Welcome folks today in this blog post we will be doing copy to clipboard text using textctrl widget and pasting it in another panel using listctrl widget in gui desktop app in python. All the full source code of the application is given below.

Get Started

In order to get started you need to install the below library using the pip command as shown below

pip install wxpython

After installing this library you need to make an app.py file and copy paste the following code

app.py

import wx

t1_text = """\
The whole contents of this control
will be placed in the system's
clipboard when you click the copy
button below.
"""

t2_text = """\
If the clipboard contains a text
data object then it will be placed
in this control when you click
the paste button below.  Try
copying to and pasting from
other applications too!
"""

class MyFrame(wx.Frame):
    def __init__(self):
        wx.Frame.__init__(self, None, title="Clipboard",
                          size=(500,300))
        p = wx.Panel(self)

        # create the controls
        self.t1 = wx.TextCtrl(p, -1, t1_text,
                              style=wx.TE_MULTILINE|wx.HSCROLL)
        self.t2 = wx.TextCtrl(p, -1, t2_text,
                              style=wx.TE_MULTILINE|wx.HSCROLL)
        copy = wx.Button(p, -1, "Copy")
        paste = wx.Button(p, -1, "Paste")

        # setup the layout with sizers
        fgs = wx.FlexGridSizer(2, 2, 5, 5)
        fgs.AddGrowableRow(0)
        fgs.AddGrowableCol(0)
        fgs.AddGrowableCol(1)
        fgs.Add(self.t1, 0, wx.EXPAND)
        fgs.Add(self.t2, 0, wx.EXPAND)
        fgs.Add(copy, 0, wx.EXPAND)
        fgs.Add(paste, 0, wx.EXPAND)
        border = wx.BoxSizer()
        border.Add(fgs, 1, wx.EXPAND|wx.ALL, 5)
        p.SetSizer(border)

        # Bind events
        self.Bind(wx.EVT_BUTTON, self.OnDoCopy, copy)
        self.Bind(wx.EVT_BUTTON, self.OnDoPaste, paste)

    def OnDoCopy(self, evt):
        data = wx.TextDataObject()
        data.SetText(self.t1.GetValue())
        if wx.TheClipboard.Open():
            wx.TheClipboard.SetData(data)
            wx.TheClipboard.Close()
        else:
            wx.MessageBox("Unable to open the clipboard", "Error")

    def OnDoPaste(self, evt):
        success = False
        data = wx.TextDataObject()
        if wx.TheClipboard.Open():
            success = wx.TheClipboard.GetData(data)
            wx.TheClipboard.Close()

        if success:
            self.t2.SetValue(data.GetText())
        else:
            wx.MessageBox(
                "There is no data in the clipboard in the required format",
                "Error")
    

app = wx.PySimpleApp()
frm = MyFrame()
frm.Show()
app.MainLoop()

If you execute the above python script by typing the below command

python app.py
