Question

我无法在wx.Panel中嵌套ScrolledWindow。如果我自己创建一个滚动窗口它似乎工作，但是当我在wx.Panel内创建它并将wx.Panel添加到帧sizer时它不会。有什么我想念的吗？

注意：

        #pa = AScrolledWindow(self) <-- if uncommented this works
        pa = ScrolledWindowHolder(self) # However this does not!

import wx


class ScrolledWindowHolder(wx.Panel):
    def __init__(self, parent):
        super(ScrolledWindowHolder, self).__init__(parent=parent)
        mysizer = wx.GridBagSizer()
        self.myscrolledWindow = AScrolledWindow(self)
        mysizer.Add(self.myscrolledWindow, pos=(0, 0), flag=wx.EXPAND)
        self.SetSizerAndFit(mysizer)


class AScrolledWindow(wx.ScrolledWindow):
    def __init__(self, parent):
        super(AScrolledWindow, self).__init__(parent)
        gb = wx.GridBagSizer()
        self.sizer = gb

        self._labels = []
        for y in xrange(1, 30):
            self._labels.append(wx.StaticText(self, -1, "Label #%d" % (y,)))
            gb.Add(self._labels[-1], (y, 1), (1, 1))

        self.SetSizer(self.sizer)
        self.SetScrollRate(5, 5)
        self.EnableScrolling(True, True)


class TestFrame(wx.Frame):
    def __init__(self):
        wx.Frame.__init__(self, None, -1, 'Programmatic size change')
        sz = wx.BoxSizer(wx.VERTICAL)
        #pa = AScrolledWindow(self)
        pa = ScrolledWindowHolder(self)
        sz.Add(pa, 1, wx.EXPAND)
        self.SetSizer(sz)


def main():
    wxapp = wx.App()
    fr = TestFrame()
    fr.Show(True)
    wxapp.MainLoop()


if __name__ == '__main__':
    main()

wxPython ScrolledWindow在面板中使用时不起作用
