SkinForm Component for Delphi 3 and 4
Copyright 1999 FriendSoft All Rights Reserved.
http://friendsoft.yeah.net
This component can be freely used and distributed in commercial and private
products, if you like it, please drop me an e-mail and send your screenshots.
Please feel free to contact me if you have any comments or suggestions.
Author: Xue Huai Qing [[email protected]]
Some functions come from Jscalco & Eddie Shipman, many thanks to them.
Thanks to Andre Inghillieri for his suggestions and improvements.
Thanks to Konrad Swart for his .dcr file.
Thanks to all people who give me a lot of encouragement and suggestions.
Description:
============
Are you bored by Windows95 UI? Do you want to create an application which
has a cool and changeable UI just like WPlay and WinAmp?
If so, SkinForm might be the thing that you want. This component can help
you to change the visual appearance of your project and make non-rectangular
windows forms quite easily.
Usage:
======
1.Make the skins of your applications, they are must be in bitmap format.
2.Make a skin file just like the skin file in the demo.The file format is
described in the readme file.
3.Use LoadSkinFile to load a skin file.
4.Add your own code to catch the following events:
OnMouseDownNotify, OnMouseMoveNotify, OnMouseUpNotify
History:
========
1.00 Initial release
1.01 Clean the code and make it compatible with Delphi 3
1.10 Add functions to manage the information of dispaly area
Reduce the action of refresh
Add an OnSkinChanged event
Many thanks to Andre Inghillieri for his suggestions and improvements
1.20 Add support of trackbar
Fixed bugs of displaying text
Reduce the blinking time
