I couldn't get this to work until I altered it, but I was using a very 
simple array. What type of array data did you use? I think I'm missing 
something.


I just did this:

  put the weekdayNames into tDataA
  split tDataA by cr
  simpleSortNumberedArray tDataA, "descending,text"

What you're missing is that this (simpleSortNumberedArray) is only 
intended for "numbered array"s (which LC is calling "sequences" in some 
places); i.e. an array where the (top-level) keys are all consecutive 
integers, from 1  n


Also, the pSortkeys should be a number of comma-separated items, each of 
which consists of a key by which you want to sort the array followed 
optionally by an order and type.


So you might do something like :


on mouseup
   local tCounter, tDataA

   repeat for each line L in the weekdayNames
  add 1 to tCounter
  put L into tDataA[tCounter]["dayname"]
  put the number of chars in L into tDataA[tCounter]["charcount"]
   end repeat

   -- sorts ascending by name (i.e. F, M, Sa, Su, Th, Tu, W)
   simpleSortNumberedArray tDataA, "dayname"
   repeat with I = 1 to 7
  put tDataA[I]["charcount"] && tDataA[I]["dayname"] & CR after msg
   end repeat

   put "-" &CR after msg

   -- sorts descending numeric by number of characters in name
   --  NB within each char count value, they remain in alphabetical 
order of name

   simpleSortNumberedArray tDataA, "charcount numeric descending"
   repeat with I = 1 to 7
  put tDataA[I]["charcount"] && tDataA[I]["dayname"] & CR after msg
   end repeat
end mouseup

and get as output


6 Friday
6 Monday
8 Saturday
6 Sunday
8 Thursday
7 Tuesday
9 Wednesday
-
9 Wednesday
8 Saturday
8 Thursday
7 Tuesday
6 Friday
6 Monday
6 Sunday


So - it would be worth adding a check that the array passed in is indeed 
a sequence, at the start of simpleSortNumberedArray:


if NOT (pArrayDataA is an array AND \
   item 2 of extents(pArrayDataA) is the number of elements in 
pArrayDataA) then \

 return pArrayData

I'm now going to add this to my personal library, but I'll rename it to

    seqSortMultipleKeys

Alex.

I just did this:

For that array, this worked:

  local tKeys, tSeq, tOneSortKey, tSortCommand
  put seqAsLines(pArrayDataA) into tKeys
  repeat with I = the number of items in pSortKeys down to 1

--put "sort lines of tKeys" && word 2 to -1 of tOneSortKey && \
--  "by pArrayDataA[each][" && word 1 of tOneSortKey && "]" into 
tSortCommand
put "sort lines of tKeys" && tOneSortKey into tSortCommand
do tSortCommand
  end repeat
  rebuildSeq pArrayDataA, tKeys
end simpleSortNumberedArray

function seqAsLines pSeq
  local tRes
  --  repeat with i = 1 to the number of elements in pSeq
  repeat for each element e in pSeq
put e & CR after tRes

That's called an ANR ("Application Not Responding"). Something in the app is causing a hang. If 
you wait long enough, Android should put up a dialog asking if you want to wait or close the 
app. If you choose to wait, sometimes it comes back. However, the wait can be 10-20 seconds or 
more so people often just quit before the dialog appears.


The problem here is figuring out what causes it. Is it always the same PDF file? Or maybe it 
happens after opening a certain number of files, or the length of a file, or the cumulative 
length of several files, or...? If it isn't reproducible, it's very difficult to find the cause.


If it happens to you at home some day, see if waiting 15 seconds or more puts up that dialog. 
That would confirm it's an ANR.

Tab Widget Go command

2023-08-11 Thread Bob Sneidar via use-livecode

In the dictionary, there is a Go command for widgets. I assumed this meant I 
can do something like: 

Go forward in widget “TabBar”

But that does not work. Any ideas? I can kludge it. I would rather not have to.

Re: Rectangles on Windows?

If you want to send me a link to your Windows standalone, I would be 
happy to download it (Windows 11 HP laptop) and see if I see the same 
thing. Or a link to your stack and I can see if it appears in the LC 
9.6.9 IDE if you want.

Two sets of rectangles are not visible in Windows. One set is opaque and one

Both sets have a non-zero border thickness

Showing Up
Other rectangles have opaque true, backgroundColor red, and border thickness 0. 
They are visible on Windows. They are also within a group. These are made

sorry, my fault, I obviously have an older version of the tablet and it does in 
fact run Android 8.1.
However it is not upgradable.

I already did that, snice I only need the device for displaying PDF leadsheets.
But if it would be a memory issue, then it would happen more often, I think.

The problem is that this is not reproducable, it happens out of a sudden if it 
happens.
Even the hardware BACKKEY does not work in that situation, only the HOMEKEY so 
I can 
at least quit the app.
