Need getSingleClickFeature() clarification [message #1777360]

In JavaDoc it says
Quote:

Returns a feature which will be executed at at a single click on an already selected shape...

Why such a restriction? This means that the executed when PE is clicked and then clicked again, why can't this method be called when PE is clicked the first time, without being selected. Is there another method that does single click without prior selection?

Thanks,
Alex

Alex,

the single click feature was build in the same way as the already existing double click feature. Besides Graphiti always operates on selected shapes.

If you are interested in the first click you might hook into the selection by overriding IToolBehaviorProvider.getSelection(...) method, but there is no feature that is triggered at that time.

HTH,
Michael

Thanks Michael. Can I distinguish between hover over and mouse click in getSelection(...)? It's triggered even when mouse pointer is hovered over the figure.

Ah yes, right. This is used for the hover feedback as well.

Hm, I'm afraid you cannot distiguish these cases.
