Method Detail

getTypedElement

public ComponentElement getTypedElement()

Specified by:

getTypedElement in class MgnlElement

editComponent

public void editComponent()

Specified by:

editComponent in interface ComponentListener

getLabel

public String getLabel()

Specified by:

getLabel in interface ComponentListener

hasEditButton

public boolean hasEditButton()

Specified by:

onMoveStart

public void onMoveStart(boolean isDrag)

Callback for ComponentBar when starting a drag or move event. Depending on whether it is a drag or a move it will either notify the server by firing a ComponentStartMoveEvent or register the handlers in doStartMove(boolean).

Specified by:

onMoveStart in interface ComponentListener

Parameters:

isDrag - whether we are dragging the component or moving it

doStartMove

public void doStartMove(boolean isDrag)

Registers the sibling components as move targets and registers a handler for ComponentStopMoveEvent on the source component which will call sortComponent(MgnlComponent).

Parameters:

isDrag - whether we are dragging the component or moving it

onMoveStop

public void onMoveStop()

Callback for ComponentBar targets when a move or drag event is dropped on or moved to this target. Fires ComponentStopMoveEvent to notify the system. Holds itself as payload for handling by the source, see handler registered in doStartMove(boolean).

Specified by:

onMoveStop in interface ComponentListener

onMoveCancel

public void onMoveCancel()

Callback for ComponentBar source when a drag is stopped. Fires ComponentStopMoveEvent to notify the system about the cancel. Will cause target components to unregister themselves as targets.

Specified by:
