Question

单选按钮位于主菜单栏下方的子菜单中。

无法获取在PySide中单击的单选框的值，这在Tkinter中完美运行以及如何在PySide中设置默认单选按钮？

在PySide中的

：在pyside中更改/选择时无法获得单选框的值。这完美地在下面的tkinter

    os.chdir(user+'database')
    dbfiles=glob.glob('ias*.db')    

    #self.var=('ias'+yr+'.db') used to set default radio button? somehow


    self.ag = QActionGroup(self)
    for self.x in dbfiles: #dbfiles is a "list" of 3 databases 
        dbselect = self.ag.addAction(QAction(self.x, self, checkable=True))#how to set default?
        self.menuDatabases.addAction(dbselect)
    self.ag.triggered.connect(self.displaydb)  #need to trigger something else?

def displaydb(self):
    print(self.x) #need to print something else maybe?

在传统知识中;在这里完美地工作更改单选按钮并将数据库名称打印到文本框

    os.chdir(os.path.expanduser('~')+'/Desktop/data/database')
    self.dbfiles=glob.glob('ias*.db')

    self.var=StringVar()
    self.var.set('ias'+str(dte)+'.db')
    for x in self.dbfiles:
        dbfle.add_radiobutton(label=x,variable=self.var, value=x,command=self.sel)

def sel(self):
   selection = "You changed to database: " + str(self.var.get())
   self.b.delete(1.0,END)
   self.b.insert(END,selection)

Answer 1

设置开始时检查的操作之一：

self.ag.actions()[0].setChecked(true) 
#selects first action, or do this at creation time

并更改回调：

def sel(self, action):
    print action.text()
