|
* Add a listener object that will get fired for various events regarding
|
|
* customization.
|
|
*
|
|
* @param aListener the listener object to add
|
|
*
|
|
* Not all event handler methods need to be defined.
|
|
* CustomizableUI will catch exceptions. Events are dispatched
|
|
* synchronously on the UI thread, so if you can delay any/some of your
|
|
* processing, that is advisable. The following event handlers are supported:
|
|
* - onWidgetAdded(aWidgetId, aArea, aPosition)
|
|
* Fired when a widget is added to an area. aWidgetId is the widget that
|
|
* was added, aArea the area it was added to, and aPosition the position
|
|
* in which it was added.
|
|
* - onWidgetMoved(aWidgetId, aArea, aOldPosition, aNewPosition)
|
|
* Fired when a widget is moved within its area. aWidgetId is the widget
|
|
* that was moved, aArea the area it was moved in, aOldPosition its old
|
|
* position, and aNewPosition its new position.
|
|
* - onWidgetRemoved(aWidgetId, aArea)
|
|
* Fired when a widget is removed from its area. aWidgetId is the widget
|
|
* that was removed, aArea the area it was removed from.
|
|
*
|
|
* - onWidgetBeforeDOMChange(aNode, aNextNode, aContainer, aIsRemoval)
|
|
* Fired *before* a widget's DOM node is acted upon by CustomizableUI
|
|
* (to add, move or remove it). aNode is the DOM node changed, aNextNode
|
|
* the DOM node (if any) before which a widget will be inserted,
|
|
* aContainer the *actual* DOM container (could be an overflow panel in
|
|
* case of an overflowable toolbar), and aWasRemoval is true iff the
|
|
* action about to happen is the removal of the DOM node.
|
|
* - onWidgetAfterDOMChange(aNode, aNextNode, aContainer, aWasRemoval)
|
|
* Like onWidgetBeforeDOMChange, but fired after the change to the DOM
|
|
* node of the widget.
|
|
*
|
|
* - onWidgetReset(aNode, aContainer)
|
|
* Fired after a reset to default placements moves a widget's node to a
|
|
* different location. aNode is the widget's node, aContainer is the
|
|
* area it was moved into (NB: it might already have been there and been
|
|
* moved to a different position!)
|
|
* - onWidgetUndoMove(aNode, aContainer)
|
|
* Fired after undoing a reset to default placements moves a widget's
|
|
* node to a different location. aNode is the widget's node, aContainer
|
|
* is the area it was moved into (NB: it might already have been there
|
|
* and been moved to a different position!)
|
|
* - onAreaReset(aArea, aContainer)
|
|
* Fired after a reset to default placements is complete on an area's
|
|
* DOM node. Note that this is fired for each DOM node. aArea is the area
|
|
* that was reset, aContainer the DOM node that was reset.
|
|
*
|
|
* - onWidgetCreated(aWidgetId)
|
|
* Fired when a widget with id aWidgetId has been created, but before it
|
|
* is added to any placements or any DOM nodes have been constructed.
|
|
* Only fired for API-based widgets.
|
|
* - onWidgetAfterCreation(aWidgetId, aArea)
|
|
* Fired after a widget with id aWidgetId has been created, and has been
|
|
* added to either its default area or the area in which it was placed
|
|
* previously. If the widget has no default area and/or it has never
|
|
* been placed anywhere, aArea may be null. Only fired for API-based
|
|
* widgets.
|
|
* - onWidgetDestroyed(aWidgetId)
|
|
* Fired when widgets are destroyed. aWidgetId is the widget that is
|
|
* being destroyed. Only fired for API-based widgets.
|
|
* - onWidgetInstanceRemoved(aWidgetId, aDocument)
|
|
* Fired when a window is unloaded and a widget's instance is destroyed
|
|
* because of this. Only fired for API-based widgets.
|
|
*
|
|
* - onWidgetDrag(aWidgetId, aArea)
|
|
* Fired both when and after customize mode drag handling system tries
|
|
* to determine the width and height of widget aWidgetId when dragged to a
|
|
* different area. aArea will be the area the item is dragged to, or
|
|
* undefined after the measurements have been done and the node has been
|
|
* moved back to its 'regular' area.
|
|
*
|
|
* - onCustomizeStart(aWindow)
|
|
* Fired when opening customize mode in aWindow.
|
|
* - onCustomizeEnd(aWindow)
|
|
* Fired when exiting customize mode in aWindow.
|
|
*
|
|
* - onWidgetOverflow(aNode, aContainer)
|
|
* Fired when a widget's DOM node is overflowing its container, a toolbar,
|
|
* and will be displayed in the overflow panel.
|
|
* - onWidgetUnderflow(aNode, aContainer)
|
|
* Fired when a widget's DOM node is *not* overflowing its container, a
|
|
* toolbar, anymore.
|
|
* - onWindowOpened(aWindow)
|
|
* Fired when a window has been opened that is managed by CustomizableUI,
|
|
* once all of the prerequisite setup has been done.
|
|
* - onWindowClosed(aWindow)
|
|
* Fired when a window that has been managed by CustomizableUI has been
|
|
* closed.
|
|
* - onAreaNodeRegistered(aArea, aContainer)
|
|
* Fired after an area node is first built when it is registered. This
|
|
* is often when the window has opened, but in the case of add-ons,
|
|
* could fire when the node has just been registered with CustomizableUI
|
|
* after an add-on update or disable/enable sequence.
|
|
* - onAreaNodeUnregistered(aArea, aContainer, aReason)
|
|
* Fired when an area node is explicitly unregistered by an API caller,
|
|
* or by a window closing. The aReason parameter indicates which of
|
|
* these is the case.
