.SH DESCRIPTION
The QCheckListItem class implements checkable list view items.
.PP
There are three types of check list items: CheckBox, RadioButton and Controller.
.PP
Checkboxes may be inserted at top level in the list view. A radio button must be child of a controller.
.SH MEMBER FUNCTION DOCUMENTATION
.SH "QCheckListItem::QCheckListItem ( QListView * parent, const QString & text, Type tt = Controller )"
Constructs a checkable item with parent \fIparent,\fR text \fItext\fR and type \fItt.\fR Note that \fItt\fR must not be RadioButton, if so it will not toggle.
.SH "QCheckListItem::QCheckListItem ( QListView * parent, const QString & text, const QPixmap & p )"
Constructs a Controller item with parent \fIparent,\fR text \fItext\fR and pixmap \fIp.\fR
.SH "QCheckListItem::QCheckListItem ( QListViewItem * parent, const QString & text, Type tt = Controller )"
Constructs a checkable item with parent \fIparent,\fR text \fItext\fR and type \fItt.\fR Note that this item must not be a a RadioButton. Radio buttons must be children on a Controller.
.SH "QCheckListItem::QCheckListItem ( QListViewItem * parent, const QString & text, const QPixmap & p )"
Constructs a Controller item with parent \fIparent,\fR text \fItext\fR and pixmap \fIp.\fR
.SH "QCheckListItem::QCheckListItem ( QCheckListItem * parent, const QString & text, Type tt = Controller )"
Constructs a checkable item with parent \fIparent,\fR text \fItext\fR and type \fItt.\fR Note that a RadioButton must be child of a Controller, otherwise it will not toggle.
.SH "void QCheckListItem::activate () \fC[virtual protected]\fR"
Toggle checkbox, or set radio button on.
.PP
Reimplemented from QListViewItem.
.SH "bool QCheckListItem::isOn () const"
Returns TRUE if this item is toggled on, FALSE otherwise.
.SH "void QCheckListItem::paintBranches ( QPainter * p, const QColorGroup & cg, int w, int, int h, GUIStyle ) \fC[virtual protected]\fR"
Fills the rectangle. No decoration is drawn.
.PP
Reimplemented from QListViewItem.
.SH "void QCheckListItem::paintCell ( QPainter * p, const QColorGroup & cg, int column, int width, int align ) \fC[virtual]\fR"
Paints this item.
.PP
Reimplemented from QListViewItem.
.SH "void QCheckListItem::paintFocus ( QPainter * p, const QColorGroup & cg, const QRect & r ) \fC[virtual]\fR"
Draws the focus rectangle.
.SH "void QCheckListItem::setOn ( bool b ) \fC[virtual]\fR"
Sets this button on if \fIb\fR is TRUE, off otherwise. Maintains radio button exclusivity.
.SH "void QCheckListItem::setup () \fC[virtual]\fR"
Performs setup.
.PP
Reimplemented from QListViewItem.
.SH "void QCheckListItem::stateChange ( bool ) \fC[virtual protected]\fR"
This virtual function is called when the item changes its on/off state.
.SH "QString QCheckListItem::text () const"
Returns the text of this item.
.SH "QString QCheckListItem::text ( int n ) const \fC[virtual]\fR"
Reimplemented for internal reasons; the API is not affected.
.PP
Reimplemented from QListViewItem.
.SH "void QCheckListItem::turnOffChild () \fC[protected]\fR"
If this is a Controller that has RadioButton children, turn off the
child that is on.
