Re: Programming for Touch Screens

It may help if you think of the touchscreen's surface as the square touchpad
surface on most laptops. The touchpad uses touch and interprets touching,
sliding your finger across it and tapping it as mouse functions. No special
program calls or functions are needed to use an application on a laptop
using a touchpad as opposed to using it on a desktop or with a real mouse.
The laptop's drivers take care of that.....just as the touchscreen monitor's
drivers will do for it.

Good luck with your project!

If I may interject.....

I believe what is being said here is that you should program the
application juts as you normally would using the mouse pointer to click,
double-click, select, etc. objects on the screen.

Then, when you have purchased a touchscreen LCD, the touchscreen monitor
will come with drivers that enable you to tap on the screen as well as
use the mouse to perform your application's functions. Those drivers
take screen input (touching the screen, tapping the screen, hitting it
with a big rock) and feed them to your application as though they were
coming from a mouse.

There is not special programming needed to enable the touchscreen device
in most instances. Proceed with your application (using a mouse as the
input device) and the drivers that come with the touchscreen device will
interpret screen signals as mouse inputs - making your application works
the same as it would with a mouse, without any program changes on your
part.

If I missed something, somebody please speak up.

Hi again Diego

I feel like I'm asking really silly questions, but I have to ask them in
order to understant

My client hasn't purchased touch screens yet, they want me to write the
software and in the meantime work out the hardware they want.

That being the case, can I just download a driver for a ANY touchscreen
and play around with that or each driver is specific to the brand of
touchscreen. Do you know?

If so, where would you suggest I go to get a driver for this?

Thanks again
Michelle
