DESCRIPTION
       The QCheckListItem class provides checkable list view items.

       QCheckListItems are used in QListViews to provide QListViewItems that are checkboxes,
       radio buttons or controllers.

       Checkbox and controller check list items may be inserted at any level in a list view.
       Radio button check list items must be children of a controller check list item.

       The item can be checked or unchecked with setOn(). Its type can be retrieved with type()
       and its text retrieved with text().

   Member Type Documentation
QCheckListItem::ToggleState
       This enum specifies a QCheckListItem's toggle state.

       QCheckListItem::Off

       QCheckListItem::NoChange

       QCheckListItem::On

MEMBER FUNCTION DOCUMENTATION
QCheckListItem::QCheckListItem ( QCheckListItem * parent, const QString & text, Type tt =
       RadioButtonController )
       Constructs a checkable item with parent parent, text text and of type tt. Note that a
       RadioButton must be the child of a RadioButtonController, otherwise it will not toggle.

QCheckListItem::QCheckListItem ( QCheckListItem * parent, QListViewItem * after, const QString &
       text, Type tt = RadioButtonController )
       Constructs a checkable item with parent parent, which is after after in the parent's list
       of children, and with text text and of type tt. Note that a RadioButton must be the child
       of a RadioButtonController, otherwise it will not toggle.

QCheckListItem::QCheckListItem ( QListViewItem * parent, const QString & text, Type tt =
       RadioButtonController )
       Constructs a checkable item with parent parent, text text and of type tt. Note that this
       item must not be a RadioButton. Radio buttons must be children of a RadioButtonController.

QCheckListItem::QCheckListItem ( QListViewItem * parent, QListViewItem * after, const QString &
       text, Type tt = RadioButtonController )
       Constructs a checkable item with parent parent, which is after after in the parent's list
       of children, with text text and of type tt. Note that this item must not be a RadioButton.
       Radio buttons must be children of a RadioButtonController.

QCheckListItem::QCheckListItem ( QListView * parent, const QString & text, Type tt =
       RadioButtonController )
       Constructs a checkable item with parent parent, text text and of type tt. Note that tt
       must not be RadioButton. Radio buttons must be children of a RadioButtonController.

QCheckListItem::QCheckListItem ( QListView * parent, QListViewItem * after, const QString & text,
       Type tt = RadioButtonController )
       Constructs a checkable item with parent parent, which is after after in the parent's list
       of children, with text text and of type tt. Note that tt must not be RadioButton. Radio
       buttons must be children of a RadioButtonController.

QCheckListItem::QCheckListItem ( QListViewItem * parent, const QString & text, const QPixmap & p
       )
       Constructs a RadioButtonController item with parent parent, text text and pixmap p.

QCheckListItem::QCheckListItem ( QListView * parent, const QString & text, const QPixmap & p )
       Constructs a RadioButtonController item with parent parent, text text and pixmap p.

QCheckListItem::~QCheckListItem ()
       Destroys the item, and all its children to any depth, freeing up all allocated resources.

void QCheckListItem::activate () [virtual protected]
       Toggle check box or set radio button to on.

       Reimplemented from QListViewItem.

bool QCheckListItem::isOn () const
       Returns TRUE if the item is toggled on; otherwise returns FALSE.

bool QCheckListItem::isTristate () const
       Returns TRUE if the item is tristate; otherwise returns FALSE.

       See also setTristate().

void QCheckListItem::paintCell ( QPainter * p, const QColorGroup & cg, int column, int width, int
       align ) [virtual]
       Paints the item using the painter p and the color group cg. The item is in column column,
       has width width and has alignment align. (See Qt::AlignmentFlags for valid alignments.)

       Reimplemented from QListViewItem.

void QCheckListItem::paintFocus ( QPainter * p, const QColorGroup & cg, const QRect & r )
       [virtual]
       Draws the focus rectangle r using the color group cg on the painter p.

       Reimplemented from QListViewItem.

int QCheckListItem::rtti () const [virtual]
       Returns 1.

       Make your derived classes return their own values for rtti(), and you can distinguish
       between list view items. You should use values greater than 1000, to allow for extensions
       to this class.

       Reimplemented from QListViewItem.

void QCheckListItem::setOn ( bool b ) [virtual]
       Sets the button on if b is TRUE, otherwise sets it off. Maintains radio button
       exclusivity.

void QCheckListItem::setState ( ToggleState s )
       Sets the toggle state of the checklistitem to s. s can be Off, NoChange or On.

       Tristate can only be enabled for CheckBox or CheckBoxController, therefore the NoChange
       only applies to them.

       Setting the state to On or Off on a CheckBoxController will recursivly set the states of
       its children to the same state.

       Setting the state to NoChange on a CheckBoxController will make it recursivly recall the
       previous stored state of its children. If there was no previous stored state the children
       are all set to On.

void QCheckListItem::setTristate ( bool b )
       Sets tristate to b if the Type is either a CheckBoxController or a CheckBox.

       CheckBoxControllers are tristate by default.

       See also state() and isTristate().

ToggleState QCheckListItem::state () const
       Returns the state of the item.

       See also QCheckListItem::ToggleState.

void QCheckListItem::stateChange ( bool ) [virtual protected]
       This virtual function is called when the item changes its state. NoChange (if tristate is
       enabled and the type is either CheckBox or CheckBoxController) reports the same as Off, so
       use state() to determine if the state is actually Off or NoChange.

QString QCheckListItem::text () const
       Returns the item's text.

void QCheckListItem::turnOffChild () [protected]
       If this is a RadioButtonController that has RadioButton children, turn off the child that
       is on.

Type QCheckListItem::type () const
       Returns the type of this item.
