I'm writing a GTK+ app using embedded/extended Python3 as a scripting language. What I'd like do is make it possible for those scripts to include menus, but, so far, things aren't cooperating.
I do the usual python initialisation with:
PyImport_AppendInittab("gfig", &PyInit_gfig);
Py_SetProgramName (L"gfig");
Py_Initialize();
and then some setup with:
PyRun_SimpleString (
"import gfig\n"
"import sys\n" ........ )
(gfig is the app I'm writing, as well as the name of extension module.)
Then I run the app using
PyRun_File (fp, pyfile, Py_file_input, global_dict, local_dict);
to run the script:
from gi.repository import Gtk
class MyWindow(Gtk.Window):
def __init__(self):
Gtk.Window.__init__(self, title="Hello World")
self.button = Gtk.Button(label="Click Here")
self.button.connect("clicked", self.on_button_clicked)
self.add(self.button)
def on_button_clicked(self, widget):
print("Hello World")
win = MyWindow()
win.connect("delete-event", Gtk.main_quit)
win.show_all()
Gtk.main()
This results in:
[0] /mnt/disk5/personal/tinkering/gf3/src >./gf py4
Traceback (most recent call last): File "py4", line 3, in
from gi.repository import Gtk File "",

line 1523,in initialized, argv = Gtk.init_check(sys.argv)
AttributeError 'module' object has no attribute 'argv'
Here's the script:
from gi.repository import Gtk
class MyWindow(Gtk.Window):
def __init__(self):
Gtk.Window.__init__(self, title="Hello World")
self.button = Gtk.Button(label="Click Here")
self.button.connect("clicked", self.on_button_clicked)
self.add(self.button)
def on_button_clicked(self, widget):
print("Hello World")
win = MyWindow()
win.connect("delete-event", Gtk.main_quit)
win.show_all()
Gtk.main()
which works fine when from the command line:
[0] /mnt/disk5/personal/tinkering/gf3/src >python3 py4
I see that the script ends with "Gtk.main()" which, since I'm running python embedded under GTK+, looks like it may give me trouble in the future.
(I've tried Tk, wx, and, I think, Qt. None of them worked, but I didn't explore why not in any detail. I'd like to use Gtk.)
Any help greatly appreciated.

I'm trying to get a PyQt lineEdit widget to place its' contents within a variable in the module 'followup' but for some reason the module does not recognize the PyQt MainWindow as being properly instantiated.

I want to know how to fix it,cause i want to know logic behind it and use in popup() method.
Any help will be appriciated.
Thank You!
Maybe it's because popup creates a new Tk instance as self.app, but the style belongs to the first Tk instance created by root = Tk(). So a child of the second Tk instance cannot recognize it. Maybe you can try changing self.app = Tk() to self.app = Toplevel() to see if it works?
I am using windows 10 and anaconda3 to manage my python packages. This is my first time to use python, and I'm trying to make my own gui program with pyqt5. Also I'm trying to make .exe file using Pyinstaller. The issue I am running into is that the .exe is throwing the error block:

The same error occurs regardless of which .py file is used. For information, I wrote the used code below.
import sys
from PyQt5.QtWidgets import QApplication, QWidget, QPushButton, QVBoxLayout
class MyApp(QWidget):
def __init__(self):
super().__init__()
self.initUI()
def initUI(self):
btn1 = QPushButton('&Button1', self)
btn1.setCheckable(True)
btn1.toggle()
vbox = QVBoxLayout()
vbox.addWidget(btn1)
self.setLayout(vbox)
self.setWindowTitle('QPushButton')
self.setGeometry(300, 300, 300, 200)
self.show()

app = QApplication(sys.argv)
ex = MyApp()
sys.exit(app.exec_())
I uninstalled and reinstalled pyinstaller but it didn't work. I don't think its a code issue because the code is really simple. Can anyone give a solution or hint for this problem?
What happened for me is that the absolute path name had a space in it. Once the project was moved to a directory without spaces it was able to build
The solution of this problem is to use the full file name and append the flag -F to the file name. In your case for example if for the file App_ver05.py the absolute path is :
/home/user123/Desktop/foldername/App_ver05.py
Then use the command :
pyinstaller -F /home/user123/Desktop/foldername/App_ver05.py
I'm build application with pyobject (gtk) in Pydev , but i'm try to create a window
the following way:
Class Ventana

Gtk.Window.__init__(self,title=titulo )
self.connect("delete-event",Gtk.main_quit )
Class Aplicacion( Main):
def main():
win = Ventana()
if __name__ == '__main__':
main()
but I'm try to compile te App, show the following mistake:
Traceback (most recent call last):

Gtk = modules['Gtk']._introspection_module
KeyError: 'Gtk'
I'm try use the import
from gi.repository import Gtk
but, not works,because moudule not found.So i'm use the import:
from gi.overrides import Gtk
¿How to fix my trouble?
Sorry for my bad English
Thanks.
