QRect WarpTreeView::visualRect

(

const QModelIndex &

)

const

Return the bounding rectangle of the given QModelIndex.

void WarpTreeView::scrollTo	(	const QModelIndex &	,
		QAbstractItemView::ScrollHint
	)

Move the given index to the center of the view. The ScrollHint has no effect.

QModelIndex WarpTreeView::indexAt

(

const QPoint &

)

const

Returns the model index of the item at the viewport coordinates.

QModelIndex WarpTreeView::moveCursor	(	QAbstractItemView::CursorAction	,
		Qt::KeyboardModifiers
	)

Moves the cursor in the view according to the given cursorAction and keyboard modifiers specified by modifiers.

int WarpTreeView::horizontalOffset

(

)

const

Returns the horizontal offset of the view.

(

)

const

Returns the vertical offset of the view.

bool WarpTreeView::isIndexHidden

(

const QModelIndex &

)

const

QRegion WarpTreeView::visualRegionForSelection

(

const QItemSelection &

)

const

Returns the region from the viewport of the items in the given selection.

void WarpTreeView::currentChanged	(	const QModelIndex &	current,
