PySide：根据按钮的位置和 window 的边缘创建弹出窗口

Question

我想在单击按钮的位置创建一个弹出窗口，并沿现有 window.

的左边缘偏移该弹出窗口

现在我可以很好地确定按钮的位置，但 window 的位置似乎有点偏离，因为在创建弹出窗口时它向左偏移了大约 200 像素。我在我的代码中评论了下面的相关部分。感谢任何 help/critiques.

解法：

# Get button position                                          
btn_global_point = self.button_pos.mapToGlobal(self.button_pos.rect().topLeft())  

# Get window position  
win_global_point = self.toolWindow.mapToGlobal(self.rect().topLeft()) 

self.move(win_global_point.x(), btn_global_point.y())

Answer 1

如果我明白你想要达到什么目的，你只需要保留按钮位置的 y 值 和 x 值 的 window 个位置。

所以试试这个代码：

    # Get y button position                                          
    btn_global_point_y = self.button_pos.mapToGlobal(self.button_pos.rect().topLeft()).y()  

    # Get window position  
    win_global_point_x = self.mapToGlobal(self.rect().topLeft()).x() 

    self.move(win_global_point_x, btn_global_point_y)

使用此行，您可以将弹出窗口 window 移动到按钮的高度并将其对齐到 window 的左边缘。
