drawing temporary figure for selection [message #227558] Tue, 05 December 2006 10:45 Go to next message

Hi everybody,

When I click on an icon in one of my EditParts figure I'd like to show a
new temporary figure, which list some values. The user should now be able
to select a certain value from the list. After selecting a value this
figure is supposed to be deleted. Also it's supposed to be deleted
whenever I click somwhere else in the workbench. Does anybody know how I
could accomplish this or how this is done the best way?

Cheers,

Dan

Hi,

You can try overriding your SelectionEditPolicy and draw this extra figure
in the feedback layer when you draw the selection handles and etc. Install
mouse listeners on that figure or it's sub-figures this should allow you
to react to various user actions properly.

Cheers,
Alex

Thanks for your answer. I already acomplished to react to user selections.
My main problem is to get informed, when clicking somewhere else in the
workbench but in the graphical editor. I.e. on the Eclipse Edit Menu,
because then, the temporary figure has to be hidden as well. I need
something like an event for focus lost or something like that.

Thanks,

Dan
