Get variable name of Qt Widget (for use in Stylesheet)?

Question

In my application, a User clicks on any widget of my program (which are at the time; dormant) and picks a color for it.
This color will then be added to a stylesheet for

Answer 1

You need to first setObjectName("somename") before an object is named, then objectName() will work, or even better - findChild(), or findChildren()

Example

header:

QButton foo;

class:

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

Then, finally in your QSS..

#MySuperButton { 
     background: black;
}

This also works similarly to CSS with

QButton#MySuperButton {
     background: red;
}

The logic behind why you'd want to set multiple object names similarly (for different objects), or use the granularity of only one type of widget with a specific name is also pretty much the same as CSS.
