我是 python GUI 的新手，wxpython也是。現在我面臨以下問題。這里的代碼是import wxclass Example(wx.Frame): def __init__(self, parent, title): super(Example, self).__init__(parent, title=title) self.InitUI() self.Centre() self.Show() def InitUI(self): panel = wx.Panel(self) sizer = wx.GridBagSizer(0, 0) text = wx.StaticText(panel, label="Name:") sizer.Add(text, pos=(0, 0), flag=wx.ALL, border=5) tc = wx.TextCtrl(panel) sizer.Add(tc, pos=(0, 1), span=(1, 2), flag=wx.EXPAND | wx.ALL, border=5) text1 = wx.StaticText(panel, label="address") sizer.Add(text1, pos=(1, 0), flag=wx.ALL, border=5) tc1 = wx.TextCtrl(panel, style=wx.TE_MULTILINE) sizer.Add(tc1, pos=(1, 1), span=(1, 3), flag=wx.EXPAND | wx.ALL, border=5) text11 = wx.StaticText(panel, label="address2") sizer.Add(text11, pos=(1, 4), flag=wx.ALL, border=5) tc11 = wx.TextCtrl(panel, style=wx.TE_MULTILINE) sizer.Add(tc11, pos=(1, 5), span=(1, 3), flag=wx.EXPAND | wx.ALL, border=5) text2 = wx.StaticText(panel, label="age") sizer.Add(text2, pos=(2, 0), flag=wx.ALL, border=5) tc2 = wx.TextCtrl(panel) sizer.Add(tc2, pos=(2, 1), flag=wx.ALL, border=5) text3 = wx.StaticText(panel, label="Mob.No") sizer.Add(text3, pos=(2, 2), flag=wx.ALIGN_CENTER | wx.ALL, border=5)這里的結果是讓我感到困惑的是標簽。address2它顯然沒有跨越三列。text11 = wx.StaticText(panel, label="address2")sizer.Add(text11, pos=(1, 4), flag=wx.ALL, border=5)tc11 = wx.TextCtrl(panel, style=wx.TE_MULTILINE)sizer.Add(tc11, pos=(1, 5), span=(1, 3), flag=wx.EXPAND | wx.ALL, border=5)但是address2標簽的代碼與標簽相同，address除了 param pos。有人可以解釋一下。環境：python3.7/wxpython4.0.4（最新）

那3列的定義是什么？
您是否為要使用的第 5,6 和 7 列定義了任何內容sizer？
沒有東西可以使用 sizer 不知道這些列有多大，所以你必須給它一些東西來使用或定義一個空的單元格大小。
import wx
class Example(wx.Frame):
def __init__(self, parent, title):
super(Example, self).__init__(parent, title=title, size=(750,-1))
self.InitUI()
self.Centre()
self.Show()
def InitUI(self):
panel = wx.Panel(self, -1)
sizer = wx.GridBagSizer(0, 7)
text = wx.StaticText(panel, label="Name:")
sizer.Add(text, pos=(0, 0), flag=wx.ALL, border=5)
#
# place some dummy text to give the sizer something to work with
#
# dummy4 = wx.StaticText(panel, label="something")
# sizer.Add(dummy4, pos=(0, 4), flag=wx.ALL, border=5)
# dummy5 = wx.StaticText(panel, label="something")
# sizer.Add(dummy5, pos=(0, 5), flag=wx.ALL, border=5)
# dummy6 = wx.StaticText(panel, label="something")
# sizer.Add(dummy6, pos=(0, 6), flag=wx.ALL, border=5)
# dummy7 = wx.StaticText(panel, label="something")
# sizer.Add(dummy7, pos=(0, 7), flag=wx.ALL, border=5)
#
# or set a cell size for empty cells
#
sizer.SetEmptyCellSize((130,20))
tc = wx.TextCtrl(panel)
sizer.Add(tc, pos=(0, 1), span=(1, 2), flag=wx.EXPAND | wx.ALL, border=5)
text1 = wx.StaticText(panel, label="address")
sizer.Add(text1, pos=(1, 0), flag=wx.ALL, border=5)
tc1 = wx.TextCtrl(panel, style=wx.TE_MULTILINE)
sizer.Add(tc1, pos=(1, 1), span=(1, 3), flag=wx.EXPAND | wx.ALL, border=5)
text11 = wx.StaticText(panel, label="address2")
sizer.Add(text11, pos=(1, 4), flag=wx.ALL, border=5)
tc11 = wx.TextCtrl(panel, style=wx.TE_MULTILINE)
sizer.Add(tc11, pos=(1, 5), span=(1, 3), flag=wx.EXPAND | wx.ALL, border=5)
text2 = wx.StaticText(panel, label="age")
sizer.Add(text2, pos=(2, 0), flag=wx.ALL, border=5)
tc2 = wx.TextCtrl(panel)
sizer.Add(tc2, pos=(2, 1), flag=wx.ALL, border=5)
text3 = wx.StaticText(panel, label="Mob.No")
sizer.Add(text3, pos=(2, 2), flag=wx.ALIGN_CENTER | wx.ALL, border=5)
tc3 = wx.TextCtrl(panel)
sizer.Add(tc3, pos=(2, 3), flag=wx.EXPAND | wx.ALL, border=5)
text4 = wx.StaticText(panel, label="Description")
sizer.Add(text4, pos=(3, 0), flag=wx.ALL, border=5)
tc4 = wx.TextCtrl(panel, style=wx.TE_MULTILINE)
sizer.Add(tc4, pos=(3, 1), span=(1, 3), flag=wx.EXPAND | wx.ALL, border=5)
sizer.AddGrowableRow(3)
buttonOk = wx.Button(panel, label="Ok")
buttonClose = wx.Button(panel, label="Close")
sizer.Add(buttonOk, pos=(4, 2), flag=wx.ALL, border=5)
sizer.Add(buttonClose, pos=(4, 3), flag=wx.ALL, border=5)
panel.SetSizerAndFit(sizer)
app = wx.App()
Example(None, title='GridBag Demo')
app.MainLoop()
ps 如果您只是將地址 2 放在地址 1 下方，則布局可能會更好
