Get rid of CTabFolders min/max buttons artifacts [message #1701442]

Hi,

I managed to get rid of the minimize / maximize buttons either by CSS or by using a custom renderer. But: as soon as the CTabFolder's tabHeight is set to anything less than the optimal size or SWT.DEFAULT, the buttons are visible again although they are not working. Even with a tabHeight of 0 there are still artifacts visible from those buttons.
Is this a known bug or even already fixed? Is there a way to work around it?

Have you tried to remove the MinMaxAddon from your addons section in the application model?

The MinMaxAddon is not listed in my application model's addons, but is listed in my model spy - does the compatibility layer add it to the model?

Removing the addon at runtime also does not remove the buttons.

I also checked the CTabFolder's getMinimizeVisible at runtime when the buttons are visible and it is set to false.

also the setMinimizeVisible is never called with true if I remove the MinMaxAddon during startup.

This looks more and more like a bug to me...

Thank you for the link Dirk, based on this thread I got rid of the buttons in the first place.
I'm not sure if you got my problem right though: The buttons are gone as long as I do not manipulate the tabHeight of my CTabFolder, just like I want them to. But: as soon as I set the tabHeight lower than the default value I get the buttons without functionality: index.php/fa/22522/0/

Update: I finally found the reason: StackRenderer#adjustTopRight(...) manipulates the part's toolbar and for some reason it thinks it has to draw those items. After creating the widget I am able to set the ToolbarItems' exclude flags which finally removes those artifacts.

Still looks like a bug to me.

unfortunately I fail to see how Brian de Alwis wrote on Thu, 13 August 2015 18:36

See bug 426034.

relates to this. Yes, the bug reporter also wanted to get rid of the buttons but he did not have the problem with artefacts. With the CSS he mentioned I was able to hide the buttons but only as long as I do not touch my tabHeight.
