Python pyqt5 reset all widget inputs

Question

I am using this method to have multiple windows GUI in a python script. With a button press, I open one of the two forms, that have multiple textEdits and comboBoxes, used to fill a word teamplate easier.

Now, I want to reset all the inputs after I finished filling the form, and save the document.

What behaviour I want:

From main window, open one of the forms depending on 2 ComboBoxes index (type of document, and the client's gender).

After I fill the form and exit it, I go back to the main window, and when I open again a form, the text edits are empty and the combo boxes are on index 0.

But i can't make it to work, either the inputs are not resetted, either I kill the popup window and the main window.

I can't only kill the popup, I can only hide it and show it again.

Answer 1

This is the code that make it work for me, I cant explain 100% why it works, but i think before I reloaded the same variable over and over, as now I am forcing it to reload the ui from the file containing it every time the variable is accesed.

For some reason, without the self in front of variable (on self.formWindow, in open function), the second window would just close a split second after it opened.

This works for me, I mostly understand the reason why is performing like this, but if someone can make things clear about the self part, I'm happy to learn.
