System.Windows.Forms (or SWF) is an API that the .NET framework providers for writing graphical applications. There are others, like <a href=http://www.cocoasharp.org/>Cocoa#</a>, <a href=http://qtcsharp.sourceforge.net/>Qt#</a>, and <a href=http://gtk-sharp.sourceforge.net/>Gtk#</a>, but on Windows, SWF is what developers use. <p> If your goal is to write cross-platform .NET apps (as mine is), then getting SWF working on the Mac is important.<p> It's pretty easy to do, too. I ran into a glitch with it giving an exception when I tried to run my test application, which turned out to be that I didn't have an X server installed. OS X comes with one, but you have to install it (it's not installed by default). Download it <a href=http://www.apple.com/macosx/features/x11/download/>here</a>. <p> I understand there is a "Cocoa Driver" for SWF that would let my .NET app run without X in development, but it's not ready for prime time yet. Still, this works for now.Thu, 01 Sep 2005 19:17:08 GMT
