areaInvalidated

public void areaInvalidated(FigureEvent e)

Description copied from interface: FigureListener

Sent when the drawing area used by the figure needs to be repainted.

Specified by:

areaInvalidated in interface FigureListener

attributeChanged

public void attributeChanged(FigureEvent e)

Description copied from interface: FigureListener

Sent when an attribute of the figure has changed.

Specified by:

attributeChanged in interface FigureListener

figureHandlesChanged

public void figureHandlesChanged(FigureEvent e)

Description copied from interface: FigureListener

Sent when handles of a Figure have been added, removed or replaced.

DrawingViews listen to this event to repopulate the Handles.

A Figure should not fire this event, if just the state or the location of Handle has changed.

Specified by:

figureHandlesChanged in interface FigureListener

figureChanged

public void figureChanged(FigureEvent e)

Description copied from interface: FigureListener

Sent when the geometry (for example the bounds) of the figure has changed.

Specified by:

figureChanged in interface FigureListener

figureAdded

public void figureAdded(FigureEvent e)

Description copied from interface: FigureListener

Sent when a figure was added to a drawing.

Specified by:

figureAdded in interface FigureListener

figureRemoved

public void figureRemoved(FigureEvent e)

Description copied from interface: FigureListener

Sent when a figure was removed from a drawing.

Specified by:

figureRemoved in interface FigureListener

figureRequestRemove

public void figureRequestRemove(FigureEvent e)

Description copied from interface: FigureListener

Sent when the figure requests to be removed from a drawing.

Specified by:

figureRequestRemove in interface FigureListener

setEditor

public void setEditor(DrawingEditor newValue)

Sets the drawing editor. This must be set to a non-null value to make the attribute field functional.

getEditor

public DrawingEditor getEditor()

setView

public void setView(DrawingView newValue)

Sets the drawing view. Setting this to a non-null value, makes the attribute field local to the drawing view. Setting this to null, makes the attribute field global to all drawing views in the drawing editor.

getView

public DrawingView getView()

getCurrentView

public DrawingView getCurrentView()

dispose

public void dispose()
