Please provide more information.

What exactly do you want to scroll?

Which way to scroll, etc.

You can make a textbox act like a scrollable label.

See attached.

@keith

Did you make sure that there was more text than can display in the TextBox?

I believe that may be the reason.

@Everyone

One drawback of this method is when dragging up and down, the selection menu may display and the insertion icons for selecting text.

We still need a TextBox.ReadOnly property if this method is going to fly.

@Scott Ferguson

yes, because it is the same text in the example, in fact the text was cut and i cant see the continuation in bottom,

Okay, here's another shot at it using a label and a thin canvas on the right side.

I was going to add a drag and segment operation to the canvas to continually

refill the label from a moving middle of the text, but I noticed the label

scrolled fine as is.

I missed the part about the button at the bottom.

It's possible using screen arrangements, and a draggable ball in canvas

to refill the label from a segment of the original source.

See attached.

FYI - Testers needed - ABG

I have just updated ai2-test.appinventor.mit.edu to have code which should be in our next release, currently scheduled for mid-week this coming week.

This *is* a Component release, but the old Companion will mostly work (all but the new Scrollable arrangements will work with the old Companion). For testing ai2-test will ask to auto-update your Companion to the test version (2.37t2).

Release notes can be found here.
