当我在 timezone1 列表框中单击 zone_list 的一个选项时,我想将该字符串插入 time_zones2 列表框中,如果之后我选择另一个选项,我想将第二个选项添加到第二行timezones2 列表框。然后,当我在 time_zone2 列表框中单击我之前所做的选择之一时,我想删除该选择。
这是我想做的: listbox1 单击一个选项->将该选项插入 listbox2 listbox2 单击一个选项->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()
请您参考如下方法:
我获取了您的代码并添加了您需要的内容。请记住,wx.ListBox.Set(items) 需要一个项目列表,因此当您向它传递单个字符串时,它会将字符串中的每个字符视为一个单独的项目。
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()
