我正在使用Kivy和Button小部件制作扫雷游戏。我希望能够根据鼠标点击是左键还是右键来执行不同的操作。有人可以帮助我吗?
下面是我的Cell类和导入的模块。
请注意,当按下按钮时,将调用Cell.onPressed()函数。

on_touch_down
而不是on_press
,很快更新。请再尝试第二个示例。 - hurturkonPressed
函数替换为上面的函数。我会清除第一段代码以避免混淆。确实,当你像那样绑定时它们会发生碰撞。 - hurturkclass TouchInput(Widget): def on_touch_down(self, touch): global mouse mouse = touch.button
然后我创建了一个实例并将其添加到我的根widget中。所以现在每次点击按钮时,它只检查鼠标的状态。 def onPressed(self, instance): if mouse == 'left': print('左键!') if mouse == 'right': print('右键!') - Damon Palovaara
