Re: Mobile Scroller

[Tom Glod via use-livecode]

Just confirming that this has been solved, putting the
mobilescroller commands in the resizestack handler is the solution.
What I did was I put "resizestack" to be called from "orientationchanged",
which for some reason it seemed like a good idea at the time :/

Thanks Ralph.

RE: Mobile Scroller

[Ralph DiMola via use-livecode]

Tom,

Orientationchanged happens before the screen is actually rotated. This is why 
your scroll regions are not correct. Put your code in the resizestack handler. 
I delete and recreate the scroller, I don't remember if that is needed or I 
just started doing it that way. Scrollers work for me on both iOS and Android. 
If you are able to come up with your magic numbers that will make it scroll to 
the same place you must do a send in time for the  2 "mobileControlSet"s for 
both vScroll and hScroll. I use 100ms

That being said although all my apps support both portrait and landscape I use 
Orientationchanged very very rarely but when you need it it's invaluable.

Re: Mobile Scroller

[Brian Milby via use-livecode]

I have this working in SivaSiva for the stories module on Android.  It locks up 
on iOS so I have rotation disabled for now.  In my use case, the group is 
essentially the full screen with an image that is being moved around.  I’ll try 
to find the specific scripts tonight.

Thanks,
Brian

Re: Mobile Scroller Advice

[Brian Milby via use-livecode]

Thanks to a little off list help from Jacque, I was able to get this
working.  Here's the key piece:

   wait 10 milliseconds -- Panos workaround, bug #18924
   mobileControlSet pName, "hScroll", the hScroll of control pName
   mobileControlSet pName, "vScroll", the vScroll of control pName

The workaround in the bug report actually says wait 0 ms, but I found that
I had to increase it a bit for it to work on my test Pixel (I didn't try to
see how low I could go though).  I'm replying to myself to put the
information out there in case someone is searching the archives.

Thanks all,
Brian

Re: Mobile Scroller Advice

[Brian Milby via use-livecode]

It starts zoomed out with the whole image showing.  A tap will zoom in about 
25% each time until fully zoomed in (pixel match to display).  The idea is that 
the image will zoom from the center instead of from the top/left.  No 
transition effects are currently used.

At each size, the user can scroll around the entire image.  (It would actually 
be best to zoom around what is currently visible, but that is easy once I 
figure out the other piece.)

The issue is that if viewing a very wide panorama, then jumping to the left 
side isn’t very appealing.

Currently I do delete and recreate the scroller for each zoom, it just didn’t 
work right with the image centered in the group.

Thanks,
Brian

Re: Mobile Scroller Advice

[J. Landman Gay via use-livecode]

I'm a little confused. Do you want the zoom to happen within a group with a 
scroller?


I've done this a different way. Delete any existing scroller, lock the 
screen, resize the image and its group, unlock the screen with a visual 
effect like zoom in or whatever. Then recreate the scroller at the new 
group size.


Is that what you're asking?

Mobile Scroller Advice

[Brian Milby via use-livecode]

Greetings on this lovely Tuesday evening.  I'm in need of a little mobile
scroller wisdom.

I'm working on an app that runs on mobile devices (Apple and Android).  We
are presenting an image and have enabled the ability for the user to tap on
the image to zoom in.  Everything is working except the only way that I
have been able to get the scroller to work reliably is to place the image
at the top/left of the group.  What we would really like to do is keep the
image centered on the screen as it expands.

It may be totally obvious, but before I spend a bunch of time throwing
darts and hoping for a bullseye, I thought it would be good to at least ask
for a little help.

Thanks for any assistance you can provide,

RE: Mobile scroller misaligned

[Ralph DiMola via use-livecode]

J,

Sorry I meant send this to you last time you asked and got sidetracked, then 
spaced out and forgot. After creating the scroller do a send in time to a 
handler to set the non-zero scroll. I use .5 seconds but less might work.

I am still struggling with native scroller alignment when the scroll must be 
set to something other than zero. Since I've asked here twice with little 
response, maybe I just need to know more about how scrollers work under the 
hood. Panos? Anyone?

* If I set the vScroll or hScroll of a scroller, are any messages sent? 
Does this affect the underlying LC group in any way?

* Right now, I'm setting the scroll of a LC group and then setting up a native 
scroller to use the same scroll. This fails. Should I be reversing the process, 
and set the scroller's scroll first followed by the LC group scroll? That's 
kind of how it works when scrollerDidScroll is called. I wasn't able to get 
this to work but maybe I missed something.

For testing, I copied a card from the real project with the same scroller 
scripts. I could not set the scroll in the handler that created the scroller, 
but I could set it later after the creation handler finished. But in the real 
project, identical scripts fail. I can't trace why.

I've been tring to fix this for a couple of months now, so any info would be 
appreciated.

Re: Move several fields by a mobile scroller to allow to enter text into the lower fields

[J. Landman Gay via use-livecode]

I usually move the group up to the top of the card on keyboardActivated and 
back down on keyboardDeactivated, but if you have a lot of fields or groups 
that can be a pain. There's a bug report /feature request to add card 
scrolling which would be the ideal way to fix the problem but it hasn't 
happened yet.


It used to be that acceleratedRendering would auto-scroll the field into 
view but that was an unintentional bug that was fixed. Sometimes it was 
handy though.

I tried that but it didn't scroll to the far edge, so I set it back to

I'll try to set up a sample stack later and put it in the bug database.

Re: Setting mobile scroller hScroll fails

[J. Landman Gay via use-livecode]

Whenever someone says "math" my eyes kind of glaze over and my brain 
shuts off. I'm using your sample script to resize the group so it 
expands to the screen edges, which works great. I'm not sure how to 
change the scroller so it works with that setup, but I did wonder if 
scrollers were limited to the card size and that might be why it wasn't 
working.


I think I'll write it up as Monte suggested, though I'm not sure whether 
to call it a bug, a feature request, or just impossible.

Thanks Monte, I did over-summarize. I'm not sure why it's going wrong,
but it sounds like it's something I'm doing. I have a standard
"createScroller" handler that I've been using for years, but I've never
had to set the hScroll before. It's always been zero.

In this case, I set the hScroll of the group to the formattedWidth of
the group, which may be wrong. The engine seems to compensate though and
sets the scroll as far as it should go. Then I call "createScroller" and
pass the name of the group. The handler:

command createScroller pName
-- pName = the long ID of a grp
put the rect of control pName into tRect
put the hScrollBar of control pName into tHScroller
put the vScrollBar of control pName into tVScroller
put the hScroll of control pName into tHScroll
put the vScroll of control pName into tVScroll
set the hScrollBar of control pName to false -- remove fld scrollbars
on mobile
set the vScrollBar of control pName to false
mobileControlCreate "scroller", pName
mobileControlSet pName, "rect", tRect
put ("0,0," & (the formattedwidth of control pName) & "," & the
formattedheight of control pName) into tContentRect
mobileControlSet pName, "contentRect", tContentRect
mobileControlSet pName, "hScroll", 0
mobileControlSet pName, "vScroll", 0
mobileControlSet pName, "hIndicator", tHScroller
mobileControlSet pName, "vIndicator", tVScroller
mobileControlSet pName, "hScroll", tHScroll
mobileControlSet pName, "vScroll", tVScroll
mobileControlSet pName, "visible", true
end createScroller

I initialize both the group and the scroller to 0 before doing anything
else, because when I wrote it I couldn't get them to align correctly
otherwise. I should also probably mention that I'm using fullscreenMode
"showAll" and the group is expanded beyond the borders of the card to
fill the screen; i.e., it probably has a negative left margin and a
wider right margin. When the scroller finally does scroll (after
resetting itself) it scrolls too far at the left side by the number of
pixels between the screen left and the card left, and cuts off the same
amount on the right side.

Can you see what I should change?

I want to verify this is a bug and not just me.

I'm creating a mobile scroller over a group. I want the group to initially 
display with its hScroll all the way to the right. I'm doing this:

zoom the group out to fill the screen
create a mobile scroller with the same rect
set the hScroll of the group to its formattedWidth
set the hScroll of the scroller to the scroll of the group

If I insert an answer command to show the scroller's hScroll it reports the 
correct number. But the scroller always acts like its scroll is 0, and it won't 
scroll to the left at all. But scrolling it to the right zaps both it and the 
group to zero and after that it scrolls normally.

I've also tried not setting the group's scroll and just setting the scroller 
alone, thinking it might trigger the scrollerDidScroll handler, but it doesn't.

If I don't set any hScroll at all on either the group or the scroller, all is 
well.

Has anyone else seen this?

The max scroll will be the formattedWidth of the group - the width of the group 
unless you have unboundedHScroll true. I _think_ if it’s false then the engine 
will automagically clamp that though.

I’m really not sure at this stage. Have you tried logging the x,y values you 
get in scrollerDidScroll? This may need a simple stack to reproduce it and an 
email to support so we can figure out what’s up.

Re: Setting mobile scroller hScroll fails

[J. Landman Gay via use-livecode]

Thanks Monte, I did over-summarize. I'm not sure why it's going wrong, 
but it sounds like it's something I'm doing. I have a standard 
"createScroller" handler that I've been using for years, but I've never 
had to set the hScroll before. It's always been zero.


In this case, I set the hScroll of the group to the formattedWidth of 
the group, which may be wrong. The engine seems to compensate though and 
sets the scroll as far as it should go. Then I call "createScroller" and 
pass the name of the group. The handler:


command createScroller pName
  -- pName = the long ID of a grp
  put the rect of control pName into tRect
  put the hScrollBar of control pName into tHScroller
  put the vScrollBar of control pName into tVScroller
  put the hScroll of control pName into tHScroll
  put the vScroll of control pName into tVScroll
  set the hScrollBar of control pName to false -- remove fld scrollbars 
on mobile

  set the vScrollBar of control pName to false
  mobileControlCreate "scroller", pName
  mobileControlSet pName, "rect", tRect
  put  ("0,0," & (the formattedwidth of control pName) & "," & the 
formattedheight of control pName) into tContentRect

  mobileControlSet pName, "contentRect", tContentRect
  mobileControlSet pName, "hScroll", 0
  mobileControlSet pName, "vScroll", 0
  mobileControlSet pName, "hIndicator", tHScroller
  mobileControlSet pName, "vIndicator", tVScroller
  mobileControlSet pName, "hScroll", tHScroll
  mobileControlSet pName, "vScroll", tVScroll
  mobileControlSet pName, "visible", true
end createScroller

I initialize both the group and the scroller to 0 before doing anything 
else, because when I wrote it I couldn't get them to align correctly 
otherwise. I should also probably mention that I'm using fullscreenMode 
"showAll" and the group is expanded beyond the borders of the card to 
fill the screen; i.e., it probably has a negative left margin and a 
wider right margin. When the scroller finally does scroll (after 
resetting itself) it scrolls too far at the left side by the number of 
pixels between the screen left and the card left, and cuts off the same 
amount on the right side.


Can you see what I should change?

Something similair with 2 fields, of which one did scroll (vertical) and 
the other not, Although the script for both was the same except for some

I just tried both Scott's touchMove solution and Paul's
scrollerDidScroll suggestion but neither seem to work on Android.

I'm not surprised there was no scrollerDidScroll message, because
the field width fits the scroller contentRect, so there is nothing
to scroll. It may be working on iOS because there you have a
"bounce" option which allows overscrolling. Android doesn't have
that.

I had hopes for the touchMove solution because that message does
fire sporadically but it failed also. In my tests yesterday I saw
that the message fired fitfully, but even when it did the mouse
position was wrong. I attributed that to the fact that I was
logging the coords to a field, but maybe there's more to it because
after a few responses the logging stopped completely.

Just tried this simplified version and it works fine too:

on scrollerDidScroll hOffset, vOffset // Scroll Detect //
 
   if hOffset <0 then ##-->> Detects the Horiz swipe <<--##
  moveBack
   else if hOffset >0 then
  moveForward
   end if
   
   set the vScroll of group "scrollArea" to vOffset ##-->> Scroll the field

end scrollerDidScroll

No, the hScroll prop is still false, you are just detecting and using 
(diverting) the information that the scrollerDidScroll message would have used 
to set the hScroll, but it never gets set.

This is the handler:

on scrollerDidScroll hOffset, vOffset // Scroll or Swipe Detect //
 
   if the hScroll of group "scrollArea" <0 then ##-->> Detects the Horiz swipe 
<<--##
  moveBack
   else if the hScroll of group "scrollArea" >0 then
  moveForward
   end if
   
   set the vScroll of group "scrollArea" to vOffset ##-->>  Scroll the field 
vertically <<—##

end scrollerDidScroll


It is just a workaround, and it’s not perfect, but may keep you going until the 
main problem is fixed.

The actual hScroll of the field isn’t set, only the vScroll is set in
this example, but it can detect that you are attempting to scroll
horizontally and so you can use that info to initiate a swipe.

It is only a workaround implemented by intercepting the
scrollerDidScroll message, you don’t need to ‘set' the scroll sent by
the message, but you can detect it and use it to swipe.


Right, but does that mean the hscroll property of the mobile scroller 
must be true? Right now mine's false so I assumed it wouldn't even try 
to detect scrolling horizontally. I can change that setting of course.


But your solution and Scott's are very similar so it must work. I'll 
experiment with both. Thanks for the ideas, both of you, but I sure wish 
we could use a simple mouseUp to detect it. It would save a lot of trouble.

Re: Swipe gestures on a mobile scroller

[Scott Morrow]

I used touchMove and found it at least partially reliable for horizontal swipes 
on iOS (not tried on Android)
Something like:

global gHorizontalSwipeDistance
local lMouseStartH
local lMouseStartV


-- put 80 into gHorizontalSwipeDistance -- depending on the resolution during 
startup

on touchStart pID
   put the mouseV into lMouseStartV
   put the mouseH into lMouseStartH
end touchStart

on touchMove pTouchID, pTouchH, pTouchV
   -- see if there was a horizontal swipe
   if (abs(pTouchH - lMouseStartH) > gHorizontalSwipeDistance) AND\
   (abs(pTouchV - lMouseStartV) < gVerticalSwipeDistance) then
  -- they swiped

   end if
end touch

BTW, there appears to be a related bug that got fixed:

MouseUp wasn't being sent when a native scroller was active. It looks 
like they fixed that one but forgot to check related swipe mouseUps.

I haven't tried Paul's workaround. I'm not sure how it could work, since
the horizontal scroll of my field is always zero. It doesn't scroll
horizontally at all.

The fix should really be in the engine though.

Re: Swipe gestures on a mobile scroller

[J. Landman Gay]

Well, it's good to know I'm not alone I guess. ;) I just wish I'd asked 
earlier, before I spent some hours tracking down the problem. I'd like 
to think the omission of mouseUp/touchEnd messages was an oversight, 
since we do get all the other mouse messages.


I haven't tried Paul's workaround. I'm not sure how it could work, since 
the horizontal scroll of my field is always zero. It doesn't scroll 
horizontally at all.


The fix should really be in the engine though.

The scroller has its hScroll property set to false if that

Re: Swipe gestures on a mobile scroller

[Paul Hibbert]

Kind of! I built an iOS app that needed to display some long fields of text, I 
built some pages based around this lesson:

http://lessons.livecode.com/m/4069/l/94412-creating-a-native-scroller-to-scroll-a-field?id=94412-creating-a-native-scroller-to-scroll-a-field

I had the same problem with navigating cards using swipe gestures because the 
field covered the majority of the card, I managed to work around the problem by 
modifying the scrollerDidScroll handler to:

on scrollerDidScroll hOffset, vOffset
// When the user scrolls horizontally, navigate in the desired direction

if the hScroll of group "scrollArea" <0 then // Detect the horizontal swipe

   moveBack // Stack handler to move back to Index card

 else if the hScroll of group "scrollArea" >0 then

   moveForward // Stack handler to move to next card

end if

// When the user swipes vertically, scroll the displayed content

set the vScroll of group "scrollArea" to vOffset

end scrollerDidScroll

To make this work I had to set these properties on the text field;
traversalOn “false”
autoHilite “false”
lock text “true”
So this may not work if you need the user to be able to modify the text unless 
you can give them a method of changing between edit/navigate modes.

I’ve managed to update the lesson file, it's on dropbox, so if it helps here it 
is for you to test:
https://www.dropbox.com/s/ak234nlwbgfko3p/Scroll%20Test.livecode?dl=0 


It does seem to be reasonably reliable, but not if you tend to swipe too fast, 
I have’t tried it on Android though.

It isn't really, it just acts like that.


I see the scroller getting created and do its usual short flash of the
scroll indicators but you can't use it but instead it sends mouseup to the
field that goes to another card that has scrolling results and that scroller
works perfect on the new card. Scrollers on other cards also work perfect.
I've used the mobile scroller many many times with no problems.
I moved the scroller rect below the field for a test and it is on top of all
the other controls and scrolls the field above as expected.
This happens only on Android. iOS works as expected.


I had to deal with something similar on Android the other day. It wasn't 
quite the same setup as yours, but similar. I worked around it by 
handling touchStart and touchEnd to do the scrolling and let the mouseUp 
in the control handle taps. The mouseUp is paired with a mouseDown and 
only triggers a tap if the vertical difference is more than 10 pixels.


There may be something odd about the Android implementation. You might 
consider submitting your stack to the QCC, it was a puzzle for me too.

CanCancelTouches Kills Mobile Scroller?

[Scott Rossi]

Hey mobile dev folks:

I'm wondering if anyone has come across an issue iOS issue of a mobile
scroller becoming non-responsive if its canCancelTouches is set to false.

I've been working with LC 6.5.2 and 6.5.1, and an xCode 7.0 build.  Things
run fine in the simulator.  However, when run on a device (iPhone4s with
iOS7), multiple stacks, including RunRev's original mobile scroller demo
stack, exhibit the problem.  As soon as canCancelTouches is set to false,
the mobile scroller stops working -- no scroll indicators, an no
scrolling.  Setting canCancelTouches  to true restores scrolling.

This would seem to be a blocking problem for handing touchable controls
within a scrolling group, so I wanted to find out if anyone has come
across this before, and more importantly, how to get around it.

I'm preparing to test LC 6.6.0 and xCode 7.1, but thanks in advance for
any suggestions/confirmations.

Re: CanCancelTouches Kills Mobile Scroller?

[Stephen MacLean]

Hi Scott,

While I haven't had any need to set that property, I've had to use on occasion 
mobileClearTouches. 

Typically when I'm doing something with an iOS control, it can get unresponsive 
and the only way to get the app responding again is to use that.

Not really sure why, so not sure what to report.

Bugs the living daylights out of me because it means you usually have to tap 
the screen again.

Not sure this helps at all, but they might be related?

Best,

Steve MacLean

RE: CanCancelTouches Kills Mobile Scroller?

[John Dixon]

Scott...

Can't really answer your question as it is asked... All I can say is that I 
always have

   iphoneControlSet scrollID, delayTouches, true
   iphoneControlSet scrollID, canCancelTouches, true

bothe 'delayTouches'  'canCancelTouches' set to true and never seem to have a 
problem with scrollers.

Mobile Scroller with Snapping?

[Scott Rossi]

Has anybody been able to set up a mobile scroller with scrolling that
snaps to a predefined distance?

I have a set of icons in a vertical scroller which I want to snap to a
multiple of the icon height once the scroller completely decelerates/stops
dragging.  Using 5.5.1, the routine I built works fine in the iOS simulator
but intermittently fails on an iPhone 4 in that the snap doesn't always
occur.  The code is apparently executing correctly, both scrollerEndDrag and
scrollerEndDecelerate messages are being received, but again apparently
intermittently.

I'm trying to submit this week so am under  the gun time-wise.  Thanks for
any suggestions.
