You can check the "owner" of the button and see if it is a shared group 
or not.


You can get a list of the shared groups that are being used on a card by 
using "get the sharedGroupNames of card xxx".


For buttons that aren't in groups, the owner will be the card.  If they 
are in a group, the owner of the button will be the group they are in.


Cheers,

Target controls on a card that are *not* part of a placed groups

[Sannyasin Brahmanathaswami]

 
I'm trying to customize some development tools. A typical use case it to be 
able to change the button style of all the buttons on a card, but I don't want 
to touch the style of buttons that are part of top and bottom nav bars that are 
placed on all cards.  I need to be able to go into a review process and if 
someone says "Let's see what it looks like if we change the buttons to look 
like XYZ"

I have this in a field of a tools stack:

backgroundcolor|65,65,65
ink|blendHardLight

and a button with this script

on mouseUp

put fld "buttonProps" into tButtonProps
split tButtonProps with cr and "|"
set the defaultStack to the topstack
repeat with x = 1 to (the number of buttons of this card)
# what I really want to do here is skip all the buttons that are in groups
# which are placed on all card (or more than one card
   repeat for each key y in tButtonProps
     set the y of btn x of this card to tButtonProps[y]
   end repeat
end repeat

end mouseUp

If you have a better way to tackle this.. it's something I've worked with for 
years and never came up with an easy solution. 

I also like the idea of selecting the buttons... then I can use this

on mouseUp

   put fld "buttonProps" into tButtonProps
   split tButtonProps with cr and "|"
   set the defaultStack to the topstack
   put the number of lines of (the selectedObjects) into tObjects
   if tObjects = 0 then 
      answer "Please select some controls" with "OK"
      exit to top
   end if
   
   repeat for each line x in (the selectedObjects)
      repeat for each key y in tButtonProps
         set the y of x to tButtonProps[y]
      end repeat
   end repeat
   
end mouseUp

Anyone have an even more efficient method? How do you handle this?

You added the following 5 requirements after my response containing the 
suggested implementation:

1. The PDF file itself is also to be encrypted with a password.

2. The PDF encryption is not to be performed beforehand using Acrobat.

3. The PDF encryption is to be performed on the server.

4. The PDF file is to remain encrypted upon receipt.

5. The user is to be prompted to enter the password to unlock it.


With your above additional requirements in mind, the suggested implementation 
would be as follows:

- Store the PDF on the server, somewhere outside the web folder so it can’t be 
loaded directly by web visitors.

- Get the user to access the system via a HTTPS connection, which is needed for 
a secure login mechanism anyway.

- The HTTPS connection does all of the encrypting and decrypting so you don’t 
have to code it yourself.

- The user logs in via your LiveCode Server app, which handles the usual user 
authentication stuff using cookies and sessions.

- When the logged in user asks for the PDF file, have your LiveCode Server app 
generate a new password and send it to a command line app that has the ability 
to encrypt PDF files, such as PDFtk:

https://www.pdflabs.com/docs/pdftk-man-page/

- Have that command line app output the encrypted PDF file to a location 
outside the web folder so it can’t be loaded directly by web visitors.

- Have your LiveCode Server app display the newly-generated password on a page 
in the web browser, with an accompanying download link which calls your 
LiveCode Server app.

- When the user clicks the download link, have your LiveCode Server app read 
from the encrypted PDF file and write it out to the web browser (as with any 
other web content), and with the appropriate Content-Type HTTP header.

- Since you’re having all data transmitted over a HTTPS connection, the user’s 
login details as well as the PDF file are encrypted whilst in transit.

- Since your LiveCode Server app is the one deciding whether or not to display 
the PDF (and any other data) based on whether the user is signed in, access can 
be effectively limited to that user.

Sorry, I cleaned out my mailboxes earlier. Look for Lyn's longer reply

Re: Release 6.7.10 RC 1 / 7.1.3 RC 1

[Robert Mann]

Added to that,  it is a very nice and very respectful attention of the
livecode team to maintain these last builds that are still governed by the
perpetual licenses that existed in the previous century. 
(sigh.. mine stopped at 6.6.5 sniff!)

Re: Release 6.7.10 RC 1 / 7.1.3 RC 1

[Richard Gaskin]

Good work - results more or less confirmed here.

Might be good to submit that script with an enhancement request in the 
bug DB to see if those use cases can be optimized.  Previous requests 
with other commands and functions yielded good opportunities for speed 
boosts, bringing v8 much closer to v6.  Whether the same can be done 
with the language features used here is something I don't know, but once 
in the queue the team can review and advise.

Let's take a simple example that was recently here in the list.
For your comfort the script is attached below.

It is also a field, where LC 8 is said to be already optimized.
Correct me if I'm wrong.

Here are my results from a medium fast machine (Mac mini, i5-2.5GHz)
Task (=1 x mouseUp): 100 repeats of find the minimum of 1000 integers

Version: replaceText - replace - min() - sort
6.7.10-rc1: 0.30 - 0.07 - 0.06 - 0.21 (worst timing of 10 x mouseUp)
7.1.3 -rc1: 1.78 - 4.43 - 1.38 - 0.95 (best  timing of 10 x mouseUp)
8.0.0-dp15: 1.94 - 4.69 - 1.49 - 0.94 (best  timing of 10 x mouseUp)

So the time needed is in relation
for the "LC-given" min()
... LC 6: LC 7: LC 8 = 1:23:25
and better for the sort
... LC 6: LC 7: LC 8 = 1:5:5
taking the best of each row
... LC 6: LC 7: LC 8 = 1:16:16

Better don't force me to publish the results of animating large polygons.
*** I left these timings out in averaging in order to acknowledge that
*** LC 8 is still in alpha.

I like LC 8 very much and I live with the speed loss I have when I use it
(it's worth for me, if I do so). The speed loss is not the culprit of the
dev team, it's the big bundle of shiny new things we wish to have ...

The script used
(by Thierry, slightly modified and expanded by me)

on mouseUp
  repeat with i=1 to 1000
get random( 1000)
put IT & cr after LinesOfNumbers
put IT & comma after OneLineOfNumbers
put IT into b[i]
  end repeat
  delete last char of LinesOfNumbers
  delete last char of OneLineOfNumbers
  put 100 into nRepeat
  put the milliseconds into _ct
  -- case 1
  repeat nRepeat
put min( replaceText( LinesOfNumbers, return,comma)) into min1
  end repeat
  put (the milliseconds - _ct)  / nRepeat into timing1
  wait 1 ticks with messages
  put the milliseconds into _ct
  -- case 2
  repeat nRepeat
put LinesOfNumbers into nn
replace return with comma in nn
put min(nn) into min2
  end repeat
  put (the milliseconds - _ct)  / nRepeat into timing2
  wait 1 ticks with messages

Re: Use MouseLine() and still edit the same field?

Mark,
I had a situation where it thought I was French. Go to your setups or 
preferences and look at language settings. I also find that asking Google for 
info is useful, even for questions about livecode.

Set htmlText in LC8 Browser

[Terence Heaford]

There seems to be an issue with set htmlText in LC8 Browser.

The code below generates a chart using amCharts.

It works in Safari with either Open File… or drag and drop.

It works in a LC8 Browser by drag and drop

It DOES NOT work in LC8 Browser by set html text.

Can someone advise please?


Thanks

Re: Use MouseLine() and still edit the same field?

[Mark Mitchell]

Thanks to Devin, Terry and Matt

I tweaked Devin’s code a bit, and went with a global variable as otherwise it 
flashes and gives you an epileptic seizure!

But, this works great:
on mouseWithin — seems to work better than mousemove
 global PastWhichLine
   
   if pastWhichLine is empty then
  put the mouseLine into pastwhichLine
   end if
   
 put the mouseline into tThisLine
if tThisLine <> PastWhichLine then

   set the backgroundColor of pastwhichline to empty
   set the backgroundColor of tThisLine to (220,220,250)
   put tThisLine into PastWhichLine
   end if
end mouseWithin

Thanks folks!

there is no way to stop it… sigh…)

Re: Activating tabs in a liveCode field

[BNig]

Hi Francis,

if you convert the word document to a RTF document then you could drop it
onto a field from the finder.

The field would have this script

-
on dragDrop
   put the dragData["files"] into tFiles
   put line 1 of tFiles into tAFile 
   set the itemDelimiter to "."
   if item - 1 of tAFile is "rtf" then
  put url ("binfile:" & tAFile) into tRTF
  set the rtftext of me to tRTF
   end if
end dragDrop


it even respects the tab positioning.
Tested with a simple 2 line 3 columns text, for more complex documents it
might differ.

Note as of LC8 DP8 onwards the field object does not accept dragDrop from
the Finder on MacOSX. Bug 17072

Kind regards
Bernd

Activating tabs in a liveCode field

Hi from Beautiful Brittany,

I have a Word file containing tab characters.
I want to drop it into a liveCode field, and have
the tabs respected (all texts lined up)

Can I do this ?

Thanks for any ideas.
