復合窗口部件就是由兩個或者多個其他窗口部件組合在一起的窗口部件。在大的工程項目中創建可重復使用的復合窗口部件能夠節約大量時間。本文就是通過python3+PyQt5實現。

#!/usr/bin/env python3import sysfrom PyQt5.QtCore import Qtfrom PyQt5.QtWidgets import (Qapplication, QBoxLayout, QDialog, QDialogButtonBox, QGridLayout, QLabel, QLineEdit, QTextEdit, QVBoxLayout, QWidget)LEFT, ABOVE = range(2)class LabelledLineEdit(QWidget): def __init__(self, labelText="", position=LEFT, parent=None): super(LabelledLineEdit, self).__init__(parent) self.label = QLabel(labelText) self.lineEdit = QLineEdit() self.label.setBuddy(self.lineEdit) layout = QBoxLayout(QBoxLayout.LeftToRight if position == LEFT else QBoxLayout.TopToBottom) layout.addWidget(self.label) layout.addWidget(self.lineEdit) self.setLayout(layout)class LabelledTextEdit(QWidget): def __init__(self, labelText="", position=LEFT, parent=None): super(LabelledTextEdit, self).__init__(parent) self.label = QLabel(labelText) self.textEdit = QTextEdit() self.label.setBuddy(self.textEdit) layout = QBoxLayout(QBoxLayout.LeftToRight if position == LEFT else QBoxLayout.TopToBottom) layout.addWidget(self.label) layout.addWidget(self.textEdit) self.setLayout(layout)class Dialog(QDialog): def __init__(self, address=None, parent=None): super(Dialog, self).__init__(parent) self.street = LabelledLineEdit("&Street:") self.city = LabelledLineEdit("&City:") self.state = LabelledLineEdit("St&ate:") self.zipcode = LabelledLineEdit("&Zipcode:") self.notes = LabelledTextEdit("&Notes:", ABOVE) if address is not None: self.street.lineEdit.setText(address.get("street", "")) self.city.lineEdit.setText(address.get("city", "")) self.state.lineEdit.setText(address.get("state", "")) self.zipcode.lineEdit.setText(address.get("zipcode", "")) self.notes.textEdit.setPlainText(address.get("notes", "")) buttonBox = QDialogButtonBox(QDialogButtonBox.Ok| QDialogButtonBox.Cancel) grid = QGridLayout() grid.addWidget(self.street, 0, 0) grid.addWidget(self.city, 0, 1) grid.addWidget(self.state, 1, 0) grid.addWidget(self.zipcode, 1, 1) grid.addWidget(self.notes, 2, 0, 1, 2) layout = QVBoxLayout() layout.addLayout(grid) layout.addWidget(buttonBox) self.setLayout(layout) buttonBox.accepted.connect(self.accept) buttonBox.rejected.connect(self.reject) self.setWindowTitle("Labelled Widgets")if __name__ == "__main__": fakeAddress = dict(street="3200 Mount Vernon Memorial Highway", city="Mount Vernon", state="Virginia", zipcode="22121") app = QApplication(sys.argv) form = Dialog(fakeAddress) form.show() app.exec_() 運行結果：這里寫圖片描述
