Python 在Wx TXTCRL中获取错误

我正在马来亚拉姆语文本编辑器上工作。我需要在WxPython中单击按钮时使用文本控件加粗选定的文本。工作环境是Ubuntu10.04和Wxpython2.8

这是我的密码：

import wx

class TestFrame(wx.Frame):
    def __init__(self, *args, **kwargs):
        super(TestFrame, self).__init__(*args, **kwargs)

        panel = wx.Panel(self)

        text = 'Highlight some text and then click the button below'

        self.textctrl = wx.TextCtrl(panel, value=text, style=wx.TE_RICH2,
                                    size=(300, -1))

        btn = wx.Button(panel, wx.ID_BOLD)
        btn.Bind(wx.EVT_BUTTON, self.on_bold)

        pSizer = wx.BoxSizer(wx.VERTICAL)
        pSizer.Add(self.textctrl, 0, wx.ALL, 5)
        pSizer.Add(btn, 0, wx.ALL, 5)
        panel.SetSizer(pSizer)

        vSizer = wx.BoxSizer(wx.VERTICAL)
        vSizer.Add(panel, 1, wx.EXPAND)
        self.SetSizer(vSizer)
        self.Layout()

    def on_bold(self, event):
        start, end = self.textctrl.GetSelection()
        font = self.textctrl.GetFont()
        font.MakeBold()
        text_attr = wx.TextAttr(self.textctrl.ForegroundColour,
                                self.textctrl.BackgroundColour, font)
        self.textctrl.SetStyle(start, end, text_attr)


if __name__ == '__main__':
    wxapp = wx.App(False)
    testFrame = TestFrame(None)
    testFrame.Show()
    wxapp.MainLoop()

错误

Traceback (most recent call last):
  File "C:/Python27/gdg", line 29, in on_bold
    font.MakeBold()
AttributeError: 'Font' object has no attribute 'MakeBold'

---

谢谢@Yoriz，但得到了错误回溯（最近一次调用是最后一次）：文件“C:/Python27/gdg”，第29行，on_bold font.MakeBold（）AttributeError:'Font'对象没有属性'MakeBold'，我正在使用wxpython 2.9.4.0版，因此您必须升级您的版本，或者了解2.8版使用了什么，而不是MakeBold ps看起来这可能是解决方法-

import wx

    def __init__(self, *args, **kwargs):
        super(TestFrame, self).__init__(*args, **kwargs)

        panel = wx.Panel(self)

        text = 'Highlight some text and then click the button below'

        self.textctrl = wx.TextCtrl(panel, value=text, style=wx.TE_RICH2,
                                    size=(300, -1))

        btn = wx.Button(panel, wx.ID_BOLD)
        btn.Bind(wx.EVT_BUTTON, self.on_bold)

        pSizer = wx.BoxSizer(wx.VERTICAL)
        pSizer.Add(self.textctrl, 0, wx.ALL, 5)
        pSizer.Add(btn, 0, wx.ALL, 5)
        panel.SetSizer(pSizer)

        vSizer = wx.BoxSizer(wx.VERTICAL)
        vSizer.Add(panel, 1, wx.EXPAND)
        self.SetSizer(vSizer)
        self.Layout()

    def on_bold(self, event):
        start, end = self.textctrl.GetSelection()
        font = self.textctrl.GetFont()
        font.MakeBold()
        text_attr = wx.TextAttr(self.textctrl.ForegroundColour,
                                self.textctrl.BackgroundColour, font)
        self.textctrl.SetStyle(start, end, text_attr)
