[REBOL] Re: specifiv position in area

Hi Thorsten,
try
view layout [
field silver silver
area silver silver
]
This should give you the save color in fields & areas when in focus as when out of focus.
Of course you can use any color in place of silver.
Cheers Phil

Hi Brett,
your new sample avoids the crash of the window. During the weekend i found
some time to work on the code and found out what "system/view/caret" is for
(previously i didn't know that). So, the problem was that when i type some
extra lines and then want to insert some text in or behind the new lines, a debug
printout for "system/view/caret" returns none and gives an error for the
insert function. Your new code avoids this crash problem, but still lacks the
functionality of inserting text right after the new textlines.
I found out that just refocussing the area solves the problem like:
view layout [
a: area "place your cursor then click button" button "insert" [
focus a
;--a/line-list: none ; *Forces recalculation of line offsets.
system/view/caret: insert system/view/caret "<inserted>"
show a
]
]
This solves the problem, but is not very nicefor a user, cause the window is
blinking due to setting the focus. Is there a way that when the area is
active it has the same color as being not active?
Perhaps you, as a more advanced Rebol-Programmer, have a more elegant way to
solve this.
