Gtk.StyleContext.get_property doesn't set the red and green components when returning colors

Submitted by Robin Thompson

Description

The Gdk.RGBA returned Gtk.StyleContext.get_property always has the red and green components set to 0, whilst the blue and alpha components are returned correctly. This always occurs, regardless on the Gtk theme in use.

This bit of python demonstrates the problem:

#!/usr/bin/env python3

import gi gi.require_version("Gtk", "3.0") from gi.repository import Gtk, Gdk

class Testwin(Gtk.Window): def init(self):

    super().__init__(super().__init__(title="Theme color reader"))
    self.box = Gtk.VBox()
    self.label = Gtk.Label ("Test window")
    self.button = Gtk.Button("Button")
    self.entry = Gtk.Entry()
    self.mb = Gtk.MenuBar()

    self.box.add(self.mb)
    self.box.add(self.label)
    self.box.add(self.entry)
    self.box.add(self.button)

    self.add(self.box)

    self.set_size_request(300,100)
    self.connect("realize", self.realized_event)
    self.connect("delete-event", self.win_delete_event)

    self.show_all()

def win_delete_event(self, widget, event, data=None):
    Gtk.main_quit()

def get_col(self, widget):
    context = widget.get_style_context()
    state = context.get_state()

    print("state is %s" % state)
    bgcol = context.get_property("background-color", state)
    print("background color of %s is %s" % (widget.get_name(), bgcol))
    bcol = context.get_property("border-color", state)
    print("border color of %s is %s" % (widget.get_name(), bgcol,))

def realized_event(self, widget):
    self.get_col(self.mb)
    self.get_col(self.label)
    self.get_col(self.entry)
    self.get_col(self.button)

def main(): tw = Testwin() Gtk.main()

if name == "main": main()
