Question

请注意：这不是wxPython: displaying multiple widgets in same frame的重复，这是对问题的疑问。

好的，我已经在同一帧上有一个Notebook和一个Button。源代码：

import wx
import wx.lib.sheet as sheet

class MySheet(sheet.CSheet):
    def __init__(self, parent):
        sheet.CSheet.__init__(self, parent)

        self.SetLabelBackgroundColour('#CCFF66')
        self.SetNumberRows(50)
        self.SetNumberCols(50)


class Notebook(wx.Frame):
    def __init__(self, parent, id, title):
        wx.Frame.__init__(self, parent, id, title, size=(600, 600))
        menubar = wx.MenuBar()
        file = wx.Menu()
        file.Append(101, 'Quit', '' )
        menubar.Append(file, "&File")
        self.SetMenuBar(menubar)
        wx.EVT_MENU(self, 101, self.OnQuit)
        nb = wx.Notebook(self, -1, style=wx.NB_BOTTOM)
        self.sheet1 = MySheet(nb)
        self.sheet2 = MySheet(nb)
        self.sheet3 = MySheet(nb)
        nb.AddPage(self.sheet1, "Sheet1")
        nb.AddPage(self.sheet2, "Sheet2")
        nb.AddPage(self.sheet3, "Sheet3")
        self.sheet1.SetFocus()
        self.StatusBar()



        self.button1 = wx.Button(self, -1, label = "Ok")
        #self.button2 = wx.Button(self, -1, label = "Not Ok")

        sizerV = wx.BoxSizer(wx.VERTICAL)

        # add notebook first, with size factor 2:
        sizerV.Add(nb, 5)
        # then text, size factor 1, maximized
        sizerV.Add(self.button1, 1, wx.EXPAND)

        # assign the sizer to Frame:
        self.SetSizerAndFit(sizerV)

def StatusBar(self):
    self.statusbar = self.CreateStatusBar()

def OnQuit(self, event):
    self.Close()


class MyFrame(wx.Frame):
    def __init__(self, parent, id, title):
        wx.Frame.__init__(self, parent, id, title, wx.DefaultPosition, wx.Size(450, 400))
        self.text = wx.TextCtrl(self, -1, style = wx.TE_MULTILINE)
        self.Center()

class MyApp(wx.App):
    def OnInit(self):
        frame = Notebook(None, -1, 'Pandel.py')
        frame.Show(True)
        frame.Center()
        frame2 = MyFrame(None, -1, '')
        self.SetTopWindow(frame2)
        return True


app = MyApp(0)
app.MainLoop()

输出： sample output

但我想要两个彼此相邻的按钮，而不是屏幕上的那个大按钮。

那就是我想一起使用wx.HORIZONTAL和WX.VERTICAL sizer。我该怎么做？

考虑尺寸和面板等的最佳方法是它们是容器。对于复杂的布局，我建议抓一支铅笔和一张纸，勾勒出你的布局。然后在小部件周围绘制框。那些盒子是你的尺寸（或者有时它们是面板和尺寸）。无论如何，你会很快意识到所有的绘图都可以将盒子嵌套在一起。这是BoxSizers的关键。你可以嵌套他们！它可能会让人感到困惑，但是如果你保持你的代码非常清晰和精心设计，它就会很好用。

无论如何我的散文，这是代码：

import wx
import wx.lib.sheet as sheet

class MySheet(sheet.CSheet):
    def __init__(self, parent):
        sheet.CSheet.__init__(self, parent)

        self.SetLabelBackgroundColour('#CCFF66')
        self.SetNumberRows(50)
        self.SetNumberCols(50)


class Notebook(wx.Frame):
    def __init__(self, parent, id, title):
        wx.Frame.__init__(self, parent, id, title, size=(600, 600))
        menubar = wx.MenuBar()
        file = wx.Menu()
        file.Append(101, 'Quit', '' )
        menubar.Append(file, "&File")
        self.SetMenuBar(menubar)
        wx.EVT_MENU(self, 101, self.OnQuit)
        nb = wx.Notebook(self, -1, style=wx.NB_BOTTOM)
        self.sheet1 = MySheet(nb)
        self.sheet2 = MySheet(nb)
        self.sheet3 = MySheet(nb)
        nb.AddPage(self.sheet1, "Sheet1")
        nb.AddPage(self.sheet2, "Sheet2")
        nb.AddPage(self.sheet3, "Sheet3")
        self.sheet1.SetFocus()
        self.StatusBar()



        self.button1 = wx.Button(self, -1, label = "Ok")
        self.button2 = wx.Button(self, -1, label = "Not Ok")

        sizerV = wx.BoxSizer(wx.VERTICAL)
        sizerH = wx.BoxSizer(wx.HORIZONTAL)

        # add notebook first, with size factor 2:
        sizerV.Add(nb, 5)
        # then text, size factor 1, maximized
        sizerH.Add(self.button1, 1, wx.EXPAND)
        sizerH.Add(self.button2, 1, wx.EXPAND)
        sizerV.Add(sizerH, 1, wx.ALL|wx.EXPAND, 5)

        # assign the sizer to Frame:
        self.SetSizerAndFit(sizerV)

    def StatusBar(self):
        self.statusbar = self.CreateStatusBar()

    def OnQuit(self, event):
        self.Close()


class MyFrame(wx.Frame):
    def __init__(self, parent, id, title):
        wx.Frame.__init__(self, parent, id, title, wx.DefaultPosition, wx.Size(450, 400))
        self.text = wx.TextCtrl(self, -1, style = wx.TE_MULTILINE)
        self.Center()

class MyApp(wx.App):
    def OnInit(self):
        frame = Notebook(None, -1, 'Pandel.py')
        frame.Show(True)
        frame.Center()
        frame2 = MyFrame(None, -1, '')
        self.SetTopWindow(frame2)
        return True


app = MyApp(0)
app.MainLoop()

如何在Wxpython中使用sizer将多个小部件放在同一个框架中？
