QDialog and Multithreading within PYQT5

[xtlc]

First: Thanks for your time. And thanks for the hint with processEvents. That worked! Here I think I was not clear enough in what I wanted to know:

Since you are adding the ui into your dialog class by composition (i.e. there is a "ui" member variable for the Ui_Dialog class), then you access the label as "self.ui.statusLabel".

I want to get ALL labels of the Ui_Dialog class - something like

Ui_Dialog.findChildren(QWidgets.QLabel)

Ui_Dialog.findChildren(QWidgets.QLabel)

To copy to clipboard, switch view to plain text mode 

if I wanted to find all QLabels ... but this only works for the resultWindow method. How does it work on the Ui_Dialog?

dir(Ui_Dialog)

dir(Ui_Dialog)

To copy to clipboard, switch view to plain text mode 

shows no method Children/findChildren.

The documentation for QObject::findChildren() says that the first argument should be a QString that names the type (ie. class) of the widgets you want to retrieve.

In C++, this is implemented using templates, as the documentation shows. I do not know how this is done in python.

In addition, you are using the name of your class (Ui_Dialog), not the name of the variable that implements that class in your dialog. So at a minimum, your code should look something like this:

self.ui.findChildren( QWidgets.QLabel )

self.ui.findChildren( QWidgets.QLabel )

To copy to clipboard, switch view to plain text mode 

assuming QWidgets.QLabel is the correct syntax for the argument. Perhaps it should be "QWidgets.QLabel" (ie. a quoted string) instead.

Or maybe you don't need the "ui" variable at all:

self.findChildren( QWidgets.QLabel )

self.findChildren( QWidgets.QLabel )

To copy to clipboard, switch view to plain text mode 

where "self" is your Dialog class instance.
