Member Function Documentation

`[signal]` void QVirtualKeyboardSelectionListModel::activeItemChanged(int index)

This signal is emitted when the active item in the list changes. The UI should react to this signal by highlighting the item at index in the list.

int QVirtualKeyboardSelectionListModel::count() const

`[signal]` void QVirtualKeyboardSelectionListModel::countChanged()

`[signal]` void QVirtualKeyboardSelectionListModel::itemSelected(int index)

This signal is emitted when an item at index is selected by the user.

void QVirtualKeyboardSelectionListModel::removeItem(int index)

This method should be called when the user removes an item at position index from the list. The removal is forwarded to the input method for further processing.

Note: This function can be invoked via the meta-object system and from QML. See Q_INVOKABLE.

void QVirtualKeyboardSelectionListModel::selectItem(int index)

This method should be called when the user selects an item at position index from the list. The selection is forwarded to the input method for further processing.
