command linetransparency
I am running Ubuntu 11.04 with gnome 2.3 and I would like my terminal window to be transparent.
The problems is the transparent settings in my terminal just shows the desktop background and not the actual windows that are opened behind the terminal. This works on my laptop where I have Xubuntu 11.10 and I see no reason why it should not work the same here.
This is how it should look:
This is how it looks:
I solved the problem, here's the code that works. The important part is setting the correct operator for operation that is being performed on the surface.
#!/usr/bin/env python
import cairo
from gi.repository import Gtk, Gdk
class MyWin (Gtk.Window):
def __init__(self):
super(MyWin, self).__init__()
self.set_position(Gtk.WindowPosition.CENTER)
self.set_border_width(30)
self.screen = self.get_screen()
self.visual = self.screen.get_rgba_visual()
if self.visual != None and self.screen.is_composited():
print "yay"
self.set_visual(self.visual)
box = Gtk.Box()
btn1 = Gtk.Button(label="foo")
box.add(btn1)
self.add(box)
self.set_app_paintable(True)
self.connect("draw", self.area_draw)
self.show_all()
def area_draw(self, widget, cr):
cr.set_source_rgba(.2, .2, .2, 0.9)
cr.set_operator(cairo.OPERATOR_SOURCE)
cr.paint()
cr.set_operator(cairo.OPERATOR_OVER)
MyWin()
Gtk.main()
or Guake terminal
