A HotSpot is a transparent box which you can drop on an image or any
other visual component. This box can receive mouse events so that you 
can tell when the cursor is over the hotspot. You can put a box of any
colour around it and have it flash if desired. Unlike a TShape, this box
is drawn as four thin rectangles; this avoids invalidating the inside
of the hotspot, and stops annoying bits of background flickering at you.

This version allows the parent to be reassigned at runtime.

THotSpot is freeware - use it how you like. 	

<< Using THotSpot >>

Just drop it on a component, pull it about and set a few properties.
Assign procedures to the mouse events and off you go!

If True, a box is drawn around the hotspot. If FlashTime > 100, this box

<< Installation >>

Backup your 'complib.dcl' file as a precaution.
Select 'Options', 'Install Components'.
Select 'Add', 'Browse'.
Select the directory containing the HotSpot files.
Select 'hotspot.pas' and click OK on each box that appears.
The Hotspot control will be added to the 'Samples' section of your
component toolbar.
If anything goes wrong, restore your backed-up complib.dcl and try
again after correcting any obvious problems.
