Newbie Glade user confounded by radio buttons
Question
I have a Glade GTK Gui which is meant to be a Front End for a CLI program I wrote a couple of years ago.
There are a number of fields for the user to fill in. These will be theoretically processed when the user presses "Submit", like in HTML. (Otherwise, they could press "Quit Without Saving")
I can actually glean the GtkEntry fields and use their content. But I am fuddled with the radio buttons. In the GUI, I can't seem to press the button at all, and I have no idea how to get the content they are meant to convey.
I am including a program that is designed to do little more than show the GUI and try to test its features.
I am including this program and the glade file in its XML form.
#!/usr/bin/env python
import gi
gi.require_version('Gtk', '3.0')
from gi.repository import Gtk
import sys
builder = Gtk.Builder()
class GUI:
def __init__ (self):
builder.add_from_file('EntryForm.glade')
builder.connect_signals(self)
window = builder.get_object("window1")
window.show_all()
def onSubmitButton(self, button):
idir = builder.get_object('inputdir')
result = idir.get_property('text')
print(f'inputdir = {result}')
odir = builder.get_object("outputdir")
result2 = odir.get_property("text")
print(f'outputdir = {result2}')
builder.get_objects()
builder.get_object('radiobuttons')
x = radiobuttons.get_label()
print (f'radiobutton select is {x}')
def onDestroy(self, menuitem):
Gtk.main_quit()
def on_window1_destroy(self, window): # close window with 0 or X
Gtk.main_quit()
def main():
app = GUI()
Gtk.main()
if __name__ == "__main__":
sys.exit(main())
and, as promised, the.glade file.

I don't expect anyone to pore over the source code, but I would at least appreciate some pointers on radio buttons, particularly how to obtain their contents.
Thanks,

In .glade you define RadioButton with id="NameButton" so you need
name_button = builder.get_object('NameButton')
print( name_button.get_active() )
But problem is that every RadioButton is treated as separated group and when group has only one button then it is always True .
Buttons should be in groups. Second and third RadioButton should have property group with ID of first RadioButton
<property name="group">NameButton</property>
like
<child>
<object class="GtkRadioButton" id="NameButton">
# ...
</object>
</child>
<child>
<object class="GtkRadioButton" id="SizeButton">
# ...
<property name="group">NameButton</property>
</object>
</child>
<child>
<object class="GtkRadioButton" id="TypeButton">
# ...
<property name="group">NameButton</property>
</object>
</child>
So you have to change code in XML.
Full working code with changes in .py and .glade
