实例

创建基于Dialog without Buttons模板的窗口
添加两个Label，两个Line Edit，两个Push Button部件
设定Label部件的text为Name和Email Address
设定Push Button部件的text为Submit, Cancel
选定所有部件，右键选择”布局“，选择窗体布局
在两个Line Edit间添加Vertical Spacer
在第二个Line Edit和Submit间添加Vertical Spacer
保存为demoFormLayout.ui
使用pyuic生成demoFormLayout.py
创建callFormLayout.py，代码如下

from PyQt5 import QtCore, QtGui, QtWidgets

class Ui_Dialog(object):
    def setupUi(self, Dialog):
        Dialog.setObjectName("Dialog")
        Dialog.resize(400, 300)
        self.widget = QtWidgets.QWidget(Dialog)
        self.widget.setGeometry(QtCore.QRect(70, 70, 219, 129))
        self.widget.setObjectName("widget")
        self.formLayout = QtWidgets.QFormLayout(self.widget)
        self.formLayout.setContentsMargins(0, 0, 0, 0)
        self.formLayout.setObjectName("formLayout")
        self.label = QtWidgets.QLabel(self.widget)
        self.label.setObjectName("label")
        self.formLayout.setWidget(0, QtWidgets.QFormLayout.LabelRole, self.label)
        self.lineEdit = QtWidgets.QLineEdit(self.widget)
        self.lineEdit.setObjectName("lineEdit")
        self.formLayout.setWidget(0, QtWidgets.QFormLayout.FieldRole, self.lineEdit)
        self.label_2 = QtWidgets.QLabel(self.widget)
        self.label_2.setObjectName("label_2")
        self.formLayout.setWidget(2, QtWidgets.QFormLayout.LabelRole, self.label_2)
        self.lineEdit_2 = QtWidgets.QLineEdit(self.widget)
        self.lineEdit_2.setObjectName("lineEdit_2")
        self.formLayout.setWidget(2, QtWidgets.QFormLayout.FieldRole, self.lineEdit_2)
        spacerItem = QtWidgets.QSpacerItem(20, 40, QtWidgets.QSizePolicy.Minimum, QtWidgets.QSizePolicy.Expanding)
        self.formLayout.setItem(3, QtWidgets.QFormLayout.FieldRole, spacerItem)
        self.pushButton = QtWidgets.QPushButton(self.widget)
        self.pushButton.setObjectName("pushButton")
        self.formLayout.setWidget(4, QtWidgets.QFormLayout.LabelRole, self.pushButton)
        self.pushButton_2 = QtWidgets.QPushButton(self.widget)
        self.pushButton_2.setObjectName("pushButton_2")
        self.formLayout.setWidget(4, QtWidgets.QFormLayout.FieldRole, self.pushButton_2)
        spacerItem1 = QtWidgets.QSpacerItem(20, 40, QtWidgets.QSizePolicy.Minimum, QtWidgets.QSizePolicy.Expanding)
        self.formLayout.setItem(1, QtWidgets.QFormLayout.FieldRole, spacerItem1)

        self.retranslateUi(Dialog)
        QtCore.QMetaObject.connectSlotsByName(Dialog)

    def retranslateUi(self, Dialog):
        _translate = QtCore.QCoreApplication.translate
        Dialog.setWindowTitle(_translate("Dialog", "Dialog"))
        self.label.setText(_translate("Dialog", "Name "))
        self.label_2.setText(_translate("Dialog", "Email Address"))
        self.pushButton.setText(_translate("Dialog", "Cancel"))
        self.pushButton_2.setText(_translate("Dialog", "Submit"))
if __name__ == "__main__":
    import sys
    app = QtWidgets.QApplication(sys.argv)
    Dialog = QtWidgets.QDialog()
    ui = Ui_Dialog()
    ui.setupUi(Dialog)
    Dialog.show()
    sys.exit(app.exec_())
