如何指定我的事件使用另一个处理程序wxPython

Question

我正在构建一个工具来从目录生成产品代码以获得乐趣。

我有一个事件处理程序的问题，它想不断地调用错误的代码，我不知道为什么。

import wx 
class MyToolMainScreen(wx.Frame): 

    #---------------------------------------------------------------------- 
    def __init__(self): 
     wx.Frame.__init__(self, None, wx.ID_ANY, "Contrinex Helper") 
     panel = wx.Panel(self, wx.ID_ANY) 

     ##initialize the variables we need here. 
     self.sensorTypeSelection = "" 
     self.connectionSelection = "" 
     self.seriesSelection = "" 
     self.outputSelection = "" 
     self.housingSizeSelection = "" 
     self.housingTypeSelection = "" 
     self.outputTypeSelection = "" 

     global stldict 
     global cldict 
     global sldict 
     global oldict 
     global hsldict 
     global otldict 

     ###Lists to hold our combobox list options 
     sensorTypeList = ["Conventional","High-temperature"] 
     connectionList = ["Cable","Connector","Cable w/ moulded connector"] 
     seriesList = ["500/520 (Extra-Distance)","600/620 (Classics)","700 (Full-inox)","Embeddable/Quasi-embeddable","Non-embeddable","Increased Operating Distance, (Quasi-)embeddable","Increased Operating Distance, Non-embeddable"] 
     outputList = ["NPN N.O.","NPN N.C.","PNP N.O.","PNP N.C."] 
     housingSizeList = ["Threaded M4","Threaded M5","Threaded M8","Threaded M12","Threaded M18","Threaded M30","Threaded M50","Smooth 0 3mm","Smooth 0 4mm","Smooth 0 6.5mm","Smooth 0 8mm","Smooth 5x5mm","Smooth 8x8mm","Smooth 40x40mm","Smooth 40x120mm","Smooth 60x80mm","Smooth 80x100mm"] 
     housingTypeList = ["Threaded cylindrical housing","Rectangular Housing","Smooth cylindrical housing"] 
     outputTypeList = ["2-wire DC - N.O./Namur","2-wire DC - N.C.","2-wire AC/DC - N.O.","2-wire N.C."] 

     ###Dictionaries to hold the key:value pairs I will use to concatenate the string before it is placed in the spreadsheet 
     stldict = {"Conventional":"A","High-temperature":"H"} 
     cldict = {"Cable":"D","Connector":"S","Cable w/ moulded connector":"V"} 
     sldict = {"500/520 (Extra-Distance)":"5","600/620 (Classics)":"6","700 (Full-inox)":"7","Embeddable/Quasi-embeddable":"0","Non-embeddable":"1","Increased Operating Distance (Quasi-)embeddable":"2","Increased Operating Distance, Non-embeddable":"3"} 
     oldict = {"NPN N.O.":"1","NPN N.C.":"2","PNP N.O.":"3","PNP N.C.":"4"} 
     hsldict = {"Threaded M4":"4","Threaded M5":"5","Threaded M8":"8","Threaded M12":"12","Threaded M18":"18","Threaded M30":"30","Threaded M50":"50","Smooth 0 3mm":"3","Smooth 0 4mm":"4","Smooth 0 6.5mm":"65","Smooth 0 8mm":"80","Smooth 5x5mm":"5","Smooth 8x8mm":"8","Smooth 40x40mm":"44","Smooth 40x120mm":"40","Smooth 60x80mm":"60","Smooth 80x100mm":"80"} 
     htldict = {"Threaded cylindrical housing":"M","Rectangular Housing":"C","Smooth cylindrical housing":"O"} 
     otldict = {"2-wire DC - N.O./Namur":"5","2-wire DC - N.C.":"6","2-wire AC/DC - N.O.":"7","2-wire N.C.":"8"} 

     self.combo = wx.ComboBox(panel, choices=sensorTypeList) 
     self.combo2 = wx.ComboBox(panel, choices=connectionList) 
     self.combo3 = wx.ComboBox(panel, choices=seriesList) 
     self.combo4 = wx.ComboBox(panel, choices=outputList) 
     self.combo5 = wx.ComboBox(panel, choices=housingSizeList) 
     self.combo6 = wx.ComboBox(panel, choices=housingTypeList) 
     self.combo7 = wx.ComboBox(panel, choices=outputTypeList) 

     self.combo.Bind(wx.EVT_COMBOBOX, self.onCombo) 
     self.combo2.Bind(wx.EVT_COMBOBOX, self.onCombo2) 
     self.combo3.Bind(wx.EVT_COMBOBOX, self.onCombo3) 
     self.combo4.Bind(wx.EVT_COMBOBOX, self.onCombo4) 
     self.combo5.Bind(wx.EVT_COMBOBOX, self.onCombo5) 
     self.combo6.Bind(wx.EVT_COMBOBOX, self.onCombo6) 
     self.combo7.Bind(wx.EVT_COMBOBOX, self.onCombo7) 

     ##Layout goes here... v0.1 v2 will have 2 columns and custom graphics all around 
     sizer = wx.BoxSizer(wx.VERTICAL) 
     sizer.Add(self.combo) 
     sizer.Add(self.combo2) 
     sizer.Add(self.combo3) 
     sizer.Add(self.combo4) 
     sizer.Add(self.combo5) 
     sizer.Add(self.combo6) 
     sizer.Add(self.combo7) 

     panel.SetSizer(sizer) 

    #---------------------------------------------------------------------- 
    #Event handlers go here, what happens after selection 
    def onCombo(self, event): 
     """ 
     """ 
     self.censorTypeSelection = self.combo.GetValue() 
     value = stldict[self.censorTypeSelection] 
     ### next step is to add this to a spreadsheet that will be at the bottom of the sizer. for now I'll just print and set the variable to concatenate at the end 
     print value 


    def onCombo2(self, event): 
     """ 
     """ 
     self.connectionSelection = self.combo.GetValue() 
     value2 = cldict[self.connectionSelection] 

     print value2 

    def onCombo3(self, event): 
     """ 
     """ 
     self.seriesSelection = self.combo.GetValue() 
     value3 = sldict[self.seriesSelection] 

     print value3 

    def onCombo4(self, event): 
     """ 
     """ 
     self.outputSelection = self.combo.GetValue() 
     value4 = oldict[self.outputSelection] 

     print value4 

    def onCombo5(self, event): 
     """ 
     """ 
     self.housingSizeSelection = self.combo.GetValue() 
     value5 = hsldict[self.housingSizeSelection] 

     print value5 

    def onCombo6(self, event): 
     """ 
     """ 
     self.housingTypeSelection = self.combo.GetValue() 
     value6 = htldict[self.housingTypeSelection] 

     print value6 

    def onCombo7(self, event): 
     """ 
     """ 
     self.outputTypeSelection = self.combo.GetValue() 
     value7 = otldict[self.outputTypeSelection] 

     print value7 
#---------------------------------------------------------------------- 
# Run the program 
if __name__ == "__main__": 
    app = wx.App(False) 
    frame = MyToolMainScreen().Show() 
    app.MainLoop() 

当我运行该程序，并选择我的第一个下拉框，它打印预期的输出，但是当我选择下面的下拉框，好像一遍又一遍地尝试，即使我让他们定义的第一个事件处理程序不同。有没有人遇到过这个问题？你怎么修好它的？

Answer 1

def onCombo6(self, event): 
     """ 
     """ 
     self.housingTypeSelection = self.combo.GetValue() #<- this line is wrong 
     value6 = htldict[self.housingTypeSelection] 

     print value6 

您时刻self.combo（您创建的第一个组合框）的价值......你需要得到的self.comboN，处理程序相匹配的价值...

这本来是很容易通过在几个不同的处理程序中添加一个简单的打印（或在调试模式下运行并逐步通过）来诊断
