在wxPython 2.8 中，这将导致页面左上角出现单一模糊。
wxPython 2.9 在使用 sizers 时更聪明一些，这就是为什么它似乎有点工作。
首先，您在BoxSizer 中创建一个GridSizer，但不允许它动态扩展（wx.EXPAND）。
其次，您将 sizer 设置为 wx.Notebook 而不是页面（面板），这会将整个布局向下移动并裁剪网格 sizer 中控件/面板的底行，或者将在 @987654327 中完全忽略@ 从而将所有内容移动到左上角。
这应该可以解决问题：
sizer_31 = wx.BoxSizer(wx.VERTICAL) # page (panel) sizer for outer border
gs = wx.GridSizer(0,4,7,7) # content sizer
for i in self.Panel_Others.keys():
gs.Add(self.Panel_Others[i],0,wx.EXPAND|wx.ALL,5)
# + wx.EXPAND: allow the content to fill the 'cells'
# (proportion is ignored here so it can be 0)
sizer_31.Add(gs,1,wx.EXPAND|wx.ALL,5)
# + 1, wx.EXPAND: allow the grid to expand to the main sizer
# which in turn fits to the page
self.Panel3.SetSizer(sizer_31) # set the sizer to page, not the notebook
编辑：以下示例演示如何在 wx.Notebook 页面中动态更新 wx.GridSizer 的内容：
import wx
class MyFrame(wx.Frame):
def __init__(self):
wx.Frame.__init__(self, None, title='wx.Notebook')
# create a wx.Notebook
book = wx.Notebook(self)
# create a new page; wx.Notebook owns the page
# therefore the notebook must be the parent window
page = MyPage(parent=book)
# add the page to the notebook:
book.AddPage(page, 'Page 1')
book.AddPage(MyPage(book),'Page 2')
book.AddPage(MyPage(book),'Page 3')
class MyPage(wx.Panel):
"a page for wx.Notebook"
def __init__(self, parent):
# NOTE: wxPython 2.9.4/winXP may create graphic
# artifacts when more than one page is added. This can
# be avoided by creating the page with a size of (0,0).
# the reason for this is: the page (here a panel) is
# created with the default size and position (upper
# left corner). Once the layout is applied, the page
# is moved to the proper coordinates. However, the
# wx.Notebook is not redrawn so it will leave a black
# spot where the page was moved away from. Alternatively,
# the frame or notebook can be Refresh()ed after the
# frame is shown.
wx.Panel.__init__(self, parent, size=(0,0))
# create sizer to add a border
pageSizer = wx.BoxSizer(wx.VERTICAL)
# create a grid sizer for the content
self.grid = wx.GridSizer(0, 4, 5, 5)
# add the grid sizer to the page sizer:
# to allow the grid to fill the entire page,
# set proportion>0 and add the wx.EXPAND flag.
# the border of 10 is the spacing between the
# page and the cells of the grid
pageSizer.Add(self.grid, 1, wx.EXPAND|wx.ALL, 10)
# set the main sizer:
self.SetSizer(pageSizer)
# add content to the grid
self.GenerateContent()
# DEMO: click any white space on the page to
# generate new content
self.Bind(wx.EVT_LEFT_DOWN, self.GenerateContent)
def GenerateContent(self, event=None):
"dynamically create page content"
# remove all items from the grid and destroy them
# NOTE: if you don't actually create new controls here,
# but use a list of controls created elsewhere (like in
# in your code), do not delete the items! Use:
# deleteWindows=False instead.
self.grid.Clear(deleteWindows=True)
# generate new grid content
for i in range(10):
# the contents are owned by the page,
# therefore the page must be the parent window:
# NOTE: size=(0,0) here is not required but
# eliminates a briefly shown graphic artifact
cell = wx.Panel(self, size=(0,0))
cell.SetBackgroundColour(self.NewColor())
# add the content (cells) to the grid:
# specify the wx.EXPAND flag to fit the
# content to the grid cell
self.grid.Add(cell, flag=wx.EXPAND)
# DEMO: hint text
self.grid.Add(wx.StaticText(self, label=
'Click empty cell to update content ->'),
flag=wx.EXPAND)
# recalculate the layout to move the new contents
# of the grid sizer into place
self.Layout()
col = 0 # DEMO: coloring
def NewColor(self):
self.col = (self.col + 3) % 241
return wx.Colour(0, self.col * 10 % 255, self.col % 255)
app = wx.App(False)
MyFrame().Show()
app.MainLoop()
