From Eclipse corner.
	Summary: The preference dialog should have a maximum size so it will never be bigger then the display.


I have opened a problem report with your comment about a maximum size for the dialog. I agree the it should never get bigger then your display.

As a workaround, you can use getControl() and get/set its bounds if the size is too big. There is API in Display to get the display bounds so you can compare the dialog bounds with the display.

But I have to say that I agree with Randy and about the size of the preferences dialog. It should not be made too big and I think 70% is too big. If you have a text that needs a big area to be shown, if may be a good idea rethink about your page as Randy suggested.

Hope it helps.
Eduardo.
