PySide：根据现有 UI 元素的位置在某个位置创建 window

Question

我正在 Maya 中创建一个具有一些弹出窗口的工具。我希望弹出窗口出现在基于您单击的 UI 元素的设置位置。

当我运行脚本时，该工具出现在我的光标位置（这很好用）。然后，当您左键单击该按钮时，另一个 window 弹出（这不能正常工作）。

问题是弹出窗口 window 出现在我屏幕的左上角，而不是 QPushButton 的位置。我想如果我在我的 Popup_Window class 的 move_ui 方法中用 self.button_popup.pos() 替换 QtGui.QCursor.pos() 它会起作用......但它没有't.

有什么想法吗？这是我到目前为止在右侧评论的关键区域：

from PySide import QtCore, QtGui
from shiboken import wrapInstance 

def get_parent():
    ptr = mui.MQtUtil.mainWindow()
    return wrapInstance( long( ptr ), QtGui.QWidget )

    def on_left_click(self):

        self.move(pos.x()+20, pos.y()+15)

问题是 widget.pos() 给你的小部件的相对位置（相对于 window）非常小，接近 (0,0)，即左上角window space.

如果你想要一个小部件的全局屏幕位置，你必须写：

rel_pos = widget.pos()
pos = widget.mapToGlobal(rel_pos)

所以你在Popup_Windowclass中的move_UI函数变成：

def move_UI( self ):
        ''' Moves the UI to the widget position '''
        rel_pos = self.button_pos.pos()                        # Using the button's position to determine window position
        pos = self.button_pos.mapToGlobal(rel_pos)
        self.move(pos.x()+20, pos.y()+15)
