无法理解如何从wxpython中的checklistbox获取数据

我试图检查字符串或检查列表中的整数。我似乎无法在任何地方得到它。在下面的代码中,您将看到一堆未注释的代码,这些只是我尝试过的不同方式。我想我会留下它们以防任何人的建议与它有关。我是GUI编程和wx的新手。谢谢你的帮助。

import  wx


class Panel1(wx.Panel):
def __init__(self, parent, log):
    wx.Panel.__init__(self, parent, -1)

    allLoc = ['One', 'Two', 'Three', 'Four']

    wx.StaticText(self, -1, "Choose:", (45, 15))

    citList = wx.CheckListBox(self, -1, (60, 50), wx.DefaultSize, allLoc)

    #self.Bind(wx.EVT_CHECKLISTBOX, self.GetChecks, citList)

    #h = citList.GetChecked()

    #cities = ()

    #v = cities.append(h)
    #print h
    pos = citList.GetPosition().x + citList.GetSize().width + 25
    nextBtn = wx.Button(self, -1, "Next", (pos, 50))
    self.Bind(wx.EVT_BUTTON, wx.EvyRadBox2, nextBtn)

#def GetChecks(self, event):
    #r = citList.GetId()
    #print r

#def printChecks(self, event):
    #l = event.CetCheckStrings()
    #print l

def EvyRadBox2(self, event):
    filepath2 = "c:\\logger2.txt"
    file1 = open(filepath2, 'w')
    file1.write('%d \n' % event.GetChecked())
    file1.close()





app = wx.PySimpleApp()
frame = wx.Frame(None, -1, "Charlie")
Panel1(frame,-1)
frame.Show(1)
app.MainLoop()

************************** EDIT ******************** ************

所以我将代码改为看起来像这样

import wx

checkedItems = []


class citPanel(wx.Panel):
def __init__(self, parent, id):
    wx.Panel.__init__(self, parent, id)
    allLoc = ['One', 'Two', 'Three', 'Four']

    wx.StaticText(self, -1, "Choose:", (45, 15))

    citList = wx.CheckListBox(self, -1, (60, 50), wx.DefaultSize, allLoc)

    checkedItems = [i for i in range(citList.GetCount()) if citList.IsChecked(i)]


class nextButton(wx.Button):
def __init__(self, parent, id, label, pos):
    wx.Button.__init__(self, parent, id, label, pos)




class checkList(wx.Frame):
def __init__(self, parent, id, title):
    wx.Frame.__init__(self, parent, id, title, size=(400, 400))

    panel = citPanel(self, -1)

    nextButton(panel, -1, 'Ok', (275, 50))

    self.Bind(wx.EVT_BUTTON, self.Clicked)

    self.Centre()
    self.Show(True)

def Clicked(self, event):
    print checkedItems
    event.Skip()


app = wx.App()
checkList(None, -1, 'Charlie')
app.MainLoop()

当我首先执行此操作时,当我单击按钮时,它会将未定义的全局名称输入到wxstdout中。我在顶部添加了清单,它首先显示没有,现在它显示一个空列表。,任何帮助,一如既往,提前谢谢

答案 0 :(得分:3)

checkedItems = [i for i in range(citList.GetCount()) if citList.IsChecked(i)]

citList.GetChecked()也应该为您完成任务。 可能问题在于您是否尝试在__init__中获取所选项目?

更新。:您不希望在__init__期间获取已检查的项目 - 用户当时无法检查这些项目。您最好在任何事件处理程序中检查它们,例如wx.EVT_BUTTON

尝试更频繁地写self,例如:

self.citList = wx.CheckListBox(self, -1, (60, 50), wx.DefaultSize, allLoc)
# some code
self.panel = citPanel(self, -1)

并将Clicked更改为:

def Clicked(self, event):
    checkedItems = [i for i in range(self.panel.citList.GetCount()) if self.panel.citList.IsChecked(i)]
    print checkedItems
    event.Skip()

希望这有帮助。
