HP Prime DRAWMENU

Hello,

Somebody knows how to detect a click on a menu drawn with DRAWMENU command on HP Prime ?

Here's what I used:

  m := MOUSE;
m1 := m(1);
mx := m1(1);
my := m1(2);
menu := softmenu(mx,my,n);

where softmenu() is defined to be


////////////////////////////////////////////////////////////
// converts pixel x,y into a menu choice
// returns menu number (1 through n)
// returns 0 if an invalid menu option was selected (>n) or tap was exactly between two menu options
// returns -1 if y was not in softmenu region of the screen
softmenu(x,y,n)
BEGIN
LOCAL m;

m:=-1;
IF y >= 220 THEN
CASE
IF 0 <= x <= 51 THEN m := 1; END;
IF 53 <= x <= 104 THEN m := 2; END;
IF 106 <= x <= 157 THEN m := 3; END;
IF 159 <= x <= 210 THEN m := 4; END;
IF 212 <= x <= 263 THEN m := 5; END;
IF 265 <= x <= 319 THEN m := 6; END;
DEFAULT m:=0; // if it's right in between menu options
END;
// check to see if valid menu option was selected
IF m > n THEN
m := 0;
END;
END;
RETURN m;
END;

Thank you, I used this way with coordonates detection. I thought there was a specific command for the drawn menus.

#9

The list returned from a MOUSE call contains the x and y values
in the following format #nnn:16d
For example if I touch the menu key 6, I get #273:16d as the x pixel
coordinate. How can I extract the value 273 - the x value from this
expression? I can't use the list format of the x,y coordinates
in a conditional statement.

The B->R function converts these 16-bit integers to reals, but you don't have to; you can use comparisons without converting them. You can also use the SUB command (or subscript notation) to extract individual items from that list, of course. Hope that helps!
