what UI to use for touch screen application

Hi guys,

I have to develop an application which is touch screen application.
In that user is able to touch the screen and particular button is get pressed from touching the screen.

what should I use to show the UI ?

thanks in advance

I'm guessing your touch screen device has an API you can use?

Depends on the system.
Can you use Java SE? Then go for Swing. If I recall correctly, touches are handled as mouse events.
Can you use Java ME? Then go for that.
Any other systems?

there also a task in that i have to press particular button for particular amount of time.
means that button is get pressed for near about 5 secs...

is it possible using any api or i have to use thread operation.

its just like toggle button operation but for particular amount of time after that button should get released....

As we've asked you before, please tell us which device you're programming on. I can tell you to look at MouseListener, JButton etc but that won't make any sense if you're stuck to JME.

Touch Screen applications are no different from other ordinary applications, except that instead of mouse person is using touch-screen mechanism. So, the application 'usually' does not have to do anything special. It is the device which should be capable of translating 'touch' on the screen into a mouse event for underlying UI.
