python - PyQt5，将变量列表传递给另一个类

问题描述

该程序有 2 个窗口，一个是主窗口，另一个是结果窗口。我想将在 getValue() 函数中获得值的数据传递给另一个类，即结果窗口。

#### THIS PARAMETERS SHOULD PASS TO THE BILLETCALCULATIONRESULTS WINDOW TO CALCULATE ###
    def GetValues(self):
        self.Diameter = float(self.DiameterQline.text())
        self.Height = float(self.HeightQline.text())
        self.StartTemp = float(self.StartTempQline.text())
        self.FinalTemp = float(self.FinalTempQline.text())
        self.HeatingTime = float(self.HeatingTimeQline.text())

我想在另一个窗口中进行计算并将结果打印到屏幕上。像

class BilletCalculationResults(QWidget):
    def calc():
      return str(Main.diameter  * 2 )



def billetCalculationPageDesign(self):
      ### BILLET RESULTS OF CALCULATION PAGE DESIGN ###
      self.billetCalSurfaceAreaLabel = QLabel("Surface Area : ")
      self.billetCalSurfaceAreaLabel.setStyleSheet('font-size: 12pt; font-family: arial,sans-serif')
      str = self.calc()
      self.billetCalSurfaceAreaLabelResult = QLabel(str)

您可以在下面找到所有代码。谢谢

解决方案

您几乎拥有它，只需获取值EDIT(1)并将它们添加到您的第二个窗口类的构造函数中EDIT(2)。您也可以将它们保存到变量中，但作为示例，我将值打印到命令行Edit(3)。

...

    def billetCalculationResults(self):

        self.GetValues()                                                    # EDIT(1) by Shraft      
        self.billetCalculation = BilletCalculationResults(self.Diameter,    # EDIT
                self.Height,self.StartTemp,self.FinalTemp,self.HeatingTime) # EDIT
        self.close()                                                        # EDIT


    def GetValues(self):

        self.Diameter = float(self.DiameterQline.text())
        self.Height = float(self.HeightQline.text())
        self.StartTemp = float(self.StartTempQline.text())
        self.FinalTemp = float(self.FinalTempQline.text())
        self.HeatingTime = float(self.HeatingTimeQline.text())


class BilletCalculationResults(QWidget):
      def __init__(self, diameter, height, startTemp, finalTemp, heatingTime):      # EDIT(2) by Shraft  
          super().__init__()

          print(diameter)               # EDIT(3) by Shraft  
          print(height)                 # EDIT
          print(startTemp)              # EDIT
          print(finalTemp)              # EDIT
          print(heatingTime)            # EDIT

          self.setWindowTitle("Calculation Results")
          self.setGeometry(450,150,350,600)
          ####CONSTRUCTION OF THE FIRST BILLET CLASS ###
          self.UI()
          self.show()
