## Detailed Description

The QCheckListItem class implements checkable list view items.

There are three types of check list items: CheckBox, RadioButton and Controller.

Checkboxes may be inserted at top level in the list view. A radio button must be child of a controller.

## Member Function Documentation

### QCheckListItem::QCheckListItem ( QListView * parent, const char * text, Type tt = Controller )

Constructs a checkable item with parent parent, text text and type tt. Note that tt must not be RadioButton, if so it will not toggle.

### QCheckListItem::QCheckListItem ( QListView * parent, const char * text, const QPixmap & p )

Constructs a Controller item with parent parent, text text and pixmap p.

### QCheckListItem::QCheckListItem ( QListViewItem * parent, const char * text, const QPixmap & p )

Constructs a Controller item with parent parent, text text and pixmap p.

### QCheckListItem::QCheckListItem ( QCheckListItem * parent, const char * text, Type tt = Controller )

Constructs a checkable item with parent parent, text text and type tt. Note that a RadioButton must be child of a Controller, otherwise it will not toggle.

### void QCheckListItem::paintBranches ( QPainter * p, const QColorGroup & cg, int w, int, int h, GUIStyle ) `[virtual protected]`

Fills the rectangle. No decoration is drawn.

Reimplemented from QListViewItem.

### void QCheckListItem::paintCell ( QPainter * p, const QColorGroup & cg, int column, int width, int align ) `[virtual]`

Paints this item.

### void QCheckListItem::setOn ( bool b )

Sets this button on of b is TRUE, off otherwise. Maintains radiobutton exclusivity.

### void QCheckListItem::setup () `[virtual]`

Performs setup.

### void QCheckListItem::stateChange ( bool ) `[virtual protected]`

This virtual function is called when the item changes its on/off state.

### const char * QCheckListItem::text () const

Returns the text of this item.

### const char * QCheckListItem::text ( int n ) const `[virtual]`
