Gtk3 - Python - Glade - 'Linked' comboboxes on different windows - python

I have two Gtk.Comboboxes on a main window :
the first, has its own Gtk.Liststore
the second one, linked to a Gtk.TreeModelFilter which is linked to a second Gtk.Liststore
When I select a value in the first one, the second one displays values according to my selection. This works well in the main window.
But in my application, I need to use this comboboxes combination many times, and when I use it on another window, this generates a Gtk Error that I don't understand:
"Gtk-CRITICAL **: 00:27:38.289:
gtk_tree_model_filter_set_visible_func: assertion
'filter->priv->visible_method_set == FALSE' failed"
Could someone explain me what's wrong with my code and what is the meaning of that error message?
Here is the glade file (test.ui)

Thank you in advance.

The problem was due to the fact that the second combobox on the main window and the second combobox on 'other' window were using the same filter.
I've created another filter and the second comboboxes have now their own filter linked to a common Gtk.Liststore.
Everything works fine, now.

I have developed a simple glade form that I mean to manipulate with python-3.10.
I thought I had the code right, but the controls just do not respond. (in particular, the buttons).
If anyone can help, I would be much obliged. I thought the "connect_symbols(self)" in the main Gui class would have taken care of it, but I'm still missing something.
Here is the program:
#!/usr/bin/env python
import gi
gi.require_version('Gtk', '3.0')
from gi.repository import Gtk
import sys
import os
builder = Gtk.Builder()
class GUI:
def __init__ (self):
builder.add_from_file('Form-10a.glade')
builder.connect_signals(self)
self.Pindir = None
self.Poutdir = None
self.Psortby = 'type'
self.Preport = 'False'
self.Pverbose = 'True'
window = builder.get_object('window1')
window.show_all()
#
def onSubmitButtonCli#cked(self, button):
inputdir = builder.get_object('inputdir').get_property('text')
print(f'inputdir = {inputdir}')
tv = os.path.exists(inputdir)
if (tv == False):
print(inputdir, "is not a vaild directory, try again.")
else:
self.Pindir = inputdir
outputdir = builder.get_object('outputdir').get_property('text')
print(f'outputdir = {outputdir}')
self.Poutdir=outputdir
name_button = builder.get_object('NameButton')
#print('[NameButton] active:', name_button.get_active())
#print('[NameButton] group :', name_button.get_group())
for item in name_button.get_group():
name = item.get_name()
truth_value = item.get_active()
print(name, '=', truth_value)
if (truth_value == True):
self.Psortby = name
i = self.Psortby.index('Button')
self.Psortby=self.Psortby[0:i]
report_button = builder.get_object('ReportY')
for item in report_button.get_group():
name = item.get_name()
truth_value = item.get_active()
print(name, '=' , truth_value)
self.Preport = truth_value
verbose_button = builder.get_object('VerboseY')
for item in verbose_button.get_group():
name = item.get_name()
truth_value = item.get_active()
print(name, '=', truth_value)
# tv = ((truth_value=='True')?1:0)
self.Pverbose = truth_value
with open('scripts-search.conf','w') as w:
w.write('[Main]\n')
outputdata = 'inputdir: ' + self.Pindir + '\n'
w.write(outputdata)
outputdata = 'outputdir: ' + self.Poutdir + '\n'
w.write(outputdata)
outputdata = 'sortby: ' + str(self.Psortby) + '\n'
w.write(outputdata)
outputdata = 'report: ' +str(self.Preport) + '\n'
w.write(outputdata)
outputdata = 'verbose: ' + str(self.Pverbose) + '\n'
w.write(outputdata)
w.write('\n')
Gtk.main_quit()
def onDestroy(self,menuitem):
Gtk.main_quit()
def onQuitButtonClicked(self,button):
Gtk.main_quit()
def main():
while True:
try:
app = GUI()
Gtk.main()
except Exception as e:
print ("Error!!")
print (e.inst)
Gtk.main_quit()
if __name__ == '__main__':
rv = 0
rv = main()
sys.exit(rv)
And, if anyone is interested, here is Form-10a.glade:

I am a bit rusty with Python, but when I tried out your code and glade file, I got a different behavior. Whenever I clicked on buttons or tried to close down the application, new windows kept spawning. I had to manually kill the application. The small revision I did to get things to work was to simplify the main block by removing the "while True:" test.
def main():
try:
app = GUI()
Gtk.main()
except Exception as e:
print ("Error!!")
print (e.inst)
Gtk.main_quit()
After that, the "Submit" button produced output and the "Quit Without Saving" button worked. I noticed in your glade file that you had no signal set up yet for the "Save" button.
Hope that helps.
Regards.

Note: I unfortunately use Google translate for translation. Please ignore my mistakes.
Hello there. I'm trying to develop an application with PyGTK. I am using Glade as UI designer. But unfortunately when I try to start my application I get an error like this.

Libhandy needs to be initialized before it can be recognized in UI files. Try adding Handy.init() in your main file.

I recently made a code in python3.x and for the interface I used a .glade file but when I run the code the interpreter returns to me the error "AttributeError: Handler Gtk_main_quit not found" and so on for all other functions of the code.
Python code:

self.window = builder.get_object("window1")
# Obtendo o widget text_entry (a área de texto do nosso programa) pois
# iremos utiliza-la nas funções de inversão da URL e para adicionar o a
# URL já invertida
self.text_area = builder.get_object("text_entry")
# Obtendo o widget about_dialog (janelinha com as informações do programa)
self.about = builder.get_object("about_dialog")
#Exibe a janela do programa
self.window.show_all()
builder.connect_signals({"gtk_main_quit": Gtk.main_quit,

This answer is pretty easy. You have a signal called Gtk_main_quit in the Glade file but are looking for a signal of gtk_main_quit in your .py file. And it seems most of the other strings are mismatched too. Always watch your cases when dealing with strings.

i want to handle the menu click event but,
this missing handler warning is occuring,
where i am wrong?
im connecting the signal ab with handler abcd
on menuitem6, on activate event,
is it correct for handling a click event?
here is the error:
abc.py:15: RuntimeWarning: missing handler 'a
bc'
builder.connect_signals({ "on_window_destroy" : gtk.main_quit })

here's the code :

You can use builder.connect_signals(self). Then you just have to make methods that are named like the handler in your xml file. So in this case:
class TutorialApp(object):
def __init__(self):
builder = gtk.Builder()
builder.add_from_file('./tutorial.xml')
builder.connect_signals(self)
self.window = builder.get_object('disasm')
##rest of you __init__
def abc(self, menuitem):
print "tst"
def on_window_destroy(self, window):
gtk.main_quit()

As a newbee I am trying to create a basic theme installer using Glade and python. Everything is working fine but i am not able to find anywhere how to use get_filename() method for gtkFileChooserButton.
My Glade File Looks Like this.

`
And Python Code is:
import sys
try:
import pygtk
pygtk.require("2.0")
except:
pass
try:
import gtk
except:
print("GTK Not Availible")
sys.exit(1)
class workplz(object):
def __init__( self ):
builder = gtk.Builder()
builder.add_from_file("heme.glade")
builder.connect_signals({"on_main_destroy" : self.quit, "on_Add_clicked" : self.add, "on_Quit_clicked" : self.quit})
self._window = builder.get_object("main")
self._window.show()
def add(self, widget):
target=DD.get_filename()
print target
def quit(self, widget):
sys.exit(0)
if __name__ == "__main__":
wine = workplz()
gtk.main()
what is the right way of doing it???

I believe if you would get your GtkFileChooserButton object from the builder and save a reference to it as a member of workplz class you could query it in the add signal handler. See if script below would work for you:
class workplz(object):
def __init__( self ):
builder = gtk.Builder()
builder.add_from_file("heme.glade")
builder.connect_signals({"on_main_destroy" : self.quit, "on_Add_clicked" : self.add, "on_Quit_clicked" : self.quit})
# get GtkFileChooserButton object
self.DD = builder.get_object('DD')
self._window = builder.get_object("main")
self._window.show()
def add(self, widget):
target = self.DD.get_filename()
print target
def quit(self, widget):
sys.exit(0)
hope this helps, regards
