Question

我正在使用PYQT5制作一个有2个标签的GUI应用程序。在一个选项卡（'tImp'）上我想使用文件浏览器，在另一个选项卡（tRec）上我想要一个按钮。我编写了我想在选项卡上看到的内容，但是当我执行脚本时，我看到了标签，但没有看到内容（文件浏览器和按钮）。以下是我到目前为止：

import sys from PyQt5.QtWidgets import QMainWindow, QApplication, QPushButton, QWidget, QAction, QTabWidget,QVBoxLayout, QInputDialog, QLineEdit, QFileDialog from PyQt5.QtGui import QIcon

class App(QMainWindow):

    def __init__(self):
        super().__init__()
        self.title = 'Budget'
        self.left = 10
        self.top = 40
        self.width = 1200
        self.height = 600
        self.setWindowTitle(self.title)
        self.setGeometry(self.left, self.top, self.width, self.height)

        self.table_widget = MyTableWidget(self)
        self.setCentralWidget(self.table_widget)

        self.show()

class MyTableWidget(QWidget):     

    def __init__(self, parent):   
        super(QWidget, self).__init__(parent)
        self.layout = QVBoxLayout(self)

        # Initialize tab screen
        self.tabs = QTabWidget()
        self.tImp = QWidget()   
        self.tRec = QWidget()
        self.tabs.resize(1200,600) 

        # Create Import tab
        def tImp():
            self.tImp.layout = QVBoxLayout(self)
            self.tImp.layout.addWidget(self.openFileNamesDialog)
            self.tImp.setLayout(self.tImp.layout)

        # Create file browser Widget        
        def openFileNamesDialog(self):    
            options = QFileDialog.Options()
            options |= QFileDialog.DontUseNativeDialog
            files, _ = QFileDialog.getOpenFileNames(self,"QFileDialog.getOpenFileNames()", "","All Files (*);;Format Files (*.csv)", options=options)
            if files:
                print(files)     

        # Create Reconcile tab
        def tRec():
            self.tRec.layout = QVBoxLayout(self)
            self.pushButton1 = QPushButton("Commit")
            self.tRec.layout.addWidget(self.pushButton1)
            self.tRec.setLayout(self.tRec.layout)

        # Add tabs
        self.tabs.addTab(self.tImp,"Import")
        self.tabs.addTab(self.tRec,"Reconcile")

        # Add tabs to widget        
        self.layout.addWidget(self.tabs)
        self.setLayout(self.layout)

if __name__ == '__main__':
    app = QApplication(sys.argv)
    ex = App()
    sys.exit(app.exec_())

任何帮助都将不胜感激。

您定义了名为tImp()和tRec()的函数来设置小部件，但您从不调用这些函数。

python pyqt5选项卡内容不显示
