Question

I have a weird problem. I can only copy the text once. If I press clear and type again the text disappears and I have to restart it. Where have I messed up?

Now the questions:

1) Can I bind the clear function to the “Encrypt/Decrypt” so that each time I want to type again it
clears automatically?

2)How can I copy the output to the clipboard with a button?

Code(Pretty messy):

import wx

class main(wx.Frame):



    def __init__(self,parent,id):
        wx.Frame.__init__(self,parent,id,'Title',size=(353,270))

        self.panel=wx.Panel(self)

        button1=wx.Button(self.panel,label='Encrypt\Decrypt',pos=(10,10),size=(-1,60))
        button2=wx.Button(self.panel,label='Current PIN',        pos=(150,10),size=(-1,60))
        button3=wx.Button(self.panel,label='Change PIN',           pos=(250,10),size=(-1,60))
        button4= wx.Button(self.panel,label='Reset',pos=(10,200),size=(-1,20))

        self.Bind(wx.EVT_BUTTON, self.option1, button1)
        self.Bind(wx.EVT_BUTTON, self.option2, button2)
        self.Bind(wx.EVT_BUTTON, self.option3, button3)
        self.Bind(wx.EVT_BUTTON, self.clear,  button4)

        self.Bind(wx.EVT_CLOSE,self.closewindow)
        self.pin='ABC'

    def option1(self,event):
        box1=wx.TextEntryDialog(None,'Type...','','...here')
        if box1.ShowModal()==wx.ID_OK:
            answer1=box1.GetValue()

        def xor(text, key):
            list = ''
            for char in text:
                for ch in key:
                    char = chr(ord(char) ^ ord(ch))
                list += char
            return list

        msg = xor(answer1, self.pin)
        self.output=wx.TextCtrl(self.panel, -1,msg,pos=(10,80),size=(300, 100), style=wx.TE_MULTILINE|wx.TE_READONLY)
        #output=wx.StaticText(self.panel,-1,msg,(10,80),(260,-1),wx.ALIGN_CENTER)


    def option2(self,event):
        box2=wx.MessageDialog(None,self.pin,'Current PIN',wx.OK)
        answer2=box2.ShowModal()
        box2.Destroy()

    def option3(self,event):
        box3=wx.TextEntryDialog(None,'Type...','','...here')
        if box3.ShowModal()==wx.ID_OK:
            answer3=box3.GetValue()
            self.pin=answer3

    def closewindow(self,event):
        self.Destroy()

    def clear(self,event):
        self.output.Clear()






if __name__=='__main__':
    app=wx.PySimpleApp()
    frame=main(parent=None,id=-1)
    frame.Show()
    app.MainLoop()

Answer 1

Every time you push the button (method option1) you create a new overlapping TextCtrl. You should have created in the constructor and just change the text in the method.

1) Just call self.output.Clear() at the beginning of the option1 method.

2)

clipdata = wx.TextDataObject()
clipdata.SetText("Text here")
wx.TheClipboard.Open()
wx.TheClipboard.SetData(clipdata)
wx.TheClipboard.Close()
