 HP Prime MOUSE commandMessage #1 Posted by Sans on 14 Oct 2013, 6:35 a.m. Hi, I'm learning the using of MOUSE() command but I can´t get to understand how it really works. I wrote a little program that change the color of the screen depending the position of the pointer, but I have the following questions: 1.- How can I stop the loop until the next touch of the screen? I tried with BREAK and WAIT with no succes. 2.- What is the difference between the 0 and 1 value of MOUSE(4). 3.- Is there another alternative to wait for the touch of the screen whitout using a loop? My goal is just to create a button to execute one action. Sorry if my questions are too trivial. EXPORT TOUCH() BEGIN LOCAL xi,ni; WHILE ni:=1 DO ni:=B->R(MOUSE(4)); RECT(); xi:=B->R(MOUSE(0)); IF xi<160 THEN RECT_P(0,0,160,240,#000000,#0000BB) ELSE RECT_P(160,0,320,240,#000000,#FF0000) END; END; END; END;

Most likely will be something like WAIT(-1) to also stop on mouse presses. 2. 1 should indicate (I believe) that you have a completed touch event (eg - finger down then up) with no additional drags, movements, etc. 3. Not at the moment. TW Edited: 14 Oct 2013, 10:33 a.m.

If so, how is it flushed? Does calling MOUSE() immediately pop a mouse event?
