Re: [udig-devel] How to make a Custom RCP Application

[cedric@xxxxxxxxxxx]

Tahnks for your quick reply Jody.
Still investigating...
My goal would be in integrate udig with BIRT charts in my own branded RCP
application.

I've also tried to base my product on plugins and included ALL plugin from
SDK RC13 and my distance tool plugin.

The run gives me the same kind of output :

I've included ALL udig features from SDK RC13 in my product. Don't know
which one include the help plugin...

>From the UDIGActionBarAdvisor :
line 165 is :
fillHelpMenu(helpMenu);
line 449 is :
IAction welcome = ActionFactory.INTRO.create(window);

That's my feedback. Don't expect to much cause I'm not an eclipse expert.
I'll get back to you if I find something else and will update the wiki if
I find a way to get it working.
