1. setting text color in Rich Edit
Judith,
re: Rich Edit:
I assume you've found out that "cut" works ok in Win32Lib 0.53, but that
there's some difficulty getting user input text colorized.
Here's the best I have found, only problem is, it only works on text which
is *selected*:
in the RE example that comes with Win32Lib, in "procedure CF_onClick()",
(which is the "change font" procedure),
comment out "setFont( RE, {font[4],font[1]} , font[2], font[3] )"
(to remove the *effect* of the font selection dialog),
and add "setFont(RE, {Red,"Arial"}, 20, Normal)"
(to force the font to be Red)
then, when you run it, IF YOU SELECT SOME TEXT, and click "change font", and
in that dialog just hit "ok", it will change the *selected* text to Red. Of
course, the problem here is how to programmatically *select* the text, & I
haven't a clue how to do that.
At this point, (unless maybe someone knows how to programmatically select
text in an acceptable fashion), looks to me like what you did with your own
editor may be the better bet?

Its undocumented but the setIndex() routine can be used to select text on
RichEdit controls.
eg..
-- Select characters 30 - 43 inclusive...
setIndex(RE, {30, 43})
I should really update the docs on this one.

Derek,
Nice! I'll give it a try. I was busy trying to figure out how to use
"EM_SETSEL", but yours looks easier.
Thanks!

4. Re: setting text color in Rich Edit
Derek,
That helps a lot for text already in the RichEdit. But lets pretend we have
a text file - or whatever not already richEdit - and want to colorize it as
we putStream or before we putStream?
Do you know a solution to that?
I suppose we could kludge it and inspect the data after streaming into the
RichEdit and colorize it then but it seems it would be faster to colorize as
we putStream.

5. Re: setting text color in Rich Edit
Derek,
Sorry, should have asked this in last post but didn't think of it in time:
is there some way to get the POSITION of the *cursor* in the Rich Edit
control? (That, plus test for keywords, plus your selection trick, plus
setFont might effect keyword colorizing in the Rich Edit.)

6. Re: setting text color in Rich Edit
Judith,
I *think* in order for a file to get "naturally" colorized as it Streams in,
it has to have been *saved* in some ".rtf" format; but since what's *in* the
Rich Edit control is what would be saved, if it were colorized by Derek's
trick *as it were typed* (similar to what David has happening), then it
would (nearly automatically?) be saved in that format?? Then when it
Streams in, presto, auto color.

Yeah, but the exe exw might not like Richtext format and I don't want to
write out two files, one to reload with and one for Euphoria.

9. Re: setting text color in Rich Edit
Dan and David,
Good news! The method works! We can now use RichEdit if we want to in the
IDE editor. That would sure simplify things.
Thanks Dan for getting us started on this today.
Judith
10. Re: setting text color in Rich Edit
Judith,
Well, that's wonderful! But I'm curious as to what you did; I wasn't able
to find any way to know where the cursor *is* in the Rich Edit (to know what
position values to use to select text to color the keywords as they're
entered), nor could I think of anything to colorize while Streaming. I
couldn't ever figure out how David got the cursor to be initially present in
his "generic" example (ie, without first mouse clicking).
Anyway, good work, glad I said something that helped, gotta catch some zzz's
now.

11. Re: setting text color in Rich Edit
Hi Dan/Judith
you can use getIndex(RE) which returns an atom that tells you where the
insertion cursor is.
The next win32lib also has getSelection(RE) which retruns a two-element
sequence containing the character positions of the start and end of any
selected text.
These functions also work with MleText and EditText controls.

cheers
Derek.

12. Re: setting text color in Rich Edit
Here's what I found at
It's basically an excerpt from the RTF specification. It's probably easier
to save everything in text format, and color code on the fly. Set up your
color table at the beginning, and insert the color formatting as you go. To
color text on the fly, you could select the word in question, and replace it
with the rich text formatting.
Color Table
The \colortbl control word introduces the color table group, which defines
screen colors, character colors, and other color information. This group has
the following syntax:
<colortbl> '{' \colortbl <colordef>+ '}'
<colordef> \red ? & \green ? & \blue ? ';'
The following are valid control words for this group:
Control
Word Meaning
\redN Red index
\greenN Green index
\blueN Blue index
Each definition must be delimited by a semicolon, even if the definition is
omitted. If a color definition is omitted, the RTF reader uses its default
color. The example below defines the default color table used by Word. The
first color is omitted, as shown by the semicolon following the \colortbl
control word. The missing definition indicates that color 0 is the ''auto''
color.
\red0\green255\blue0;
The foreground and background colors use indexes into the color table to
define a color. For more information on color setup, see your Windows
documentation.
The following example defines a block of text in color (where supported).
Note that the cf/cb index is the index of an entry in the color table, which
represents a red/green/blue color combination.
{\f1\cb1\cf2 This is colored text. The background is color
1 and the foreground is color 2.}
13. Re: setting text color in Rich Edit
Matt,
I'll have to play with this & see what I can do; there's two "on the fly"s,
though: on the fly as text comes in from a file, and on the fly as the user
types into the Rich Edit "screen". The "hidden" <grin> cursor & selection
control functions should help with user entry colorizing, and I guess what
you just supplied would help with the input of a text file to the RichEdit
control.
Thanks!
Dan
