Adding context menu for Draw2d figures [message #234119]

How do we add context menu to draw2d figures. I do realize that this
question has been asked before on the newsgroup and the answer given was:

"Popup menus can be invoked with the keyboard too (Shift+F10). Therefore
you
must have a notion of what is selected, and base your popup menu on
selection, not mouse location. There is no notion of selection in draw2d,
only in GEF."

Can anyone provide more details on how to do this. So if I have a
FigureCanvas and I add bunch for figures to it, what should I do. I am
thinking of somehow using hte findFigure methods in FigureCanvas to find
out which figure was selected. So I only need to find the coordinates
where the right mouse click occured? Is there a better way to do this?

Hi,

Just ask your viewer for selected editparts, i.e. use
EditPartViewer#getSelectedEditParts().
Hope this helps.

Cheers,
Alex

the problem is that i am not using GEf. I am only using the draw2d apis
which means that I am using SWT and stuff and only using FigureCanvas and
other figures that are added to teh FigureCanvas

Hi,

You have the good idea. The only way to add the context menu is to add
your own inside your own listener. 2 solutions :

- the first you mentioned is to add a mouse listener on the canvas, and
find wich figure was selected.

- the second is to add a mouse listener to the figures that need context
menu (may be use a singleton listener to avoid lot of listener creation)

Hope this can help
