Hopefully this is quite simple, but I've only been using Python for three days so far...
Basically I have a class (Gui) that controls the gui, I also have another class, in a module called clipboards.py, that access the clipboard. I want to be able to update a GTKEntry box using a def in the gui class, but to do this, I have to create a new instance of the Gui class and so a new, identical copy, of the gui spawns.
Everytime the clipboard changes, I get a new icon in the notification area, linked to a new instance of the gui...
Perhaps there is something fundamentally wrong with the way I've coded this? I'd really like to keep things as separate as possible though.
The following is the main file I run to start the program:
#!/usr/bin/env python
import ui
import clipboards
if __name__ == '__main__':
startmonitoring = clipboards.linuxclipboard()
app = ui.Gui()
app.startgui()
This is ui.py:
#!/usr/bin/env python
import gtk
import config
class Gui(object):
#This bit fires up the GUI
def startgui(self):
try:
gtk.main()
except KeyboardInterrupt:
pass
#Code for quitting the program
def quit(self):
gtk.main_quit()
#Provides the necessary information for glade file and status icon locations
def __init__(self):
self.builder = gtk.Builder()
try:
gtk.destroy()
except:
print "nope"
self.builder.add_from_file("ViciousLex.glade")
self.builder.connect_signals(self)
#Set status icon
self.statusIcon = gtk.StatusIcon()
self.statusIcon.set_from_file("icons/lex14.png")
self.statusIcon.set_visible(True)
self.statusIcon.set_tooltip("Lex - A global dictionary")
#Connect status icon left click to activate dictionary window
self.statusIcon.connect("activate", self.activate_dictionary_window)
#Connect status icon right click to activate popup menu
self.statusIcon.connect("popup_menu", self.popup)
self.load_preferences()
#This code is used to toggle the visibility of any given window
def toggle_visibility(self, widget):
widget_name = self.builder.get_object(widget)
#Check whether window is currently invisible
if widget_name.get_property("visible") == 0:
#if so, show it

#if not, hide it
widget_name.hide()
