If you set a background color or pattern that shouldn't happen.

Determining a scroll based on code unit offsets

2020-03-27 Thread J. Landman Gay via use-livecode

In our last episode, our heroine was trapped by the selection of a line 
containing metadata. The heroes of this group saved her. In all cases, 
scrolling the field was accomplished by using the "select" command to bring 
the line into view.


Alas, escape from one danger has led to another. The field itself must be 
inside an enclosing group so that it will scroll smoothly on mobile. She 
needs to translate the data from codeunits to a scroll position in order to 
set the group's scroll rather than the field scroll.


Each line of the data looks something like this:

1,103,7

While 7 is a line number, multiplying that by the textheight doesn't give 
consistent results due to line wrap. The first two items are codeunit 
offsets but there doesn't seem to be a way to translate those into pixel 
positions.


Our heroine is once again in distress, though as mentioned here, some of 
that may be due to the inability to reach the keyboard from 6 feet away, 
which presents its own positioning problems.

Re: Determining a scroll based on code unit offsets

2020-03-27 Thread J. Landman Gay via use-livecode

Oops. Not saved. It fails on larger offsets. Maybe I'm doing something wrong. Here's my longer
way, it could likely be optimized better. It does rely on a scripted field selection, and the
selectedChunk is passed to the handler:

on grpScroll pSelChunk
-- pSelChunk = selected field chunk: char x to y of fld z
put the num of words in char 1 to (word 4 of pSelChunk) of fld "tText" into
tNumWords
put the formattedtext of fld "tText" into tFText
put the num of lines in word 1 to tNumWords of tFText into tLineNum
put tLineNum * the effective textheight of fld "tText" into tScroll
set the vScroll of grp "tTextGrp" to tScroll
end grpScroll

Seems like there should be a better way.

Re: Determining a scroll based on code unit offsets

2020-03-27 Thread J. Landman Gay via use-livecode

Hm. My handler fails too on larger offsets but I think it's because there are lines above it
that have spaceAbove and spaceBelow attributes, and those aren't being taken into consideration
when multiplying lines by the textheight. I think Mark's example might work if formattedHeight
adjusted for that.

Hiding doesn't change anything but the visibility. If you need to change focus either use "go" 
or set the defaultstack.


The documentation in 9.5.1 says that hide stack is not supported in 64bit. What 
is the alternative for MacOS X 64bit to temporarily hide my application?


I think this is a documentation glitch. All the dictionary references in that last paragraph 
aren't showing up, so it isn't clear what the nouns are. But "hide" is still supported as far 
as I know. I think the missing references there are talking about QT commands.

So, have we all missed a clever and simple, non convoluted method of telling 
which cell in a scrollable, non editable table field has been clicked? Even if 
that cell is empty.


The table field is pretty rudimentary and so has limitations. For example, no messages are 
generated if a user clicks in a cell that is below the last text entry. Provided the field is 
full of data and user clicks on a populated cell, this seems to work:


on selectionChanged
  put "Row:" && word 2 of the clickline into tRow -- adjust for scroll here
  put "Col:" && getColumn(the clickH) into tColumn
  put tRow &cr& tColumn
end selectionChanged

function getColumn pClickH
  put the num of items in the tabstops of me into tNumStops
  put last item of the tabstops of me into tTabWidth -- in case we need to 
calculate it
  set the itemdel to tab
  put the num of items in line 1 of fld "tf" into tColumns
  if tNumStops < tColumns then -- add missing tabstops
put the tabstops of me into tTabs
repeat with x = tNumStops+1 to tColumns
  put comma & (tTabWidth * x) after tTabs
end repeat
  end if
  set the itemdel to comma
  repeat with x = 1 to the num of items in tTabs
if pClickH > item x of tTabs and pClickH < item x+1 of tTabs then
  return x
end if
  end repeat
  return empty
end getColumn

This is as far as I got (I need to get back to work,) but I think all it's missing is 
calculating the row offset if the field is scrolled. David accounted for that.

Re: Answer dialog enhancement...

2020-03-31 Thread J. Landman Gay via use-livecode

I had to create my own for mobile since the default didn't do what I 
wanted. I implemented it as a group. When the user hits the OK button it 
places the response in the dialogdata and sends a message to the card. The 
card has a handler that captures the message and gets the dialogdata to do 
what it needs. If the user cancels, the dialogdata contains "cancel".


I keep the group in an unplaced background, and when I need it I copy it to 
the card. When it's dismissed I delete it. That way I don't need to include 
it on all the cards. I trigger it with a command that passes any necessary 
data to the group as parameters.


I don't think it's possible to remove the answer dialog from an app, the 
last time I tried it reselected itself, so I just ignore it. Since I was 
using it on mobile this works pretty well, but on desktop it would be 
confined to the card rect. You could do the same thing with a stack, which 
would eliminate the need to copy anything.

Yes. That is easy enough. Turn on "Show IDE Stacks in List" from the
"View" menu and there are the Answer and Ask Dialogs.

Then you need to work out how the Answer command passes its data via
"the dialogData" property into order to create an alternative calling
routine that sets up the Don't Ask Again check box

You could copy the Answer to your own project  and in the Standalone
Settings switch to Manual Inclusions and exclude the Answer Dialog. Then
I believe the answer command will use the copy of the dialog in your
project. Then you need to add the button, change the resizeStack
handlers accordingly, script its show and hide, add code to get the
return value

AND remember to see if the dialog needs updates with each new release of
LiveCode.

That is why I asked if anyone has already done it so as to not re-invent
the wheel.

Re: Script Only Stack Properties

2020-04-04 Thread J. Landman Gay via use-livecode

When a script only stack is opened, LC creates a temporary stack and plops 
the script into it. At that point its just like any other library stack. 
You could add images, controls, other scripts, custom props, anything. The 
only difference is that when the stack closes, the text of the stack script 
is written back to the file and everything else is lost.


I suppose you could put custom properties at the top of the stack script 
inside a comment block, and set them up normally by script when the stack 
opens.

I see where people get confused. When we talk about dimensions, for most 
people the “Physical” in  “Physical Dimensions” is implied, just like when 
Dad says, “Hand me the map”, what he really means is, “Hand me the plastic 
coated street and highway map of the state of California that we just 
purchased at the 7-11 10 minutes ago". We use these abbreviated forms of 
implicit communication because being absolutely specific about aspect of 
every object or idea we wish to convey would be impossible.


Put another way, a chemist might say, “when I heat water to 212 degrees 
Farenheight, the water boils.” Implicit in that statement is the fact that 
he is at sea level, that the water is pure, that he is on the planet earth, 
that the air pressure is at or near a certain level, etc. Every such 
statement contains the unspoken, “All other things being equal” clause we 
always unconsciously take for granted.


So when physicists call Time (or anything else) another dimension, they are 
pulling a kind of, "bait and switch”. They stop talking about “Physical” 
dimensions, and begin talking about something else, but they never warn us 
of this transition! Here’s why I do not believe there are any more 
dimensions in the classical sense.


If I alter one of the dimensions of a 3D object, I do not affect the other 
two dimensions. But if a alter time itself, I alter ALL of the other 3 
dimensions. Time is more like a modifier of the physical dimensions. (One 
could also argue that spacial dimension creates the effect of time.)


Think of it this way. If I could make time infinitely short, everything 
would be reduced to an infinitely small point, because for there to be 
anything else, an object could theoretically be at one point in space and 
not another, implying that at another time it could be at another and not 
the original point.


This is an effect bantied about when discussing traveling at near light 
speeds. Not only does time compress (it is thought) but so does matter. The 
implication is that if you could get everywhere infinitely fast you would 
already be there and so there would be no time. And no space for that matter.

Maximum field height?

2020-04-04 Thread J. Landman Gay via use-livecode

I have a field that reports a formattedheight of 125396. I want to extend it to full height for 
use inside an enclosing scrolling group. But when I try to set the height to the 
formattedHeight, I get an error: Value is not a number.


If I try to set its height in the property inspector, it reverts to 9,040.

Does it exceed some maximum? If I set a scrollbar on the field, it scrolls fine and includes 
all the text. But it won't expand to its full height for use inside a scrolling group, which I 
need for smooth scrolling on mobile.

Re: Maximum field height?

2020-04-05 Thread J. Landman Gay via use-livecode

Thanks guys. I did remember there was a limit but for some reason thought 
it was only for the width of a line. I've switched over to trying a group 
set as a container and setting the field itself to scrolling layermode. I 
haven't tried it yet on mobile but we'll see.

@Richard, when developing for desktop you don't need the enclosing group, 
but on mobile you do because acceleratedRendering only applies to groups. 
Without it you can't achieve smooth scrolling. I wish we could just set a 
field to scrolling layermode, it would sure make layout and resizing easier.

I think the new container layermode is supposed to help with this stuff. I 
haven't had to use it until now.

I see that method used in the Lesson on using a scroller for text as
well, but I've never understood why.  What is the advantage of putting
the field inside of a group rather than using the scroller with the
field directly?

I think Paul has the answer there: groups have limit of 32,767px on
either axis.  That's about 30' on desktop systems so generally useful,
but when using them to contain a field sized for long text it can easily
be exceeded.

If you're using a vScrollbar then no problem. But for swipe scrolling 
without a scrollbar, which is what mobile users expect, it's a different 
story. Android isn't as bad as iOS but there's a noticeable stutter on both.

On 4/5/20 1:12 PM, Richard Gaskin via use-livecode wrote:

Once I saw that the scroller works well on the field content I've been working with, I added a
routine to my mobile lib that automatically removes the vScrollbar from any non-editable field
that has one, and instantiates a matching scroller over it.

That's my standard procedure too, unless I'm using a pseudo-scrolling handler that allows
pushing up or down on the field on desktop. It's basically a simulation, but for quick access
during development it's faster to just use the built-in scrollbar.

So yes, I'm using the field directly with no enclosing group, but no, I don't use the desktop
scrollbar on mobile; the scroller overlay does a good job of tracking the user interaction,
with the appropriate endpoint indication and all, and scrolling the field in response to the
scroller's messages has worked well.

I just released an app using this method and on iOS the stutter is quite noticeable, as well as
on Android devices with slower CPUs. It's okay for short text, sort of (though there's a brief
jerk) but for anything longer it fails. Up until LC 9 it was possible to set the field to use a
scrolling layermode in the property inspector, but that's been removed. You can still set it by
script, but it has no effect (and probably never did) and the engine defaults to dynamic
layermode instead.

While you're at it, it may be worthwhile turning the scrollbar of the field off and having your
scrollerDidScroll set the scroll of the field directly, with no enclosing group at all.

As above, that's what my previous app did. I'm going to change that for the next update, as it
looks unprofessional.

If it works as well for you as it's been doing for me, it saves me another test and gives
confidence to others that actually development with LiveCode isn't nearly as cumbersome as that
Lesson on scrolling fields suggests.

Well, basically the lesson is correct. I wish it weren't so. But if you only use a few fields
with short content, your easier method is probably passable. My previous app has a field whose
content is almost always less than the field height, but only extends beyond that for a few
lines occasionally. For something like that, I'd probably skip the group. If you feel like
experimenting, try a field sized to a mobile screenrect with 50+ lines of wrapped text. Do it
on iOS if you have one of those phones; the simulator won't give you the same response.

is wrong, the field inside the container group uses dynamic layermode. Scrolling layermode 
doesn't get applied to fields. We'll see if this works when I'm far enough along to build a

1. xTalk features just don't work, or work totally inadequately (e.g.
scrolling fields).


Somewhat true. LC made a start by adding widgets you can drop onto the 
stack to create native mobile buttons and fields, but I'd like to see 
regular LC controls magically change to native mobile controls much as the 
Mac, Windows, and (sort of) Linux appearances do. That would make a world 
of difference.


But there are features on mobile that don't exist on desktop. LC has 
provided for things like Android toasts and iOS popups. These things are 
one reason the language can't be entirely universal; mobile requires a 
different feature set. But it would be great if a scrolling field would 
just be a scrolling field everywhere. On the other hand, mobile lets you 
scroll all sorts of things (images, carousels, etc.) so we'd still need our 
mobile scroller anyway.



I agree it could be easier, but it isn't impossible. But parity wherever 
possible would be my first choice in what I'd like to see improved.




2. Failure in cross-platform equivalence.


If you mean mobile equivalence, Android is catching up quickly, in part 
because of the FM initiative. I appreciate that. iOS is pretty well covered 
for the most part. Some folks mentioned the issue of branching for 
different mobile platforms but that doesn't bother me much. We have to do 
that sometimes for the three desktop platforms already. The features that 
both iOS and Android do have in common use the same code and syntax.



The other two are, I suspect, not truly solvable.

3. It's not "Live"Code. Developing for Mobile gets you back into the
horrible edit - compile (i.e. build a standalone) - test cycle.


Yeah, this is a pain. I'm not sure there's any way around it but the 
addition of remote debugging has made it far easier. For a long time I felt 
like I was back in 1998 where I had to sprinkle "answer" dialogs all over 
the place just to know what my variable values were. There are some tricks 
though that help. I created a generic launcher app that loads my working 
stack so there's no actual compile required. I can't do this for complex 
apps, but I can do it for testing pieces and bits that will eventually go 
into the main app later. For simpler apps, the entire stack can be tested 
pretty easily this way.




4. You still need to deal with the ugly issues of the SDKs and the
app-store  requirements.


For me this is the hardest part, way worse than developing the app itself. 
It's also why I'd much rather deal with Android than Apple. Google is 
pretty easy to deal with. Apple is a constantly moving target with a 
rollercoaster of requirements, not to mention the profiles and certificates 
and what seems to me to be an unnecessarily complex review process.


However, if you are just developing for yourself or a few other people, you 
don't have to mess with either app store. Android apps can be freely 
distributed to anyone by any method and you don't even need a Google 
account. iOS apps can be distributed to a few people as "testers" without 
going through their byzantine submission process, though you do still need 
to mess with their account, certificates and profiles.


I'm thankful that the LC team keeps up with Apple's constantly changing 
requirements. Apple doesn't seem to value their developers much.




So, for me personally, even if LC Ltd. could fix (1) and (2), I would
still not even bother trying to build a mobile app; it's just not worth
the hassle or the learning curve.


It isn't such a steep learning curve as you'd think. One test app will 
probably get you going. If I were starting over, I'd start with Android 
because it's so much more flexible. The hardest part there is just making 
sure you download the right SDK and Java version.



OK - that's an easy decision for me - I don't do this for a living, I do
it for fun. And right now Mobile development is no fun.


It could be improved, but it isn't not-fun. It's just software development 
like anything else.


As you say, I don't have much choice. I haven't really done a desktop app 
for a couple of years now, clients want mobile and mobile only. Desktop 
apps are going away. My main client deals in university software and half 
the students don't even own a computer any more, they do everything on 
their tablets or phones. I found that LC Android apps also run pretty well 
on Chromebooks, even though LC doesn't officially support those, and if 
students own a laptop at all, it's likely to be a Chromebook these days. 
They're cheap and fast and essentially immune to malware.


When we only distributed desktop apps, students complained that they had to 
go to the school's computer lab because they didn't have a laptop.




The downside is, I've all but run out of reasons to develop in LC.


That would be a shame. You already have the skills, and aside from a few, 
but not all, mobile controls, the rest of it

Touch messages already send duplicate mouse messages. In fact, unless you

But, afaik, it's not just scrolling fields; aren't there also issues with keyboard input
requiring you to scroll / move the field to remain visible,

That was fixed recently with mobileSetKeyboardDisplay.

Also, besides mouse events working on both mobile and desktop, there is automatic conversion of
option buttons to native mobile equivalents and cross-platform equivalence for browser widgets.
Other widgets like navigation bars and segmented controls can change between mobile platforms
by altering some of their properties, and the switch button has a handy "theme" property that
lets you do that with a single property setting. I wish they all had that.

We also have Android native fields, and iOS native fields and buttons (where's my Android
button?) which can be dropped onto the stack, though on desktop they are placeholders.

And the fact that mobile-specific commands each need to be wrapped inside an environment-check to keep from throwing an error in the IDE.

That's easy to fix. I have standard library handlers that create scrollers, input fields, etc.
and at the top of each one I put "if the environment <> "mobile" then exit thisHandler". That
way I can script everything normally and if I'm not on mobile the command is ignored so the
scripts don't need to branch for things like that.

On the other hand, a frequent request has been for the LC engine to ignore mobile commands if
we're in the IDE. So there's that.

4A. SDKs and the build environment. Just horrible; when I tried this a few years ago (for Android) it took me
days of frustration and guesswork to get a working SDK, and get it connected to LC, and to try to get a
simulator to work properly. Including choosing (I think it "device type") from a long drop-down
list of devices I didn't own. I picked at random - and was told either that it was "unavailable" or
"will be slow - suggest you try a different device". Well - they were right about that - the
simulator was S...L...O...W.

You're right, the Android emulator is horrible. I stopped using it early on. LC recently added
support for x86-64bit specifically so we could use the faster version, but I found it much
easier to just cable my phone to my Mac and use the real thing. It's quick and painless.

I never did get round to trying for IOS, because everyone said how much harder
it was than Android :-)
I've found the iOS simulator to be very good, on the other hand. It accurately represents what
will happen on a real device, including all the bugs I introduce. It does require a bit of
setup -- downloading gigabytes of XCode is a time suck -- but once set up it performs well.
However, I've found switching between different versions of XCode/LC to be cumbersome. I'd like
it if LC could make the process easier, maybe by issuing shell commands behind the scenes so I
don't have to.

4B. App store issues. Never got that far - though it sounds like it's pretty
annoying.
Build for a few people (and sidestep the store) - seems to be possible, but not
clear how easy it is.

Apple makes it painful to submit to their store, but if all you want is to generate some
certificates and profiles so you can distribute to a few people, more than half the pain is
avoided.

Private Android distribution is a piece of cake. Build the app, send it to someone. The only
caveat is that the user must enable a setting on their phone that allows them to accept apps
that are not downloaded from the Play Store. Newer Android devices will ask the user if they
want to do that, older ones require the user to go into Settings to flip a switch.

Thanks for the reply - it has stiffened my resolve to have another go !!

I'm so glad to hear that. :) Ask us if you get stuck.

Re: Video format for mobile

2020-04-08 Thread J. Landman Gay via use-livecode

If that's true, I'm in trouble. There are a lot of these videos.

I just made a quick test app and ran it on Android. I get a blank mobile player displaying a
completely black rectangle. The script loads the URL from my server, waits for a
playerPropertyAvailable "duration" property to be received, and then starts to play. The video
is about a minute and a half long, the duration is never received, and after about a 30 second
wait I get the playerFinished message.

A quick web search verifies what Colin said, an .mp4 with H.264 and AAC is pretty much standard
these days.

Not sure where to go from here but I need a solution.

my guess is the LC player does not have h264 codec. its a codec that
carries a license fee and agreement. I hope one day it can be included in
an indy license and maybe the CEF can be built with the h264 codec.

That would be really good for business.

I will try it on mobile when I get farther along, but for now I'd like to
debug on Mac during development. The LC player is blank when I set the
filename, presumably because it doesn't support QT either.

Re: Video format for mobile

2020-04-08 Thread J. Landman Gay via use-livecode

Not sure what you mean by "an existing app" but my test app uses mobileControlCreate to set up
a mobile player. When it accesses the video from my server, it's all black with no video or
audio, and the nonexistent playback quits a few seconds in.

I'm not sure whether these videos were created with streaming in mind. I vaguely remember we
used to need to set a "streaming" checkbox when creating a video. Is that still required?

The .mp4 file spec allows for 3 different audio formats. AAC, MPEG1-Layer1 and

I just made a quick video using each audio codec, and the only one that plays audio 
in LC is the AAC version (MacOS, LC 9.5.0). To make sure you’re video is the right 
format, download the sample stack in the bug report at 
https://quality.livecode.com/show_bug.cgi?id=21278 
. I know that video works, 
at least on Mac.

On MacOS. Quicktime is the default player on the Mac still today, but it’s not 
the same QuickTime from years ago that LC depended on. If “About QuickTime 
Player” shows version 10.5, you’re on the new one. QuickTime Player 7 uses the 
deprecated APIs.


I have QT 10.5 and it plays the video. Firefox does too. On Android, Chrome plays it. So it 
looks like LC mobile player could be the problem.


I downloaded the file from your bug report, set a LC player to the filepath on my Mac, and got 
the same empty black screen.

Is it all that tedious?

Yes, unless you have a simple stack with only a few controls. If you have hundreds of objects, 
dealing with each of them individually, even if it's only one line that calls a handler, is a 
tedious time sink.

Graham, experiment with fullscreenMode, which automates most of the process. It isn't perfect 
and you'll need to make a few adjustments for different screen sizes, but it's much easier than 
trying to adjust for every possible screen ratio. LC implemented this specifically to take away 
the pain as much as possible.

Your LC prefs are in your user library at /Users/name>/Library/Preferences/RunRev/livecode7.rev. I'm not sure prefs are related here though.


I'd first try removing the stored standalone settings, which are stored in the stack itself. 
Use the property inspector to check the custom properties of the stack. There should be a 
property set named "revStandaloneSettings". Try deleting that set and starting over.

Re: Video format for mobile

2020-04-10 Thread J. Landman Gay via use-livecode

I haven't actually tried either of those because 1) I can't expect users to fiddle with
hardware acceleration, and 2) there aren't any security issues, since (as I just noticed) the
player control in the IDE will play the video.

I thought it didn't work before because the size of the video is so large that all I saw was a
portion of the initial white frame; the controller and edges were far off the card boundaries.
Once I enlarged the card to something huge, I could see the controller and play the video,
which did work.

Since the test stack does not use acceleratedRendering at all, I don't think the bug Mark
mentioned applies, though who knows. I couldn't find a bug report.

I'm now wondering if the video needs to have a special setting for streaming. When I play it
with the LC player in the IDE, it starts up instantaly and plays. On Android, I see a black
rectangle with a controller that disappears after some seconds. After that nothing happens.
I've waited several minutes to see if Android was trying to download the entire file (which is
100 MB) but either I didn't wait long enough or it didn't work. So that's why I'm wondering if
the video needs to be specifically created with a streaming flag.

On 4/9/20 5:34 PM, Colin Holgate via use-livecode wrote:

create apps and convince users to download them (Apple gets their 30%

who have decided to opt in, download an app, and accept the app's

Here are some additional details. Seems like a good thing they are doing.

Hi Jacque

I noticed some very similar behavior to what you are seeing but only when 
acceleratedRendering is on. I could hear audio but the video was just white. 
Turning off acceleratedRendering fixed the issue for me. I found a way to 
resolve the issue in the engine. If anyone is interested it has to do with how 
the main surface view and the video surface view are layered. The same issue 
appears to impact the camera control and likely (untested yet) impacts the 
barcode scanner widget. I’m not sure if what you are seeing is related if 
acceleratedRendering is not true.

First up this morning I’m creating a recipe stack for this and another issue I 
found with android player then crating bug reports. If you would like to create 
a recipe stack to demonstrate your issue that would be helpful too. Perhaps 
attach to your own bug report and then we can determine if it’s a duplicate of 
what I’m seeing or something else.


Done: <https://quality.livecode.com/show_bug.cgi?id=22674>

Thanks Monte.

Good news! This is not a bug!

As of Android 9 clear text HTTP is disabled by default. This is much like the 
ATS restrictions on iOS. We probably need to add a way to configure this in the

advisable.

Changing your video url to https resoled the issue.

See

The bug was me. I didn't know about the HTTPS requirement, but in addition I had to add the SSL

You don't need XCode though, except to have it sitting on your hard drive with its command 
tools installed. Once that's done, you can ignore it. Use the Development menu to choose your 
test device, and then choose Test from the menu, or just click the Test button in the toolbar. 
(And make sure your stack is focused or nothing will happen.) As long as XCode is set up and 
green-lighted in LC mobile preferences, that's all you need.


If you want to use a simulator though, you do have to launch it from XCode. But then you can 
ignore it again.

Missed this the first time around. You can still do everything from LC, once you launch a

Then you can choose the simulator from the LC Development menu, hit the Test button and it

Okay I created a simple stack with one sub stack. In the card script of stack 1

open me
put the defaultStack & cr after msg
end openStack

I get:
stack "Untitled 1"
stack "Untitled 2"

It seems going,opening a stack sets the opened stack to the default… IF IT’s 
NOT ALREADY OPENED! If it IS, well then you are on your own. The defaultStack 
is the last stack opened. (I’m assuming it’s a normal stack and not a pallet or 
something else).

Now you would think at this point you can use topStack instead, but NAY! This 
script:

on openStack
put the defaultStack && the short name of the topStack & cr into msg
open stack "untitled 2"
put the defaultStack && the short name of the topStack & cr after msg
go me
put the defaultStack && the short name of the topStack & cr after msg
end openStack

produces:
stack "Untitled 1" Untitled 1
stack "Untitled 2" Untitled 2
stack "Untitled 2" Untitled 2

After I go me, neither the defaultStack nor the topStack changes! What is more, 
the untitled 2 stack still has focus!!

Just to be certain I disabled all my plugins and relaunched, same thing.

This CANNOT BE RIGHT! And if it is the expected behavior, it ought not be.

‘System’ and ‘Internal Speakers’ as outputs from the simulator.


Is this my fault or the simulator’s?

Re: Long Standing Issue with the defaultStack

2020-04-18 Thread J. Landman Gay via use-livecode

The stack style is important, its mode influences which stack is toplevel 
and default. A palette shouldn't be the default stack unless you focus on 
it, for instance.

Example:

MobileControlSet "rkWebView”,”https://www.apple.com”

I’ve recently bought Mobile Native Essential pack in a slightly desperate

name displayed, leading to very much deprecated names with spaces in them.

Switch - caused a (simulated) version of my app to seize up. As a test, I
tried to open a card containing just that one object and it zonked the app.
I will be reporting this, but of course wonder it it’s something I’ve done.

Outside the paid-for pack, I also have issues with the native button

choice of icons IMHO, and no apparent way of adding to them).

I don’t really want to moan but I would like to see some improvement. Is
this list a good place to discuss these issues?

You mentioned the iOS native button doesn't look right. If it makes you feel better, the

linesize to 1 and the round radius to 8. You can set the border color and the text color.


I use the same graphic for Android. Sometimes Android buttons have a fill color, sometimes they

Re: Widget Properties

2020-04-24 Thread J. Landman Gay via use-livecode

My suggestion was just to see what properties are available in the widget. But when I just
tried it, I see that it doesn't respond in the IDE, what you see is just a placeholder. You can
search for "ios native button" in the dictionary, where I see only two available properties:
enabled and label.

If the widget author doesn't support the rest of them, they don't exist. I do see that you can
resize the rectangle, but since I don't use the native buttons I'm not sure if the size will be
retained on an iPhone or whether it just defaults to the standard native size.

Typically only the properties that the author has supported will appear in the
property inspector.

2020-04-25 Thread J. Landman Gay via use-livecode

Don't despair, not all widgets are duds. I've used several with good 
success: the browser widget, spinner, tree view, switch button, nav bar, 
segmented control and probably some others I can't remember. Since each 
widget is authored by an individual, the properties they support vary but 
like any software, feature requests are considered.


In my case I usually can't wait for a specific feature so I use LC controls 
or groups that emulate the control I need. In my last project I created a 
navigation bar with LC controls but it was recently updated to support a 
feature I needed and now I'm using it again.

I notice in the Standalone Settings for iOS in LC 9.5.1, a button ‘Background
Execution’. If I click it, I get a warning that I don’t really understand which
suggests that LC doesn’t officially support the feature. I’m not even sure if
this feature is what I need.

You are probably running an older version of LC since that checkbox has been removed recently.
iOS now runs all apps in the background, much as Android always has, and if you use that
checkbox now the App Store will reject your app. The deal is, the OS will keep the app in the
background until it needs RAM for something else and then it dumps the app. There's no telling
when that will happen.

This came up yesterday in the forums. The poster wanted his app *not* to run in the background
after a certain amount of time. We get no messages once the app goes into the background, the
only message sent is "shutdown" when the app gets wiped by the OS. In the meantime, the app
becomes inactive if it isn't frontmost.

Other apps seem to be able to manage this better, so it seems there's something available that
LC doesn't support.

The imperfect workaround, such as it is, is to write everything to disk that the app might
possibly need if it suddenly stops. When it comes to the front again, reload everything and
carry on (you'll get an openstack message when that happens.) For example, if your app has a
login screen then you'd need to store the credentials on disk and automatically log the user in
when the app restarts. Provide a "log out" button so they can quit on purpose; it would delete
the credentials from disk so they'd need to log in again next time.

Basically you have to save the user state repeatedly whenever anything significant changes, in
case the app goes dormant.

In the middle-end part of the string I have “(x)” where x represents some

it could be (4) or (10) or (5) etc.

I just want to replace the number inside the () with whatever other number I 
need to.


If there is only a single instance, you could:

  replace "(x)" with "(" & someNumber & ")" in myString

If there is more than one instance then each instance would need a unique character inside the 
parentheses.

FormattedHeight

2020-05-01 Thread J. Landman Gay via use-livecode


Is the formattedHeight of a group broken for anyone else? LC 9.6dp4 (and 
possibly dp3).

I'm a little frantic.

Re: FormattedHeight

2020-05-01 Thread J. Landman Gay via use-livecode

Yes, that seems to be the problem. I have a long text field that exceeds the maximum. There's
an enclosing group to be compatible with acceleratedRendering on mobile. The same setup is used
for all the field/group combinations in the stack and they all work except this one, but the
others are all shorter.

I set the inner field to its full formattedHeight inside the group, which is shorter. The group
has a behavior that scrolls the content.

I discovered today that if I set the behavior on the field instead of its enclosing group, I
can make it scroll. But acceleratedRendering on a field is jerky and doesn't work very well on
mobile. I can't break up the text, it has to be all one block. I have tried setting the group
to container layermode without success.

If you're wondering why the text exceeds the maximum, this is for a mobile app and there is not
only a lot of heavy formatting with large headings and spaceBelow, but the text size is largish
so that it is readable on a tiny phone. That makes the pixel count pretty high.

I only have a very short time left to solve this.

There was, only I can't remember the details either. But I do remember that there was a fairly 
clear division between the stack content and tacked-on engine, and if you knew what to look for 
you could delete the engine part in a text editor and end up with a working stack.


The thing I can't remember is what to look for as the delimiter. But it would probably be clear 
if I could find one of my old HC standalones, which I can't.

That's what widgets are for. There are native fields and buttons, though some are still

Building a standalone warns about duplicate stacks

2020-05-06 Thread J. Landman Gay via use-livecode

When building a standalone (for mobile in this case) I'm getting repeated messages about stacks 
already being in memory and asking me what to do with them. Since I have a lot of included 
stacks I need to make a decision a dozen times. This is different from all the "open*" 
messages, so that workaround won't help.


It doesn't happen when I use the Test button to install directly to my phone. I think this is 
new behavior. Bug?

Re: Building a standalone warns about duplicate stacks

2020-05-07 Thread J. Landman Gay via use-livecode

Thanks, that explains it. I've incorporated Trevor's DataView and it has 
about 10 stacks in use as behaviors and libraries. To add to the fun, I'd 
forgotten that building for mobile no longer disables desktop platforms so 
I didn't think to disable them manually, and the standalone builder put up 
that annoying dialog 50 times.


Surely the warning shouldn't apply to the SB. It knows you just want your 
working files back.

Jaque,

I’ve seen this when building standalones with stacks that are using library 
stacks, and the same library stackflles are included in the standalone 
build. Apparently the included stacks are opened during the build process, 
thus colliding with the library stacks already in memory. If this is the 
problem, I suppose a workaround would be to stop using the library stacks 
before running the build process.


Hope this helps.

2020-05-19 Thread J. Landman Gay via use-livecode

I have a tall field inside a shorter group that uses a mobile scroller. A behavior assigned to 
the group handles the scrolling and checks for swipes by capturing mouseDown and mouseUp to 
determine touch locations so it can calculate the direction of the swipe. This works on Android.


On iOS I do not get mouseUp or mouseDown messages when swiping horizontally, though I do get 
scrolerDidScroll when swiping vertically. But since the group is exactly as wide as the field 
it encloses, it does not scroll horizontally and so no scrollerDidScroll message is sent. I 
also do not get scrollerBegin/EndDrag, touchStart or touchEnd, or any other message I can think 
of to track a horizontal swipe. I do get mouseUp/Down when tapping on the scroller but that 
doesn't help here.


How would I detect a horizontal swipe on a non-moving scroller? The user can't 
navigate without it.

Re: Mouse messages in scrollers

2020-05-19 Thread J. Landman Gay via use-livecode

Would the problem be due to the settings for canCancelTouches and delayTouches? What are the 
defaults? And what behaviors do they control exactly? I can't quite figure out what the 
dictionary is saying.

2020-05-19 Thread J. Landman Gay via use-livecode

I'm doing something very similar but the problem is that I don't get any 
mouse or touch messages at all, which is why I'm thinking it must be the 
settings for my ios scroller.


Whatever the defaults are for delayTouches and canCancelTouches, I think at 
least one of them needs to be changed.

I’m using this script on iOS directly inside a LC field object in order to

it requires a swipe on iOS which is what you are after. I don’t think it is 
responsive enough to do some of the fancy pushes that differentiate between 
showing and sending things. It has been a long time since I worked on this 
(and I chopped out a lot of code) so it is possible that I’ve missed 
something. FYI: the field is a “List” field.

Re: Mouse messages in scrollers

2020-05-21 Thread J. Landman Gay via use-livecode

It was "delayTouches" mostly. Default is true, I had to set it to false. I also set
canCancelTouches to false but didn't test how necessary that was. Default for that is also true.

This allowed messages to pass through to LC, but you had to very deliberately swipe, holding
down a moment so the mouseDown would fire. Brian Milby came up with a faster solution using
something like Jim MacConnell's suggestion -- make the contentRect wider than the group so that
a horizontal swipe triggers scrollerDidScroll. Lock direction to vertical to prevent wiggle.
That proved to be a the solution for a more natural swipe.

You have to branch for Android because it doesn't have a lockDirection property; for that OS
keep the contentRect the same width as the group. Mouse messages pass through to LC
automatically, which is good because the above two settings don't exist on Android.

Swiping is such a normal behavior on mobile, I'd like to see an easier method in LC to
accomodate all this.

You have probably already looked at these but here are (some of) the scroller
settings I use for the below-mentioned field:

mobileControlSet sScrollerId, "pagingEnabled", "false"

mobileControlSet sScrollerId, "decelerationRate", "normal" -- fast --iOS only

mobileControlSet sScrollerId, "canScrollToTop", "true"

mobileControlSet sScrollerId, "delayTouches", "false"

mobileControlSet sScrollerId, "canCancelTouches", “true"

Code-signed apk fails

2020-05-27 Thread J. Landman Gay via use-livecode

We're about to release an Android app. I've been signing it for development only and it works
well. Today I created a keystore "FPMobile.jks" in Terminal as usual.

As an aside, I got this in Terminal:
Warning:
The JKS keystore uses a proprietary format. It is recommended to migrate to PKCS12 which is an
industry standard format using "keytool -importkeystore -srckeystore FPMobile.jks -destkeystore
FPMobile.jks -deststoretype pkcs12".

I don't know if that's significant. I've ignored it in the past, so I went ahead and entered
the jks file in standalone settings. When LC 9.6rc2 asked me to locate the keystore during the
build, I was unable to select it in the file dialog until I chose "All files". That seemed to
work and the build finished.

At any rate the real problem:

The codesigned app fails to download files from the server. My error log shows that sometimes
there is no error at all but nothing is downloaded, other times the error is vague: "Invalid
URL:" with no URL indicated. The same script and URLs work in the IDE and in the apk when built
without the keystore.

I don't think codesigning should affect server queries but that seems to be what's happening. I
rebuilt the apk without any changes except to remove the keystore and it worked perfectly
again. Could TSNet be involved somehow?

I'm not sure where to look for the fault. Ideas?

did you already try to build the .apk without tsNet?  This way you could check 
if tsNET is involved.
You need to do the 2 steps before building the .apk
1. executedispatch "revUnloadLibrary" to stack "tsNetLibUrl"in message 
box
(btw. to load it again after building the standalone execute dispatch 
"revLoadLibrary" to stack "tsNetLibUrl" - no need to restart LC IDE )
2. if "Select inclusions for..." is selected, then deselect tsNET external in 
standalone settings.

Now build the .apk with the keystore.
If the .apk is able now to download the files although it is signed, then tsNET 
is involved.


I did this. Without TSNet, the apk works perfectly again. Now I wonder if I can do without 
TSNet for now.

I'm fairly sure that's the reason the file dialog didn't enable the .jks file, but the file
still works. I used Google's terminal command example, which creates .jks files, instead of
LC's example which I think uses .keystore. Next time I'll change the extension just to make
file selection easier.

Re: Code-signed apk fails

2020-05-28 Thread J. Landman Gay via use-livecode


Okay, here are the results of my tests, all done in LC 9.6rc2.

1. Keystore: FPMobile.jks, included TSNet: fails to download files
2. Keystore: FPMobile.jks, TSNet removed: works
3. Keystore: FPMobile.keystore, included TSNet: works

So TSNet doesn't like "jks" extensions, which is the file extension Google suggests. But I am 
baffled why a keystore would affect TSNet at all, not to mention it only prevents file 
downloads. The user can log in normally, make php queries to the server and get replies, the 
only thing that fails is actually downloading files.


Panos, is this bug-worthy? Or is it a documentation thing?

Hello Jacque,

I did a quick test, I put this in a button:

get url "https://google.com
"
put it into fld "url"

and signed the .apk with a release.keystore, and it works as expected for
me. The stack includes tsNet - I used LC 9.6 RC-2 for this.

Could you file a bug report with a recipe about this issue, and attach your
stack (or send it to me directly if it is confidential), so as we
investigate?

Kind regards,
Panos
