Toggle a checkbox on a card with long press does not work

[keram]

Hello,

I have a checkbox on a card. The script on the card has this code to imitate Android long press:

Code: Select all

on mouseDown
   wait 700 millisecs with messages
   if the mouse is down then
      ## treat like long mouseClick
      -- do something
   end if
end mouseDown

When I click to select the checkbox it does show its selection icon but it reverts back to unselected right away. I have to hold the mouse down little bit longer to get it selected so it stays on.

Of course it has to do with the mouseDown handler in the card. I just cannot figure out how to bypass that handler for the checkbox.

How to do it?

Set a script local variable on mouseDown that holds the current milliseconds. On mouseUp, compare the current milliseconds to the number in the variable. If it is > 700 then it is a long press. The mouseUp handler should do all the actual work, the mouseDown handler only records the time of the press.

Thanks Jacqueline,

I changed it to:

Code: Select all

local sPressStart

on mouseDown
 put the milliseconds into sPressStart
end mouseDown

on mouseUp
   put the milliseconds into tPressStop
   if tPressStop - sPressStart > 700  then
      show grp "a"
      hide grp "b" 
      put "this was a LONG press" into fld "message"
      wait 1 sec
   else 
       put "this was a SHORT press" into fld "message"
   end if
   show grp "b"
   put tPressStop - sPressStart && "milliseconds"  into fld "duration"
end mouseUp

Now the selection of the checkbox works properly. But it's a little bit different kind of long press since the "doing something" happens first on mouseUp, e.g. the buttons 1-3 show first when the press is released, while in the original post they show up after 700 millisec while the press is still down which is more Android-like.

But I guess there is no other way? The calculation has to be done.

You could try moving the long press code into a mouseStillDown. That should work if you make sure to exit the handler if the time is shorter than 700 ms. Continue to use mouseUp for a plain tap.

Yes, that works very well. Thanks!
