Hi...
Can anyone tell me where I can get the Amount of chars, which are written in
an intuition string gadget ? I want to say WHILE the user writes... Not if
he clicked anotherwhere or pressed return... So that I can code a counter,
which increases while I'm writing, and decreases when I'm using backspace...
Hope that was understandable...
Thx...
C'ya

Use a string-gadget hook. There's an example of how to use such hooks
in the RKRM: Libraries and on the RKRM Companion Disks (Aminet:
dev/misc/RKRM_Libs[123].lha).

Nowhere. You could read out the gadget every INTUITICK and compute the
nuber of characters from the text buffer.

But a better method would be to create a BOOPSI subclass of string
gagdets with its own input method that passes the count to the
application (or another BOOPSI gadget that displays the number).

Can't you just read the StringInfo? To actually get the number for every
character as it was entered you would need the boopsi gadget.
