How to get the background color of a widget in GTK and Python?

由 放肆的年华 提交于 2019-12-10 14:47:07
问题 I want to get the normal background color of a widget (a GtkHeaderBar , in this case). I'm currently using style = self.get_titlebar().get_style_context() to get the style, and color = style.get_property("background-color", Gtk.StateFlags.NORMAL) to get the background color associated to that style. However it returns a Gkd.RGBA object with the following properties: Gdk.RGBA(red=0.000000, green=0.000000, blue=0.000000, alpha=0.000000) But if I open GTK Inspector, select the HeaderBar, and

问题 I have a tray icon with a popup menu. I am trying to set the background color of the menu items in this popup. I am able to set the text color but not the background color of the menu item. The background that appears is the default Ubuntu orange, and I can't override it. I've created a sample application that demonstrates this problem. Just copy-paste it into a .py file and it should run. from gi.repository import Gtk, Gdk import sys class TrayIcon: def __init__(self): self.statusicon = Gtk

由 拥有回忆 提交于 2019-12-09 08:03:30
I am trying to draw a scatterplot with cairo in gtk3. To start, I am using the examples here: http://zetcode.com/tutorials/cairographicstutorial/ They compile with gtk2 successfully but display no image.

There is no member window exposed as part of GtkWidget

Learning GUI programming with GTK+2 or GTK+3?

由 牧云@^-^@ 提交于 2019-12-08 17:59:25
问题 I am new to GUI programming, and I haven't found yet what library is best for my purpose (i want to make desktop environment applications, eg. docks, panels, desklets etc.) I have started learning basics of GTK, mainly using PyGtk. Most tutorials i found on line are for GTK+2.0. Recently however, GTK+3 has been released. So i am a bit unsure as to what that means for my learning curve: Should i learn using GTK+3 and forget about GTK+2? Does using one or the other really makes a difference
