Python基础之实现界面和代码分离
第一步：用QT Designer画一个TreeWidget，存为treeview4.ui，这个处理前面TreeWidget那一节讲过，这里不细讲
treeview4.py
# -*- coding: utf-8 -*- # Form implementation generated from reading ui file 'treeview4.ui' # # Created by: PyQt5 UI code generator 5.13.0 # # WARNING! All changes made in this file will be lost! from PyQt5 import QtCore, QtGui, QtWidgets class Ui_MainWindow(object): def setupUi(self, MainWindow): MainWindow.setObjectName("MainWindow") MainWindow.resize(800, 600) self.centralwidget = QtWidgets.QWidget(MainWindow) self.centralwidget.setObjectName("centralwidget") self.treeWidget = QtWidgets.QTreeWidget(self.centralwidget) self.treeWidget.setGeometry(QtCore.QRect(150, 80, 411, 341)) self.treeWidget.setObjectName("treeWidget") MainWindow.setCentralWidget(self.centralwidget) self.menubar = QtWidgets.QMenuBar(MainWindow) self.menubar.setGeometry(QtCore.QRect(0, 0, 800, 21)) self.menubar.setObjectName("menubar") MainWindow.setMenuBar(self.menubar) self.statusbar = QtWidgets.QStatusBar(MainWindow) self.statusbar.setObjectName("statusbar") MainWindow.setStatusBar(self.statusbar) self.retranslateUi(MainWindow) QtCore.QMetaObject.connectSlotsByName(MainWindow) def retranslateUi(self, MainWindow): _translate = QtCore.QCoreApplication.translate MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow")) self.treeWidget.headerItem().setText(0, _translate("MainWindow", "Key")) self.treeWidget.headerItem().setText(1, _translate("MainWindow", "Value"))
第二步：代码分离。新建一个treeview4_test.py
from PyQt5.QtWidgets import QApplication, QMainWindow, QFileDialog from PyQt5 import QtCore, QtGui, QtWidgets import treeview4 import treeview_data import sys class MainCode(QMainWindow, treeview4.Ui_MainWindow): def __init__(self): QMainWindow.__init__(self) treeview4.Ui_MainWindow.__init__(self) self.setupUi(self) # 设置列宽 self.treeWidget.setColumnWidth(0, 200) _translate = QtCore.QCoreApplication.translate self.initial_tree_view(_translate) self.treeWidget.expandAll() def initial_tree_view(self, _translate): list_objects = [] test1 = treeview_data.DataCollection() test1.set_module({"Test1": "waiting"}) test1.add_item({"a1": "waiting"}) test1.add_item({"b1": "waiting"}) test1.add_item({"c1": "waiting"}) list_objects.append(test1) test2 = treeview_data.DataCollection() test2.set_module({"Test2": "waiting"}) test2.add_item({"a2": "waiting"}) test2.add_item({"b2": "waiting"}) test2.add_item({"c2": "waiting"}) test2.add_item({"d2": "waiting"}) list_objects.append(test2) test3 = treeview_data.DataCollection() test3.set_module({"Test3": "waiting"}) test3.add_item({"a2": "waiting"}) test3.add_item({"b2": "waiting"}) test3.add_item({"c2": "waiting"}) test3.add_item({"d2": "waiting"}) list_objects.append(test3) for object_num, object_module in enumerate(list_objects): item_0 = QtWidgets.QTreeWidgetItem(self.treeWidget) brush = QtGui.QBrush(QtGui.QColor(176, 165, 172)) brush.setStyle(QtCore.Qt.SolidPattern) item_0.setBackground(0, brush) for module_name, module_result in object_module.module.items(): brush = QtGui.QBrush(QtGui.QColor(0, 255, 0)) brush.setStyle(QtCore.Qt.SolidPattern) item_0.setBackground(1, brush) self.treeWidget.topLevelItem(object_num).setText(0, _translate("MainWindow", module_name)) self.treeWidget.topLevelItem(object_num).setText(1, _translate("MainWindow", module_result)) for item_num, item_dic in enumerate(object_module.items): for item_name, item_result in item_dic.items(): item_1 = QtWidgets.QTreeWidgetItem(item_0) self.treeWidget.topLevelItem(object_num).child(item_num).setText(0, _translate("MainWindow", item_name)) self.treeWidget.topLevelItem(object_num).child(item_num).setText(1, _translate("MainWindow", item_result)) if __name__ == "__main__": app = QApplication(sys.argv) md = MainCode() md.show() app.exec_() # sys.exit(app.exec_())
