how to execute a dialog from popup bar menu item [message #104740]

I would like to execute a dialog to capture information for attributes
before I create a new node on the diagram. I was hoping to hook this
dialog into the create action from the popup bar menu item that GMF
provides for creating nodes on the diagram. Is there any way to do this.

Hi John,

my advice here would be stick with the way GMF is designed by default.
Why do you want to open a dialog? Can't you just create the node with
default values and then (if neccesary) edit the attributes via the
property sheet?

Keep in mind: size properties can be set while creating the node via
mouse gesture (drag). Label properties can be created after creating.
What else do you need?

Regards
Martin

Hello,

You can override CreateElementCommand.

If you want only show dialog without 'cancel' you may override
'doDefaultElementCreation', if you want dialog with 'cancel' you can
override 'doExecuteWithResult'.

Sorry for my English ;>

Martin,

Actually I can't create the node without setting two essential
properties first. That is why I would like to invoke a dialog before
continuing with the creation of the node from the popup bar. I that is
not doable then I will have to disable the popup bar for that node type.
