Why don't my form controls (Glade/Python) work? - python

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)

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.

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'm struggling with a GtkAssistant sidebar that is appearing automatically when I define a page title.
GtkAssistant does not accept Window Title. You need to define a Page Title but it enables that side bar.
I just want the Page Title. An example:
Considering this example, I would like to keep "Error Details" title but hide side bar. It is not useful for me. And there is no Gtk Doc mentions to remove that. Not sure if I can.

And the result is:
I would like to remove this weird side bar.

Question: How to disable GtkAssistant side bar with Page Title defined?
Using your glade.xml, i get the following error:
(Assistant.py:4515): Gtk-CRITICAL **: gtk_assistant_set_page_has_padding: assertion 'child != NULL' failed
and the Next Button keep stay insensitive.
Solved: Using assistant.set_page_complete(box, True) enables the Next Button.
However, using the following API Reference I get this result:
PyGObject API Reference:
Gtk.Assistant.signals.prepare
Gtk.Assistant.set_page_complete
Gtk.HeaderBar
Drawback:
The OS see the Gtk.Assistant. window title as undefined!
Using GtkAssistant.set_title(... has no result!
First add the signal "prepare" using Glade in GtkAssistant.
<signal name="prepare" handler="on_assistant_prepare" swapped="no"/>
Usage:
import gi
gi.require_version('Gtk', '3.0')
from gi.repository import Gtk
class GtkAssistant:
def __init__(self):
self.builder = Gtk.Builder()
self.builder.add_from_file(__file__.replace('.py', '.glade'))
self.builder.connect_signals(self)
assistant = self.builder.get_object("assistant")
# Preserve the page titels from glade
# Set page titles to empty '' to force not to show sidebar
for _id in ["page1", "page2", "page3"]:
box = self.builder.get_object(_id)
box.page_title = assistant.get_page_title(box)
assistant.set_page_title(box, '')
# Gtk.Assistant refuses to do .set_title even defined in glade
# <property name="title" translatable="yes">Registration-Assistant</property>
assistant.set_title('Registration-Assistant')
# Replace assistant.set_page_title(... with own function
assistant.set_page_title = self.set_page_title
# Replace the window decoration with a custom HeaderBar
self.title = Gtk.Label()
headerbar = Gtk.HeaderBar()
headerbar.set_show_close_button(True)
headerbar.set_custom_title(self.title)
assistant.set_titlebar(headerbar)
assistant.show_all()
def set_page_title(self, box, title):
self.title.set_text(title)
def on_assistant_prepare(self, assistant, box, user_data=None):
assistant.set_page_title(box, box.page_title)
# This will make update the buttons state
# to be able to continue the task.
assistant.set_page_complete(box, True)
def on_destroy(self, widget, data=None):
Gtk.main_quit()
if __name__ == '__main__':
assist = GtkAssistant()
Gtk.main()
Tested with Python: 3.5 - gi.__version__: 3.22.0 - Glade 3.20.0

I want to implement a Gtk.Menu that have horizontal menu items or buttons in it as in Google Chrome's menu how can I achieve this in GTK3?

This may not be exactly what you asked for, but it would be one way to do it.
Save this in a file and open it in glade to view the construction of the GUI.

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:
`import gi

#Obter a janela principal
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()
