DESCRIPTION
       The QCheckBox widget provides a checkbox with a text label.

       QCheckBox and QRadioButton 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. Radio buttons define a "one of many" choice, whereas checkboxes provide" many
       of many" choices.

       A QButtonGroup can be used to group check buttons visually.

       Whenever a checkbox is checked or cleared it emits the signal toggled(). Connect to this
       signal if you want to trigger an action each time the checkbox changes state. You can use
       isChecked() to query whether or not a checkbox is checked.

       Warning: The toggled() signal can not be trusted for tristate checkboxes.

       In addition to the usual checked and unchecked states, QCheckBox optionally provides a
       third state to indicate "no change". This is useful whenever you need to give the user the
       option of neither checking nor unchecking a checkbox. If you need this third state, enable
       it with setTristate() and use state() to query the current toggle state. When a tristate
       checkbox changes state, it emits the stateChanged() signal.

       Just like QPushButton, a checkbox 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
QCheckBox::QCheckBox ( QWidget * parent, const char * name = 0 )
       Constructs a checkbox with no text.

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

QCheckBox::QCheckBox ( const QString & text, QWidget * parent, const char * name = 0 )
       Constructs a checkbox with text text.

       The parent and name arguments are sent 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 QCheckBox::isChecked () const
       Returns TRUE if the checkbox 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.

bool QCheckBox::isTristate () const
       Returns TRUE if the checkbox is a tri-state checkbox; otherwise returns FALSE. See the
       "tristate" 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 QCheckBox::setChecked ( bool check ) [slot]
       Sets whether the checkbox 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 QCheckBox::setNoChange ()
       Sets the checkbox to the "no change" state.

       See also tristate.

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.

void QCheckBox::setTristate ( bool y = TRUE )
       Sets whether the checkbox is a tri-state checkbox to y. See the "tristate" 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 checkbox 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 checkbox is checked.

       The default is unchecked, i.e. FALSE.

       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().

bool tristate
       This property holds whether the checkbox is a tri-state checkbox.

       The default is two-state, i.e. tri-state is FALSE.

       Set this property's value with setTristate() and get this property's value with
       isTristate().
