Get Qt Widget variable name (for use in stylish sheet)?

Question

In my application, the user clicks on any widget of my program (which is inactive at that time) and selects a color for it.
This color will be added to the stylesheet for this particular widget.

However, when the program ends and starts again, I would like this particular widget to retain its stylesheet.
I would like there to be no hard code in the style sheets for each widget. In fact, I would not even know which particular widget has a stylesheet.

I would really like for me to have one stylesheet for the application, as well as a new color code only for the selected widget.

(ie if the user clicked the QPushButton button and selects the style sheet {color: red},
I would like it to be just QPushButton, and no one else.
So, if this QPushButton has the variable name "Clicky",
in the QApplications stylesheet, I would add:
'QPushButton # Clicky {color: red}')

To do this and don’t need to hardcode it for each widget,
I have to somehow convert the variable name of my PyQt4 widgets to strings.
How can i do this?

Thanks!

(I read that getting python variable names from their values ​​is very difficult.
Is there any other form of identifier for the widget that can be added to the stylesheet?)

You need to first set the object_name ("somename") before the object name, then objectName () will work or even better - findChild () or findChildren ()

Example

Title:

QButton foo; 

Grade:

 foo = new QButton(); foo.setObjectName("MySuperButton"); 

Then finally in your QSS ..

 #MySuperButton { background: black; } 

It also works similarly to CSS with

 QButton#MySuperButton { background: red; } 

The logic is why you want to set multiple object names in the same way (for different objects) or use the granularity of only one type of widget with a specific name, also almost the same as CSS.
