Re: Single File Deploy on Windows?

Can an empty file placeholder be created within preOpenStack, then extract
the real DLL when it is really needed?

Re: Gradients with transparency?

[Terry Judd via use-livecode]

Thanks for all the responses. I really wanted to use a graphic rather than 
importing an image for all the reasons that Scott mentioned. Mark’s method 
works of adding an alpha value to the ramp settings of the fillgradient 
property of the graphic works perfectly so there is a (relatively) simple 
solution available. I just need to make sure that I remember it for next time 
as well ;)

While we’re on gradient properties, does anyone else ever have problems getting 
the backgroundColor gradient setting window to show up? Unless you have a 
pretty big screen (I’m working on a 13 inch Macbook Air) the properties palette 
is so wide that the settings window can open off screen, making it 
inaccessible. If you close the properties palette, open it again and move it so 
the right edge is clear of the right edge of the screen then you can usually 
get the settings window to show.  But not always.

In LiveCode, there is another way to do this:

1- Import an Image without Transparency... or
create a snapshot of a group, vector graphic,
field, or any other control inside the card.

2A- Import a transparent PNG... or
2B- Take a snapshot of a vector graphic that
contains a Green to transparent gradient

For example:

on mouseUp
import snapshot from grc 1 with effects
end mouseUp

3- Put that transparent PNG on top of
the image without transparency...

4- Run this script from a button
to create a mask from PNG...

on mouseUp
set the locklocation of img 1 to true
import snapshot from img 1
set the loc of last img to the loc of img 1
delete img 1
-- after deleting img 1 (an image without transparency),
-- then img 2 (a transparent png) becomes img 1

crop img 2 to the rect of img 1

set the width of img 1 to the width of img 2
set the height of img 1 to the height of img 2

set the alphadata of image 2 to the alphadata of image 1
end mouseUp

Re: Negative Numbers and NumberFormat

[hh via use-livecode]

> Bob S. worte:
> I have a function for calculating the difference in time

Then you mean -(01:00:00) and not (-01):(00):(00), quite different.

AFAIK most languages do such time evaluations as follows
1) compute the time in seconds,
2) convert its absolute value to time format, and
3) if negative, put "-" before the formatted time.
That is, the whole display is not an immediate result of setting the
number format.

> You should rather say the number format determines the num of DIGITS.

That's what you wish to have (good idea). But it's not like that, its
the length of the number as string. You gave the proof yourself.
It's the same with the number formats from format(). Probably LC uses
internally format() for its numberFormat.

Re: Negative Numbers and NumberFormat

[Bob Sneidar via use-livecode]

The time format is irrelevant. It just so happens I have a function for 
calculating the difference in time, and when the first character is a - I know 
the end time is earlier than the start time, which was what I was checking for. 

And I think you are mistaken. numberFormat sets the format for numeric values, 
not just any characters. You should rather say the number format determine the 
num of DIGITS. Signage is an acceptable part of a numeric value. A dollar sign 
or a comma for example are not. 

Still, if everyone expects that set the number format to "00"; return 0-1 
should return -1, well then that's how it should be.

Long-term dream:  I would LOVE to see some way to embed externals within 
the executable file the way SuperCard does (no, SC doesn't use the 
resource fork; never did, everything is mapped in its data fork).  I'm 
not sure why we can't, since AFAIK the code within a DLL is what's 
important to LC, not necessarily that it exists in a physically separate 
file, no?  I long to be able to return to truly stand-alone standalones.


Short-term reality: You can download via HTTP/HTTPS using only libURL, 
no externals needed.  HTTPS will require the revSecurity DLL, but 
conceivably (as I've done on one project) you could download that via 
HTTP and then use it for anything needing HTTPS.


All that said, I think I've given up on the dream of stand-alone 
standalones, and have gotten back to finishing my installer. Drag.  I 
used to love sending people a single file they could just unzip-and-go.

The zeros in the number format determine the num of characters

Also we have -0 = 0. So what about "-01:-00:-00" ??

Re: Script to find bottom of lowest field

A sneakier way would be to select all, group them, then get the bottom of the 
group, then ungroup them again. Account for group margins (2 or 3 pixels or 
something). If there are other objects of course that won't help you.

 Put the max (tmax,the bottom of field I) into tMax
End repeat

Create field
Put it into tField
Set the top tField to tMax + 20

RE: iOS app rejected five times because of background audio setting

I just looked at the info.plist from my last app that Apple approved.

1) The UIApplicationExitsOnSuspend key is not there.
2) the UIBackgroundModes key looks like what you see.
UIBackgroundModes
 
 
 

What does your info.plist in the app look like?

OPTION 2: You bumped up against an less than expert reviewer. If your plist
looks correct then challenge them. I have done that in the past when I was
sure they were wrong and they acquiesced. If that does not work then go to
arbitration.

I feel your pain... Let us know how it ends.

Thanks for the info, Ralph. I had figured out the exit-on-suspend issue
previously. In my last app submission, I completely removed the entire
section in the info.plist file which referenced UIBackgroundModes, but they
still rejected it on the same claim that background audio was enabled. This

this effectively defaults to enabling that function.

2) Do the "plist hack" as enumerated in my last email.
3) This is all I do and have never been rejected for the "Background Audio"

Subject: iOS app rejected five times because of background audio setting

I have gone back and forth with Apple five times in an attempt to get this
setting correct. I made the mistake originally of enabling the background
audio option in the iOS standalone settings area. I was trying to prevent
the app from exiting when the user switched to a different app. I know that
this setting solves that issue, but it also caused Apple to reject my app
because I was not including any background audio.

I have since realized that the correct way to deal with this is to modify
the "exit on suspend" clause in the livecodescript file. But after creating
a new standalone and submitting it to Apple, they keep telling me I am still
referencing the backgroundaudio option. I tried making changes to the
info.plist and settings.plist files, but I can't seem to get this right.

I just downloaded a fresh copy of LC 9.0 and created a new standalone. 
When I look at the info.plist file in the standalone, this is what I find:

UIBackgroundModes
 

 


Is this correct? Is this the way the code should read when the background
audio option is not being used?

Thanks for any help with this,
Richard Miller

RE: iOS app rejected five times because of background audio setting

[Ralph DiMola via use-livecode]

Richard,

Been down this road. Ticking the "Background Audio" option sets
UIBackgroundModes key to "audio" as well as setting
UIApplicationExitsOnSuspend=False to keep you app active. If you are not
actually playing background audio then you will get rejected. The way to do
this is to edit the app.

1) In Tools/Runtime/iOS... set all the folders to read/write.
2) Edit the setting.plist in each of the folders and change
UIApplicationExitsOnSuspend key value to "False" (or like I do...delete the
key all together) 

That's it! Apple will not complain. If you need to have some apps with it on
and some with it off then make a copy of the app and change the
setting.plist's in the copy.

I only change the devices(only 2) and leave the simulators as is (I have 5
of them). If I want to test this behavior I just put the app on a device.

The problem, such as it is, is that the Unicode specifications have
128 * 8703 slots for glyphs (= a big number my mind cannot cope with)

glyphs a go: hence 8703 buttons.

Of course I could be racist and leave out the Chinese ideograph slots
(= about 70%) . . .


You'd probably be okay with 8703 buttons (were there not a co-ordinate 
magnitude limit), but certainly not with 128*8703 buttons.


Oh: I am perfectly capable of pumping out 8703 buttons, that is NOT the 
problem.


The problem is to have them placed sequentially one above the other in a 
"monster list" grouped into a 700 pixel high group with
a vertical scrollbar: even that, as such, is not the problem: the 
problem is thatthere is no way I can stack those buttons up

vertically prior to grouping them.

128*8703 not necessary at all (quite apart from the fact that I'd be 
even more out of my box

than I am already to contemplate that).


To give some context...

Each button takes up at least 128 bytes in memory, so:

  8703 buttons is about 1.4Mb - which isn't too bad

  8703*128 buttons would be about 150Mb - which is substantially more

Admittedly, neither of these will 'break the bank' in terms of memory 
availability, even on machines of a G3 Mac vintage, however just 
storing the representation of such things in memory is not the only 
issue. The engine has to do things like:


  - render all the controls on the card

  - perform hit testing when the user clicks or interacts with the card

  - search for controls when you reference them in script

Rendering requires a linear back to front scan of each control, 
painting each one which is within the visible rect of the window the 
card sits in. This means that if you have 8703*128 buttons it will 
need to perform that many steps to render. Additionally, whenever a 
small amount changes, it needs to do this again - as any one control 
*could* have been moved or intersect with the area which has changed 
(and thus require rendering).


Hit testing is similar, although the process is from front to back, 
and stops as soon as a control says it is the target of the mouse / 
user interaction event.


The third case, is the killer though. Looking up a control by name or 
by later requires (on average) number of controls on card / 2 steps to 
perform. If you use the (short) id, then there is a per-stack cache 
which makes the lookup take 1 step if it has been looked up before but 
the normal number of steps if it has not.


In general, we'd never advise using so many controls on a single card 
- and a data-oriented approach which is what others have suggested is 
generally the best approach in this case. i.e. Update the content of a 
small set of buttons as the user browses through the list.



I wonder if that limit is "cast in stone" or the Livecode people could
expand it?


Currently engine controls are limited to 16-bit quantities for 
co-ordinates - which means a range of -32768 to 32768. The underlying 
rendering library we use (libgraphics), however, uses floats (32-bit 
real numbers which given an integer range up to around 2^24). So, 
updating the engine to use floats or similar in its co-ordinates for 
controls is certainly possible, just not a task we've undertaken yet.


Warmest Regards,

Mark.



Best, Richmond.

Re: Gradients with transparency?

[Scott Rossi via use-livecode]

The thing about using a graphic gradient (as opposed to an image) is the 
graphic is infinitely more flexible:
- variable size (no loss of quality when resizing)
- variable colors
- variable transparency

As far as exporting goes, last I checked, I don’t think ink effects export 
intact, even when using “with effects” in the snapshot syntax, so if you can’t 
get the visual result you want with the default ink, you may need to export a 
snapshot of the region of the card you need.  Maybe support for exporting inks 
has improved recently (though in my quick dp4 test, exporting to the desktop 
crashes).

Hi.

Hmmm.

When you say "...the sign takes up one of the digital " does this make it
better or worse:

   set the numberformat to "00"
   put -1112 +0 & ":" & 0 +0 & ":" & 0 +0 

or going the other way, with your top snippet, did you expect:

-01:00:00

Negative Numbers and NumberFormat

[Bob Sneidar via use-livecode]

Was anyone aware that the sign takes up one of the digital in number format? 
For instance, 

set the numberformat to "00";put -1 +0 & ":" & 0 +0 & ":" & 0 +0
returns:
-1:00:00

but 
set the numberformat to "00";put -12 +0 & ":" & 0 +0 & ":" & 0 +0
returns:
-12:00:00

Does no one else find that odd??

20,000 "LIKES" - Richard!
You have expressed so well my feelings that I couldn't find the words for.

[rant]
The power we have in this tool [Livecode] cannot be overstated.
We have to remember it's "just" a tool-kit and there's a lot of stuff
that's already pre-assembled. And the rest can be hand-rolled given enough
desire. But we're also expected to put in some work to make it so.
And the fact that it ALL is an illusion cannot be ignored.  (don't take my
word for it, ask your local guru)
Sometimes an illusion of an illusion in the illusion. So that's my
allusion.

software at the speed of thought, indeed.

Personally I'd fake it:

I'd set up a gradient with one end being transparent in my graphics 
weapon of choice (GIMP) and save it as a PNG image,
import it and overlay it on top of your content, then make sure you 
group it with your content before you do an


export from group "JazzyGradient" to file "JazzyGradient.png" as PNG

Re: Cheesed off by 32xxx

[Richard Gaskin via use-livecode]

One of the beautiful things about making GUIs in LiveCode is that we 
generally get a very satisfying and immediate sense of physicality with 
the controls we're working with:  we envision the user interface, drag 
out controls to match that vision, and we have a one-to-one 
correspondence between what we're doing as developers and what the 
end-user is working with.


Most of the time this physicality lends itself to an uncommonly 
productive workflow.  I was talking about this with Trevor the other 
day, and we both agreed that the direct manipulation of controls in a 
"live" environment, coupled with a language that includes GUI controls 
as first-class citizens, is a big part of why we continue to rely on and 
enjoy LiveCode.


But from time to time, we find particularly ambitious GUI designs that 
become problematic within this paradigm.  Not impossible, but requiring 
us to abandon the comfortable sense of physicality to consider more 
traditional solutions.


As Mark Waddingham pointed out, the memory and CPU requirements for 
working with tens of thousands of objects can be onerous, in some cases 
perhaps prohibitively so.


That's part of the reason why most of the world solves GUI problems 
through radically different means than LC does.


LiveCode does such a good job of maintaining the illusion that GUIs are 
physical objects that we often take it for granted.  But in lower-level 
tools, you're required to be constantly aware that all of that is just 
an illusion - the structs, the buffering, the hit-testing, it's all 
abstraction that only appears physical at the very end of a very complex 
set of processes.


In lower-level languages, most of the time if it ain't on screen it 
ain't instantiated.  They don't even bother.  No need - no one can see 
it anyway.  They maintain just enough info to know when a control needs 
to be instantiated, and then do so only when it will be visible in the 
window.


The DataGrid is a good example of a middle path between the abstraction 
of lower-level languages and the physicality of LC controls:


You can have any number of rows in a DG, but truth be told the only ones 
that actually exist are the ones you're looking at.


Trevor has made very smart of use of fluid scrollBarDrag message to 
populate the visible portion of the group with the controls relevant for 
that scroll position.  Everything out of view doesn't really exist, at 
least not in terms of GUI controls.


It's a non-trivial task to effectively virtualize large numbers of rows 
and instantiate only what's visible on the fly.  He's done an excellent 
job of that.


In addition to being a very valuable part of the LC toolkit, the DG is 
also a reminder that with a little effort we can solve even big problems 
in LC, even though some of the bigger ones require us to set aside the 
perceived physicality and think about things in a more traditional 
computer science way.


I've found, as Mark confirms, that the coordinate space in LC is limited 
to about 32765 px.


Given the power of computers and the ease of using LC, we might 
sometimes see that as a constraining limitation.


But think about it:  at 96dpi that's just under 28 feet on a side - far 
larger than any monitor you can buy, which means far larger than 
anything any user could possibly see.


When we need to work in unusually large spaces, it becomes time to think 
in unusual ways.


By paging rendered elements, as the DG does, we can handle nearly any 
size of coordinate space.


It requires more work to think through a solution that makes sense for 
the design at hand, but just about anything you can imagine is doable, 
even if the worst that happens is that we have to think about solutions 
using methods similar to how the rest of the world has to deal with them.


In the case of the task at hand here in this thread, the solution is 
even simpler:  the DG already provides one way to virtualize large 
numbers of controls for us with minimal effort to use, and it may be 
possible to take advantage of the flexibility of LC fields, with their 
excelling buffering, to do that as well.


But even the in a worst-case outcome, where we'd need to figure out a 
paging mechanism from scratch. I wager that even though it requires more 
effort than just laying out tens of thousand of controls, it can be done 
in LC far more productively than one could do in just about any other 
GUI toolkit.

Re: OMG WTF detailed files BST?

[Ben Rubinstein via use-livecode]

The plot is slightly thickening. I restarted the VM, set the date+time to not 
adjust for daylight saving, restarted again. This removed some 30,000 images 
from the list with allegedly modified timestamps; the ones that were no longer 
consider to have changed were - in some year or other - modified between late 
march and the end of September.


I've now switched the 'adjust' setting back on, restarted the VM again, and 
await tomorrow's report with interest.


(In the meantime I've asked the clients IT dept what the server in question is 
running, but on the whole they tend to be very unresponsive... sigh.)

Therefore, some more precise details of the setup your app is running on is
probably
the best thing to try and get now - i.e. the details of the network share and 
how
it is configured in the VM.

Yes the color values you specify for gradients can have an alpha 
component. For example:


  0.5,255,0,0 -> at half way through the gradient, the color should be 
solid red


  0.5,255,0,0,127 -> at half way through the gradient, the color should 
be 50% transparent red.

Gradients with transparency?

[Terry Judd via use-livecode]

Is it possible to have a gradient with one of its end-points being transparent 
instead of a solid colour?

I want to overlay a graphic with a vertical gradient that blends from 
transparent to white to give the effect that the underlying content is fading 
out as you move down the screen. I’m able to achieve this effect using a black 
and white linear gradient in combination with the blendScreen ink but I need to 
be able to export the object (gradient plus underlying controls) as an image 
keeping the effect intact. When I export it now the ink effect is lost.

  8703 buttons is about 1.4Mb - which isn't too bad

  8703*128 buttons would be about 150Mb - which is substantially more

Admittedly, neither of these will 'break the bank' in terms of memory 
availability, even on machines of a G3 Mac vintage, however just storing 
the representation of such things in memory is not the only issue. The 
engine has to do things like:


  - render all the controls on the card

  - perform hit testing when the user clicks or interacts with the card

  - search for controls when you reference them in script

Rendering requires a linear back to front scan of each control, painting 
each one which is within the visible rect of the window the card sits 
in. This means that if you have 8703*128 buttons it will need to perform 
that many steps to render. Additionally, whenever a small amount 
changes, it needs to do this again - as any one control *could* have 
been moved or intersect with the area which has changed (and thus 
require rendering).


Hit testing is similar, although the process is from front to back, and 
stops as soon as a control says it is the target of the mouse / user 
interaction event.


The third case, is the killer though. Looking up a control by name or by 
later requires (on average) number of controls on card / 2 steps to 
perform. If you use the (short) id, then there is a per-stack cache 
which makes the lookup take 1 step if it has been looked up before but 
the normal number of steps if it has not.


In general, we'd never advise using so many controls on a single card - 
and a data-oriented approach which is what others have suggested is 
generally the best approach in this case. i.e. Update the content of a 
small set of buttons as the user browses through the list.



I wonder if that limit is "cast in stone" or the Livecode people could
expand it?


Currently engine controls are limited to 16-bit quantities for 
co-ordinates - which means a range of -32768 to 32768. The underlying 
rendering library we use (libgraphics), however, uses floats (32-bit 
real numbers which given an integer range up to around 2^24). So, 
updating the engine to use floats or similar in its co-ordinates for 
controls is certainly possible, just not a task we've undertaken yet.


Warmest Regards,

Mark.
