Using Libglade with Python
| |
Using with python is an excellent option for rapid
prototyping and even build full strength applications. Like the use of
in C there is never any need for you to convert the
.glade file (containing the XML description of the interface)
into Python code. Instead, reads the XML and directly
builds the interface using the library (written in C but
with an interface for Python).
The basic code is:
#! /usr/bin/env python
import gtk
import libglade
import gnome.ui
def init_app ():
"Initialise the application."
global wTree
wTree = libglade.GladeXML ("gwords.glade", "app1")
dic = {"on_quit_button_clicked" : gtk.mainquit,
"on_exit1_activate" : gtk.mainquit}
wTree.signal_autoconnect (dic)
def main ():
init_app ()
gtk.mainloop ()
if __name__ == '__main__': main ()
|
Here we have linked the interface callback
on_exit1_activate to the library callback
gtk.mainquit. The on_exit1_activate is
associated through Glade with the Exit menu item and is supplied by
default by the Gnome Application Window.
Save this code into a file called gwords.py in your
/home/guest/Projects/gwords directory. Make the file executable
with chmod u+x gwords.py. Then run the program with
./gwords.py. Your interface should come to life.
Problems arise if you don't have the appropriate packages installed.
At a minimum make sure you have python-gnome
installed (this
package will depend on various other python and gnome packages which
should be automatically installed by choosing to install
python-gnome
if you are using Debian).
You may also need to ensure that the PYTHONPATH
environment variable includes the gnome and gtk modules, but check
this only if you have problems running your Python program.
