+Name: NiceGrid
+Author: "Jean Pierre Anghel" <jean-pierre.anghel@orange.fr>
+Date: 2012-01-21
+Description:
+This grid widget is a port of the VCL NiceGrid component found at
+[http://www.priyatna.org]. The original author gave permission to port this
+component to Free Pascal and fpGUI. Below is the emails giving permission.
+
+
+
+********************************************************************************
+Dear Jean-Pierre,
+
+Sure, I will be glad if NiceGrid can be ported to FreePascal.
+
+There's however an important bug that needs to be solved. It's when
+handling scrollbar messages. Current version can only handle 2 bytes
+(word) scrollbar offset, due to Windows limitation in the past. This
+will limit NiceGrid to only able to handle only a few thousands rows.
+Current Windows OS-es use 4 bytes (integer) scrollbar offsets. It should
+be easy to fix, I can help.
+
+Also I prefer to have one source code for NiceGrid using IFDEFs, instead
+a version for Delphi and another for FreePascal. I don't have much
+experience in LCL or fpGUI. Is it possible?
+
+Regards,
+Priyatna
