如何使用QComboBox选择在功能

Question

我有下面的代码使用PyQt的，这显示两个QComboBox的，我想用我的应用程序的选择值：

class TACRG(QtGui.QMainWindow, design.Ui_MainWindow): 
    def __init__(self, parent=None): 
     super(TACRG, self).__init__(parent) 
     self.setupUi(self) 

     self.CList.addItems(["A", "B", "C", "D"]) 
     self.connect(self.CList, QtCore.SIGNAL('activated(QString)'), self.c_chosen) 

     self.RList.addItems(["Q1", "Q2", "Q3", "Annual"]) 
     self.connect(self.RList, QtCore.SIGNAL('activated(QString)'), self.r_chosen) 

    def r_chosen(self, text): 
     report_start, report_end = report_period(text) 

    def c_chosen(self, text): 
     accs = get_ucs(text) 

def report_period(r_period): 
    year=date.today().year 
    if r_period == 'Q1': 
     return (str(year)+'0101',str(year)+'0331') 
    elif r_period == 'Q2': 
     return (str(year)+'0401',str(year)+'0630') 
    elif r_period == 'Q3': 
     return (str(year)+'0701',str(year)+'0930') 
    elif r_period == 'Annual': 
     return (str(year-1)+'0101',str(year-1)+'1231') 

def get_ucs(c_name): 
    """DO something"" 
    return """some string""" 

现在我wan't使用返回的值从report_period和get_ucs函数（report_start，report_end，accs）中读取另一个函数，必须在执行这两个函数后调用它。 我该如何做到这一点？

使用self类的数据成员存储值，打电话给你的两个r_chosen和c_chosenother_method并在使用前在other_method检查有效值。

class TACRG(QtGui.QMainWindow, design.Ui_MainWindow): 
    def __init__(self, parent=None): 
     # Your init code 
     self.report_start, self.report_end, self.accs = [None] * 3 

    def r_chosen(self, text): 
     self.report_start, self.report_end = report_period(text) 
     self.other_method() 

    def c_chosen(self, text): 
     self.accs = get_ucs(text) 
     self.other_method() 

    def other_method(self): 
     #validate if your fields have valid values 
     if self.report_start and self.report_end and self.accs: 
      print self.report_start, self.report_end, self.accs 

编辑（其它方法外类）：

class TACRG(QtGui.QMainWindow, design.Ui_MainWindow): 
    def __init__(self, parent=None): 
     # Your init code 
     self.report_start, self.report_end, self.accs = [None] * 3 

    def r_chosen(self, text): 
     self.report_start, self.report_end = report_period(text) 
     other_method(self.report_start, self.report_end, self.accs) 

    def c_chosen(self, text): 
     self.accs = get_ucs(text) 
     other_method(self.report_start, self.report_end, self.accs) 

def other_method(report_start, report_end, accs): 
    #validate if your fields have valid values 
    if report_start and report_end and accs: 
     print report_start, report_end, accs
