How to change the style of the main application window shell [message #1219476]

Hello,

I am migrating my application from eclipse 3.x to eclipse 4.3 and I want to set the style of the main application window i.e. the shell that is created in application MTrimmedWindow in e4.

Earlier we were doing it using

IWorkbenchWindowConfigurer configurer = getWindowConfigurer();
configurer.setInitialSize(new Point(0, 0));
configurer.setShowCoolBar(false);
configurer.setShowStatusLine(false);
configurer.setShellStyle(SWT.DIALOG_TRIM | SWT.RESIZE);

But now in e4 application after reading some forum replies I got to know that custom renderer needs to be created for that.
I created my own renderer extending WBWRenderer and as I wanted to change the style of shell I am overriding createWidget method.
Now the problem is that if I am just creating a new shell in this createWidget method then it is not working. Might be because this method has a lot of other code also.
So I copied all this code into my overridden method of createWidget & just changed the style of shell according to my need. Then this worked but for this I have to put some private methods also into my custom renderer class from WBWRenderer.
SO my question is to confirm that if I am doing it in a right way?
or is there any other mechanism to do this in a more efficient way?

Thanks

A bit late, but still: I had the same problem in 4.3 - I also saw no other choice but to extend the WBWRenderer. In 4.4 it is possible to adapt the shell style by doing someting along these lines (at least working in my case):

MWindow window = /*get window model*/
window.getPersistedState().put(IPresentationEngine.STYLE_OVERRIDE_KEY, String.valueOf(SWT.TOOL));

This can now be solved with a specific "persisted state" key flag, as documented in https://bugs.eclipse.org/bugs/show_bug.cgi?id=386951 . For example to realize a NO_TRIM window, add the key/value styleOverride/8, where 8 is the value if you get the numeric of

int val = SWT.NO_TRIM;
System.out.println(val);
