gtk3 active tab styling

[Fabien Meghazi (OpenERP)]

I can't style the active tabs of terminator with gtk3's gtk.css

this css declaration:

tab {
    background-color: red;
}

... works (all tabs are red).
But this one...

tab:active {
    background-color: red;
}

... will not change the color of the active tab.
I also tried with :selected but it does not work either.

What am I missing ?

A little bit of patience :-) (only joking :-)

I say that because we're doing a bunch of work in this bug
https://bugs.launchpad.net/terminator/+bug/1599453
and this branch
https://code.launchpad.net/~stephen-j-boddy/terminator/gtk3-fix-transparency
to fix transparency. As a result I've had to get pretty gnarly with the CSS styling to fix various problems. I've also cloned the gnome-terminal stylings used under Ambiance for fancy tabs.

Terminator should be using the normal styling for the tabs, and indeed, when I use
GTK_DEBUG=interactive terminator
with either the branch before, or after the current work, I get red active tabs by copying and pasting your tab:active snippet. See attached screenshot.

Beyond that I can't say.

Thanks Stephen !

Also I see in the later bug report that you suggest to run terminator with

GTK_DEBUG=interactive terminator

I already tried that before posting and couldn't get the debugger on terminator.

If I use another gtk3 program, let's say GTK_DEBUG=interactive galculator then I can see the debugger window.

Any idea if terminator need particular settings in order to get this gtk inspector ?

The only thing that occurs to me off the top of my head is that you have gtk2 terminator installed, and are running/testing gtk3 terminator from a local path. The command above would search the PATH, finding the gtk2 version, which wouldn't work. You would need to give a relative path (i.e. ./terminator for the current directory) to the gtk3 terminator. That's about the only suggestion I have. Otherwise, it should just work.

No, I only have terminator 1.90 installed from the Kali rolling distro based on debian testing and I can tell to the look of the tabs and preference window that it's gtk3. Besides I used strace to ensure it was reading my gtk-3/gtk.css. But that's not a big deal, I'll just wait the bug lp:1599453 to be closed. Thanks !

Fabien, have you tested the gtk3 head lately? Is it working for you now? If you read through the changes made for lp:1599453 you should see how you can create a css overrides file in your ~/.local/share/themes folder to change aspects of Terminators styling, along with quite a few examples. Please let me know if I can close this bug now.
