如果我在QT Designer中创建UI(并将UI导入脚本),如何在脚本中隐藏和显示选项卡?

class Tool(QMainWindow, uiTool.Ui_Tool):
    def __init__(self):
        super(Tool, self).__init__()
        # SETUP UI
        self.setupUi(self)

        # self.tabWidget.removeTab() ???

无法在选项卡小部件中隐藏/显示选项卡,因此您需要删除并替换它们。

import sys
from PyQt5 import QtCore, QtWidgets

class Ui_Form(object):
    def setupUi(self, Form):
        Form.setObjectName("Form")
        Form.resize(354, 268)
        self.gridLayout = QtWidgets.QGridLayout(Form)
        self.gridLayout.setObjectName("gridLayout")
        self.tabWidget = QtWidgets.QTabWidget(Form)
        self.tabWidget.setObjectName("tabWidget")
        self.tabRed = QtWidgets.QWidget()
        self.tabRed.setObjectName("tabRed")
        self.tabWidget.addTab(self.tabRed, "")
        self.tabBlue = QtWidgets.QWidget()
        self.tabBlue.setObjectName("tabBlue")
        self.tabWidget.addTab(self.tabBlue, "")
        self.tabGreen = QtWidgets.QWidget()
        self.tabGreen.setObjectName("tabGreen")
        self.tabWidget.addTab(self.tabGreen, "")
        self.gridLayout.addWidget(self.tabWidget, 0, 0, 1, 2)
        self.buttonRemove = QtWidgets.QPushButton(Form)
        self.buttonRemove.setObjectName("buttonRemove")
        self.gridLayout.addWidget(self.buttonRemove, 1, 0, 1, 1)

        self.buttonRestore.setObjectName("buttonRestore")
        self.gridLayout.addWidget(self.buttonRestore, 1, 1, 1, 1)

        self.retranslateUi(Form)
        self.tabWidget.setCurrentIndex(2)
        QtCore.QMetaObject.connectSlotsByName(Form)

                self.tabWidget.tabText(index),
                ))

        index = self.tabWidget.currentIndex()
        if index >= 0:
            self.tabWidget.removeTab(index)

    def handleButtonRestore(self):
        for page, title in self.tab_pages:
            if self.tabWidget.indexOf(page) < 0:
                self.tabWidget.addTab(page, title)

if __name__ == '__main__':

    app = QtWidgets.QApplication(sys.argv)
    window = Window()
    window.setGeometry(600, 100, 300, 200)
    window.show()
    sys.exit(app.exec_())
