I believe you will only want to reparent the main window. The button window will just be hidden until brought forward.
Or that's what I would try.

Hmmm, not having any luck. Can you take a peek at the python file and see if you spot anything? As it stands now the screen comes up blank.
Thanks

While I could not get the separate file thing to work I did get this to work all in one file and figured out how to call the dialog from each entry and put the number into the calling entry.

One of the things that bugged me was to have so many functions... one for each button etc. But that is not needed... (slap to forehead). The widget is passed when you press a button or most anything else so just use that to know which widget you just got the signal from. For example I can have 25 data entry fields with unique names and I only need one function to use the keypad thingy with.
This is so much better than what I was trying to do before making a function for each key. Some keys with different actions will still have a separate function.
Onwards and forward... next I think is to create a subroutine tab and sort out how to send the generated file to LinuxCNC via the python interface program_open().

def on_entry_button_press_event(self, widget, data=None):
self.current_entry = widget
self.response = self.dialog1.run()
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)
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()This is so much better than what I was trying to do before making a function for each key. Some keys with different actions will still have a separate function.

So thinking out loud here if you had a generic python code to handle everything normally done and used a standard naming convention then non-programmers could design the GUI and if they followed the naming conventions it would just work!
What do you guys think?
Edit: how would you handle status information with a scheme like this?

Naming conventions for callback signals in glade helps other programmers.
The trick is trying not to reference widgets directly from the base program.
Try to always use the widget object that is passed to you in the callback.
(This is what you discovered above)
It would be so nice if its easier to add subroutines!

I'm a little stuck, I've created a gui and some support files and have installed the py file to /usr/bin, the glade to /usr/share/linuxcnc and all that works fine. When I try and import a file with from gui7 import jog I get an error. I've copied the jog.py file to /usr/share/pyshared/gui7. The most frustrating thing is my gui6 import works...
Thanks

I need more info.
What is the error?
what is gui6 and gui7 file folders?
is the command?:
from gui7 import jog

gui7 is a copy of gui6
The command is
from gui7 import jog
The error is
Import Error: cannot import name jog
If I change the command to
from gui6 import jog
it works, so I've somehow missed a step and can't figure out what I missed.
From my working directory I do
sudo cp gui7 /usr/bin
sudo cp gui7.glade /usr/share/linuxcnc
sudo cp jog.py /usr/share/pyshared/gui7
Thanks

Turns out I needed to have a file __init__.py that I don't fully understand what that does as well as a symlink...
