I want to add a border to a custom widget with style sheet, but the style sheet does not seem to work, anything wrong?
Firstly: add an actual widget to your example:
self.widget = QWidget(self)
layout = QVBoxLayout(self)
layout.addWidget(self.widget)
Secondly: do yourself a favour, and use triple-quotes:
self.widget.setStyleSheet("""
QWidget {
border: 20px solid black;
border-radius: 10px;
background-color: rgb(255, 255, 255);
}
""")
The dot-selector in your example is redundant. What it does is specify that only instances of QWidget
itself will be selected, as opposed to sub-classes of QWidget
. See the StyleSheet Syntax guide in the Qt docs.
