python - Error when im trying add a column to a ListCtrl in wxPython(4.0.6)

问题描述

Im trying to add a column to a LisCtrl but i cannot

I tried to follow the documentation but i dont know what am i doing wrong

The documentation says : InsertColumn (self, col, heading, format=LIST_FORMAT_LEFT, width=LIST_AUTOSIZE)

(https://docs.wxpython.org/wx.ListCtrl.html#wx.ListCtrl.InsertColumn)

import wx



class View1(wx.Frame):
    def init(self,*args,**kw):
        super(View1, self).init(*args,**kw)


    panel = wx.Panel(self, pos=(0,0), size=(800,700))



    #TITULO
    titulo = wx.StaticText(panel,label="AGENDA DE CONTACTOS",pos=(130,1)) 

    #Creamos Sizer y le agregamos el titulo
    sizer = wx.BoxSizer(wx.VERTICAL)
    sizer.Add(titulo,0,wx.ALIGN_CENTER,0)
    panel.SetSizer(sizer)

    #Texto1 X,Y
    label1 = wx.StaticText(panel,label="Nombre",pos=(70,50))
    field1 = wx.TextCtrl(panel,pos=(200,50), size=(150,20))

    #Texto2 X,Y
    label2 = wx.StaticText(panel,label="Apellido Paterno",pos=(70,90))
    field2 = wx.TextCtrl(panel,pos=(200,90), size=(150,20)) 

    #Texto3 X,Y
    label3 = wx.StaticText(panel,label="Apellido Materno",pos=(70,130))
    field3 = wx.TextCtrl(panel,pos=(200,130), size=(150,20)) 

    #Texto4 X,Y
    label4 = wx.StaticText(panel,label="Teléfono ",pos=(70,170))
    field4 = wx.TextCtrl(panel,pos=(200,170), size=(150,20)) 

    #Texto5 X,Y
    label5 = wx.StaticText(panel,label="Correo",pos=(70,210))
    field5 = wx.TextCtrl(panel,pos=(200,210), size=(150,20)) 

    #Texto6 X,Y
    label6 = wx.StaticText(panel,label="Teléfono",pos=(450,50))
    field6 = wx.TextCtrl(panel,pos=(550,50), size=(150,21)) 

    #Boton Agregar  
    botonAgregar = wx.Button(panel,label="Agregar",pos=(215,245),size=(120,22))

    #Boton eliminar  
    botonEliminar = wx.Button(panel,label="Eliminar",pos=(565,90),size=(120,22))

    #Creamos el ListCtrl para desplegar la información
    tabla = wx.ListCtrl(panel,pos=(25,350),size=(750,250), style=wx.LC_LIST)
    tabla.InsertColumn (self,0, 'NOMBRE', format=wx.LIST_FORMAT_LEFT, width=wx.LIST_AUTOSIZE)

The result in terminal is : TypeError: ListCtrl.InsertColumn(): arguments did not match any overloaded call: overload 1: argument 1 has unexpected type 'View1' overload 2: argument 1 has unexpected type 'View1'

i tried remove the self parameter leaving as tabla.InsertColumn (0, 'NOMBRE', format=wx.LIST_FORMAT_LEFT, width=wx.LIST_AUTOSIZE) , but appears other error : wx._core.wxAssertionError: C++ assertion "InReportView()" failed at /home/vagrant/wxPython-4.0.6/ext/wxWidgets/src/generic/listctrl.cpp(5196) in DoInsertColumn(): can't add column in non report mode

解决方案

正如 Attila Toth 所说，删除self参数。自我自动传递给python中的方法。在这种情况下self是wx.ListCtrl实例，但是您将View1实例作为列号参数传递。如果您仍然对self参数感到困惑，这里有一个很好的解释

更新以解决新问题

第二个错误是不言自明的。ListCtrl使用样式标志wx.LC_REPORT而不是创建wx.LC_LIST
