOrResized()

void ComponentListener::componentMovedOrResized ( Component component,
bool  wasMoved,
bool  wasResized 
)
virtual

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 in juce::Label, juce::Viewport, juce::ComponentMovementWatcher, and juce::RelativeCoordinatePositionerBase.

◆ componentNameChanged()

void ComponentListener::componentNameChanged ( Component component)
virtual

Called when the component's name is changed.

See also
Component::setName, Component::getName

Reimplemented in juce::MultiDocumentPanel.

◆ componentParentHierarchyChanged()

void ComponentListener::componentParentHierarchyChanged ( Component component)
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
componentthe component that this listener is registered with
See also
Component::parentHierarchyChanged

Reimplemented in juce::Label, juce::ComponentMovementWatcher, and juce::RelativeCoordinatePositionerBase.

◆ componentVisibilityChanged()

void ComponentListener::componentVisibilityChanged ( Component component)
virtual

Called when the component is made visible or invisible.

Parameters
componentthe component that changed
See also
Component::setVisible

Reimplemented in juce::Label, and juce::ComponentMovementWatcher.
