wxpython:将一个列表框中的多个字符串插入另一个列表框

当我点击timezone1列表框中zone_list的其中一个选项时,我想在time_zones2列表框中插入该字符串,如果我之后选择了另一个选项,我想将第二个选项添加到第二行of timezones2列表框。然后,当我点击之前我在time_zone2列表框中选择的一个选项时,我想删除该选项。

这就是我想要做的: listbox1单击一个选项 - >在listbox2中插入该选项 listbox2点击一个选项 - >从listbox2中删除该选项

看看我在下面做了什么:

import wx

from time import *

class MyFrame(wx.Frame):
    def __init__(self, parent, id, title):
        wx.Frame.__init__(self, parent, id, title, wx.DefaultPosition, (550, 350))

        zone_list = ['CET', 'GMT', 'MSK', 'EST', 'PST', 'EDT']


        panel = wx.Panel(self, -1)
        self.time_zones = wx.ListBox(panel, -1, (10,100), (170, 130), zone_list, wx.LB_SINGLE)
        self.time_zones.SetSelection(0)

        self.time_zones2 = wx.ListBox(panel, -1, (10,200), (170, 400), '',wx.LB_SINGLE)

        self.Bind(wx.EVT_LISTBOX, self.OnSelect)

    def OnSelect(self, event):

        index = event.GetSelection()
        time_zone = self.time_zones.GetString(index)


        self.time_zones2.Set(time_zone)

class MyApp(wx.App):
    def OnInit(self):
        frame = MyFrame(None, -1, 'listbox.py')
        frame.Centre()
        frame.Show(True)
        return True

app = MyApp(0)
app.MainLoop()

我拿了你的代码并添加了你需要的东西。请记住,wx.ListBox.Set(items)需要一个项列表,因此当您传递一个字符串时,它会将字符串中的每个字符视为一个单独的项。

import wx

from time import *

class MyFrame(wx.Frame):
    def __init__(self, parent, id, title):
        wx.Frame.__init__(self, parent, id, title, wx.DefaultPosition, (550, 350))
        self.second_zones = []
        zone_list = ['CET', 'GMT', 'MSK', 'EST', 'PST', 'EDT']


        panel = wx.Panel(self, -1)
        self.time_zones = wx.ListBox(panel, -1, (10,100), (170, 130), zone_list, wx.LB_SINGLE)
        self.time_zones.SetSelection(0)

        self.time_zones2 = wx.ListBox(panel, -1, (10,200), (170, 400), '',wx.LB_SINGLE)

        self.Bind(wx.EVT_LISTBOX, self.OnSelectFirst, self.time_zones)
        self.Bind(wx.EVT_LISTBOX, self.OnSelectSecond, self.time_zones2)


    def OnSelectFirst(self, event):
        index = event.GetSelection()
        time_zone = str(self.time_zones.GetString(index))
        self.second_zones.append(time_zone)
        self.time_zones2.Set(self.second_zones)


    def OnSelectSecond(self, event):
        index = event.GetSelection()
        time_zone = str(self.time_zones2.GetString(index))
        self.second_zones.remove(time_zone)
        self.time_zones2.Set(self.second_zones)        


class MyApp(wx.App):
    def OnInit(self):
        frame = MyFrame(None, -1, 'listbox.py')
        frame.Centre()
        frame.Show(True)
        return True

app = MyApp(0)
app.MainLoop()
