Cool library!
One note: demo fails to run on iPhone.

Unfortunately, I have no iPhone, and may have to leave that debugging to others.

I thought I would also try out this code, but it quits with errors. SImilar to what happens in the next post from this contributor, I get syntax errors, first with the line click=0 in DEF tp , and then if I comment that out, the error just moves to another line. Any suggestions?

Sneepy,

I keep going from one error to the next, and even when commenting out the syntax error, eventually there will be code that has to execute it, meaining I can't leave it commented out.

Also, from what I see, I doubt you even got this to work on an iPad, let alone an iPhone.

If you are looking for others to debug your code, this is not the way to get us to help you, as code that is posted here in BASIC Programs must work. Mr. K should have known that. I know he said this is cool, but how can that be determined if it does not work.

I suspect that you have code that does execute it properly, but you may not have given it to us for some reason.

I've flagged your post as you need to provide a working copy. If you can't get it to work, at least have the courtesy of telling us what issues you are having. Then there are plenty of us who will help you out, including me.

But I am not into debugging an entire program with no idea why you can't get it to work or give us the code that executes these routines properly.

George.

INBOXOK() returns 1 if inbox ended with the ok button, 0 for cancel
HIDEINTERFACE() hides all the visible buttons, switches, lists, fields, and sliders so
they don't cover up the boxes
RESTOREINTERFACE() shows them again

BOX(text$, parameters$) takes text and fits it into a box

/*
higher order functions than touch(x,y) for touch interface

TAPX() and TAPY() return the coordinates of the click, double click, or start of drag
TOUCHSTART() = 1 while a touch is going on and click has not been decided - first 100ms
CLICK() = 1 if the most recent touch activity was a click, else 0
DOUBLECLICK() = 1 if the most recent touch was a double click, else 0
DRAGGING() = 1 if the ongoing touching of the screen is dragging
DRAGGED() = 1 if the most recent completed touch was dragging
DRAGENDX() and DRAGENDY() are the end of the last drag
DRAGSTARTT() and DRAGT() are the start and ongoing/end times of the drag
TAPPOLL() is the polling routine to detect the touches and follow the time. 
taps.clicktime is the duration in ms of touch after which it is a drag and not a click 
x and y are determined by the first touch. click, double click, and dragged persist until polled or the next touch starts a new event.

I think sneepy is long gone. I haven't seen a new post from him in ages. In his remarks at the start of the code, he says that the taps library is "embedded" at the end of the code. Did you find that and save it as a separate file? I did a quick search and did not see anything embedded, so I'm not sure what he meant.

He shouldn't be. He just posted this last week.

Yes, I copy the entire post, code and all, and I comment out the posted comments which I keep with the code, just in case I missed something. I even uncommented the section he noted to test it.

Also "def tappoll" is commented and is pseudo-code.

Whatever other library he hasn't supplied, and I did a search before I flagged the message. I believe this post is closed as I got notification that it was. If this posted, then maybe it will be closed soon.

Too bad, this could have been useful..

Are you guys tripping or what?.
Surely you realise even if sneepy's code worked in 2014 it's most likely not going to work after several Smart Basic upgrades. You guys seem to have forgotten that Mr K manages to change smart Basics language behaviour with almost every upgrade.

There has been sixteen smart BASIC upgrades since this topic was created.

Don't exaggerate please. I remember only one occasion: a mod of the INT () function. You know of other mods that caused programs to behave different?
