Gtk# in Windows

I’m hacking on my Gtk# app in Windows right now, because Visual Studio is amazing. I
couldn’t seem to get pixbufs to load from relative paths, because I couldn’t figure out what the present working directory is on anything in Windows, so I started fooling with the resource manager.

This is a very cool thing. You can put strings or images or whatever you want in there, then access it from your app as Properties.Resources.Foo. Very nice.

However, if you’re using images then they’re obviously stored as a System.Drawing.Bitmap, and Gtk# wants to deal with things as a Gdk.Pixbuf. So here’s a quick snippet of code to deal with that:

using System;

using System.Drawing;

using System.Drawing.Imaging;

public Gdk.Pixbuf CreateFromResource( Bitmap bitmap ) {

  BitmapData data = bitmap.LockBits( new Rectangle( 0, 0,

                                                    bitmap.Width, bitmap.Height,

                                                    PixelFormat.Format24bppRgb );

  IntPtr scan = data.Scan0;

  int size = bitmap.Width * bitmap.Height * 3;

  byte[] bdata = new byte[ size ];
  Gdk.Pixbuf pixbuf = null;
  unsafe

  {

    byte* p = (byte*)scan;

    for( int i = 0; i 

Monodevelop

So I started testing out Monodevelop for hacking on my resurrected Ludwig van. It’s pretty nice, I think. Obviously it’s pretty far from Visual Studio, but it’s not bad. The big new thing in the latest release is the integration of stetic, the user interface builder.

Maybe I’m retarded, but I just can’t ever seem to save time by using these UI builders. Glade was okay, but so far I can’t figure out how to use stetic in any remotely useful way. In this respect, I don’t feel that Visual Studio is much further along because its UI builder is pretty useless too. But as I said, maybe I’m just retarded.
