you should connect function.
and you call other Form like this
if you want only once call Form, remove thread.

self.frame1(Dialog) # call this when the program start
self.frame2(Dialog) # call this after 3 second self.frame1(Dialog)
Any help would be appreciated ThankYou
That a code works does not imply that it is correct, for example I see that you have combined 2 codes generated by Qt Designer and obviously they are going to overlap, the correct thing is to have 2 windows that are exchanged as shown below using QTimer.

Very much a beginner on the UI side of things!
I'm trying to transfer a list from a dialog to the main window (when a button is pressed) and then transfer a new list back to the window when the dialog is accepted.
Here's a MWE of what I'm working on to give you an idea.
It should print out the following,
Desired output:
[b]
.
[b]
[a]
.
[a]
Achieved output:
[b]
.
[b]
[a]
.
[b]
Thanks in advance!

I have a list of data which is shown in the Qcombobox (using 'addItems')
Now - if the list is changed by loading data from a file with pushbutton - i don't see the new data in the combobx.

you only load the data to self.comboData but do not load them to self.comboBox.
At the end of
def load(self):
add the following lines:
self.comboBox.clear() # delete all items from comboBox
self.comboBox.addItems(self.comboData) # add the actual content of self.comboData
As the model used by QComboBox emits the dataChanged() signal whenever the data in an item are changed, the combobox is repainted automatically and it is not necessary to update the combobox by
self.comboBox.update()
When I press the button for go to a diferent page using setCurrentIndex I have problems with duplicate output values because if I set value "1" on QLineEdit on home_page for example and then go to conf_page and now I back to home_page, when I press the OK button for print content of QLineEdit for example, I get a duplicate output.
My code.

Add super(Form1, self).__init__() in __init__ method of Form1 class. Do the same for Form2
