Craig,
You could also add
Code: Select all
send "scrollbarDrag" to field "fText"
to the end of the mouseUp handler of field "Make Overlay 4"
Also if the don't wrap of the field is set then adding to the script of field "fText"
Code: Select all
if the vScrollbar of field "fText" then
subtract the scrollbarWidth of field "fText" from item 3 of tTextFieldRect
end if
helps
Kind regards
Bernd

You and I can go back and forth forever tweaking this.
But what does Zax want to do? There is the "text" way, and the "kludge" way.
Which way?

Waiting for Zax, cleaned up an issue with horizontal scrolling with one or more long lines of unwrapped text. Still not perfect as regards the vertical scrollbar.
When we get to v.42 we will be done.

Craig,
add
Code: Select all
on ScrollbarDrag
lock screen
put the uStartLine of field "overlay" into tStartLinle
put the uEndLine of field "overlay" into tEndLine
put the rect of field "fText" into tTextFieldRect
if the hScrollBar of field "fText" then
subtract the scrollbarWidth of field "fText" from item 4 of tTextFieldRect
end if
## add this <--------------------------------------
if the vScrollbar of field "fText" then
subtract the scrollbarWidth of field "fText" from item 3 of tTextFieldRect
end if
-------------- end add this
-- more code
-- more code
Kind regards

Wow, very impressive!
I didn't know about
the formattedRect and your use of it opens up great perspectives for me. Also, the
blendDarken ink is smart.
In absolute terms, we could dream of a future version of LC which would manage a few more HTML tags, like "<br>" for example.
In any case, thank you very much Craig and Bernd.

Zax.
So which way are you leaning?

Well, I am leaning my way only because it takes less work.

It’s a personal standalone that is currently being developed.
The method which adds an overlay field is much simpler to use than the one which adds/removes ASCII 11 characters but it can be more complex if I need several highlights in a large scrolling field.
At this stage of production, I haven't decided yet.

Of course you could use both methods in different situations.

I am naturally lazy, so I always look for the simplest and easiest way to do things: of course these ways are not always the best.

The kludge way can easily support multiple overlays. Just give Bernd and I free rein.

Why do quite a few things that might have been expected to be fundamental to LiveCode come down to awkward kludges or work-arounds?

In this case they gave us ascii 11 back in LC 5. For myself, I prefer the text method because it requires no scrolling scripts, no additional controls, etc. Whatever method is used to calculate the text block in the overlay method can also be used to replace returns. Or you should be able to note the selection position in enterField and again in closeField to define the area.

Indeed, all you need is ASCII 11 and no overlays or anything else.

There is no question that the "text" way is the grownup way.
