我这样做是为了我的WACOM Intoos艺术平板电脑：

只需继承一个QWidget类并定义tabletEvent()方法来处理接收到的QTabletEvent事件。在

别忘了打电话给平板电脑tabletEvent.accept()方法位于处理程序末尾。在

示例：

(处理TabletPress、tabletreease和TabletMove事件)

当笔接触平板电脑表面时，生成TabletPress事件，当笔离开平板电脑表面时生成TabletRelease事件。

在这些事件之间生成一个TabletMove事件流。在

对于每个接收到的QTabletEvent，您将得到笔的位置和笔的压力。(我的平板电脑上没有倾斜信息)

请注意，我不得不将示例窗口调整为完全桌面大小，以便从整个平板电脑表面获取表事件。我不知道如何从平板电脑的所有表面捕捉事件，将其映射到widget客户端表面，如果它没有调整到完全的桌面大小。(对此问题的任何帮助都将得到极大的重视。)import sys
