Signature Capture on PDA

Can anyone help with signature capture on a PDA.
Somehow I need to capture a signature written on the screen and hold it in a
JDataStore DB.

I figure that varbinary will hold the signature ok, but I can't figure out
how to capture the signature.

What AWT component should I use and how?

Or can anyone point to any article or tutorial on the subject.

Thanks,
Peter Strempel

Hi Peter,

I assume you know that we have awt based JBCL components in JDataStore 6 and
JBuilder 9.

I'm not sure what it means to "capture" a signature.

I have copied Sergio on this to see if he can help.

In PDA's there is usually a widget of some type that will capture a
simple 1 or 2 pixel-wide drawing and convert it to a datatype that can
be stored in a database. In NSBasic/Palm, for example, there is a
'gadget-based' widget that will do this and convert it to a string
type.

Peter is asking what's the best approach using JDS and whatever the
GUI toolkit is that he's using.

Peter,

You'd need to trap the data that get's stored in whatever AWT or JBCL
object that you decided to use into a data stream that you can
serialize and unserialize. Then you can write to whatever
BLOB-oriented field in JDataStore you wish.

What I mean by capturing a signature is:

A customer signs their signature on the PDA as an acknowledgement of work
done. I then want to store the signature(using JDS) for future reference
and printing.

I known I can use a blob type in JDS ok, but my major
problem is knowing what AWT object or component I can use to trap
the signature.

My problem is knowing which AWT or JBCL object I can use to trap the
signature,
and how to present it on the UI for the user.

For example, textarea and textfield don't seem useable in the context of
trapping a
signature, rather, only useful for entering data via a keyboard.

So is there any way I can use these components, or what other options exist?

Peter,
I've almost finished creating my Signature Capture Java Bean the runs on
PersonalJava. It saves the signature locally as a bitmap on your Pocket PC.
I already have a Compact Framework signature capture control for sale on
Handango.com.

The Java Bean you are creating sounds perfect for my application which runs
on a PersonalJava platform.

I would be interested to hear more when it is completed.
