With compiling agains mono it should be possible to compile once and use on osx, linux and windows even using the standards form classes in .net. But i a application i want to use drag and drop of panels for that i have the following c# code. But is that also useable on osx and linux?



using System;
using System.Windows.Forms;

public class MovablePanel : Panel
{
const int WM_LBUTTONDOWN = 0x201;
const int WM_NCLBUTTONDOWN = 0xA1;
readonly IntPtr HTCAPTION = (IntPtr)2;

protected override void WndProc(ref Message m)
{
if (m.Msg == WM_LBUTTONDOWN)
{
m.Msg = WM_NCLBUTTONDOWN;
m.WParam = HTCAPTION;
}
base.WndProc(ref m);
}
}



Or should i investigate in silverlight/moonlight?
