Pseudo-states
Each widget can have some pseudo-states, such as hover, pressed, and more. They can be selected in style sheets using the : operator, as seen in the following example:
QRadioButton:!hover { color: black }
Just like with sub-controls, always refer to Qt Style Sheets Reference in the Qt Creator Help mode for a list of applicable pseudo-states for each widget.
