成员函数文档编制

[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 在列表中。

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

此信号被发射当项位于 index 被用户选中。

void QVirtualKeyboardSelectionListModel:: removeItem ( int index )

应调用此方法当用户移除项在位置 index from the list. The removal is forwarded to the input method for further processing.

注意: 此函数可以被援引,通过元对象系统和从 QML。见 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.
