Bug 24959 CoolBar with SWT.DROP_DOWN style
Run ControlExample on W2K. Also observed on WinXP. Go to Coolbar tab Set the DROP_DOWN style Move a coolitem so that it partially hides another coolitem containing the 'red circle' icon. The chevron appears normally indicating that the 'red circle' is partially obfuscated. - If the red circle is more than 80% covered, the chevron correctly expands to show the full red circle item. - If the red circle is slightly less covered (enough so that the chevron appears), the chevron can be clicked but does not expand to the full red circle item. This sounds like a bug to me. Is it the desired native widget behaviour?
