hi!
I've got the following code:
RectangleFigure node1 = new RectangleFigure();
node1.addMouseListener(new MouseListener.Stub() {
public void mousePressed(MouseEvent event) {
if (event.button == 3) {
classMenu.setVisible(true);
}
}
});
classMenu = new Menu (shell, SWT.POP_UP);
item = new MenuItem (classMenu, SWT.PUSH);
item.setText ("Delete");
classMenu.addListener (SWT.Show, new Listener () {
public void handleEvent (Event event) {
System.out.println("here we are..");
}
});
this works well, but when the popup menu is shown I must know which control
was "active" (the object that the user has pushed..).. When I call a
function (not implemented in the source code above) from the menu (as an
example "delete") I have to know which control I should remove... What's the
best way to do this?
thanks for any help!
Remo

Neither does TreeItem. Figures are not meant to be lightweight versions of
SWT Controls. There is no short definition, but they are objects which
layout, paint, and can be hit-tested.
If you want to include the concept of selection, this is one thing that GEF
adds to draw2d. An EditPart is the unit of selection, and EditPartViewers
maintain the set of selected editparts.
