Constructor & Destructor Documentation

KExtendableItemDelegate::KExtendableItemDelegate ( QAbstractItemView * parent )

Create a new KExtendableItemDelegate that belongs to parent.

In contrast to generic QAbstractItemDelegates, an instance of this class can only ever be the delegate for one instance of af QAbstractItemView subclass.

Member Function Documentation

void KExtendableItemDelegate::contractAll ( )

Close all extenders and delete all extender widgets.

Definition at line 130 of file kextendableitemdelegate.cpp.

void KExtendableItemDelegate::contractItem ( const QModelIndex & index )

Remove the extender of item at index from the view.

The extender widget will be deleted.

Definition at line 111 of file kextendableitemdelegate.cpp.

QPixmap KExtendableItemDelegate::contractPixmap ( )

protected

Return the pixmap that is displayed to contract an item.

Definition at line 446 of file kextendableitemdelegate.cpp.

void KExtendableItemDelegate::extenderCreated	(	QWidget *	extender,
		const QModelIndex &	index
	)

signal

This signal indicates that the item at index was extended with extender.

void KExtendableItemDelegate::extenderDestroyed	(	QWidget *	extender,
		const QModelIndex &	index
	)

signal

This signal indicates that the extender belonging to index has emitted the destroyed() signal.

QRect KExtendableItemDelegate::extenderRect	(	QWidget *	extender,
		const QStyleOptionViewItem &	option,
		const QModelIndex &	index
	)		const

protected

Reimplement this function to fine-tune the position of the extender.

option.rect will be a rectangle that is as wide as the viewport and as high as the usual item height plus the extender size hint's height. Its upper left corner will be at the upper left corner of the usual item. You can place the returned rectangle of this function anywhere inside that area.

Definition at line 314 of file kextendableitemdelegate.cpp.

void KExtendableItemDelegate::extendItem	(	QWidget *	extender,
		const QModelIndex &	index
	)

Insert the extender for item at index into the view.

If you need a parent for the extender at construction time, use the itemview's viewport(). The delegate takes ownership of the extender; the extender will also be reparented and resized to the viewport.

Definition at line 86 of file kextendableitemdelegate.cpp.

QPixmap KExtendableItemDelegate::extendPixmap ( )

protected

Return the pixmap that is displayed to extend an item.

Definition at line 440 of file kextendableitemdelegate.cpp.

bool KExtendableItemDelegate::isExtended ( const QModelIndex & index ) const

Return whether there is an extender that belongs to index.

Definition at line 172 of file kextendableitemdelegate.cpp.
