thanks. i can confirm the bug is gone.

i don't see any missing buttons, if you are talking about the buttons inside the table view, there are none: numberOfRowsInTableView return 0 in this sample. the 2 static buttons in the sample also display fine.

in my full application, the buttons in the table view display fine, and the background is transparent as it should be. good job.

This was a rather interesting bug report as the real problem was a whole layer below what at first seemed to be the issue.
It turned out that when I wrote the keyed decoding for NSColor I never had an example that showed colours that actually where non-opaque. For this reason the whole alpha handling was missing, but there were quite a few FIXMEs in the code saying so.

Your table views are now transparent as they should be, but also the buttons in them are missing, which seems to be a different issue :-(

attached is a sample project with a single window with table views.

the table views have "draw background" deselected in InterfaceBuilder, but gnustep draws the backgrounds nonetheless.
