我有一个水平的boxSizer，其中我添加了2个图片(StaticBitmap)。

我该如何隐藏这个筛子，使它下面的筛子出现？下面是代码

import wx
import wx.lib
import wx.lib.scrolledpanel
import wx.lib.filebrowsebutton

class MyFrame(wx.Frame):
    def __init__(self, *args, **kwds):
        #First retrieve the screen size of the device
        screenSize = wx.DisplaySize()
        screenWidth = screenSize[0]
        screenHeight = screenSize[1]
        # begin wxGlade: MyFrame.__init__
        kwds["style"] = kwds.get("style", 0) | wx.DEFAULT_FRAME_STYLE
        wx.Frame.__init__(self, *args, **kwds)
        # self.SetSize((1200, 650))
        self.SetTitle("Test")
        self.Maximize(True)

        #self.SetForegroundColour(wx.WHITE)
        #self.SetBackgroundColour(wx.Colour(204, 0, 0))

        sizer_1 = wx.BoxSizer(wx.VERTICAL)

        self.nb = wx.Notebook(self, wx.ID_ANY)
        # self.nb.SetFocus()
        sizer_1.Add(self.nb, 1, wx.EXPAND, 0)


        self.nbFlash = wx.Panel(self.nb, wx.ID_ANY)
        self.nb.AddPage(self.nbFlash, "Demo")

        sizer_4 = wx.BoxSizer(wx.VERTICAL)

        label_10 = wx.StaticText(self.nbFlash, wx.ID_ANY, "Images")

        label_10.SetFont(wx.Font(12, wx.FONTFAMILY_SWISS, wx.FONTSTYLE_NORMAL, wx.FONTWEIGHT_BOLD, 0, "Arial"))
        sizer_4.Add(label_10, 1, wx.ALIGN_CENTER_HORIZONTAL, 0)

        # sizer_4.Add((10,10), 0, 0, 0)

        sizer_29 = wx.BoxSizer(wx.HORIZONTAL)
        sizer_4.Add(sizer_29, 6, wx.EXPAND, 0)

        img1 = wx.Image("Any image path", wx.BITMAP_TYPE_ANY)
        w = img1.GetWidth()
        h = img1.GetHeight()
        w = w*0.5
        h = h*0.5
        img1 = img1.Scale(w,h)
        bitmap_2 = wx.StaticBitmap(self.nbFlash, wx.ID_ANY, wx.Bitmap(img1))
        sizer_29.Add(bitmap_2, 1, wx.EXPAND, 0)

        img2 = wx.Image("Any image path", wx.BITMAP_TYPE_ANY)
        w = img2.GetWidth()
        h = img2.GetHeight()
        w = w*0.5
        h = h*0.5
        img2 = img2.Scale(w,h)
        bitmap_3 = wx.StaticBitmap(self.nbFlash, wx.ID_ANY, wx.Bitmap(img2))
        sizer_29.Add(bitmap_3, 1, wx.EXPAND, 0)


        sizer_5 = wx.BoxSizer(wx.HORIZONTAL)
        sizer_4.Add(sizer_5, 3, wx.EXPAND, 0)


        ##Bin File, COM Port
        sizer_5_1 = wx.BoxSizer(wx.VERTICAL)
        sizer_5.Add(sizer_5_1, 1, wx.LEFT, 20)

        label_13 = wx.StaticText(self.nbFlash, wx.ID_ANY, "Upload")
        label_13.SetFont(wx.Font(12, wx.FONTFAMILY_SWISS, wx.FONTSTYLE_NORMAL, wx.FONTWEIGHT_BOLD, 0, "Arial"))
        sizer_5_1.Add(label_13, 0, wx.ALIGN_CENTER_HORIZONTAL, 0)

        sizer_5_1.Add((0,0), 1, 0, 0)

        self.fbb1 = wx.FilePickerCtrl(self.nbFlash, message="Choose an Image")
        sizer_5_1.Add(self.fbb1, 0, wx.ALIGN_CENTER_HORIZONTAL, 20)

        sizer_5_1.Add((30,30), 1, 0, 0)
        
        label_14 = wx.StaticText(self.nbFlash, wx.ID_ANY, "Add")
        label_14.SetFont(wx.Font(12, wx.FONTFAMILY_SWISS, wx.FONTSTYLE_NORMAL, wx.FONTWEIGHT_BOLD, 0, "Arial"))
        sizer_5_1.Add(label_14, 0, wx.ALIGN_CENTER_HORIZONTAL, 0)

        sizer_5_1.Add((0,0), 1, 0, 0)

        self.text = wx.TextCtrl(self.nbFlash, wx.ID_ANY, style = wx.TE_PROCESS_ENTER)

    
        sizer_5_1.Add(self.text, 0, wx.ALIGN_CENTER_HORIZONTAL, 0)

        sizer_5_1.Add((0,0), 1, wx.ALIGN_CENTER_HORIZONTAL, 0)


        self.nbFlash.SetSizer(sizer_4)
        self.SetSizer(sizer_1)

        self.Layout()

class MyApp(wx.App):
    def OnInit(self):
        self.frame = MyFrame(None, wx.ID_ANY, "")
        self.SetTopWindow(self.frame)
        self.frame.Show()
        return True

# end of class MyApp

if __name__ == "__main__":
    app = MyApp(0)
    app.MainLoop()

我可以隐藏图像，但它仍然保持空间的sizer。现在不是图像，而是空白处。

请提出一些解决办法。

您可以沿着在sizer中获取小部件的子代和孙辈的路线充电，单独处理它们，也可以使用Sizer的ShowItems方法。

我添加了一个隐藏按钮，作为你的例子，令人费解的是，缺少了你想要测试的方法。

注释:为非最大化窗口调整的示例代码
