Method Detail

compositeChanged

public void compositeChanged(ChangedEvent event)

This method is called whenever a Composite has been changed but for the change is no specialized callback defined.

Parameters:

event - the ChangedEvent

See Also:

ChangedEvent

compositePreMoving

public void compositePreMoving(MoveEvent event)

This method is called before a Composite is being moved around. Throwing a CompositeEventVetoException prevents movement of the Composite completely.

Parameters:

event - the LineMoveEvent

See Also:

MoveEvent

compositeMoving

public void compositeMoving(MoveEvent event)

This method is called while a Composite is being moved around. Throwing a CompositeEventVetoException prevents movement of the Composite to the actual position. For instance this can be used to avoid that the Composite is being moved to a location that is not acceptable.

Notice that this method is only called while interaction with the Composite is taking place and not when moving it by the interface methods.

Parameters:

event - the MoveEvent

See Also:

MoveEvent

compositePostMoving

public void compositePostMoving(MoveEvent event)

This method is called after a Composite has been moved.

Parameters:

event - the MoveEvent

See Also:

MoveEvent

compositePreResizing

public void compositePreResizing(ResizeEvent event)

This method is called before a Composite is about to be resized. Throwing a CompositeEventVetoException prevents resizement of the Composite completely.

Parameters:

event - the ResizeEvent

See Also:

ResizeEvent

compositeResizing

public void compositeResizing(ResizeEvent event)

This method is called while a Composite is being resized. Throwing a CompositeEventVetoException prevents resizement of the Composite to the actual size. For instance this can be used to avoid that the Composite is being resized to a size that is not acceptable.

Notice that this method is only called while interaction with the Composite is taking place and not when resize it by the interface methods.

Parameters:

event - the ResizeEvent

See Also:

ResizeEvent

compositePostResizing

public void compositePostResizing(ResizeEvent event)

This method is called after a Composite has been resized.

Parameters:

event - the ResizeEvent
