Title: Does a touchscreen monitor only report CLICK events only?
Post by: unclet on January 29, 2008, 01:14:00 pm

In my jukebox software if the user wants to increase the volume then the user can click the increase volume button using the mouse.  If the user clicks one time (ie: presses down the left mouse button and then releases the left mouse button quickly) then the volume is increased by one interval only.  If the user presses the left mouse button down and keeps it down, then the volume is increased continuously until the user releases the left mouse button.

Now, if I install a touchscreen monitor (ie: no more mouse interface), then can the user have the volume continuously increase by pressing their finger on the volume button, or will the touchscreen simply report this as one click only, thus resulting in a one interval volume increase only?

Hope this question made sense....

Depends entirely on the software you write for it. But usually they behave like a key press. So the longer you are touching it the longer it shows as held down.

You can touch and drag on most touch screens. So you could even have a slider for volume control.

Works fine on a elo software when option is set to mouse emulation,  if set to cick on touch it has to be repeatedly pressed to go up or down.
