Re: How to give swiping precedence over scrolling on mobile?

2018-12-20 Thread Terry Judd via use-livecode

So, it seems like this approach works ok. Turned out there was an addition 
complication in that the items in my scrolling list are also selectable and I 
needed to prevent them being toggled on or off during a left/right swipe 
action. Anyway, this is what I ended up doing...

In the card script...

local pLoc, pTime, pV, pScroll

on touchStart pTouchID
   put the mouseLoc into pLoc
   put the millisecs into pTime
   put the scroll of grp "checkList" into pScroll
   put the mouseV into pV
end touchStart

on touchMove pTouchID, pTouchX, pTouchY
   put pV-pTouchY into tY
   put pScroll+tY into tScroll
   set the scroll of grp "checkList" to tScroll
end touchMove

on touchEnd pTouchID
   put the mouseLoc into pLoc1
   put (item 1 of pLoc)-(item 1 of pLoc1) into tX
   put (item 2 of pLoc)-(item 2 of pLoc1) into tY
   put the millisecs - pTime into tElapsed
   if abs(tX)>100 then # horizontal swipe
  if abs(tY)< 50 then # small vertical movement
 if tElapsed < 500 then # not too slow
if tX > 0 then
   send "mouseUp" to grp "nextBtn"
else
   send "mouseUp" to grp "backBtn"
end if
 end if
  end if
   end if
end touchEnd

And in the "checklist" script...

local pX

on mouseDown
   put the mouseH into pX
end mouseDown

on mouseUp
   if abs((the mouseH)-pX) > 50 then exit mouseUp
   # list selection code
end mouseUp

Using the Compass / GPS features of LC

Is anyone familiar with using LC to "guide" the user to a specific location.
For instance, if I have a marked and saved lat/long location, I want to have
the app show directions of how to return to the location after walking away
from it.  Not using google maps but instead using something like a "compass"
app to direct the user to the location while always pointing to the
destination.  Thanks.

Try version 7.1.4 and 8.1.10 to see

Hope it works!

Versions 7.1.1 and 8.1.3 no long working properly

2018-12-20 Thread James Hurley via use-livecode

I am having trouble running a stack on 7.1.1, Community

I have had no problem with it in the past. 

But now it will not display the Tools Palette. 

Closing any window I get the message “Do you want to save….” I have to click 
“Cancel” to proceed

The stack runs, but erratically. 

So I thought I would try 8.1.3 and have similar problems. Still the message “Do 
yo want to save…” when I close any window.

Is it me?

Thanks Bob,


Actually coming to think of it it would be easiest for you to just try 
"bnGuides".


When dealing with groups try with "Select Grouped" turned on and off. When 
turned on select the members of the group and click one control as the leading 
control.

When "Select Grouped" is turned off just select the group and drag it around 
and see how it deals with the members of the other group.


Note, the datagrid is just one group, the elements of the datagrid are not 
scanned.


for your convenience

Cool. Now I haven't tried it yet, but what would REALLY be cool is if it 
aligned a group based upon the contents of another group. That may be asking 
too much though. 

The way Illustrator goes about it is it tracks all points, then indicates 
whenever points align. Not sure how you did it though.

Interesting approach. Of course, the downside is that if anything changes, the 
method becomes ineffective for that new device or for all andriods if the 
change is fundamental enough.
