For some time I have been seeking to gain more control over the
StringGadget as an input area. This topic is about that and a demo
linked later that I hope you will test and give me some feedback on.

Ultimately, I would like to see the StringGadget extended with two
more optional paramters, filter and mask.

Definitions:
"Filters" - allow the entry of only the characters that are present in the
defined filter. Filters can be very restrictive, but flexible, in application.

"Masks" - create the format of the entry and also determine the accepable
length of the input. Common masks include telephone number, social
security number, zipcode, etc.. Masks consist of a position defining character
and permanent placeholders.

A more detailed explanation is in the demo's help area.

and others if you search on "filter" or "mask" may apply.

The demo may be downloaded from:

Feel free to download it and try it out. I would appreciate your feedback
and suggestions. I am certain it is not perfect and some extensions
are forthcoming.

I plan on making the source code available after further testing and
cleanup.

Thanks,

Hi TerryHough,

I'm interested in testing the functions.!!!!

Let me know.

Thanx Frans (xstreur)

Very nice job!
I tried to really give it a good testing for you and the only bug I could find was this:

-Go to the currency tab and type in a number like 123.45
-Go back and delete the decimal...

You can then enter invalid data... The same problem exists with all the masks....
Other than that, it seems pretty unbreakable

Thank you, and thanks for testing this.

Yes, there is a problem when a "placeholder" character that was inserted
by the mask is deleted. I haven't found a workable and acceptable
solution for that occurence yet.

It is pretty easy to insert the "placeholder" during the initial entry of data,
but reliable realignment with the mask after a "placeholder" is deleted is
proving a bit more difficult.

One current solution is to clear the entire field if a "placeholder" character
is deleted. That seems to be too drastic and isn't very user friendly.

The current code also allows pasting of data that contains an invalid
character. That is because I chose to make the filter routine speedier by
checking each character as it is entered, rather than checking every
character in the input area every time a character is received.

Thanks again for testing and I appreciate any suggestions you may have
to make this more functional.
