When running this code:
import tkinter as tk
class MyApplication(tk.Tk):
def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
self.title('Programma')
self.geometry('500x400')
self.button = tk.Button(self, text='Execute', command=self.fun)
self.button.grid(row=0, column=4, stick=tk.W)
def fun(self):
print('Hello')
app = MyApplication()
app.mainloop()
I get the following error:
Traceback (most recent call last): File "C:/Users/Andrea/Desktop/hfhfhg.py", line 17, in <module>
app = MyApplication() File "C:/Users/Andrea/Desktop/hfhfhg.py", line 10, in __init__
self.button = tk.Button(self, text='Execute', command=self.fun) File "C:\WPy64-3910\python-3.9.1.amd64\lib\tkinter\__init__.py", line 2346, in __getattr__
return getattr(self.tk, attr) AttributeError: '_tkinter.tkapp' object has no attribute 'fun'
I understand that the code is not optimal for a GUI but I would like to understand how Tkinter works without using a frame object. Please can you help me?

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 have tried first my mapview function with only the mapview in the build which worked, but I had to return in the build mapview. Then I tried having the mapview on my first screen, and I face problems with it:

A couple notes about errors encountered in your original code:
When you use bind or on_press (or any event binding) you should bind to a method. If you bind to something like self.utw(), you are executing the self.utw() method and trying to bind to whatever that method returns. You should bind to the method, not its return, like this: self.message.bind(width=self.utw).
In a Label, the font size is set using font_size not fontsize.
In the above code, MapsPage is a Screen that contains a GridLayout. That GridLayout contains a MapView and a Button.
The AboutPage is also a Screen, and it contains a GridLayout that contains a Label.
The build() method is simplified, since both MapsPage and AboutPage are Screens, there is no need to create additional Screens just to contain them.
The error message in your post is caused by the self.pressbutton() call in the __init__() method of MapsPage.
Sorry for the long post but wished to give as much as poss
There is a lot of code not shown here but I'm trying to clean up a huge function of buttons in a PyQt5 Gui
I have a GUI output and all is working well and I'm now making an attempt to remove the repeated code and so creating a function to create the buttons.
In a functioned name initUI I have around 20 buttons. As can be seen from the code, the old way was creating each one separately.
What I have done is to create a function that the parameters are sent to and this then creates them.
This does work apart from defRun arg sent to button.
This is passing a call to another function I've highlighted with >>>>arg<<<< this isn't really in the code
class iac2tf(QMainWindow):
def __init__(self):
super(iac2tf, self).__init__()
self.initUI()
self.setGeometry(0, 0, 1700, 1000)........
def button (self, buttonName, buttonText, >>>>defRun<<<<, buttonWidth, buttonHeight, buttonx, buttony):
self.buttonName = QtWidgets.QPushButton(buttonText,self)
>>>>self.buttonName.clicked.connect(lambda:self.defRun)<<<<
self.buttonName.resize(buttonWidth,buttonHeight)
self.buttonName.move(buttonx,buttony)
self.buttonName.show()
def initUI(self):
#passed style
self.openFilebutton = self.button('openFile', 'Open File', >>>'open()'<<<< ,110,30,5,50)
#Old style
self.ProcessFile = QtWidgets.QPushButton('Process File',self)
self.ProcessFile.clicked.connect(self.processFile)
self.ProcessFile.resize(110,30)
self.ProcessFile.move(5, 80)

options |= QFileDialog.DontUseNativeDialog

passing to a local to func var all of above but is as is :(
Here is an example of passing functions as arguments.
class Template(QWidget):
def __init__(self):
super().__init__()
self.vbox = QVBoxLayout(self)
self.create_button('Open', self.open)
self.create_button('Close', self.close)
def create_button(self, text, slot):
btn = QPushButton(text)
btn.clicked.connect(slot)
self.vbox.addWidget(btn)
def open(self):
QFileDialog.getOpenFileName(self)
Also worth noting that the arg buttonName is never actually used in this function:
def button (self, buttonName, buttonText, >>>>defRun<<<<, buttonWidth, buttonHeight, buttonx, buttony):
self.buttonName = QtWidgets.QPushButton(buttonText,self)
. . .
That variable only exists in the local scope of the function, and self.buttonName refers to another object entirely. That is to say, if you wanted to refer to a button you created where you passed 'openFile' for the buttonName arg, it would not be called self.openFile, it would be called literally self.buttonName. You could however, use exec() to achieve this, although it is generally discouraged.
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:

def on_button_clicked(self, widget):

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.
