SWT：在运行时更改 Shell 的样式

Question

Is there a way to change the style of a Shell at runtime?

I would like to have a shell not resizable but capable to fill, with its content, the whole screen, when it's in fullscreen. Is there a way to accomplish that?

In other words, when a Shell is not resizable and it has for example a Background Image I get this in full screen :

On the other hand when the Shell is resizable and I go in full screen I get this:

So would like to obtain the second effect but with a not resizable Shell.

Any help would be appreciated.

Following Stefan's comment, I was able to do it listening to the resize event and checking the fullscreen flag, resizing appropriately the shell's size to the monitor size when it's in full screen and to normal size when is not. Here the code that does the trick:

shell.addListener(SWT.Resize, new Listener() {
            @Override
            public void handleEvent(Event arg0) {
                if (shell.getFullScreen()) {
                    Rectangle r = getMonitorSize(shell);
                    shell.setSize(r.width, r.height);
                    shell.redraw();
                } else {
                    shell.setSize(WINDOW_WIDTH, WINDOW_HEIGHT);
                    shell.redraw();
                }
            }
        });
