Method Detail

selectionUpdate

public void selectionUpdate(SelectionEvent e)

Handler for "Selection" events triggered e.g. by a click on a graphical object (from a given PEDrawingBoard) This takes the following actions:

• marks the active drawing board as dirty and possibly adds a trailing "*" to the frame's title,
• updates widgets states (ie menu items + toolbar buttons),
• eventually notifies interested dockable panels (through the "dockablePanelsMap" hash table) that the state of the Drawing has changed (for instance, say there's a graphical object filled in red and we just selected it -> changes the current active fill colour to red in the attributes editor palette).

Specified by:

selectionUpdate in interface SelectionListener

undoableEditHappened

public void undoableEditHappened(javax.swing.event.UndoableEditEvent e)

Handler for "UndoableEdit" events sourced by PECanvas. Updates undo/redo menu items and corresponding toolbar buttons.

Specified by:

undoableEditHappened in interface javax.swing.event.UndoableEditListener

propertyChange

public void propertyChange(java.beans.PropertyChangeEvent e)

Handler for "PropertyChange" events sources from either PECanvas or its EditorKit. Simply forwards these events to all DockablePanel's which implement the PropertyChangeListener interface, as well as to the attached PEMenuBar.
