I like wxPython a lot more than the other gui tooltkits i’ve tried. I’m finding it really easy to keep it from getting cluttered, and it’s easy to pick up and run with, but there are examples like this one below that i’ve seen in various forms all over the place that I think are a waste of time. Why would you have an application that has nothing but a menu bar? You wouldn’t, so doesn’t it make sense to get the confusing parts of gui coding out of the way? Namely, layout and events. These two concepts need to be focused on, without all the extra effects. You can add fancy font changes and other junk later. But for now, It only serves to confuse a noob.

This is dumb.

#!/bin/env python

import wx

class wtfno (wx.Frame):
    def __init__(self, parent, id, title, size):
        wx.Frame.__init__(self, parent, id, title=title, size=size)
        menubar = wx.MenuBar()

	file = wx.Menu()
        menubar.Append(file, '&File')
        help = wx.Menu()
        menubar.Append(help, '&Help')

        self.SetMenuBar(menubar)
        self.Centre()
        self.Show(True)

app = wx.App(0)
wtfno(None, -1, 'Stupid Demo', (250,250))
app.MainLoop()

There, Isn’t this better?

class myFrame (wx.Frame):
    def __init__(self, parent, id, title, size):
        wx.Frame.__init__(self, parent, id, title, size)
        panel = wx.Panel(self, -1)

        # Vertical Sizer (vbox) will contain a few horizontal sizers
        vbox = wx.BoxSizer(wx.VERTICAL)

        # These horizontal sizers will go in the vertical sizer (vbox)
        hbox1 = wx.BoxSizer(wx.HORIZONTAL)
        st1 = wx.StaticText(panel, -1, 'Subject')
        hbox1.Add(st1, 0, wx.RIGHT, 8)
        tc = wx.TextCtrl(panel, -1)
        hbox1.Add(tc, 1)

        vbox.Add(hbox1, 0, wx.EXPAND|wx.LEFT|wx.RIGHT|wx.TOP, 10)

        vbox.Add((-1, 10))
        hbox2 = wx.BoxSizer(wx.HORIZONTAL)
        st2 = wx.StaticText(panel, -1, 'Body')
        hbox2.Add(st2, 0)

        vbox.Add(hbox2, 0, wx.LEFT|wx.TOP, 10)

        vbox.Add((-1, 10))
        hbox3 = wx.BoxSizer(wx.HORIZONTAL)
        tc2 = wx.TextCtrl(panel, -1, style=wx.TE_MULTILINE)
        hbox3.Add(tc2, 1, wx.EXPAND)

        vbox.Add(hbox3, 1, wx.LEFT|wx.RIGHT|wx.EXPAND, 10)

        # Make it all happen
        panel.SetSizer(vbox)
        self.Centre()
        self.Show(True)

app = wx.App()
myFrame(None, -1, 'Rootninja.com', (250,250))
app.MainLoop()

And event demos should include different types of events, without a lot of fancy dancy decoration.

    def onWidgetSetup(self, widget, event, handler, sizer):
        widget.Bind(event, handler)
        sizer.Add(widget, 0, wx.ALL, 5)
        return widget

    def onButtonKeyEvent(self, event):
        keycode = event.GetKeyCode()
        if keycode == wx.WXK_SPACE:
            print "The spacebar was pressed"
        event.Skip()
