在 PyQt5 窗口中显示结果

  • 772

如何在主窗口中显示结果？我做出了选择，通过按下按钮，我将函数的结果输出到终端，但是如何输出到这个窗口或让一个新窗口，要创建什么小部件？

import sys
from PyQt5.QtCore import *

class stackedExample(QWidget):

    def do_leftbar(self):
        self.leftlist.insertItem(0, 'Сравнение справочников')               # insertItem(позиция в списке, текст)
        self.leftlist.insertItem(1, 'Редактирование справочников')
        # self.leftlist.insertItem(2, 'Будущий функционал')

        self.stack1UI()
        self.stack2UI()

        self.Stack = QStackedWidget(self)

        self.Stack.addWidget(self.stack1)    # возвращает индекс виджета addWidget
        self.Stack.addWidget(self.stack2)



        hbox = QHBoxLayout(self)   # расположение макета
        hbox.addWidget(self.leftlist)
        hbox.addWidget(self.Stack)

        self.setLayout(hbox)
        self.leftlist.currentRowChanged.connect(self.display)
        self.button.clicked.connect(self.gooo)
        self.setGeometry(100, 100, 500, 500)
        self.setWindowTitle('StackedWidget demo')
        self.show()

    def gooo(self):
        if(self.L1.isChecked()):
            print("L1 tyt my_function")
        elif (self.L2.isChecked()):

        self.L2 = QRadioButton("L2")
        self.L3 = QRadioButton("L3")

        face.addWidget(self.L2)
        face.addWidget(self.L3)
        layout.addRow(QLabel("select"), face)
        layout.addWidget(self.button)
        self.stack1.setLayout(layout)


    def stack2UI(self):
        layout = QFormLayout()
        self.stack2.setLayout(layout)

    def display(self,i):
        print(i)
        self.Stack.setCurrentIndex(i)


class great(QMainWindow, QWidget):
    def __init__(self):
        super().__init__()
        a = stackedExample()
        self.setGeometry(100, 100, 1000, 900)
        self.setCentralWidget(a)
        self.show()


def main():
        app = QApplication(sys.argv)
        ex = stackedExample()
        sys.exit(app.exec_())

    我建议添加一个小部件QTextEdit()并在那里显示所有内容。
