[REBOL] Re: Fw: Scrolling text

Hi Scott,
Thanks for your message. At first I thought you had it! But alas... I've
been checking some more
and that extra show you put in makes it appear that the problem is fixed but
it is not. You can see this by scrolling
to the bottom of the area again and then instead of hitting the button click
in the field then click on the
button. The result is the area is back at the top again. :)
So I ended up doing some more digging and I believe it comes down to the
fact that the area and the field share the same PARA object which includes a
field that records the scroll offset.
>> layout [the-field: field the-area: area]
>> same? the-field/para the-area/para
== true
So in a new version if I ensure that area has a new para object different to
field - there is no problem.
view layout [
the-field: field "sample"
the-area: area 200x50 {This is some text that just happens
to run over multiple lines. If you
scroll to the bottom of this text
area using the arrow keys
you will see the text of this area
scrolling up.
}
button "Show" [show the-field show the-area]
do [the-area/para: make the-area/para []]
]
I suspect that area should get its own version of a para by default.
So I'll send this off to feedback. Thanks for your help!
Brett.
