I am using SWT to develop an application for windows. But I don't wan't the UI to be changed in diffrent operating systems. Is there any way to set a permanent Look and Feel for SWT, Also Is it possible to change the look and feel for SWT, such as jgoodies exist for Swings.
I don't want to use Swing, so don't advice me to switch to Swing.
As far as I know, the answer is no. At least not without a bunch of work. You see, the thing about SWT is that you are actually making calls to the OS to draw the widgets. So if you ask Windows to draw a button, you get a windows button. If you ask Linux to draw a button you get button from GTK, KDE/QT, or whatever windowing system is being used. OSX, same deal.
That being said...

If you are developing an application for windows why are you concerned about other operating systems?
