Nativve scroller scroll down as text input

Hi,
I made a field with a scroller scrolling down as text input. so the users don't have to manually scroll down to see the next line below visible area of the field.
The height of field "content" is 100. if the text reaches beyond 100 (height) of field, scroll sets down to the formattedHeight of field to show new line.
The problem is the scroller does not adopt increased height of the field..I put the script in the field like..
Code: Select all
--#1create scroller first( mobileControlCreate "scroller", "GroupScroll")
on keyUp
if 100 < the formattedheight of field "content" then
set the vScroll of group "scrollarea" to the formattedheight of field "content"
end if
end keyUp
The thing is, after put texts over the height 100 of field, I can not scroll up to the top of the field fully . It seems that the scroller does not adopt increased height of the field yet the field just shows the last line(newly created line) as I put text into the field.
Is there any way to solve this issue??
Cheers,
Louis

Hi Louis,
Not sure how to solve the problem you built for yourself but;
Code: Select all
on textFieldChange
set the vscroll of me to 10000
end textFieldChange
That in the field script is working.

Hi Simon,
Yes your suggestion is equally working but the real problem is users can't scroll back to the first line of field after putting a lot of lines(& scroll bottom of fld )..There must be way to solve this issue..

Hi Louis,
Not sure I follow?
Hitting the up arrow scrolls to the top just fine.
How did you want to scroll back to the top?

Hi Simon,
Oh I think we were taking different things
I was talking about the native scroller. There is no arrows because it is not the built in scroller in the field.
Is it possible to have same effect with built in scroller just like a native scroller of device?
I wonder how other developers could achieve creating text field enables swipe up and down with touches...

Hi Louis,
Ahh native scroller, didn't say that before.
Will have to work on this a bit more.

Hi Louis,
If you use a native multiline text entry field it works the way you want.
Code: Select all
mobileControlCreate "multiline", "myTextFld"
mobileControlSet "myTextFld", "visible", true
mobileControlSet "myTextFld", "rect", "50,50,200,200"
No other code needed.
Must it be just a native scroller?

Hi Simon,
Thanks for your suggestion. I tried it before I decide to use only LC field. unfortunately I found some problem that I couldn't manage..
The screen partially darkens as I select text of native multiline & touch buttons appears at the top.
The screen blackens out partially yet hidden buttons(in blackend part) are still working fine.
I attached picture showing how this problem look like. Please see it and let me know if you know any solution for it.
Thanks in advance,
Louis

Sorry that is a different problem not part of your original post.
The native text field does work as you wanted?

Hi Simon,
Native field works perfectly but it can not be used due to the darkening issue(see picture above). Have you heard of this issue? It could be a bug..If this can be fixed, I definitely will use a native text field.
Cheers,
Louis
