gitk looks ugly / doesn't honor theme settings

Question

I'm running Xubuntu, (actually linux mint with xfce on top, but I suppose it's essentially the same thing)

I set my appearance theme to (a modified version of) MurrinaStormCloud, but if I run gitk, it uses ugly font rendering, ugly colors, ugly widgets.

I think tcl is the thing to blame here, but can I fix it?

Here's a picture for comparison between what firefox looks like under the current theme and what gitk looks like:

Answer 1

gitk is implemented in tcl/tk. I've searched around but there doesn't seem to be much you can do; it is scolded as ugly on Linux everywhere. And apart from using a hideous toolkit, gitk has been growing worse for me as they put in more functions (mostly not used) the UI becomes even more confusing.

So I instead of a solution I recommend gitg, which is a similar tool, less mature, using GTK+.

Answer 2

Take a look at changing the default tk version.

Answer 3

To fix this the Debian (Ubuntu) way:

$ sudo apt-get install tk8.5
$ sudo update-alternatives --config wish

And then pick the wish8.5 alternative.

Answer 4

tcl/tk 8.5 is actually themeable and looks rather native on Windows 7 and apparently on Mac. Less care seems to have been given to write theme engine bridges for it under linux, but you can do two things:

• To get away from the "motif" look-and-feel to a slightly better one:

  $echo '*TkTheme: clam' | xrdb -merge -
  

To have it persist between reboots add the line *TkTheme: clam to ~/.Xresources, but I'm not sure if that's read whether you launch your desktop environment with startx or not.

• To get tk to use qt themes, you'll need to checkout and build tile-qt from: git://tktable.git.sourceforge.net/gitroot/tktable/tile-qt

Under Ubuntu 11.04 it was pretty easy:

$./configure --with-tcl=/usr/lib/tcl8.5/ --with-tk=/usr/lib/tk8.5/

$make

$sudo checkinstall

checkinstall being for creating a quick .deb instead of installing directly, keeps the system tidy.

Then afterwards as above, get tk to use your qt themes:

$echo '*TkTheme: tileqt' | xrdb -merge -

• There's also a tile-gtk in the same sourceforge repo as tile-qt, but it's thouroughly out-of date. I did manage to build it and install it after much fiddling but the visual results were messy - not recommended.

Answer 5

as kaizer.se said gitk (and also git gui) is implemented using tcl/tk, tk is the widget toolkit and do not care about gtk-based themes (or any at all afaik). And no this is not something you can fix (well rewriting gitk to use gtk widget's is ofc not impossible but hardly a 'fix') other than replacing it with something else.

You can change the font's in the preferences to make it slightly better, I use:
Main font: Helvetica 9
Diff display font: Courier 9
User interface font: Helvetica 9

This looks a little better and not as broken as the default's, well for me.
