Problem: Unable to get the grey out effect on the dialog box. Following is the code:
Have tried to place the dialogBox.setGlassEnabled(true); before show/center and after show/center also. And Have searched every where on Google and tried to achieve it in every possible way, but no luck.
Create a new project from scratch. Take out everything else and put them in your onModuleLoad(). Let us know if you see the glass panel
If yes, run your existing code and inspect the dialog styling. Most probably you have overriden the glass style somewhere
