HP PRIME : strange behavior when trying user key capability Message #1 Posted by Damien on 31 Oct 2013, 5:08 p.m. Hi everyone ! Today i wanted to try the Prime user keyboard capability, on my young lady received a few days ago: (And i love her ! But not the ugly small font!) KEY K_Vars BEGIN IF CHOOSE(N,"Radian","Degree") THEN // MANUAL edition July 2013 // ! p575 HAngle var values are inverted ! IF N == 1 THEN HAngle:=0; END; // 0 for RADIAN IF N == 2 THEN HAngle:=1; END; // 1 for DEGREE END; END; SO, I am in Home function, with degrees for angle unit. I press shift+help, 1U appears on top left corner, i press the Vars key then the choose box appears, i choose option 1 to select radian, and angle setting switch from degree to radian, it works ! BUT AT THE SAME TIME THE APPLICATION LIBRARY OPENS. WHY ? something wrong with my HPPL coding ? Thanks ! Edited: 31 Oct 2013, 5:45 p.m.

Re: HP PRIME : strange behavior when trying user key capability Message #4 Posted by Tim Wessman on 31 Oct 2013, 7:52 p.m., in response to message #1 by Damien Currently, returning a string will generate a text event. A number is interpreted as a keypress. Add a -1 at the end and it will not press the APPS key. Every function will always return the last object in the runstream by default as the system is designed such that all functions must return an item. BEGIN IF CHOOSE(N,"Radian","Degree") THEN // MANUAL edition July 2013 // ! p575 HAngle var values are inverted ! IF N == 1 THEN HAngle:=0; END; // 0 for RADIAN IF N == 2 THEN HAngle:=1; END; // 1 for DEGREE END; -1; //returns -1, without this whatever value HAngle is set to will be returned. END; TW Edited: 31 Oct 2013, 7:52 p.m.

Re: HP PRIME : strange behavior when trying user key capability Message #5 Posted by Patrice on 31 Oct 2013, 8:25 p.m., in response to message #4 by Tim Wessman I don't remember UG telling about -1 to avoid keystroke.

Re: HP PRIME : strange behavior when trying user key capability Message #6 Posted by Tim Wessman on 31 Oct 2013, 9:06 p.m., in response to message #5 by Patrice Don't know if it does. I am just assuming anything that doesn't line up in the key number range won't do anything. TW

Re: HP PRIME : strange behavior when trying user key capability Message #7 Posted by Damien on 1 Nov 2013, 3:11 a.m., in response to message #4 by Tim Wessman Hi everyone, adding RETURN -1; did not change anything... Changing user key to Apps key: KEY K_Apps()// instead of K_Vars() BEGIN IF HAngle == 0 // RAD THEN HAngle:=1 // DEG ELSE HAngle:=0 // RAD END; RETURN -1; END; Now, the screen switch to APPLICATION LIBRARY corresponding to the key pressed... A problem with keyboard buffer ? Thanks

Re: HP PRIME : strange behavior when trying user key capability Message #8 Posted by René Franquinet on 1 Nov 2013, 8:49 a.m., in response to message #7 by Damien I think I will buy the Prime at the moment all childhood diseases have gone, but I am afraid some will remain. ;o)

Re: HP PRIME : strange behavior when trying user key capability Message #9 Posted by Tim Wessman on 1 Nov 2013, 10:38 a.m., in response to message #7 by Damien My mistake! Returning anything outside the key range or a string will just pass through as if you did nothing and process like normal. That range is 0-203 (4 key planes, 51 keys). I'd recommend returning something like 46+51*2 or 148 which will, correspond to the alpha plane of the ON button (which will be a NOP basically). Right now, user keys were really just implemented to support rearranging the keyboard, or returning some text. TW

Quote: Right now, user keys were really just implemented to support rearranging the keyboard, or returning some text. To my mind, it greatly limits the use of user keys. Thank you for your help.

Re: HP PRIME : strange behavior when trying user key capability Message #12 Posted by Damien on 2 Nov 2013, 3:36 p.m., in response to message #11 by fabrice48 Hi, In the user manual, (a pdf file edition July 2013) on page 575 if i remember well. Dam.

It's also explained in its help screen. Press Home Vars 6 Help. It's helpful to look at the help screen for all the "Settings" vars. Except for Bits and Signed, they seem to be correct. ;-)
