DESCRIPTION
       The QRadioButton widget provides a radio button with a text or pixmap label.

       QRadioButton and QCheckBox are both option buttons. 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 QButtonGroup.

       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 QPushButton, 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().

MEMBER FUNCTION DOCUMENTATION
QRadioButton::QRadioButton ( QWidget * parent, const char * name = 0 )
       Constructs a radio button with no text.

       The parent and name arguments are sent on to the QWidget constructor.

QRadioButton::QRadioButton ( const QString & text, QWidget * parent, const char * name = 0 )
       Constructs a radio button with the text text.

       The parent and name arguments are sent on to the QWidget constructor.

QKeySequence QButton::accel () const
       Returns the accelerator associated with the button. See the "accel" property for details.

bool QButton::autoRepeat () const
       Returns TRUE if autoRepeat is enabled; otherwise returns FALSE. See the "autoRepeat"
       property for details.

void QButton::clicked () [signal]
       This signal is emitted when the button is activated (i.e. first pressed down and then
       released when the mouse cursor is inside the button), when the accelerator key is typed or
       when animateClick() is called. This signal is not emitted if you call setDown().

       The QButtonGroup::clicked() signal does the same job, if you want to connect several
       buttons to the same slot.

       Warning: Don't launch a model dialog in response to this signal for a button that has
       autoRepeat turned on.

       See also pressed(), released(), toggled(), autoRepeat, and down.

       Examples:

QButtonGroup * QButton::group () const
       Returns the group that this button belongs to.

       If the button is not a member of any QButtonGroup, this function returns 0.

       See also QButtonGroup.

bool QRadioButton::isChecked () const
       Returns TRUE if the radio button is checked; otherwise returns FALSE. See the "checked"
       property for details.

bool QButton::isDown () const
       Returns TRUE if the button is pressed; otherwise returns FALSE. See the "down" property
       for details.

bool QButton::isExclusiveToggle () const
       Returns TRUE if the button is an exclusive toggle; otherwise returns FALSE. See the
       "exclusiveToggle" property for details.

bool QButton::isOn () const
       Returns TRUE if the button is toggled; otherwise returns FALSE. See the "on" property for
       details.

bool QButton::isToggleButton () const
       Returns TRUE if the button is a toggle button; otherwise returns FALSE. See the
       "toggleButton" property for details.

const QPixmap * QButton::pixmap () const
       Returns the pixmap shown on the button. See the "pixmap" property for details.

void QButton::pressed () [signal]
       This signal is emitted when the button is pressed down.

       See also released() and clicked().

       Examples:

void QButton::released () [signal]
       This signal is emitted when the button is released.

       See also pressed(), clicked(), and toggled().

void QButton::setAccel ( const QKeySequence & ) [virtual]
       Sets the accelerator associated with the button. See the "accel" property for details.

void QButton::setAutoRepeat ( bool ) [virtual]
       Sets whether autoRepeat is enabled. See the "autoRepeat" property for details.

void QRadioButton::setChecked ( bool check ) [virtual slot]
       Sets whether the radio button is checked to check. See the "checked" property for details.

void QButton::setDown ( bool ) [virtual]
       Sets whether the button is pressed. See the "down" property for details.

void QButton::setPixmap ( const QPixmap & ) [virtual]
       Sets the pixmap shown on the button. See the "pixmap" property for details.

void QButton::setText ( const QString & ) [virtual]
       Sets the text shown on the button. See the "text" property for details.

ToggleState QButton::state () const
       Returns the state of the toggle button. See the "toggleState" property for details.

void QButton::stateChanged ( int state ) [signal]
       This signal is emitted whenever a toggle button changes state. state is On if the button
       is on, NoChange if it is in the" no change" state or Off if the button is off.

       This may be the result of a user action, toggle() slot activation, setState(), or because
       setOn() was called.

       See also clicked() and QButton::ToggleState.

QString QButton::text () const
       Returns the text shown on the button. See the "text" property for details.

void QButton::toggle () [slot]
       Toggles the state of a toggle button.

       See also on, setOn(), toggled(), and toggleButton.

void QButton::toggled ( bool on ) [signal]
       This signal is emitted whenever a toggle button changes status. on is TRUE if the button
       is on, or FALSE if the button is off.

       This may be the result of a user action, toggle() slot activation, or because setOn() was
       called.

       See also clicked().

       Example: listbox/listbox.cpp.

   Property Documentation
QKeySequence accel
       This property holds the accelerator associated with the button.

       This property is 0 if there is no accelerator set. If you set this property to 0 then any
       current accelerator is removed.

       Set this property's value with setAccel() and get this property's value with accel().

bool autoMask
       This property holds whether the radio button is automatically masked.

       See also QWidget::autoMask.

bool autoRepeat
       This property holds whether autoRepeat is enabled.

       If autoRepeat is enabled then the clicked() signal is emitted at regular intervals if the
       button is down. This property has no effect on toggle buttons. autoRepeat is off by
       default.

       Set this property's value with setAutoRepeat() and get this property's value with
       autoRepeat().

bool checked
       This property holds whether the radio button is checked.

       This property will not effect any other radio buttons unless they have been placed in the
       same QButtonGroup. The default value is FALSE (unchecked).

       Set this property's value with setChecked() and get this property's value with
       isChecked().

QPixmap pixmap
       This property holds the pixmap shown on the button.

       If the pixmap is monochrome (i.e. it is a QBitmap or its depth is 1) and it does not have
       a mask, this property will set the pixmap to be its own mask. The purpose of this is to
       draw transparent bitmaps which are important for toggle buttons, for example.

       pixmap() returns 0 if no pixmap was set.

       Set this property's value with setPixmap() and get this property's value with pixmap().

QString text
       This property holds the text shown on the button.

       This property will return a QString::null if the button has no text. If the text has an
       ampersand (&) in it, then an accelerator is automatically created for it using the
       character that follows the '&' as the accelerator key. Any previous accelerator will be
       overwritten, or cleared if no accelerator is defined by the text.

       There is no default text.

       Set this property's value with setText() and get this property's value with text().
