TSelectionFound = Procedure(Sender:Tobject;const TypedText,Foundtext:String;
ItemIndex:Longint) of object
TEditCheckList V 1.0
(c) Olivier Dahan March, 23th 1996
This component is a TCustomEdit child. It not allows text input but
posess an Items (TString) property where to stock all "legal" values, like
a Combobox.
The main difference with a Combo is the way the values are used.
In the TEditCheckList the user can use Up and Down Arrows to directly
get access to all values and he/she can type characters used as an incremental
search seed. By example, if the Items property contains "July/Juliet" and
if "J" is typed, the control displays "July" (the first corresponding). If
the user enters "U" and "L", the control stays on "July", and if he/she next
types "I", the controls displays "Juliet".
The typed characters remain in the control memory until arrows are used or
"escape" key is entered.
The control shows, as a selection, the number of typed characters. In our
example (July/Juliet), at the end of the sequence, Juliet is displays and
"juli" are shown as a selection. This is a good visual way to show the
silent incremental search text.
When an entry is found in the list of values, the OnFound events is
fired. So, you can connect here some code to hold this special condition.
The OnFound event return the sender, the found item (text and index in
the Items property) and the incremental search text.
Used keys are:
* Up and Down arrows to navigate throught the list of values
* 'A'..'Z','0'..'9' add a character to incremental search text
(case insensitive)
* Escape blanks the incremental search text
No display change (but no visible selection).
* Back Erases last character of incremental search text
TEditCheckList is not intented to be used as a text input control. Its
creator switches the ReadOnly propery to true. Its a Tedit sibling but
it acts more like a ComboBox.
