That is, they - can be switched on (checked) or off (unchecked). The classes - differ in how the choices for the user are restricted. Check boxes - define "many of many" choices, whereas radio buttons provide a - "one of many" choice. In a group of radio buttons only one radio - button at a time can be checked; if the user selects another - button, the previously selected button is switched off. - - The easiest way to implement a "one of many" choice is simply to - put the radio buttons into TQButtonGroup. - - Whenever a button is switched on or off it emits the signal - toggled(). Connect to this signal if you want to trigger an action - each time the button changes state. Otherwise, use isChecked() to - see if a particular button is selected. - - Just like TQPushButton, a radio button can display text or a - pixmap. The text can be set in the constructor or with setText(); - the pixmap is set with setPixmap(). - - <img src=qradiobt-m.png> <img src=qradiobt-w.png> - - \important text, setText, text, pixmap, setPixmap, accel, setAccel, isToggleButton, setDown, isDown, isOn, state, autoRepeat, isExclusiveToggle, group, setAutoRepeat, toggle, pressed, released, clicked, toggled, state stateChanged - - \sa TQPushButton TQToolButton - \link guibooks.html#fowler GUI Design Handbook: Radio Button\endlink -*/ - -/*! - \property TQRadioButton::checked \brief Whether the radio button is - checked - - This property will not effect any other radio buttons unless they - have been placed in the same TQButtonGroup.
