pyqt 弹出框自适应位置

pyqt弹出框自适应位置，图片设置最大宽高，同比例缩放。

调用代码：

  

   

    

     

    
    

     

              dialog = QimgDialog(params)
     
    
   

    

     

    
    

     

              dialog.setWindowModality(Qt.ApplicationModal) # 设置窗口的属性为ApplicationModal模态，用户只有关闭弹窗后，才能关闭主界面
     
    
   

    

     

    
    

     

              dialog.exec_()
     
    
  
 

qt_dialog.py

  

   

    

     

    
    

     

      import os
     
    
   

    

     

    
    

     
 
     
    
   

    

     

    
    

     

      from PyQt5 import QtCore
     
    
   

    

     

    
    

     

      from PyQt5.QtCore import pyqtSignal, Qt
     
    
   

    

     

    
    

     

      from PyQt5.QtGui import QPixmap

        super(QimgDialog, self).__init__(parent)
     
    
   

    

     

    
    

     

              self.initUI(params)

              desktop = QApplication.desktop()
