Thanks for this. I also wasn't aware you could hide individual lines in 
a field, and I have now refactored the glx2 script editor's code-folding 
feature to do this instead of storing/deleting and restoring lines of 
htmltext.

Re: Set the imagesource of a character to a built in graphic

[Bob Sneidar via use-livecode]

In this case the only thing I am trying to hide is all the subtext between the 
main lines starting with the line clicked on. It's always going to be a 
contiguous chunk, and nothing will change the contents of the field except my 
scripts so that is good. 

Not sure about the metadata property, but I want to make sure that if the user 
clicks anywhere else except for the +/- icon, nothing happens. That is why I 
check for the clickChar.

Yes, but depends on the scenario: Sometimes I find it more safe to walk
through the range (for j=tStartLine to tEndLine) and check the hidden
of each single line, because the hidden of a range may have been changed
by changing the range elsewhere.

Also: Did you already try to use the metadata property for a chunk instead

Re: Set the imagesource of a character to a built in graphic

[Bob Sneidar via use-livecode]

Richard, that is kind of what I was seeing with replace in field. Very dicey. 
So I decided to see if I could use the hidden propery method to work. Here is 
what I came up with. Remember that char 1 of the 1st level lines are spaces, 
and the 1st char spaces in those lines have the imageData set to a + graphic so 
clicking on the + will expand and collapse the line. The second level lines do 
not start with spaces, so I can use that to discriminate between first level 
lines and others (I supose I could have checked for the imageData but what the 
hell):

on mouseUp
   put the clickChar into tChar
   if tChar is not space then exit mouseUp
   put word 2 of the clickLine into tLine -- the line number of the line clicked
   put the text of me into tText
   put tLine +1 into tStartLine

   repeat with i = tStartLine to the number of lines of tText
  if char 1 of line i of tText is space then
 exit repeat
  end if

  put i into tEndLine
   end repeat
   
   if char 1 of line tEndLine of me is space then exit mouseUp -- there are no 
sub-lines

   if the hidden of line tStartLine to tEndLine of me is true then
  set the hidden of line tStartLine to tEndLine of me to false
   else
  set the hidden of line tStartLine to tEndLine of me to true
   end if
end mouseUp

OK, I didn't know about the paragraph property.

set the visible of paragraph 2 of fld "fldList" to false
 this does make a line disappear, but apparently keeps the value in memory
so that it can be restored.

It works seemingly well, even with chunk expressions, e.g.:

  replace "i" with "X" in line 1 of fld 1 preserving styles

But I found it also does something very weird:  in my test the 
imageSource was applied to the first "i" in the field, and after the 
replace command there was now an "X" immediately before the rendered image.


So while it was good to see the image still rendered, if the "i" was now 
replaced with "X" and the "X" is visible, what is the imageSource 
attached to?


It seems it's attached to nothing.  Getting the htmlText of the field 
after the replace command shows no  tag at all.

Re: Set the imagesource of a character to a built in graphic

[Bob Sneidar via use-livecode]

I looked at the widget. Not sure how to use it. I got an object with a + 
control which apparently creates custom property keys and displays it in the 
field. I could probably make that work, but I probably won't have a lot of 
control over the appearance. I got the thing working by manipulating the HTML 
text. 

The goal will be to create an object library where I can select an object, be 
it a group, button, field or menu (I know it's a glorified button) and then in 
a palette add that object to a list where each object class is 
expandable/collapsable. 

I have certain fields and buttons which have custom scripts and properties 
which control how they behave in my apps. I am trying to create a kind of 
Library app that will allow me to change a few settings then "drop" the object 
onto a card. 

I will have to be able to add and delete objects to this list, while copying 
the actual object to the library somehow. If it works the way I would like, I 
will be able to create and customize objects one time, then drop them any 
number of times. 

Behaviors work well for scripts, but there is no "behaviors" for properties. I 
suppose they would be called "templates" if they existed. I suppose I could 
simply provide a list of properties and let the user check off the ones they 
want to include in a "template" but there are so many properties this would 
become cumbersome pretty quickly. Also, that would not handle more complex 
objects like groups.

Thanks Mark. That solves half the problem. I would have to know the actual 
character of the cr before the line I am trying to insert text before to do 
something like 

put "this is a test" & cr before line 3 of field "Scrolling List Field"

I can work around it I am sure. As long as I know that what I am seeing is not 
a bug, but is the way the vanilla replace command works, I won't go barking up 
trees.

ImageSource is sort of like text styles, you can see it most clearly in 
the htmlText of a field. An imageSource is represented by tags just like 
bold, italic, and other styles. You'd see the same behavior if the lines 
were bold instead of having an imageSource.


Inserting some lines into a field doesn't change the styling of the 
other lines, it just adds some additional unstyled text.


The replace command works only on plain text and in this case the script 
is passing the entire content of the field. The replace command gets the 
full text, does the replacement, and puts the text back. As far as it's 
concerned, the imageSource characters are just spaces. Styling tags are 
ignored and consequently stripped out.


You can either get the lineOffset of the unwanted lines and delete only 
those, which leaves the htmlText intact elsewhere, or you could get the 
htmlText of the field, do the replacement, and then set the field's 
htmlText to the revised content.
