wxpython中文本框里输入的字符串怎么得到？

怎么得到并处理文本框中输入的字符串?

def createTextFields1(self, panel):
        Label1 = "部门"
        Pos1   = (10,10)
        self.createCaptionedText1(panel, Label1, Pos1)
    def createTextFields2(self, panel):
        Label2 = "内容"
        Pos2   = (10,40)
        self.createCaptionedText2(panel, Label2, Pos2)
    def createTextFields3(self, panel):
        Label1 = "时间"
        Pos1   = (10,150)
        self.createCaptionedText1(panel, Label1, Pos1)
    def createCaptionedText1(self, panel, label, pos):
        static = wx.StaticText(panel, wx.NewId(), label, pos)
        static.SetBackgroundColour("White")
        textPos = (pos[0] + 75, pos[1])
        wx.TextCtrl(panel, wx.NewId(), "", size=(200, -1), pos=textPos)
        wx.TE_PROCESS_ENTER
    def createCaptionedText2(self, panel, label, pos):
        static = wx.StaticText(panel, wx.NewId(), label, pos)
        static.SetBackgroundColour("White")
        textPos = (pos[0] + 75, pos[1])
        wx.TextCtrl(panel, wx.NewId(), "", size=(200, 100), pos=textPos,
                    style=wx.TE_MULTILINE)

用如上代码实现文本框，但是想提取用户在其中输入的数据

怎么办啊
