Re: Revisiting Lock Screen

[Craig Newman via use-livecode]

Bob.

I have no idea what you are facing with such a basic issue. To be sure, please, 
somewhere in the stack you are having the issue, make a button and a field and 
run this:

on mouseup

lock screen  —comment out for the first run

repeat 3

put random(999) into fld 1

wait 20

end repeat

end mouseup



Do you see the two scenarios above working normally? That is, with the lock 
screen disabled, you see three numbers in succession, and with it enabled, you 
only see the last one?

Re: disabled buttons still receive events, they just process them, later?

[Craig Newman via use-livecode]

Mike.

In a new stack I placed a button with this:

on mouseUp
  beep 2
end mouseUp

If I click on the button I hear two clicks. I disabled the button and clicked 
on it. I enabled the button. No clicks. I did this all by hand. Did you?

Re: Nasty filter bug

[Craig Newman via use-livecode]

Brian.

So the inclusion of “[“ would have matched nothing in the original string 
""aaa[bbb””? That is, even though the bracketed string was not “closed” with 
“]”, did it try to find a string that began with “b”, failed, and therefore 
returned the original string untouched?

Re: Nasty filter bug

[Craig Newman via use-livecode]

Brian.

The original post tried to filter a string by filtering (without) that actual 
string, and was interested in why that did not yield empty. Intuitively, the 
result of such a filter operation ought always to be empty. The presence of the 
char “[“ is the “culprit”. That is as far as I took it.

Anyway, you state that the char “[“ is a regex special character, which 
explains a lot. The other two, “?” and “*” filter without issue, though, and I 
guess one has to be a regex user to see why.

I am not.

Re: Nasty filter bug

[Craig Newman via use-livecode]

OK, instead of working I did this:

on mouseUp

repeat with y = 1 to 255

put "XX" & numToChar(y) & "XX"  into temp

filter temp without temp

if temp <> "" then put y & return after accum

end repeat

answer accum

end mouseUp

There are two characters that prevent the filter command from doing its job: 
ASCII 91 (“[“) and ASCII 10, the return char.

Nope. Those two chars pass through the filter, er, filtered.

Again, I did not test the entire character set.

Re: Nasty filter bug

[Craig Newman via use-livecode]

I did not test the ASCII set exhaustively, but the culprit is the char “[“ 
(ASCII 91). Any other char (including “]”) in the string works correctly, that 
is, nothing is left after the filter command executes.

I do not know enough to say whether that particular char  does something to the 
filter command, which may use regex somehow in its inner workings.

Re: LockLoc and grab

[Craig Newman via use-livecode]

Aha.

I did not see that you meant a single button in its own group. But it would not 
matter if I did the same with a control within a larger group of controls. And 
it does not matter if the lockLoc of the group is set or not.

So is your question “Why does the control disappear when it is dragged outside 
the group rect?” In other words, "why does it not just keep going in full view?”

I am not sure, but maybe being outside its group means it is nowhere at all?

Re: LockLoc and grab

[Craig Newman via use-livecode]

David.

I could not understand your issue, so I made the controls you mentioned. The 
thing that matters is not the lockLoc property, but rather the “opaque” 
property.

A group of controls is just a, er, group of controls. The “group” itself can, 
however, take on a life of its own if, as in this exercise, something like the 
opaque property is set. In that case, dragging a control with a lower layer 
number will disappear behind the group rect, regardless of whether or not there 
is a child control in front.

Am I getting your problem at all?

Re: Application disappears unexpectedly (goes into background)

[Craig Newman via use-livecode]

Clicking on a titlebar sends no messages to LC, only to the OS, essentially 
saying “bring me to the front”.

The fact that all the card windows reappear when you do that seems very odd to 
me. If I hide a stack and then go somewhere else on my computer, that stack 
does not reappear just because I brought LC back to the front. Hidden stacks 
stay hidden until explicitly made visible, as they should.

Jacque’s  suggestion seems reasonable, but it seems like a long shot.

Have you tried restarting?

Can’t wait to hear how this (hopefully) resolves.

Re: Which is faster...

[Craig Newman via use-livecode]

OK, I see what you mean.

I set a custom property of the card to the array I used earlier. It takes 
almost no time at all to put the contents of that property into a variable. It 
is not relevant whether it is a script local variable or not.

Bottom line, I do not think it makes any difference whether one uses a custom 
property or a variable to hold data in terms of the speed in which that data is 
retrieved.

Typo in the last post. BOTH had 100,000 elements or lines.

Re: Which is faster...

[Craig Newman via use-livecode]

Anything to distract me from my day job.

An array with 100,000 elements and a variable with 100,00 lines take the same 
time to place into a field.

The only time that took a while was building them. Each took 10 milliseconds.

Re: greying out columns in a dataGrid

[Craig Newman via use-livecode]

Zyrip.

Almost, and very good, since I do not understand DG’s at all.

I changed your offering to:


on mouseUp

dispatch "DG_ColorColumn" to grp "datagrid 1" with "col 2", "211,211,211"

—srcCopy  —no such command

end mouseUp


on DG_ColorColumn pColName, pColor, yellow

   set the opaque of grp pColName of me to (pColor is not empty)

   set the backcolor of grp pColName of me to pColor

   set the ink of grp 1 of me to blendSrcIn

end DG_ColorColumn

Re: resizeControl wishes...

[Craig Newman via use-livecode]

Paul.

“reSizeControl” is a message. What I mean by that is if you are already running 
under script control, why do you need to send such a message at all? Can’t your 
handler do whatever you needed to if the user did the actual resize action?

Re: [OT] The Fall of the British Empire???

[Craig Newman via use-livecode]

“... the bulk of Europe used French as the common language.”

That is where the term “Lingua Franca” came from. Before that in Europe, which 
was the center of the universe, learned people used Latin. Just ask Newton or 
any cleric.

English took over when the world got smaller. The US was the "bomb" in 1945, 
(can’t wait to see how that comes back) and ten years later consumed nearly a 
third of the planets energy. That plus Rock and Roll made English the only 
language that made sense.

Still does.

Re: [OT] The Fall of the British Empire???

[Craig Newman via use-livecode]

I did not mean “British” English, just English. And true, the hegemony that the 
US had and still has on this planet, commerce, popular culture, sheer weight 
and all that implies, forced everyone else to learn English. The internet is 
the prime example,

Americans are smug in that we do not need to learn other languages, because 
everyone else speaks English. I am not sure I am proud of that…

Re: [OT] The Fall of the British Empire???

[Craig Newman via use-livecode]

Empires these days are strictly economic. In fact, it was always that way.

Forget California, which has the 6th largest GDP in the world. Texas and New 
York combined would also come in at #6, and just beat GB.

England was #1 until 1916, when guess who took over.

When the United States took over. 1945.

The only thing that remained is that the Lingua Franca of the world is English.

Re: What to set the clipboardData to for exchanging styled text with a 3rd party app

[Craig Newman via use-livecode]

Hi.

I always use the “htmlText”.

Of course this encodes the original text with HTML tags, so you cannot just:

set the clipBoardData to the htmlText of fld 1
set the text of fld 2 to the clipBoardData

you have to:  set the htmltext of fld 2 to the clipBoardData

Re: Oddity in 'currentCard' function?

[Craig Newman via use-livecode]

Paul.

Having a more complete description seems right to me. You are essentially 
saying that if you use the moniker “the currentCard” that LC should know what 
you are intending, the is, the current “card”, and not the current “something 
else”.

It has to be one of those cases where, as Danny Goodman once said, “If a line 
of code seem like it ought to work but does not, try using a “do” construction 
to force another layer of resolution;

on mouseUp
put the currentCard of stack "Untitled 1" into tCardName

do "set the myProperty of" && tCardName && "to tValue"

end mouseUp

This works, and shows that the referencing of these sorts of things in LC, like 
in HC, is not quite as they read like.

Re: sort bug

[Craig Newman via use-livecode]

Bob,

If you remove the “numeric” the result is “2,3,4,6,a”.

To me this implies that ASCII values are used as the sortKey. But that begs the 
issue why, as in your post, with “numeric” included, the “a” appears first. 
What makes the “a” a lower "numeric" value than “2”?

Re: Sort bug and also multilevel sorting

[Craig Newman via use-livecode]

Neville.

My example was only to show that the sort command still maintains the ability 
to accept concatenated sort criteria. This allows a single line of code to do 
the work, and obviates the need for multiple sorts.  In that sense it was a bad 
example to use character "places" in a string. This would not be an issue when 
using an explicit delimiter of some sort, typically what any sane coder would 
automatically do.

Padding with zeros or spaces is the sort of kludge even I would blanch at.

I do not have your original data. But try using “&” instead of “and”.

Re: Sorting by item ... of each and item ... of each

[Craig Newman via use-livecode]

I should have given better context. I one only sorts the same field numeric, 
one gets:

123

132

213

231

312

321

Which is correct given the list of whole numbers in question. The stable sort 
allows one to then sort by char 3 of each, to get the result in the “compound” 
sort below.

So am I missing something in all this?

Re: Sorting by item ... of each and item ... of each

[Craig Newman via use-livecode]

I may be simply misunderstanding…

Since HC days, one could concatenate sort criteria using the “&” character, and 
obtain multiple stable sorts in one go. In LC as well, since given, in a field 
1:

231

312

123

213

321

132

and in a button somewhere:

on mouseUp

get fld 1

sort it numeric by char 1 of each & char 3 of each

answer it

end mouseUp

We get:

132

123

231

213

321

312

Re: Merging PDF pages

[Craig Newman via use-livecode]

Hmmm.

Rereading, did you want to be able to collect existing pdf documents, read 
them, and then output a single new PDF?   If so, I guess you can import those 
documents as images on successive cards, and do what I posted earlier.

Seems clunky, but then you are asking LC to do something clunky.

Re: Merging PDF pages

[Craig Newman via use-livecode]

Hi.

Sure. Try this in a button on card 1 of a new stack with, say, three cards:

on mouseUp

get the desktop folder

open printing to pdf it & "/" & “yourNamehere" & ".pdf"

repeat with x = 1 to 3

print card x

end repeat

close printing

end mouseUp



And I wonder if the new pdf widget has that built in.

Re: Variable Watcher disappeared

[Craig Newman via use-livecode]

What happens if you set the top of the SE window a bit higher than current?

I have a gadget that locates the SE on my portrait monitor on command. I could 
easily make its top anything I want, and I bet that would display the hidden 
bottom of the window.

Re: Reorder fields

[Craig Newman via use-livecode]

Why does, as Paul suggests, changing the layer order in the Project Browser 
work, whereas changing the layer order explicitly does not? We know that layers 
cannot be assigned to a particular object class (like fields) but include all 
controls at once. Is it possible that the layer order of the fields only was 
not properly grokked?

I was sloppy, as usual. Trap the message in the card, and use the target to

Re: Reorder fields

Hi.

Not sure why the tabbing order seems to be out of whack, but you can always 
force the issue by trapping the tabKey message in each field, and directing it 
to the next one of you own choice.

Re: Determine the screen DPI

[Craig Newman via use-livecode]

Hi.

The “screenrect” gives you the factor required directly. If you measure the 
actual width, say, of the screen and divide that into the difference between 
item 3 and item 1 of the screenRect, you will get the number of pixels per inch.

Re: What is your best practice for setting a script in a script?

[Craig Newman via use-livecode]

Paul.

I assume you have a blueprint of what will become a stack with at least one 
card? And that stack will possibly contain other cards, controls, scripts and 
behaviors?

But since all objects have properties, including scripts, and since LC has the 
“create” command, whatever you want to do seems straightforward, if not simple.

You must have the IDE open to even start, of course, so you are already “in” 
LC. Why not just do it the old fashioned way? The end result will be a stack, 
correct? What is the advantage of not starting with a stack?

Re: Field highlited

[Craig Newman via use-livecode]

Paul.

I think that Bob S. is correct. The change in focus is sort of built into the 
engine, and a field cannot “remember” such a thing.

A fun kludge would be to create one or more overlays, however you like those to 
look, and apply them to the field of interest. These overlays can be managed in 
terms of their rects, depending on the formatted properties of the hilted line 
or lines. They can be shown and hidden as well.

I am struggling not to do this just for fun. So you do it, because I bet that 
the team has bigger fish to fry.

Re: Answer dialog text missing in standalone 9.6.9

[Craig Newman via use-livecode]

Matthias makes a point. Sometimes trying with a brand new stack will show that 
there is something amiss, even corrupted, with the stack of interest. If the 
new stack works, it likely means that LiveCode works, and the problem lies 
within the recalcitrant stack.

Hi.

I assume you mean the standard “Answer” command. There is no “Answer Text”.

So if you:

answer “Some Text" with “Yes" or “No"
what exactly pops up?

Re: Can Xavvi generate sensible text output as well as code?

[Craig Newman via use-livecode]

In Jacque’s “test” AI first had to create a list of ten “people”, garnered, I 
assume, from research into our planet’s knowledge base. It knew what a “name” 
should be. That is cool.

That list could have been a list of actual humans, derived from, say, the staff 
of a particular bank. 

If the list alone was in hand, it would take just a handful of LC code to 
create the string associated with each name.

How to integrate the AI part with the LC part? Again, one could acquire just 
the list, and then let LC generate the output string. But at least all would 
end up in a handler, fully in LC, where I assume additional “real” work would 
then be done.

What I mean is, how can one best integrate the “outside” AI work with the 
“inside” LC work? That is what I have to get my head around.

 Lurking in the background,I do not want AI to put LC out to pasture. I did 
that once with HC, and still have not gotten over it.

Re: Am I using the best mail client?

[Craig Newman via use-livecode]

Thank you all.

I will stick with the Mac client.

The reason I like the forums better is what I see as a far more helpful UI. We 
all know how it works.

Enough said of this.

Since I got real help here, and not on the forum(hmph), I am wondering if the 
eMail client I am using is one reason I do not prefer this venue.

I am using the native Mac “Mail’ client. Are there much better ones?

Heather.

THANK YOU. That worked.

Not that I care much, but was it Ventura or the new machine itself that 
required re-licensing? 

Ralph.

Thanks to you as well.

Cannot make a standalone after upgrading to Mac Mini and Ventura

[Craig Newman via use-livecode]

All.
Help
I got a new Mac Mini a month ago. Lovely. Working with LC on it. Lovely.

I tried to make a windows standalone from the same project I have for years. In 
the Applications Settings I cannot select the Windows pane. It is essentially 
disabled, and looks like it.

In fact, I cannot select any pane except the Mac one. The Mac standalone 
proceeds as usual, but there is nothing done on the Windows side.

I made a brand new stack. Same issue; only the Mac pane is accessible.

Before I put the splash stack and the mainStack on a thumb drive and reload 
them back on my old iMac to make an updated standalone, is it me or Ventura?

Re: opencard and visual effect

[Craig Newman via use-livecode]

I never use visual effects, though I played with them a lot in about 1988. They 
are “blocking” in some sense, so I think you are beat served by losing them 
entirely in your planning.

Re: opencard and visual effect

[Craig Newman via use-livecode]

Klaus.

That was fun.

Oh yes, the point of this thread.  To me it seems that preOpenCard is sent 
before, and openCard is sent after the effect terminates. The fact that you 
have 0 and 3 ticks is no different than having 0 and 125 ticks, The speed of 
the visual effect is not pertinent.

Well, except for the speed of the visual effect. -;)

Note pitiful “wink” emoji above.

Re: opencard and visual effect

[Craig Newman via use-livecode]

Klaus.

It is a works-much-better thing. Script samples and quotes can be separated 
from the main body of text. One can attach stacks and, for Richmond at least, 
silly photos and art layouts. One can edit past posts, or even delete them.

One can search threads in many ways.  MANY.

I was going to attach an emoji, but, well, we are in the use-list.

Otherwise, nothing significant.

Jacque.

Go to the forum. I did just that, and the “openCard” message appears in the 
message watcher exactly after the visual effect finishes.

Come back from the dark side. If you do I will send you the stack I made that

Re: opencard and visual effect

[Craig Newman via use-livecode]

Klaus.

Why aren’t you doing this in the forum???

I made a stack with two cards. Card 1 has a button on it:

global tTime

on mouseUp

put the ticks into tTime

visual effect "checkerBoard" slow

go cd 2

end mouseUp



In the card 2 script:

global tTime

on openCard

put the ticks - tTime into fld 2

end openCard



I get about 60 ticks, so it seems the message is sent AFTER the visual effect 
completes. Know that with “preOpenCard” I get 0 ticks; the message is sent 
before the visual effect.

Re: opencard and visual effect

Klaus.

I would guess that as soon as the card was navigated to, that is, before any 
visual effect starts or finishes.

Not sure how to test this since I am not sure what messages or properties might 
be set before, during or after a visual effect runs.

Re: How to loop through stacks with same name?

[Craig Newman via use-livecode]

Bi.

There has been much discussion on the forum why, if the “destroyStack” property 
is set to “true”, there still seems to be remnants of that stack that linger 
when the “close stack” command is given.

Nonetheless, have you established that this property is set? If not, set it, 
and let us know if that worked.

Re: Is it possible to use a reverse direction for offset

[Craig Newman via use-livecode]

Fun, fun…

So if you collect ALL the opening and closing strings, and hopefully these 
never overlap, then each pair can be “ordered”. Now identifying each is just a 
matter of thinking in terms of “pairs” of offsets. You can then identify each 
by their “paired” position in the forward direction.

Or am i missing it still?

Re: Is it possible to use a reverse direction for offset

[Craig Newman via use-livecode]

Francois.

I am sure you know what you have and what you need.

But just for my curiosity, if I had to do what you want, I would have used the 
“offset” function and its “charsToSkip” parameter to find all instances of the 
text to find, and then use those values in sequence to work backwards. But then 
how do you know when to stop?

Re: Chat and textarea formatting

[Craig Newman via use-livecode]

Hi.

Not sure I understand.

You have an editable field that you cannot type into? Do you get a blinking 
cursor in that field if you click inside it?

Perhaps some properties for that field are such that LC is preventing access?

The stack I made to test this became corrupted after a couple of runs. I guess 
the way to do this is to increase the length until a crash, not decrease.

But I assume that there is a value where a field can be loaded and display a

Re: Maximum field size

David.

You want to display 1.39 GB in a field? Will it scroll?

I made a quick test stack that created a variable with a length of 1.4 GB. No 
problem.

But when I tried to put that variable into a field, LC crashed. When I tried to 
put 140 MB into a field, same crash. I did not continue to reduce the length of 
that variable until the field could be loaded.

I will bet that you have to get the points, write a short routine to reverse

Somehow that last was mixed up with the concept of any number being able to be

Re: ChatGPT

[Craig Newman via use-livecode]

As Mark said…

So if you have, say, 22, which is divisible by the prime “11”, then it is also 
divisible by 7""???

Re: Lock screen and animated gif

[Craig Newman via use-livecode]

Jbv.

"Every ten lines"???

Is your handler using a loop to massage each of those lines? If so update the 
scrollbar every 10 passes through.

So if you are using “repeat with…” you can do something like:

repeat with y = 1 to whatever
  if y mod 10 = 0 then updateYourThingie

And if you are using “repeat for” then you must add your own counter:

repeat for each line tLine in yourText
add 1 to counter
if counter mod 10 = 0 then updateYourThingie

Re: Lock screen challenge

[Craig Newman via use-livecode]

Jacque.

Why aren’t you on the forum?

Cant you just loop through each line in your handlers, and find the ones that 
contain “lock screen”, both with and without the visual effect thing. Search 
downstream until you find the “unlock” line, That gives you the start and 
finish lines for each handler. Then you can just replace the start and finish 
lines with the new ones.

Am I missing this?

Re: Return of Hilited text of Popup Menu items

[Craig Newman via use-livecode]

Roger.

No messages are sent while a menu is open. Further, a “mouseMove” handler in, 
say, the card script stops receiving messages while that menu is open.

Such a gadget, likely drawn by the underlying OS, seems to be blocking. So, I 
think, no.

Odd we have so many different actions. I am on a Mac, with an Apple keyboard. 
Enter works as advertised. I have a MacAlly keyboard, and Enter works there as

Re: ENTER in scripts

All.

"Enter" has always worked for me. And focus has always been required to be in 
the SE for it to do so.

This seems logical to me. It would not do for actions specific to certain 
spaces to be affected, or effected, when not in that space.

Re: Control or right click to show popup menu

[Craig Newman via use-livecode]

Hi.

On a new card make a field and a pulldown menu button. Place a few lines of 
text in the field and lock it. In the field script:
on mouseUp

set the loc of btn 1 to the mouseloc

click at the mouseLoc

end mouseUp

The menu opens at the line clicked on. 

This has been discussed extensively in the forums, if you want to search there. 
That discussion mainly dealt with loading the contents of the button with the 
field contents, or the selection of a particular menuItem once the menu itself 
was open.

Re: Weird performance issue

[Craig Newman via use-livecode]

Something weird happened to my post.

I modified your handler to access only those stacks that appear when calling 
the function “the stacks”. In all those cases, the return time was only a few 
tenths of a second.

But “revNaviigator” does not appear on that list. So there must be a longer 
pathway for LC to find a stack that certainly must be in memory, but that does 
not appear in the “stacks” list?

Re: Shouldn't space or enter in a menu select the hilited item?

[Craig Newman via use-livecode]

Yes, the combo box does not return the “selected” menuItem. Likely something to 
do with its compound nature.

Re: Shouldn't space or enter in a menu select the hilited item?

[Craig Newman via use-livecode]

Hi, I was not complete. Once the arrow keys have found the menuItem of 
interest, clicking Enter or Return executes the menuPick handler.

Re: Shouldn't space or enter in a menu select the hilited item?

[Craig Newman via use-livecode]

Hi.

I am missing something. Make a popup menu button. Ina mouseUp handler in 
another button:

on mouseUp
  click at the loc of btn 1
end mouseUp

Once the menu is open, the up and down arrow keys navigate among the menuItems.
