Python: Simple HTTP Server on python.

(Repost from old blog)

Python have several modules that help you to achieve your goals. This week, on my spare time that is getting every day more scarce I spend time figuring out how to create a Python Web Server, I was planing to use it over an application that I’m developing on ICT Consulting. At the end I didn’t use it because I didn’t want a “passive” communication, but probably I will use this code on the CRM Desktop application that we use here.

Anyway, this code may be helpful for you too. I found that creating a small web server is really simple, It starts getting bigger as you add functions to that web server, but the basis is quite simple.

import os import cgi import sys from BaseHTTPServer import HTTPServer, BaseHTTPRequestHandler class customHTTPServer(BaseHTTPRequestHandler): def do_GET(self): self.send_response(200) self.send_header('Content-type', 'text/html') self.end_headers() self.wfile.write('<HTML><body>Get!</body></HTML>') return def do_POST(self): global rootnode ctype,pdict = cgi.parse_header(self.headers.getheader('Content-type')) if ctype == 'multipart/form-data': query = cgi.parse_multipart(self.rfile, pdict) self.send_response(301) self.end_headers() self.wfile.write('Post!') def main(): try: server = HTTPServer(('',8080),customHTTPServer) print 'server started at port 8080' server.serve_forever() except KeyboardInterrupt: server.socket.close() if __name__=='__main__': main() read more

Image as background in a Gtk Application.

(Reposted from the old blog)

This time I’m going to talk about putting an image as the application background in Gtk. In Gtk we are used to leave the colors of the application to the theme, but sometimes we will need to use an image as background. I already wrote how to draw a pixbuf in a gtk.DrawingArea (Esp), we could use that, but we will “draw” directly on the widget window instead.

Yes, I said the widget’s window instead the widget itself. You should know that every widget that has been packed in a container has a gtk.gdk.window object and is the responsible for containing your widget. Well, we can draw on that object.

What we need is to create a simple gtk.gdk.Pixbuf and call the gtk.gdk.window.draw_pixbuf method using your widget.window object on the expose-event.

The code should look like this:

#!/usr/bin/env python import gtk def draw_pixbuf(widget, event): path = '/home/markuz/wallpapers/WMwall1024x768.gif' pixbuf = gtk.gdk.pixbuf_new_from_file(path) widget.window.draw_pixbuf(widget.style.bg_gc[gtk.STATE_NORMAL], pixbuf, 0, 0, 0,0) window = gtk.Window() window.set_title('Drawing Test') window.set_size_request(640,480) window.connect('destroy',gtk.main_quit) hbbox = gtk.HButtonBox() window.add(hbbox) hbbox.connect('expose-event', draw_pixbuf) button = gtk.Button('Press Me!') hbbox.pack_start(button, True, False, 10) window.show_all() gtk.main() read more
