Member Function Documentation

currentChanged

void TabnavTreeView::currentChanged ( const QModelIndex &  current, const QModelIndex &  previous  )

protectedslot

Relays the QAbstractItemView::currentChanged notification as the currentItemChanged() signal so that external observers can connect without subclassing.

Parameters

current	The newly current model index.
previous	The previously current model index.

currentItemChanged

void TabnavTreeView::currentItemChanged ( const QModelIndex &  current, const QModelIndex &  previous  )

signal

Emitted whenever the current item changes.

Parameters

current	The newly current model index.
previous	The previously current model index.

This signal is emitted whenever the current item changes.

previous is the item that previously had the focus; current is the new current item.

moveCursor()

QModelIndex TabnavTreeView::moveCursor	(	CursorAction	cursorAction,
		Qt::KeyboardModifiers	modifiers
	)

Returns the index the view should move to for a given cursor action.

Overrides the default behaviour so that CursorAction::MoveNext (Tab) and CursorAction::MovePrevious (Shift+Tab) advance through columns within the current row rather than moving to adjacent rows.

Parameters

cursorAction	The navigation action requested (e.g. MoveNext, MovePrevious).
modifiers	Active keyboard modifiers at the time of the action.

Returns

The model index that should receive focus.
