Using Glade with Python-Changing Widgets

[LaurelLynn]

Hi Boys,

I'm old to programming but new to Python. Since there are no fixed types or recasting, I can't figure out how my program can change widget properties in callbacks. For example, this is some of my basic Hello World Code:


class HellowWorldGTK:

def __init__(self):

#Set the Glade file
self.gladefile = "TopMa/topma.glade"
self.wTree = gtk.glade.XML(self.gladefile)

#Create our dictionay and connect it
dic = { "on_hiButton_clicked" : self.hi_clicked,
"on_MainWin_destroy" : gtk.main_quit }
self.wTree.signal_autoconnect(dic)

#callback for hi button
def hi_clicked(self, widget):
print "Top of the World Ma!!!"


The callback "hi_clicked" just prints the text to the command line, but what I want, is to change the button's label in the callback.

A GUI isn't very useful if I can't pass settings back and forth.

Can someone help a damsel in distress?

Ok, surely some expert will help you.

BTW next time, use CODE tags instead of INDENT. It will keep whitespace.






#callback for hi button
def hi_clicked(self, widget):
print "Top of the World Ma!!!"


The callback "hi_clicked" just prints the text to the command line, but what I want, is to change the button's label in the callback.


print just prints. I am no expert on Glade, but I would expect that you need to use some widget properties to change label.

self.something = "Top of the World Ma!!!" instead of print "Top of the World Ma!!!"

Thanks pmasiar,

I got it, actually it was:


widget.set_label( "Top of the World Ma!!!" )

I had tried that with self, and I guess I forget to try it with widget the first time around.
