Description Curtis d'Entremont CLA 2005-03-29 12:34:21 EST 
I'm using some non-editable Combos with a list of pre-set strings to select 
from, and I want it to stretch to accomodate the longest string inside the 
list. This works fine except when I switch to a certain font in Japanese - MS 
UI Gothic. And it doesn't seem to be a Japanese thing, if I use another font, 
it works. It seems to be computing the size incorrectly. I've noticed this in 
our UI, and I can also find some instances in some preference pages where they 
do the same thing. See screenshots to follow.

Can you confirm that this is still failing in the 3.1 stream?  I seem to 
remember fixing something in this area.
Comment 3 Steve Northover CLA 2005-03-29 20:22:23 EST 
Better, can you provide a snippet that fails under 3.0.1?  Thanks.
Comment 4 Curtis d'Entremont CLA 2005-03-29 22:17:25 EST 
Try the following, it will work fine, but switch to MS UI Gothic font (you 
might have to install some asian language packs), and the last a is partially 
truncated. I also tried using m5a, and got the same result.

---------

import org.eclipse.swt.SWT;
import org.eclipse.swt.layout.GridLayout;
import org.eclipse.swt.widgets.Combo;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;

public class Test {

public static void main (String [] args) {
	Display display = new Display ();
	Shell shell = new Shell(display);
	shell.setLayout(new GridLayout());
	
	Combo c = new Combo(shell, SWT.READ_ONLY);
	c.add("aaa");
	c.select(0);
	
	shell.open ();
	while (!shell.isDisposed ()) {
		if (!display.readAndDispatch ()) display.sleep ();
	}
	display.dispose ();
}
}
