qt没有任务栏按钮

C ++ new 运算符返回MainWindow对象的地址，而不是对象本身。


你需要像trhat这样的代码使用MainWindow指针：

The C++ new operator returns rthe address of the MainWindow object and not the object itself.

You need code like trhat works with a MainWindow pointer:

但重点是的，一切正常（主窗口显示，你可以alt-tab等），只有没有任务栏按钮。


你是对的，我可以尝试我上班了我没注意到它，因为编译器没有发出关于它的警告/错误！

But the point is, everything worked (main window would show, you could alt-tab to it, etc), there was only no taskbar button.

And you are right, I can try that when I get to work. I did not notice it because compiler did not issue a warning/error about it!

你需要查看MainWindow的代码。您正在调用默认构造函数。那里应该有代码来创建你的任务栏。

You will need to look at the code for MainWindow. You are calling the default constructor. There should be code there to create your task bar.
