Created attachment 225547 [details] Sample code Create a ToolTip object, and set a very long text to its message. When we try to show this ToolTip, it takes a very long time. And during that time, there is no response for whole program. It seems to hang. But after tooltip finally shown, program will come back. I attached the sample code in attachement.
We put a fix for a similar problem (Bug 395464) but your example still fails with that change.
This is a bug in Window 7. Other applications also have this problem. Take a look at: http://social.msdn.microsoft.com/Forums/en-US/windowsuidevelopment/thread/a5a95763-9f10-4640-9d32-afd050a60bb3/ This patch works around the problem: http://git.eclipse.org/c/platform/eclipse.platform.swt.git/commit/?id=d3b70aad7149876ba42093794d2909bb52409b12
Created attachment 225910 [details] patch for 3.7.2 Note that this patch also includes the fix for bug#395464.
Hi Silenio, the hang issue has been resolved. But the patch has another problem. The tooltip will disappear quickly. You can reproduce this problem with our sample code. When you hover that button, you can see the tooltip quickly disappear. Could you help to take a look at it again? Thanks.

Steps I use: 1) Run app and window show near to the top left corner of the screen. 2) Move mouse over button and leave it stead. The tooltip appears with the tip pointing where the mouse is. The tooltip stays up for about 5 seconds and then fades away. Is there something different with your configuration or something missing on my steps?
Hi Silenio, is it possible there are another codes not included the patch for 3.7.2? On 2 Winodws 7, we can see the long tooltip quickly disappear. Not last for 1 second. If the tooltip is not so long, it won't quickly disappear. Also I tried the sample code on Windows XP without any patch, the long tool tip is also quickly disappear. You can try that.
What's your tooltip? Could you give us a screen shot for it? We set the tool tip as a very long text in the Sample code.
Created attachment 226112 [details] screenshot This is a the tooltip that shows for me running the attached Snippet. I cannot reproduce your problem on WinXp and Windows7 running 3.7.2 with the patch applied and latest code.
Hi Silenio, we just applied the patch for 3.7.2( https://bugs.eclipse.org/bugs/attachment.cgi?id=225910&action=diff). Is that correct? I found you also provided a git patch(http://git.eclipse.org/c/platform/eclipse.platform.swt.git/commit/?id=d3b70aad7149876ba42093794d2909bb52409b12). Which one is correct? Currently, we are using the patch for 3.7.2. Maybe the long tooltip disappear is caused by some different between our local changes and yours.

The patch from comment#3 is for the R3_7_maintenance branch. The patch for comment#2 was released into master. I was able to see the problem when I connected to your machine (Thanks). The problem happens in your machine because the tooltip is taller than the screen. This causes the tooltip to be display under the mouse pointer which triggers the underlying code that hides it. This is a bug in Window 7 itself. I will investigate whether we can work around it.
Hi Silenio, is there a possible available workaround in SWT Cocoa? Any updates about this bug? Thanks very much.
Sorry, I have not been able to find any work around.
