gtk3

I've been taking a quick look at the GTK 3.10 documentation for a GtkStack. https://developer.gnome.org/gtk3/3.10/GtkStack.html It mentions that the child added to a GtkStack is given a property "icon-name". My question is - how can I change the value of this property. The reason - I want to change the GtkStackSwitcher button to be an icon not text but I want to code this - not use a GktBuilder UI. If you look at the gtk3-demo - Stack demo and the UI file you can see the GtkSwitcher has an icon. <?xml version="1.0" encoding="UTF-8"?> <interface> <!-- interface-requires gtk+ 3.6 --> <object

What is the best way to set background color for one entry and set it back to the default color? My script is now working but I am very sure this is not the best way. Also I still have two problems: If I insert a text, not containing string "red" or "green" and select this text I cant see my selection because It is all white. I think there are better ways then the way I insert self.entry_default_background_color_str into the CSS text. import gi gi.require_version('Gtk', '3.0') from gi.repository import Gtk from gi.repository import Gdk class Window(Gtk.Window): def __init__(self): self.screen

python 3.2.2 gtk3 3.2.2 python-gobject 3.0.2 I'm trying to display a GUI and do some work in the background. As I understand it should look something like this: #!/usr/bin/env python3 # -*- coding: utf-8 -*- import time from threading import Thread from gi.repository import Gtk, Gdk class Gui(): def run(self): self.Window = Gtk.Window() self.Window.set_border_width(8) self.Window.set_title("Некий GUI") self.Window.connect('destroy', lambda x: self.stop()) self.outBut = Gtk.Button.new_from_stock(Gtk.STOCK_OK) self.outBut.set_size_request(150, 35) self.outBut.connect('clicked', lambda x: self

I'm trying to convert the menubar in my Gtk app so it will use GActions (from the Gio) as opposed of GtkActions in Python3 using GObject Instrospection. I've been trying to figure it out on my own but so far it seems awfully complicated and I didn't have much luck with it. If someone could please post an example of how to create a simple menu GAction based with A submenu A menu item with a stock ID icon / hotkey A menu item with a non-stock icon / hotkey A checked menu item And radio menu item group A disabled(grayed out) menu item It would really help me a lot. EDIT : This is the menubar I

I'm a Vala/Gtk newbie and I'm trying to change the font size of a Gtk.Label, but I can't find a good way to do it. I find out that I can use the markup like this : var welcome_message = new Gtk.Label ("<span size='17000'>Hello</span>"); welcome_message.set_use_markup (true); But it seems a little hackish. What is the right way to do it ? You could try with css, I think lately this is the preferred way. Give your label a class, then load a css. If you are going to change the font size of a label, I bet you are also going to customize other things so the css may be useful for you. Thanks
