ABILITIES
=========

TRadioScrollGroup allows various radiobuttons to be set in a scrollable area.
The radiobuttons CANNOT be set at design-time, only at run-time !


PROPERTIES, EVENTS & METHODS 
============================

ITEMS
The run-time 'Items' property is a Stringlist. Every line in the text becomes a
radiobutton. The Items property CANNOT be set at design time, and will therefore not
appear in the object inspector. You have to specify options at run-time (in your program
code, or loaded from a database, textfile,...)

	ex.	RadioScrollGroup1.Items.Add('This is an option');


ITEMINDEX
This run-time property determines which radiobutton is selected. The numbering starts
from 0. An ItemIndex of -1 means that no radiobuttons are selected. You can read and
write ItemIndex. When selecting a radiobutton within your program, the appropriate
radiobutton scrolls automatically into sight.

DISPLAYCONTENTS
To display the radiobuttons (as determined in 'Items') on screen. 
This does NOT happen automatically. You have to call 'DisplayContents'.

CLEARCONTENTS
This procedure clears the radiobuttons from screen.

LEFTMARGIN, TOPMARGIN, LINEHEIGHT
These are both design time and run time properties. At run-time, call 'Displaycontents'
again after changing these properties.

ONRADIOCLICK
This event is generated when a radiobutton is selected (by the user or by the program).
Parameters are the number of the radiobutton and the associated string.
