For a hierarchical project, the EXE file generated by "pyinstaller" does not start.
Hi all, I have a problem with "pyinstaller". When I compile a single Python file, an EXE file is created in the "dist" directory, with which I can start the program and the GUI appears after a few seconds. But when I try to compile my project with "pyinstaller Relais_LastDauerTester.py" and generate an EXE file from it, an ".exe" file is also created in the "dist" directory, but nothing happens when I run both .exe files from Windows Explorer with a double click or from the DOS shell by invoking it. The mouse pointer changes briefly to an hourglass and then back and nothing happens. The only difference between these two programs is that the first is just a single file and my project is structured hierarchically. I tried to demonstrate the structure of the project below with two "DIR" DOS commands. In PyCharm you only need to run the top file "Relais_LastDauerTester.py", so I used this file for "pyinstaller". But it looks like I have to give (I believe) an extra argument for a hierarchical project. I googled all weekend to find a workable solution. But all I found was for converting a ".py" file and not a project like mine. With some suggestions, I should add a "pause" or "input ()" command to the code to prevent the DOS shell from disappearing quickly, which is out of the question for me. Do you have any idea what it could be? I thank you in advance for any useful advice that could help me.

New overriden and generated QLineEdit class will not be placed on the MainWindow as expected
Hi all
Some days ago, I send a question to this community about a clickable QLineEdit.
After getting the Hint to use QMouseEvent, I've written the program which is
working almost good but with a small or perhaps big ugliness and that is:
Below is the imgur link to the screenshots of my program after clicking the
buttons in sequence:
https://imgur.com/a/rfcP3qB
As you will see in the code blow, I override the QlineEdit widget and define a
new class " CustomLineEdit " to generate a "clicked" signal, when the user
pressed with mouse on this field.
I use this "CustomLineEdit" class and place it on the MainWindow with the
desired "layout".
I couldn't figure out, why this widget is placed not in the MainWindow, but
outside this window, as you can see in the top picture of the attached
screenshots.
When I take the line 12 (self.show()) from the code, the generated class will
not appear.
The problem here is that at the beginning, the MainWindow with a LineEdit field
should appear at the program start.
Then, after clicking on this field, the keypad should come up outside the
MainWindow.
Could anyone see, where my mistake is?
Thanks for any help.

Open a new window by mouse clicking in the QLineEdit field and not by clicking of a button
Hi all,
I'm looking for an approach, but couldn't find any appropriate answer to my
problem:
On my GUI on a tablet, I have bunch of QlineEdit widgets for the settings of my
task.
Because we have no keyboard connected to the tablet, I have put two buttons
("+" and "-") around each QLineEdit widget to increase or decrease its value.
When the target value is far away from the displayed one in the QLineEdit, I
have to click lots of times to reach the end value.
Due to this ugliness feature, I wanted to offer to the user the possibility to
click in the edit field to get another window with a numeric keypad to type the
target value. And then by clicking an OK button, the new window will be closed
and the typed value will be taken into the QLineEdit widget of my original GUI.
In all my searches, I found examples to open new windows by clicking a button
and not by clicking in an edit field.
I used the following line to have an edit field on window1.
self.text_from_window2 = QLineEdit('Setting Value')
And wanted to open another window (window2) in which I programmed a numeric
keypad. By typing the desired value on this keypad and enter OK, this value
should be taken to the edit field of window1.
But the following line brings an error that QLineEdit has no attribute
"clicked".
self.text_from_window2.clicked().connect(self.show_keypad_window)
I tried to use other attributes like focus, textChanged or textEdited. None of
them could help me.
Is it at all possible to use QLineEdit with mouse click to generate an action
(open new window)?
Has anyone an example of such a code snippet?
I am very curious to see if someone has a solution to my problem.
Regards
Mohsen

Hi
I tried to use your suggestion in my code, to see changes in the
background-color of the widgets (buttons and labels).
Below is the link of two screenshots of my GUI:
https://imgur.com/a/5LIefN7
They show the start phase and after clicking the “All Active” button.
As I wrote before, I use Stylesheets for configuring widgets.
Here is the code snipped of the relevant part:
::
if state == 'All Active':
. . .
. . .
for i in range(7):
for j in range(6):
self.buttons_active[j].setText('Inactive')
self.buttons_active[j].setEnabled(True)
self.buttons_active[j].setChecked(True)
self.buttons_active[j].setStyleSheet(css_pushButton())
##
self.buttons_reset[j].setChecked(True)
self.buttons_reset[j].setEnabled(False)
self.buttons_reset[j].setStyleSheet(css_pushButton())
#
if i > 0 and j < 6:
self.labels[i, j].setProperty('orange', True)
# self.labels[i, j].repaint()
# = 4
else:
self.labels[i, j].setProperty('yellow', True)
# self.labels[i, j].repaint()
# = 4
self.labels[i, j].setStyleSheet(css_Label())
self.labels[i, j].repaint()
aaa = 4
#
else:
. . .
. . .
for i in range(7):
for j in range(6):
self.buttons_active[j].setText('Active')
self.buttons_active[j].setEnabled(True)
self.buttons_active[j].setStyleSheet(css_pushButton())
##
##
self.buttons_reset[j].setChecked(False)
self.buttons_reset[j].setEnabled(True)
self.buttons_reset[j].setStyleSheet(css_pushButton())
##
if i > 0:
##
self.labels[i, j].setProperty('gray', True)
# self.labels[i, j].repaint()
# = 4
else:
self.labels[i, j].setProperty('yellow', True)
# self.labels[i, j].repaint()
# = 4
self.labels[i, j].setStyleSheet(css_Label())
self.labels[i, j].repaint()
aaa = 4
::
As you can see, the if-else part has to change the background-color of the gray
labels (at the start) and the buttons “Active”, “Reset”, “All Active” and
“Exit” to orange.
The problem is, after clicking on the “All Active” button all “Resets” and the
gray labels change their background-color to orange as desired.
But when I afterwards click again on this button (Now its name is “All

Flush / update GUIs in PyQt5 during debugging in PyCharm
Hi Guys I've written a GUI using PyQt5 and in there I use StyleSheets (css) for the buttons and labels to change their background- and foreground-colors and their states as well. Because my program doesn't function correctly, I try to debug it in my IDE (PyCharm). The problem is that during debugging, when I change some attributes of a button or label, let say its background-color, I can not see this modification of the color until the whole method or function is completed. I believe that I have seen somewhere during my searches and googling that one can flush or update the GUI after each step/action is done. But until now I couldn't manage it and I don't know where I have to invoke flush/update command in PyCharm. If anyone has done this before and knows about it, I would very appreciate seeing his solution. Regards Mohsen -- https://mail.python.org/mailman/listinfo/python-list
When should I use "parent=None" in __ini__ and "parent" in super()
Hi Guys I'm writing since almost one-year codes in Python, using TKinter and PyQt5. I'm somehow able to writes GUIs in both of them. But since I'm using more Pyqt5 and using classes with initialization and super() constructs, and also I saw lots of videos and examples of coding them, I still don’t know exactly how and when should I use the parent in __init()__ and super() construct. For example, the following lines use "parent=None" in the __init__ construct and "parent" in the super() construct. And sometimes I do not see any of them in these two constructs. class MyClass1(QWidget): def __init__(self, name, parent=None): super(MyClass1, self).__init__(parent) print(self.parent().test) And sometimes without "parent" like the following: class MyClass2(QWidget): def __init__(self, name): super(MyClass2, self).__init__() print(self.parent().test) Could anyone explain this to me when and for which action I have to use the first one "MyClass1" and when the second one "MyClass2"?

Thanks, for your answer. But, what is "imgur"? I'm not so familiar with handling of pictures in this group. How can I call "imgur" or how can I get there?

Free OCR package in Python and selecting appropriate widget for the GUI
Hi Guys Long time ago I've written a program in Malab a GUI for solving Sudoku puzzles, which worked not so bad. Now I try to write this GUI with Python with PyQt5 or TKinter. First question is: Is there any free OCR software, packages or code in Python, which I can use to recognize the given digits and their positions in the puzzle square. Second: Because, I can not attach a picture to this post, I try to describe my picture of my GUI. It is a 3x3 block / matrix (one third of the whole Sudoku 9x9 block). This block must be placed three times in row and columns. Each square of this 3x3 block has 3x3 digits from 1 to 9 at the initialization time. These digits are spread out in 3x3 equal distances. These are small fonts and black. The values given by the puzzle are red big fonts and not changeable The digits typed by the user are black big fonts and changeable If there is a big font from the Puzzle / User, these must be removed from the neighboring fields from the 3x3 matrix (1-9). Now my question is, actually a hint from your side: What should I take as widget for one of these small squares to have different content as I described above? I thought of a QLineEdit in PyQt5 or LineEdit in TKinter, because the user must type some values in there and therefore can not be labels. So again, for the sake of the clarity. • When the fields are empty, each square has to show digits from 1 to 9 with small fonts in 3x3 matrix order. • Given values in the puzzle are big fonts and red. • Digits which are typed by the user are big fonts and black. Now the question is, can I take only one LineEdit for all these tree situations, or I have to implement 9 small squares for small fonts and a big one for the big fonts? Any help and suggestion is welcome and appreciated. Best regards Mohsen -- https://mail.python.org/mailman/listinfo/python-list

That's true. I had a project which used Qt4.7, and I have still on my laptop. I have not so big knowledge about compiling and building stuff, so I have to get rid of 3.10 version.

Hi guys, I have on my laptop the python installation 3.8 and newly I installed newest version 3.10 as well on my laptop. Now I have two IDLEs for both of the installations.

Hello Alan,
I'm so happy that you have so good explained to me, what I have to do.
Now, it is a bit clearer how I can use the variables or references in another
modules.
I try to follow your suggestions to see if I can solve my problem.
Again thank you very much.

Hi Alan G,
Thanks a lot for giving me this solution.
Because I'm a newbie in Python and write programs since a couple of months, and
I'm not so familiar with classes, would be very nice to give me a code, how I
have to change my code into a class form.
I tried without a class and I ran into problems that the defined frame and
entry are not defined.

How to access a variable from one tab in another tab of a notebook?
Hi guys
I have written a GUI with two tabs, Tab 1 and Tab 2 as shown below:
On Tab 2 should be my settings parameters placed like "Val".
If the user types a value greater than 5 in the entry field, the background
color of Tab1 should be changed from light green to gray and the button "B1"
should be disabled
The problem is that I can't use the variable "val" from Tab2 in Tab 1, even if
I have defined in every function and file as the global. It brought all the
times the error message "val is not defined in Tab 1".
You can run the top level "TabTop" to see my GUIs and uncomment the if part in
Tab1 to see the error message.
Any help is really appreciated
Regards
Mohsen
# Filename: Tab1.py
from tkinter import *
def gen_t1(frame):
f = LabelFrame(frame, text='f', bg='lightgreen')
f.pack(expand=True, fill='both')
b1 = Button(f, text='B1').pack()
## if val > 5:
##f_enabled = 'disabled'
##f['bg'] = 'lightgray'
## else:
##f_enabled = 'normal'
##f['bg'] = 'lightgreen'
