单击鼠标时不调用 Qt 重载鼠标事件处理程序
我正在使用我自己的名为 chessCV 的类编写一个国际象棋程序，该类派生自 QGraphicsView ，然后我将其作为成员添加到我的 MainWindow 类中。我似乎无法让程序执行我重载的 MousePressEvent(QMouseEvent * event) 函数。它永远不会被调用。我想这可能与我从 QGraphicsView 继承的方式有关，但我尝试在 MainWindow 类中重载 MousePressEvent(QMouseEvent * event) ，但这不是被称为。我完全被难住了。任何帮助表示赞赏。谢谢大家。
I am writing a chess program using my own class called chessCV, which is derived from QGraphicsView, and then I am adding it to my MainWindow class as a member. I cannot seem to get the program to execute the MousePressEvent(QMouseEvent * event) function, which I overloaded. It never gets called. I thought maybe it had to do with the way that I inherited from QGraphicsView, but I tried overloading the MousePressEvent(QMouseEvent * event) in the MainWindow class, and that is not being called either. I am completely stumped. Any help is appreciated. Thanks everyone.

如果您尝试重载
QGraphicsView::mousePressEvent(QMouseEvent* event)，则 m 不应大写。If you are trying to overload
QGraphicsView::mousePressEvent(QMouseEvent* event), the m should not be capitalized.
