pyqt5。运行字符串和时钟

Question

我有一个带有标签的表格（顶部的时钟和底部的运行字符串）。我在表单中添加了 linker_by_grid （以便在调整表单大小时所有组件都可以按比例调整大小）。当我运行项目时，运行字符串中的每一秒文本都在抽搐。如果我从表单中删除 linker_by_grid，一切正常，但所有组件都不会自动调整大小以适应表单。

来自 QtDesigner 的代码：

    class Ui_Form(object):

        def setupUi(self, Form):

            Form.setObjectName("Form")

            Form.resize(498, 299)

            self.verticalLayoutWidget = QtWidgets.QWidget(Form)

            self.verticalLayoutWidget.setGeometry(QtCore.QRect(10, 10, 479, 281))

            self.verticalLayoutWidget.setObjectName("verticalLayoutWidget")

            self.verticalLayout = QtWidgets.QVBoxLayout(self.verticalLayoutWidget)

            self.verticalLayout.setContentsMargins(0, 0, 0, 0)

            self.verticalLayout.setObjectName("verticalLayout")

            self.label_2 = QtWidgets.QLabel(self.verticalLayoutWidget)

            font = QtGui.QFont()

            font.setPointSize(15)

            self.label_2.setFont(font)

            self.label_2.setText("")

            self.label_2.setAlignment(QtCore.Qt.AlignCenter)

            self.label_2.setObjectName("label_2")

            self.verticalLayout.addWidget(self.label_2)

            self.tableWidget = QtWidgets.QTableWidget(self.verticalLayoutWidget)

            self.tableWidget.setObjectName("tableWidget")

            self.tableWidget.setColumnCount(0)

            self.tableWidget.setRowCount(0)

            self.verticalLayout.addWidget(self.tableWidget)

            self.label = QtWidgets.QLabel(self.verticalLayoutWidget)

            font = QtGui.QFont()

            font.setPointSize(15)

            self.label.setFont(font)

            self.label.setObjectName("label")

            self.verticalLayout.addWidget(self.label)

            self.retranslateUi(Form)

            QtCore.QMetaObject.connectSlotsByName(Form)

        def retranslateUi(self, Form):

            _translate = QtCore.QCoreApplication.translate

            Form.setWindowTitle(_translate("Form", "Form"))

            self.label.setText(_translate("Form", "Running string ... "))
