OK, so that's theme-specific.
Some color names might be available regardless of theme, but I don't
know which ones; for example Gtk.InfoBar documentation explicitly
mentions {info,warning,question,other}_{bg,fg}_color.
I get the same (0,0,0,0) from get_background_color with your test
script. I've ran into this issue before and I have just used those
Adwaita names and a not-well-thought-out fallback if the lookup fails.
Curiously, if I swap the text view in your script for an entry, I get
the actual background color (white). In any reasonable theme, these
should probably both use the "base" color.

For Adwaita, you can find the available color names in gtk-main.css [1],
but I really don't know if they work across different themes.

I am under XFCE / GTK2 theme, so there is no such file in my theme. My
gtkrc file has a base[NORMAL] = "#ff" line, but I don't know how to
get that with gtk3. It should be possible as it's correctly rendered.
style.lookup_color("theme_base_color") returns a 0, 0, 0, 0 color here.

Hi,
I'm trying to get the default / current background color of a textview.
The code I do it:
context = tv.get_style_context()

But that returns a fully transparent color (0,0,0,0)
If I first set a custom color with tv.override_background_color(), then
get_background_color() correctly works and returns the color I set.
So how can I get the current default color?
I still can't get it working with GTK-3.8.2 and python3-gi 3.8.3
Any idea?
Did you wait untill the treeview is realized?
treeview.connect('realize', get_bg_color)
def get_bg_color(widget):
style = widget.get_style_context()
bgcolor = style.get_background_color(Gtk.StateType.NORMAL)
print(bgcolor)
Yes treeview is realized for sure, this code happens in a callback when
I press a key.

Consider this (mind you this uses pygtk): No, this is done AFTER the widget is realized. It's done in a textbiffer 'changed' callback, a long time (several seconds) after widget is shown. Your code is what I used in pygtk, but I'm not able to find a working equivalent in pygobject. -- Yann ___ pygtk mailing list pygtk@daa.com.au http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://faq.pygtk.org/
Re: [pygtk] [GTK3] get background color
Sounds like you're trying to retrieve the default colors before the widget
has been realized. Consider this (mind you this uses pygtk):
#!/usr/bin/env python
import gtk
def main():
window = gtk.Window(gtk.WINDOW_TOPLEVEL)
window.connect("delete-event", lambda *x: gtk.main_quit())
tv = gtk.TreeView()
tv.set_size_request(400, 250)
def realize(tv): print tv.get_style().bg[gtk.STATE_ACTIVE]
tv.connect("realize", realize)
realize(tv)
window.add(tv)
window.show_all()
gtk.main()
if __name__ == "__main__":
main()
The output of this example on my machine is
#dcdad5
#f0f0f0
which just goes to show that the colors before and after realization
(might) differ.
