You can import into eclispe to observe source code. Or you put plugin into eclispe drop folder to reproduct this bug.

Comment 3 Remy Suen CLA 2010-08-30 07:01:10 EDT
So this is only a problem on Macs with the Carbon build? It cannot be reproduced on other platforms? Is there a problem on 3.6 with Cocoa?

CN test as a workspace project

Oleg, could you please try the test with this project on your mac in 3.6 and 3.4.2 and see if you can reproduce it?

Using Eclipse 3.6 I can reproduce it on Carbon; it works fine on Cocoa 32bit. Seems like a painting issue.
Comment 6 Felipe Heidrich CLA 2010-08-30 15:52:36 EDT
works for me on snow leopard running eclipse 3.7
I'll try on the leopard now,

can anyone post a screenshot of the problem ? I'm not sure what I'm looking for on the top left corner.

This is using Eclipse SDK 3.6 / Carbon, on Mac OS X 10.5.8 (Leopard, I believe.)
Comment 8 Felipe Heidrich CLA 2010-08-30 16:32:25 EDT
I can see the problem on 1.5.8

Comment 10 Felipe Heidrich CLA 2010-08-30 17:25:15 EDT
Simple SWT snippet that reproduces the problem:

import org.eclipse.swt.layout.*;
import org.eclipse.swt.widgets.*;
import org.eclipse.swt.*;


public class PR323943 {
public static void main(String[] args) {
	Display display = new Display();
	Shell shell = new Shell(display);
	shell.setLayout(new FillLayout(SWT.VERTICAL));
	
	
	Composite comp = new Composite(shell, SWT.NONE);

	final Composite comp1 = new Composite(shell, SWT.NONE);
	comp.addListener(SWT.MouseDown, new Listener() {
		public void handleEvent(Event event) {
			comp1.dispose();
		}
	});
	comp1.setLayout(new FillLayout());
	Text text = new Text(comp1, 0);
	text.setText("Textlength Textlength Textlength Textlength Textlength ");
	Combo combo = new Combo(comp1, SWT.DROP_DOWN);
	combo.add("AI Bayan");
	combo.add("Combolength Combolength Combolength Combolength Combolength Combolength Combolength Combolength Combolength Combolength Combolength");
	combo.select(1);

	shell.pack();
	shell.open();
	while (!shell.isDisposed()) {
		if (!display.readAndDispatch())
			display.sleep();
	}
	display.dispose();
}
}

second patch

I am not able to reproduce this new problem (not sure what step I am missing). Please could you try this new patch and see if both problems are fixed for you? This patch fixes the first problem in a simpler and more reliable way. I suspect it will fix the second problem as well.

Note that the second patch has to applied on top of the first patch.
