WxPita is a a wrapper library for wxPython, which is itself a wrapper library for the wxWidgets cross-platform GUI framework.

WxPita has two main goals:

• Allow the structure of your layout code to correspond more closely to the structure of your GUI
• Allow event callbacks to be bound and defined in a single step

By accomplishing these two goals, wxPita lets you write simpler, more maintainable GUI code.

Let's take a look at a simple example:

The code for this example:

from wxpita import *
import time

f = SizedFrame [
    Button(name='btn1', label='Button 1'),
    Button(name='btn2', label='Button 2'),
    TextCtrl(name='textc', style='te_multiline', expand=True, proportion=1),
]

@f.btn1.button_clicked
@f.btn2.button_clicked
def _(evt):
    text = 'You clicked on "%s" at %s\n' % (
        evt.EventObject.GetLabel(), time.ctime())
    
    f.textc.AppendText(text)

f.Show("A Simple WxPita Example", size=(400,250))

Compare with the equivalent code, written using wxPython:

import wx
import wxaddons.sized_controls as sc
import time

app = wx.PySimpleApp()
frame = sc.SizedFrame(None, title="A Simple WxPython Example")
panel = frame.GetContentsPane()

btn1 = wx.Button(panel, label='Button 1')

btn2 = wx.Button(panel, label='Button 2')

textc = wx.TextCtrl(panel, style=wx.TE_MULTILINE)
textc.SetSizerProps(expand=True, proportion=1)

def onclick(evt):
    text = 'You clicked on "%s" at %s\n' % (
        evt.EventObject.GetLabel(), time.ctime())
    
    textc.AppendText(text)

btn1.Bind(wx.EVT_BUTTON, onclick)
btn2.Bind(wx.EVT_BUTTON, onclick)

frame.Show()
app.MainLoop()
