PyQt - Signals & Slots - Unlike a console mode application, which is executed in a sequential manner, a GUI based application is event driven. Functions or methods are executed in respo. Qt is well known for its signals and slots mechanism. But how does it work? In this blog post, we will explore the internals of QObject and QMetaObject and discover how signals and slot work under the hood. In this blog article, I show portions of Qt5 code, sometimes edited for formatting and brevity.

So I use QT Designer for the User Interface (UI), and convert this to python using “pyuic5” which generates a ui.py file
As this file gets overwritten every-time I make any changes to the UI, I would like to to have another .py file which has a signal/slot class and I can program there without any worries about copy/paste issues to/from the auto-generated ui.py file.

But how do I:

1. generate a signal from another class in another file ?
2. generate a slot from another class in another file ?
3. write back into the ui.py class, ie writing some text in a text field.

It is no problem doing the above if I keep all the code in the ui.py file, but it does become a copy/paste issue and prone to me making simple errors.

Any suggestions or is this really not doable.
I have searched the net a lot but nothing has come up and everything I have tried doesn't work

Thanks

I'm trying to use the auto generated code from QT designer and converting it to py code with pyuic5. Works fine so far as I get the py code to display the ui file just fine.

I'm trying to get a signal from a button. I have created an Action in the Action editor called 'actionOn_click'

This is the auto generated code for the button:

only 4 options are available instead of .trigger from within the QT designer. hover(), toggle() and deleteLater().

Am I doing this correctly ? I have the ui.py code as a separate file as it gets overwritten every-time I make some changes to the user interface (which is quite often)

I have spent hours trawling the net but all the info seems to be either that everything is handwritten from the start or the examples just connect a signal to a slot already within the QT frame work.

Any suggestions ?
