List of all member functions. The QButton class is the abstract base class of button widgets, providing functionality common to buttons. The QButton class implements an abstract button, and lets subclasses specify how to reply to user actions and how to draw the button. QButton provides both push and toggle buttons. The QRadioButton and QCheckBox classes provide only toggle buttons, QPushButton and QToolButton provide both toggle and push buttons.
Any button can have either a text or pixmap label.
When the user clicks a toggle button to toggle it on, the button is first pressed, then released into on state. This is useful mostly for pixmap buttons since they have no automatic accelerator. See also QButtonGroup . This enum defines the state of a toggle button at any moment. Toggle - pressing the button toggles it between an On and and Off state.
