    copied!<p>I'm trying to write a program with python that contains a treewidget and having the ability to add, rename and remove cluster after clicking with the right mouse button on them. I'm quite new with python and this is my code so far:</p> <pre><code>from PyQt4 import QtCore, QtGui try: _fromUtf8 = QtCore.QString.fromUtf8 except AttributeError: def _fromUtf8(s): return s try: _encoding = QtGui.QApplication.UnicodeUTF8 def _translate(context, text, disambig): return QtGui.QApplication.translate(context, text, disambig, _encoding) except AttributeError: def _translate(context, text, disambig): return QtGui.QApplication.translate(context, text, disambig) class Ui_MainWindow(object): def setupUi(self, MainWindow): MainWindow.setObjectName(_fromUtf8("MainWindow")) MainWindow.resize(800, 600) self.centralwidget = QtGui.QWidget(MainWindow) self.centralwidget.setObjectName(_fromUtf8("centralwidget")) self.treeWidget = QtGui.QTreeWidget(self.centralwidget) self.treeWidget.setGeometry(QtCore.QRect(155, 50, 481, 361)) self.treeWidget.setObjectName(_fromUtf8("treeWidget")) MainWindow.setCentralWidget(self.centralwidget) self.menubar = QtGui.QMenuBar(MainWindow) self.menubar.setGeometry(QtCore.QRect(0, 0, 800, 25)) self.menubar.setObjectName(_fromUtf8("menubar")) MainWindow.setMenuBar(self.menubar) self.statusbar = QtGui.QStatusBar(MainWindow) self.statusbar.setObjectName(_fromUtf8("statusbar")) MainWindow.setStatusBar(self.statusbar) self.retranslateUi(MainWindow) self.buildingTree() QtCore.QMetaObject.connectSlotsByName(MainWindow) def retranslateUi(self, MainWindow): MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow", None)) self.treeWidget.headerItem().setText(0, _translate("MainWindow", "Assignment1", None)) __sortingEnabled = self.treeWidget.isSortingEnabled() def buildingTree(self): item_0 = QtGui.QTreeWidgetItem(self.treeWidget) item_1 = QtGui.QTreeWidgetItem(item_0) item_2 = QtGui.QTreeWidgetItem(item_1) item_1 = QtGui.QTreeWidgetItem(item_0) item_2 = QtGui.QTreeWidgetItem(item_1) self.treeWidget.setSortingEnabled(False) self.treeWidget.topLevelItem(0).setText(0, _translate("MainWindow", "default", None)) self.treeWidget.topLevelItem(0).child(0).setText(0, _translate("MainWindow", "cluster1", None)) self.treeWidget.topLevelItem(0).child(0).child(0).setText(0, _translate("MainWindow", "clusterA", None)) self.treeWidget.topLevelItem(0).child(1).setText(0, _translate("MainWindow", "cluster2", None)) self.treeWidget.topLevelItem(0).child(1).child(0).setText(0, _translate("MainWindow", "clusterA", None)) if __name__ == "__main__": import sys app = QtGui.QApplication(sys.argv) MainWindow = QtGui.QMainWindow() ui = Ui_MainWindow() ui.setupUi(MainWindow) MainWindow.show() sys.exit(app.exec_()) </code></pre> <p>Could someone please tell me how do I open a popup menu after clicking with the right mouse button on a certain cluster?
