Dear All:

I am using the following code, which seems to work on Linux amd64, but not on Windows (it works, but the window seems to get moved from the top-left corner).

Any ideas?

Is there a proper way to do this?

Thank you
Misha

	javascript.addListener(SWT.Modify,new Listener() {
		protected int lines=0;
		public void handleEvent(Event e) {
		    int newlines=javascript.getLineCount();
		    if (newlines>10) {
			newlines=10;
		    }
		    if (newlines!=lines) {
			lines=newlines;
			((GridData)javascript.getLayoutData()).heightHint=javascript.getLineCount()*javascript.getLineHeight();
			getShell().pack();
		    }
		}
	    });

I think you are on the right path. At the moment, I'm not sure of any
other ways of achieving this. However, the provided snippet does not
required to set heightHint as pack() takes care of computing and setting
the minimum size required for the text widget. So, the snippet can be
optimized to -

text.addListener(SWT.Modify,new Listener() {
protected int lines=0;
public void handleEvent(Event e) {
int newlines=text.getLineCount();
if (newlines>10) {
newlines=10;
} else if (newlines!=lines) {
lines=newlines;
text.getShell().pack();
}
}
});
