.SH DESCRIPTION
The QRadioButton widget provides a radio button with a text label.
.PP
QRadioButton and QCheckBox are both toggle buttons, that is, they can be switched on (checked) or off (unchecked). Unlike check boxes, radio buttons are normally organized in groups where only one radio button can be switched on at a time.
.PP
The QButtonGroup widget is very useful for defining groups of radio buttons.

.SH MEMBER FUNCTION DOCUMENTATION
.SH "QRadioButton::QRadioButton ( QWidget * parent, const char * name=0 )"
Constructs a radio button with no text.
.PP
The \fIparent\fR and \fIname\fR arguments are sent to the QWidget constructor.
.SH "QRadioButton::QRadioButton ( const QString & text, QWidget * parent, const char * name=0 )"
Constructs a radio button with a text.
.PP
The \fIparent\fR and \fIname\fR arguments are sent to the QWidget constructor.
.SH "void QRadioButton::drawButton ( QPainter * paint ) \fC[virtual protected]\fR"
Draws the radio button, but not the button label.
.PP
See also: drawButtonLabel().
.PP
Reimplemented from QButton.
.SH "void QRadioButton::drawButtonLabel ( QPainter * p ) \fC[virtual protected]\fR"
Draws the radio button label.
.PP
See also: drawButton().
.PP
Reimplemented from QButton.
.SH "void QRadioButton::focusInEvent ( QFocusEvent * e ) \fC[virtual protected]\fR"
Reimplemented for internal reasons; the API is not affected.
.PP
Reimplemented from QWidget.
.SH "bool QRadioButton::hitButton ( const QPoint & pos ) const \fC[virtual protected]\fR"
Reimplements QButton::hitButton(). This function is implemented to prevent a radio button that is on from being switched off.
.PP
Reimplemented from QButton.
.SH "bool QRadioButton::isChecked () const"
Returns TRUE if the radio button is checked, or FALSE if it is not checked.
.PP
See also: setChecked().
.SH "void QRadioButton::setChecked ( bool check ) \fC[virtual]\fR"
Checks the radio button if \fIcheck\fR is TRUE, or unchecks it if \fIcheck\fR is FALSE.
.PP
Calling this function does not affect other radio buttons unless a radio button group has been defined using the QButtonGroup widget.
.PP
See also: isChecked().
