Thank you, Mark. Bookmarked.

LiveCode makes it so easy to take things like text editing for granted.

"Just drop a field onto a card and start typing - what could be so hard?"

And then we read what it takes to make that happen...

Which returns us to the question I posted an hour ago about the Roadmap:

   What purpose does it serve?

I can imagine all sorts of reasons one might find a roadmap useful. 
Some may find it useful for planning features down the road for one's 
own products (provided, of course, a solid understanding of what a 
roadmap is, and isn't, is in place); others may find it useful for 
anticipating areas of future contributions to the project (new widget 
opportunities, etc.); others may just find it interesting to see how the 
company envisions growth opportunities as reflected in feature sets.


There are all sorts of really good reasons people might want a roadmap.

And then there's yours:

  "...to hold LC to account..."

If that's your interest, I see no benefit in keeping the Roadmap.

That is great, I can even use an insanely high number to scroll to the bottom
without knowing the exact "formattedheigt" of the widget, just like with LC

I used BBEdit with encoding set to UTF-8 for the "skeletal structure"

Re: encoding woes!?

[hh via use-livecode]

Hi Klaus,

this is dangerous because the code could have "mixed" encodings
if you (or your partner) edits the code in texteditors with
different encoding settings.

I looked again carefully into your first post.
You use the htmltext of the widget, so your original code is correct.
It works here as you would like.

So delete the file test.html and write it new by LC using 
put textencode(the htmltext of widget "browser","UTF8") \
  into url("file:" & specialfolderpath("desktop") & "/test.html")
  
Possibly there was some problem when you self-created the file.
I set the default encoding in BBEdit to UTF-8.

Also LiveCode uses a BOM. If there is no UTF-8 BOM it uses
Mac OS Roman. That is what you see when you type into msg
put textEncode(the htmltext of widget "Browser", "UTF-8").

If you use later on text from the DOM structure of your HTML,
have to decode before using in LC/writing to a file.
handlers.

I use this always together with base64Encoding (because javascript
handlers need ONE line of code in quotes).

Hi all,

I don't really understand this, but this finally does the job:
...
put "" after tText
## NO encoding before setting the htmltext!?
set the htmltext of widget "source" to tText

put textencode(tText,"UTF-8") into tNewText
put tNewText into url("file:" & Kommunikations_ordner() & "kommunikation.html")
...
Now loading that file again into the widget looks as exspected, ph! :-)

Re: encoding woes!?

[hh via use-livecode]

Just saw it now, overlooked that first:

You script
put textencode(tTExt,"UTF8") into url ("file": ...)

This should read
put textDecode(tTExt,"UTF8") into url ("file": ...)

=

But why using files?
If you don't want to type directly in the browser widget
you can make it "mirroring" a text field.

Example for a primitve HTML editor:

1. Write into fld "HTML"

[[ht]]
(You can now hide fld "HTML").

2. Then make a field "Tippse" and script it:

on textchanged
  put the htmltext of me into ht
  replace "" with "" in ht
  replace "" with empty in ht
  set htmltext of widget "browser" to merge(fld "HTML")
end textchanged

on enterInField
  textchanged
end enterInField

Then you can do what your textfield allows
set textfont (bears some problems), textsize, styles etc.
and the widget will display it (well, approximately...)

[Another variant is to write directly into the DOM structure
of the current HTMLtext.]

Re: identifying text chars in an image

[Phil Davis via use-livecode]

Thanks for your great ideas Hermann. In my next experiment I think I'll 
start by looking for any scrabble tile by looking for its [known] 
background color, and then work out to its edges. That should give me 
both the grid cell size and a starting point for discovering all cells 
in the grid.


Unless anyone knows of something simpler?

You need some criteria to find the topleft of the grid and the
size of one letter: color/transparency/a marker(fixed image part)...
You could also use pattern recognition for that.

Then it's the easy part to get all possible letters by computing the
grid and crop (get from imageData) the grid elements by script.
Then doing the OCR for each single char.

If you need that for a standalone, then 'tesseract' with its huge
language packs is probably not appropriate and 'ocrad' could be
good enough for that.

Re: drag'n'drop in text fields

In those cases the selection change is a side effect of something else.  The 
user isn’t changing the selection, the user is doing something else that 
changes the selection.  As this thread covered, the textchanged message is sent.

I think it fully makes sense to only send one of those two messages.  Otherwise 
just about every key press inside a field would generate 2 messages.

encoding woes!?

[Klaus major-k via use-livecode]

Hi all,

macOS 10.14.6, LC 9.5

I have a file created with BBEdit with this content:
--


-


äÄüÜöÖßßß

---
Then I set the url of a browser widget to that file.
All fine so far...

Now I want to add some more text with umlauts to that file:
...
put the htmltext of widget "browser" into tText
## Looks exactly like the above in the debugger!

put "ööääüü" & CR before line -1 of tText
## Last line is the footer -> 
## And when I set the HTMLtext of widget "browser" to tText, all is fine, too
set the htmltext of widget "browser" to tText

## Then I do:
put textencode(tTExt,"UTF8") into url("file:" & specialfolderpath("desktop") & 
"/test.html")
...

When I now load that file into the widget:
...
set the url of widget "browser" to (specialfolderpath("desktop") & "/test.html")
...
Umlauts are gone like -> äÄüÜöÖßßß or worse

If I paste the same content (of tText copied from LC) in BBEdit and save the 
file it looks great
in the browser widget and Safari.

What am I missing or doing wrong?
Clueless... :-/

Thanks a lot in advance!


Best

Klaus

pdf conversion

[Mark Wieder via use-livecode]

I just got an email about this pdf-ocr converter. I haven't tried it 
myself, but for the $15 price drop for a lifetime license it seems worth 
checking out. Should be possible to invoke a (OSX) shell command to do 
the conversion.


The usual caveats about ocr accuracy apply, of course.

Re: Need trig & LCB help

[hh via use-livecode]

Replace the last part of your handler with the following.

variable tBNum as Number
variable tBCenters as List

put tBigRad - tLilRad into tInnerRad
put the number of elements in mData into tBNum
put regularPoints([tBNum,tInnerRad,tBigX,tBigY]) into tBCenters
repeat with tButtonNumber from 1 up to tBNum
   fill circle path centered at tBCenters[tButtonNumber] \
with radius tLilRad on this canvas
end repeat

-- returns list of N regular (=evenly spaced) circle points 
-- starting at high noon, turning clockwise
-- pL = [numOfPoints,radius,centerX,centerY]
handler regularPoints (in pL as List) returns List
  variable tI as Number
  variable tPi as Number
  variable tPts as List
  put 2*pi/pL[1] into tPi
  put [] into tPts
  repeat with tI from 0 up to pL[1]-1
push point \
[pL[3]+pL[2]*sin(tI*tPi), pL[4]-pL[2]*cos(tI*tPi)] onto tPts
  end repeat
  return tPts
end polyPoints

[Untested, right out of my head, should work.]

Re: drag'n'drop in text fields

I disagree. Having these commands allows developrs to precicely control what 
happens during a drag and drop operation, or to prevent drag and drop if they 
want to.

I, for one, would consider user-driven pasting of text or user driven

this an engine bug rather than a documentation bug.

Need trig & LCB help

[Pink via use-livecode]

In a nutshell, I am working on a widget that consists of a wheel with
buttons. Currently I've just manually calculated out where 8 buttons go, 
and
it works well, but I am trying to set it up with a user definable number 
of

buttons contained in array "mData."

Need help checking my math (and LCB syntax.) I took out some of the 
syntax

like setting paints and some other fluff, this is just calculating the
positions of each circle.

-- tBigRad is the radius of the main circle across the widget
if my width > my height then
  put my height/2 into tBigRad
else
  put my width/2 into tBigRad
end if

-- tLilRad is the radius of each small button around the edge
put tBigRad/4 into tLilRad

-- finding the coordinates of the center of the main circle
put my width/2 into tBigX
put my height/2 into tBigY
put point [(my width/2),(my height/2)] into tCenter
fill circle path centered at tCenter with radius tBigRad on this 
canvas


-- create an "inner circle" by subtracting the radius of a button 
from

the radius of the main circle
put tBigRad - tLilRad into tInnerRad
-- calculate angle in radians from the for the center of each button
put (the number of elements in mData)/(2 * pi()) into tButtonAngles

repeat with tButtonNumber from 1 up to the number of elements in 
mData

  put tInnerRad * (tButtonNumber-1 * tButtonAngles) into tAngle
  put tBigX * cos(tAngle * pi()) into tButtonX
  put tBigY * sin(tAngle * pi()) into tButtonY
  put point [tButtonX, tButtonY] into tButtonCenter
  fill circle path centered at tButtonCenter with radius tLilRad on 
this

canvas
end repeat

Re: drag'n'drop in text fields

[Brian Milby via use-livecode]

It looks like selectionChanged only reacts to explicit user events (mouse click 
or cursor moved via keyboard navigation).  If I select a chunk of text in 
another app and drag it in, the same thing happens (it is selected but no 
selectionChanged message).  If I script a button to select a chunk, no message 
either.  No message is sent when you cut/paste over/delete a chunk of selected 
text.  When you paste in text, the selection changes (cursor position moves) 
but no message is sent.

I did my testing on a Mac.

I think it is probably more of a documentation issue based on how it works.

Thanks,
Brian

True, works here also, sorry all for the wrong info.
[Looked at my earlier tests. The problem there was the msgbox (kept hidden).]

an up-to-date browser widget/libbrowser,
'set my rectangle',
basic keyboard support,
base64Encode/Decode (this is nearly done),
call JS from LCB without using a browser widget.

AHA! Now I get it (I think)! 8-)

Well my first professional job as a musician (bass player) was at "Circus 
Roncalli" 
in 1986, where I spent several months, so anything DRAGxxx related is not new 
to me 
nor something I am afraid of at all, if you know what I mean. :-)
