如何用qtableview中右键单击的单元格中的显示文本填充上下文菜单操作“search:”。理想情况下,我希望菜单项显示单元格的文本。在本例中,它会说“search:45”,如果用户单击操作,它会设置qlineedit的文本。

导入系统从Pyside导入qtcore,qtgui 类示例(qtgui.qwidget): 定义初始化(self,*args,**kwargs): super(例如,self)。初始化(*args,**kwargs) #控制型号=qtgui.qstandarditemmodel(5,3) model.setHorizontalHeaderLabels(['name'、'age'、'career']) 人=[ '姓名':'凯文','年龄':5,'职业':'运动员', 'name':'maggie','age':13,'career':'banker', 'name':'leslie','age':32,'career':'banker', '姓名':'艾米丽','年龄':45,'职业':'运动员', 'name':'david','age':27,'career':'banker', 'name':'marie','age':63,'career':'secretary' ] 对于行,枚举中的obj(人): model.setItem(行,0,项) item=qtgui.qstandarditem(str(obj[‘age’)) model.setitem(行,1,项) item=qtgui.qstandarditem(obj[职业]) model.setitem(行,2,项) proxy_model=qtgui.qsortfilterproxymodel()。 proxy_model.setSourceModel(模型) #控制 self.ui_table=qtgui.qtableview()。 self.ui_table.setEditTriggers(qtgui.qabstratemView.noEditTriggers) self.ui_table.setSelectionBehavior(qtgui.qabstratemView.selectRows) self.ui_table.setselection模式(qtgui.qabstratemview.singleselection) self.ui_table.setmodel(代理\u模型) self.ui_table.setContextMenuPolicy(qtcore.qt.customContextMenu) self.ui_search=qtgui.qlineedit()。 #行动 self.act_search_keyword=qtgui.qaction('search',self) 菜单菜单 self.context_menu=qtgui.qmenu('file') self.context_menu.addaction(self.act_search_关键字) #敷设总管 lay_main=qtgui.qvboxlayout()。 lay_main.addwidget(self.ui_搜索) lay_main.addwidget(self.ui_表格) 自设置布局(主布局) #连接 self.ui_table.customContextMenuRequested.connect(self.open_context_菜单) def打开上下文菜单(self,point): self.context_menu.exec_uu(qtgui.qcursor.pos()) 如果“名称”= app=qtgui.qapplication(系统argv) ex=示例() 例如,show()) 系统退出(app.exec_u())

您必须在插槽中创建菜单,并使用该位置通过 indexAt() 返回 QModelIndex

    ...
    self.ui_search = QtGui.QLineEdit()

    # lay main
    lay_main = QtGui.QVBoxLayout()
    lay_main.addWidget(self.ui_search)
    lay_main.addWidget(self.ui_table)
    self.setLayout(lay_main)

    # connections
    self.ui_table.customContextMenuRequested.connect(self.open_context_menu)

def open_context_menu(self, point):
    context_menu = QtGui.QMenu()
    ix = self.ui_table.indexAt(point)
    val = ix.data()
    context_menu.addAction("Search: {}".format(val))
    action = context_menu.exec_(self.ui_table.mapToGlobal(point))
    if action:
        self.ui_search.setText(val)
