python - pyqt5。运行字符串和时钟
问题描述
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 ... "))
if __name__ == "__main__":
import sys
app = QtWidgets.QApplication(sys.argv)
Form = QtWidgets.QWidget()
ui = Ui_Form()
ui.setupUi(Form)
Form.show()
sys.exit(app.exec_()) ```
main file:

解决方案
您需要label从layout
