[Glade-users] number entry

[jthornton at gnipsel.com (John Thornton)]

Dave,

I apologize for not mentioning that I'm using Python... What I tried was
to make a main glade file and a keypad glade file and bring them both
into my python program with the builder but could not get the two
screens to show up correctly. Either the keypad screen would show up or
I got a blank screen.

So next I thought I would try making a dialog box and I was able to get
that working. In the process I discovered I had been doing some things
the long hand way like using a separate function for each number. What I
stumbled across was the widget is passed to the function so I could use
that to get the label of the button and know which entry had called the
keypad. Of course other keys like Clear and Save have their own
functions.

This function stores the widget that runs the dialog.
def on_entry_button_press_event(self, widget, data=None):
    self.current_entry = widget
    self.response = self.dialog1.run()

This function adds the number pressed to the keyboard label
def on_kb_clicked(self, widget, data=None):
  self.current = self.num_entry.get_text()
  self.current = self.current + widget.get_label()
  self.num_entry.set_text(self.current)

This function saves the numbers to the calling entry box and closes the dialog
def on_kb_save_clicked(self, widget, data=None):
  self.current_entry.set_text(self.num_entry.get_text())
  self.num_entry.set_text('')
  self.dialog1.hide()

All in all it works fine, but I was looking for a modular thing with the
keypad being in it's own glade file and being able to load it into
another file so to speak.

Thanks
John
