Detailed Description

+ + +The QListBoxItem class is the base class of all list box items. +

This class is an abstract base class used for all list box items. +If you need to insert customized items into a QListBox you must +inherit this class and reimplement paint(), height() and width(). +

See also QListBox. + +

Member Function Documentation

+

QListBoxItem::QListBoxItem ( QListBox * listbox = 0 ) +

+Constructs an empty list box item in the list box listbox. + +

QListBoxItem::QListBoxItem ( QListBox * listbox, QListBoxItem * after ) +

+Constructs an empty list box item in the list box listbox and +inserts it after the item after or at the beginning if after +is 0. + +

QListBoxItem::~QListBoxItem () [virtual] +

+Destroys the list box item. + +

bool QListBoxItem::current () const +

+ +This function is obsolete. It is provided to keep old source working. We strongly advise against using it in new code. +

+

int QListBoxItem::height ( const QListBox * lb ) const [virtual] +

+ +

Implement this function to return the height of your item. The lb parameter is the same as listBox() and is provided for +convenience and compatibility. +

The default implementation returns +QApplication::globalStrut()'s height. +

See also paint() and width(). + +

Reimplemented in QListBoxText and QListBoxPixmap. +

bool QListBoxItem::isCurrent () const +

+Returns TRUE if the item is the current item; otherwise returns +FALSE. +

See also QListBox::currentItem, QListBox::item(), and isSelected(). + +

bool QListBoxItem::isSelectable () const +

+Returns TRUE if this item is selectable (the default); otherwise +returns FALSE. +

See also setSelectable(). + +

bool QListBoxItem::isSelected () const +

+ +

Returns TRUE if the item is selected; otherwise returns FALSE. +

See also QListBox::isSelected() and isCurrent(). + +

Example: listboxcombo/listboxcombo.cpp. +

QListBox * QListBoxItem::listBox () const +

+Returns a pointer to the list box containing this item. + +

QListBoxItem * QListBoxItem::next () const +

+Returns the item that comes after this in the list box. If this is +the last item, 0 is returned. +

See also prev(). + +

void QListBoxItem::paint ( QPainter * p ) [pure virtual protected] +

+ +

Implement this function to draw your item. The painter, p, is +already open for painting. +

See also height() and width(). + +

Example: listboxcombo/listboxcombo.cpp. +

Reimplemented in QListBoxText and QListBoxPixmap. +

const QPixmap * QListBoxItem::pixmap () const [virtual] +

+Returns the pixmap associated with the item, or 0 if there isn't +one. +

The default implementation returns 0. + +

Example: listboxcombo/listboxcombo.cpp. +

Reimplemented in QListBoxPixmap. +

QListBoxItem * QListBoxItem::prev () const +

+Returns the item which comes before this in the list box. If this +is the first item, 0 is returned. +

See also next(). + +

int QListBoxItem::rtti () const [virtual] +

+Returns 0. +

Make your derived classes return their own values for rtti(), and +you can distinguish between listbox items. You should use values +greater than 1000 preferably a large random number, to allow for +extensions to this class. + +

bool QListBoxItem::selected () const +

+ +This function is obsolete. It is provided to keep old source working. We strongly advise against using it in new code. +

+

void QListBoxItem::setCustomHighlighting ( bool b ) [protected] +

+Defines whether the list box item is responsible for drawing +itself in a highlighted state when being selected. +

If b is FALSE (the default), the list box will draw some +default highlight indicator before calling paint(). +

See also selected() and paint(). + +

void QListBoxItem::setSelectable ( bool b ) +

+If b is TRUE (the default) then this item can be selected by +the user; otherwise this item cannot be selected by the user. +

See also isSelectable(). + +

void QListBoxItem::setText ( const QString & text ) [virtual protected] +

+ +

Sets the text of the QListBoxItem to text. This text is also +used for sorting. The text is not shown unless explicitly drawn in +paint(). +

See also text(). + +

QString QListBoxItem::text () const [virtual] +

+Returns the text of the item. This text is also used for sorting. +

See also setText(). + +

Example: listboxcombo/listboxcombo.cpp. +

int QListBoxItem::width ( const QListBox * lb ) const [virtual] +

+ +

Reimplement this function to return the width of your item. The lb parameter is the same as listBox() and is provided for +convenience and compatibility. +

The default implementation returns +QApplication::globalStrut()'s width. +

See also paint() and height(). + +
