Dialog with a fixed size? [message #1511966]

Hello,

I successfully created a dialog with the E4 application model including a MPart but as I see its size can be changed by the user which is not what I need in this concrete case. How can I say that the size of the dialog should be immutable?

Thanks,
Guenther

I now answer to my own question as I found out how it goes:

I created a custom renderer by copying the WBWRenderer to a new class and let it extend SWTPartRenderer. I also had to add init(context) at the beginning of the init()-method so that the images could be found. Then I adapted the createWidget(MUIElement element, Object parent) method to my specific needs. Meaning that where the syle variables are set (in the else-branch) I exchanged

int style = SWT.TITLE | SWT.RESIZE | SWT.MAX | SWT.CLOSE | rtlStyle;

by

int style = SWT.TITLE | SWT.APPLICATION_MODAL | SWT.CLOSE | rtlStyle;

in order to make it a fixed-size and modal dialog.

To let the new renderer be called, I went to the dialog definition (NOT the part definition) in the Application model . In the dialog definition on the Supplementary page I added under "Persisted State":

Key: Custom Renderer
Value: bundleclass://<bundle>/<package. rendererclass>.

That's it.

Regards,
Günther
