create/remove handles on Enter/Exit an editPart [message #175262] Mon, 04 April 2005 06:58 Go to next message

Hello,

I am interested to put around a shape some handles as I enter in a shape
(when I exit the shape I remove the handles).
I have written some pieces of code to detect (in a policy) in the method
showTargetRequest(request) the incoming REQ_SELECTION, and I put the
different Handles (they are over the shape as suggested in an ealier
post). As I arrive over a handle it disappears (and it try to reappear
as I am still over the underlying shape).
I guess that the selection Tool has founded something (It is perhaps the
freeFormLayout I see in the debugger) which is different as the original
shape and the Tool sends a handleExitingEditPart () to the shape editPart.

My expected behaviour is to put the handle around the shape as I enter
(without any selection) and be able to click one to create a command.

thank you

To prevent the editpart exit, register the handles as part of the editpart
in the viewer's visualPartMap.

If this doesn't help, open a bug

Dear Randy,

Just two words about your suggestion: It works.

I have added in constructor of the Handle this call:

owner.getViewer().getVisualPartMap().put(this, owner);

I know that I have later to unRegister() this visual but this is easy.

Just a last question… How could I found my self this information in the
documentation ?
OK, I see (yesterday) that the viewer is responsible to the hittesting,
but finding who is registered is not easy, registerVisual() is really
hidden in the editPart framework, and I never think to look at this aspect.

Really thank you for this valuable reply.
