Hi,
I'm trying to get the default / current background color of a textview.
The code I do it:
context = tv.get_style_context()
color = context.get_background_color(Gtk.StateFlags.NORMAL)
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.
Here is a very simple scrpit that shows the problem. For me it prints:
<Gdk.Color(red=0.000000, green=0.000000, blue=0.000000, alpha=0.000000)>

from gi.repository import Gtk
def on_button_clicked(button, tv):
style = tv.get_style_context()
bgcolor = style.get_background_color(Gtk.StateType.NORMAL)
print(bgcolor)
win = Gtk.Window()
vb = Gtk.VBox()
tv = Gtk.TextView()
vb.add(tv)
button = Gtk.Button('get bg')
vb.add(button)
button.connect('clicked', on_button_clicked, tv)
win.add(vb)
win.show_all()
win.connect('delete-event', Gtk.main_quit)
Gtk.main()
