Question

我有一个小部件，我希望能够使用鼠标从小部件内部的任何位置移动窗口，除了qcombobox或qlineedit或qpushbutton内部。

mousePressEvent初始页中定义的mouseMoveEvent和Wizard使这项工作有效。

问题是，当单击combobox时，小部件可以跳转到屏幕上的任何位置，或者qcombobox和comboboxlist分开。

这是随机发生的，结果是随机的。它可以向任何方向移动几厘米，也可以向屏幕左下方，右下方等移动。

这似乎只有在单击组合框时才会发生。

如何为movemouseevent和comboboxes禁用linedits？

Answer 1

由于问题是随机的，可能是因为尝试打开QComboBox的弹出窗口时按下了QWizard，所以避免出现问题的一种方法是使用{{ 1}}。

QApplication.startDragDistance()

使用movemouseEvent
