1. VEL005 Questions
Hopefully somebody out there can lend a hint or two (or complete solution):
1. How do I apply strikeout to selected text when the user presses
<BACKSPACE> or <DELETE>?
2. How do I tell the window (RICHTEXT) *NOT* to wrap text?
3. How can I make the cursor advance word-to-word, instead of
character-to-character? IOW, when I press the <Left Arrow Key>, it jumps to
the beginning of the next word instead of moving the cursor to the next letter.
4. How to I fully justify text, especially if it's just one line of text
and I need it to stretch all the way.
5. How would I print the text from the RICHEDITOR? Can I specify only
certain pages to print?
Thanks!

Try this... using <BACKSPACE>,
procedure RichEdit1OnKeyPress(integer id, integer p, integer q)
.
.
if p = 8 then
y = GetAttribute(RichEdit1,SELSTART)
SetAttribute(RichEdit1,{{SELSTART, y-length(word)}})
SetAttribute(RichEdit1,{{SELLENGTH, length(word)}})
SetAttribute(RichEdit1,{{SELRICHSTYLE, "strikeout"}})
end if
.
.
end procedure
Of course, a lot of other stuff will have to be done beforehand. Like
figuring where the word starts in the line and consequently, it's length.
But that should get you started.
>2. How do I tell the window (RICHTEXT) *NOT* to wrap text?
SetAttribute(RichEdit1,{MEMOSCROLL, BOTHSCROLL})
SetAttribute(RichEdit1,{WORDWRAP,FALSE})

Same as strikeout above... providing you can figure out when the arrow keys
are pressed. I'm not sure you can do that the way it's currently set up.
>4. How to I fully justify text, especially if it's just one line of text

Have you tried PARAALIGNMENT? That allows you to justify text.
>5. How would I print the text from the RICHEDITOR? Can I specify only
>certain pages to print?
If you want to print RTF formatted text... the print option will be in
version 0.06. Otherwise, you can print it from Euphoria.
