Descripción detallada

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().

Documentación del constructor y destructor

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.

QListBoxItem::QListBoxItem ( QListBox * listbox = 0 )

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

virtual QListBoxItem::~QListBoxItem ( ) [virtual]

Documentación de las funciones miembro

bool QListBoxItem::current ( ) const [inline]

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.

Reimplementado en CompletionItem, QListBoxText, QListBoxPixmap, QFileDialogPrivate::MCItem, QListBoxText, QListBoxPixmap y CompletionItem.

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

Reimplementado en CompletionItem, QListBoxText, QListBoxPixmap, QFileDialogPrivate::MCItem, QListBoxText, QListBoxPixmap y CompletionItem.

bool QListBoxItem::isCurrent ( ) const

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

Ver también:: QListBox::currentItem(), QListBox::item(), isSelected()

bool QListBoxItem::isSelectable ( ) const

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

Ver también:: setSelectable()

bool QListBoxItem::isSelectable ( ) const

bool QListBoxItem::isSelected ( ) const [inline]

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

Ver también:: QListBox::isSelected(), isCurrent()

bool QListBoxItem::isSelected ( ) const [inline]

QListBox * QListBoxItem::listBox ( ) const

Returns a pointer to the list box containing this item.

QListBox* QListBoxItem::listBox ( ) const

QListBoxItem * QListBoxItem::next ( ) const

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

Ver también:: prev()

QListBoxItem* QListBoxItem::next ( ) const

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

Implementado en CompletionItem, QListBoxText, QListBoxPixmap, QFileDialogPrivate::MCItem, QListBoxText, QListBoxPixmap, BoldListBoxText y CompletionItem.

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

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

Ver también:: height(), width()

Implementado en CompletionItem, QListBoxText, QListBoxPixmap, QFileDialogPrivate::MCItem, QListBoxText, QListBoxPixmap, BoldListBoxText y CompletionItem.

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

Reimplementado en QListBoxPixmap, QFileDialogPrivate::MCItem y 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.

Reimplementado en QListBoxPixmap, QFileDialogPrivate::MCItem y 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.

Ver también:: next()

QListBoxItem* QListBoxItem::prev ( ) const

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.

Reimplementado en QListBoxText, QListBoxPixmap, QListBoxText y QListBoxPixmap.

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

Reimplementado en QListBoxText, QListBoxPixmap, QListBoxText y QListBoxPixmap.

bool QListBoxItem::selected ( ) const [inline]

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().

Ver también:: selected(), paint()

void QListBoxItem::setCustomHighlighting ( bool ) [protected]

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.

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

Reimplementado en EditableListBoxItem.

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

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().

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.
