我正在尝试编写一个包含treewidget的python程序,并且能够在用鼠标右键单击后添加,重命名和删除集群。 我对python很新,到目前为止这是我的代码:
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_())
有人可以告诉我如何在某个群集上单击鼠标右键后打开弹出菜单? 提前谢谢!
答案 0 :(得分:0)
我找到了答案。 它看起来像这样:
def new_cluster(self):
print "New Cluster"
def rename_cluster(self):
print "Rename cluster"
def delete_cluster(self):
print "Delete cluster"
def create_popup_menu(self, parent=None):
self.popup_menu = QtGui.QMenu(parent)
self.popup_menu.addAction("New", self.new_cluster)
self.popup_menu.addAction("Rename", self.rename_cluster)
self.popup_menu.addSeparator()
self.popup_menu.addAction("Delete", self.delete_cluster)
def on_context_menu(self, pos):
node = self.treeWidget.mapToGlobal(pos)
self.popup_menu.exec_(self.treeWidget.mapToGlobal(pos))
