PLEASE, feel free to pull the thing to bits.

I don't want to "pull the thing to bits". Like you, I enjoy seeing 
"competing" multitude of ways to do things - I can learn from them all.


But I did have a quick look, so I'll just point out a small number 
of nitpicks.


1. the whole 'locktext' thing is weird, and causes various anomalies.
When I first open the stack, and click in the field, I can type 
digits and have them appear in the field, as you'd expect. But once 
I've clicked on an 'arrow-emulator' the field becomes locked and one 
can no longer type in characters. Clicking *outside* the field will 
then free it up again, so typing becomes possible.


2. disappearing iBeam.

If I position the ibeam in the middle of the text in the field, and 
use one of the arrow emulator buttons, the iBeam moves properly - 
but then disappears (perhaps when the 'locktext' is set true).


3. incorrect entry position.

As in 2 above, although the ibeam was last seen in the correct place 
after using the ">" button to move it to the right, if I then click 
on a digit button, that digit appears at the end of the field, not 
where it should have gone


4. Incorrect arrow key emulation (same problem as I mentioned in the 
previous email).


If you select a chunk of text in the field, then use the left-arrow 
emulator button, the ibeam is positioned before the *last* character 
of the selection, instead of before the first.



There were a couple of others, omitted for brevity. I've created a 
modified version your stack with my suggested handlers, and will 
attempt to upload it to the forum later.


Then there was another issue which I haven't tackled - it would mean 
changing lots of very similar tiny scripts, and is too tedious.


5. character input should replace any selection

Just like in a regular field, if there is an active selection, 
typing a character (or clicking a digit button, should *replace* it, 
not simply add the newly typed (or clicked) digit.



I've taken my earlier handler suggestion, and broken the bits of 
code out into individual button scripts, which removes the apparent 
complexity that you disliked earlier. As far as I know, no problems 
have yet been found with that approach. As one example, the code for 
left-arrow emulator would be



  on mouseUp
    focus on field "fWORK"
    put word 2 of the selectedchunk into tFirst
    put word 4 of the selectedchunk into tLast
    select before char (min(tFirst, tLast)) of fld "fWORK"
end mouseUp

I've uploaded this revised version on the forum thread.

I did not mean "competing" in the sense of "b*gger you", I meant it in the
sense of healthy competition.

"But having said that:  your "left-arrow' emulation gets it wrong if 
there is a chunk selection active."


Quite possible as I spent about 15 minutes on that yesterday between 
raking up dead leaves,
drilling through the metal head of a broken rake to screw it onto a 
wooden handle, and a whole
slew of other things such as talking to my son in Lilongwe re setting up 
discarded PCs out
there (Malawi) with Xubuntu and a programming suite that has recently 
been effectively abandoned.


I have a sackload of kids writing that has just arrived via Viber that 
has to be addressed:
after which I'll have a look at my "half cock job" and see if I can 
tweak it.

no, that is the RAWKEY code for that erm. key. :-)
Use it in a "rawkeydown/up" handler.

Here it is again, below.

Or download the sample stack at 
https://tweedly.org/downloads/calcbuttons.livecode


 - not as pretty as Richmond's, doesn't even have all the digits ...)

Previously I said:

Here's an expanded snippet. The input is in a field called "fInput", the 
buttons are all in a group, and handled by the group script (saves 
having many tiny almost identical scripts).


The script  uses the name of the target - but since I would never, ever 
have a control named as a number, the digit buttons use their label 
instead.


If the user cannot select a chunk of text then some of this could be 
shortened.




on mouseup
   if the target = me then
  -- click in the background in the group
  exit mouseup
   end if
   local tChunk
   focus on fld "fInput"
   put the selectedchunk into tChunk
   if the label of the target is a number then
  put the label of the target into the selectedchunk
  exit mouseUp
   end if
   local tFirst, tLast
   put word 2 of tChunk into tFirst
   put word 4 of tChunk into tLast
   switch the short name of the target
  case "go left"
 select before char (min(tFirst, tLast)) of fld "fInput"
 break

 break

 -- remove the selection, or the char *after* the ibeam
 if tFirst <= tLast then
    put empty into char tFirst to tLast of fld "fInput"
 else

 end if
 break

 -- remove the selection, or the char *before* the ibeam

 else

Re: Control of Text Fields.

2021-11-05 Thread Alex Tweedly via use-livecode

Hi Roger. Don't know if you've seen the script I posted around 6 hour 
ago ("expanded snippet").


It does the correct forward / backward key movements, and also 
implements both "backspace" (delete the char to the left of the iBeam) 
and "delete" (remove the char to the right of the ibeam) as well as 
properly handling the case where there is a text selection rather than 
just an ibeam (i.e. both delete the selection, but not any characters 
outside that selection).


Alex..

Why do you need to emulate them?

Will you NOT have access to a physical keyboard?

Here's the script of a stupid button to DELETE one number in
a calculator read-out:

I am sorry for that misunderstanding: I had a fairly fixed idea of what
constituted a calculator in my head, and what you seem to want with your 
back, forward and delete keys seems more

"word-processory".

Re: Control of Text Fields.

2021-11-05 Thread Alex Tweedly via use-livecode


OK, so I was close, but didn't get the cigar.

Here's an expanded snippet. The input is in a field called "fInput", the 
buttons are all in a group, and handled by the group script (saves 
having many tiny almost identical scripts).


The script  uses the name of the target - but since I would never, ever 
have a control named as a number, the digit buttons use their label instead.


If the user cannot select a chunk of text then some of this could be 
shortened.




on mouseup
   if the target = me then
  -- click in the background in the group
  exit mouseup
   end if
   local tChunk
   focus on fld "fInput"
   put the selectedchunk into tChunk
   if the label of the target is a number then
  put the label of the target into the selectedchunk
  exit mouseUp
   end if
   local tFirst, tLast
   put word 2 of tChunk into tFirst
   put word 4 of tChunk into tLast
   switch the short name of the target
  case "go left"
 select before char (min(tFirst, tLast)) of fld "fInput"
 break
  case  "go right"
 select after char (max(tFirst, tLast)) of fld "fInput"
 break
  case "Del"
 -- remove the selection, or the char *after* the ibeam
 if tFirst <= tLast then
    put empty into char tFirst to tLast of fld "fInput"
 else
    put empty into char (tFirst) of fld "fInput"
 end if
 break
  case "BS"
 -- remove the selection, or the char *before* the ibeam
 if tFirst <= tLast then
    put empty into char tFirst to tLast of fld "fInput"
 else
    put empty into char (tFirst-1) of fld "fInput"
 end if
 break
 -- all the other keys !!
  default
   end switch
end mouseup

Hi Roger,

I'm not sure I properly understand your question.

here's a code snippet the moves the insertion point (in this sample, 
typing an 'f' moves it forward, 'b' moves it back). (Note this also 
works if there is some text selected - it moves the insertion to just 
after the selection, just like the arrow key does).



on keydown p
   local t

 put word 4 of the selectedchunk into t
 select after char (t+1) of me
 break
  case "b"
 put word 2 of the selectedchunk into t
 select before char (t-1) of me
 break
   end  switch
end keydown

To then delete the char in front of it, you'd do something like

   put empty into char (t+1) of me

Hope that's close enough to what you were asking, or at least gives you

Possibly memory corruption, but unlikely.  More likely a plugin or IDE 
element with test code hanging around.


If only there was a way to trace message handlers so you could see where 
the culprit lies...

Control of Text Fields.

2021-11-04 Thread Roger Guay via use-livecode

I simply want to be able to move the insertion iBeam in a focused field left 
and right, one char at a time (just like the left and right arrows keys), and 
then to delete the char in front of it (just like the Delete key). The 
dictionary was again of no use to me. Can someone please provide sample scripts?

Thanks,
Roger
