Most of you should be familiar with Shape.
I implemented public void performRequest(Request req) for
shapeTreeEditPart,
hoping to do something when some nodes in the outline treeview are selected
or double-clicked.
The code is like this: (ENV: WindowsXP, Eclipse 3.1M7, JRE1.5, RCPed
Shape-Plugin)
void performRequest(Request req){
if (REQ_SELECTION.equals(req.getType())){
doMySelection();
}
else if (REQ_OPEN.equals(req.getType())){
doMyOpen();
}
}
However, doMySelection() and doMyOpen() were never called when debugging,
even though I selected or double-clicked on the nodes in the outline tree.
Does someone have any idea to get the requests?
Thanks,
Miaohua Xu

Well, I have
installEditPolicy(EditPolicy.SELECTION_FEEDBACK_ROLE,
new CallflowSelectionEditPolicy());
in my createEditPolicies() method and I have those requests.
Try to see what is req anyway?
What type do You get?

Hope that helps, Greg

Thank you for your reply.
I tried that and did get breakpoint in SelectionEditPolicy.showSelection()
if a node was selected. But still can't to handle double-click because still
no REQ_OPEN and REQ_SELECTION found in performRequest(Request req).
Actually I didn't find any request. But I don't think it's because
EditPolicies were not installed. In another view of my program, there is no
editpolicy handling REQ_OPEN, either, but I got REQ_OPEN in that editpart's
performRequest(). Is it because the outline TreeViewer has handled many
requests so that it doesn't dispatch them?
Thanks,

Thank you for your reply!
I am guessing the outline TreeViewer has handled such request so that it
doesn't dispatch them. Could you please point out a direction for me? Say,
shall I look into the source code of treeViewer? or something else?
Additional, what do you mean by saying "pick one place/thread to discuss
this problem"? I am kind of new to Eclipse.
Thanks!
