Welcome to the..

TEyes Component for Delphi!

TEyes is a native Delphi VCL component that emulates (somewhat) X-Eyes. Finally, this great feature of some Operating Systems is now available for the world's greatest development environment: Delphi!

When I saw one of those Eyes apps some time ago, I thought: `this has to be available to Delphi Developers too!'. I dug into some math (component building was the easy part, believe me) and this is the result. I must add: Special thanks go to Ferns Paanakker for Helping me with some of the Math involved. When the first version was working correctly I decided to tidy the code up a bit to `Borland' standards (meaning clean code with just enough comments to go by <g>), add a fews docs and a demo app. and release the stuff 'on the net' (where you found it, presumably).

This stuff is freeware, but the usual applies: Use at your own risk. I take no responsability to anything involved in using this Component and All Rights Reserved by the Author. Usage of this component means that you agree with these terms.

Files included in the DELEYES.ZIP package:

• EYES.PAS: Source to the TEyes component;
• EYES.DCR: Palette bitmap;
• EYES.DCU: Compiled unit of the Component;
• EYES.HTM: This file;
• EYES.GIF: Used in Eyes.htm;
• GOLDEYE\GOLDEYE.DPR: Demo project `Golden TEye';
• GOLDEYE\GOLDMAIN.PAS: Demo project, Main unit;
• GOLDEYE\GOLDMAIN.DFM: Demo project, Main form;
• GOLDEYE\GOLDABT.PAS: Demo project, About unit and
• GOLDEYE\GOLDABT.DFM: Demo project, Aboutform.

Also added is the 16-bits version of the same component:

• EYES16.PAS: Source code for TEyes 16-bits;
• EYES16.DCR: Palette bitmap and
• EYES16.DCU: Compiled unit.

The Demo App should work both with Delphi 1 and 2, if using Delphi 1 you will need to change the reference to EYES16 in the uses clauses.

Installation instructions:

1. Place EYES.PAS and EYES.DCR in a directory located in the Delphi Search path. That could be as complicated as 'C:\PROGRAM FILES\BORLAND\DELPHI 2.0\LIB' or simply 'C:\EYES';
2. In the Delphi 2.0 IDE, select Components|Install;
3. Select 'Add' component;
4. Browse to EYES.PAS and Click Ok;
5. TEyes should now be available on your component palette under the "Samples" page and..
6. Enjoy!!

Installing the component in Delphi 16-bits is likewise.

Using the GoldenTEye demo is quite easy and does not need any instructions (I hope).

Some Comments:

The TEyes Component source code is also released, as should be the case with any 'freeware' stuff: one should be able to learn from it. With that in mind I did my best to make the whole quite 'clean'. TEyes itself descends from TCustomEyes (you could for instance make a TOldBlueEyes component that descends from TCustomEyes and has clNavy Pupils!). Also a TEyesEditor is supplied with gives some 'About' information to anyone double-clicking on it at Design-Time.

The code is pretty self-explanatory. Some comments have been added in the code that calculates the pupil position (that's the hard for us Delphi developers but probably basics for a math teacher), the rest should be quite easy to read (and understand) for anyone involved in Component building.

Have fun!

• Dr. Bob - The best place for Up-to-Date Delphi info;
• Athena Software - My own homepage (if you want some more information about Athena Software in general or want to see if some interesting other components have been added, no promises, not much time is involved in the construction of this page at the moment).
• SDGN - Finally, Software Developers Group Netherlands is on the net. Please note that I head the Delphi division at the moment. If you're in the Netherlands and serious about Delphi development, you just have to check this page.
