Hi Bob
Guess what. MouseRelease works if you click either side of the
thumbposition, but not if you click the thumb itself. Looking for another
handler for that.
Not all that surprising given this from the documentation:
"Sent when the user releases the mouse *outside* the control that was
clicked." (my bold)
How one differentiates between *mouseUp* outside and *inwith* the
clicked control is the question here.
ALSO: as the scrollBar is NOT a control in its own right rather than
part of a field one cannot
address message just to the scrollBar . . .
Of course, if a *scrollable text field* were to be a *composite object*
(c.f. datagrid)
whereby the scrollBar were an entity inwith a *group*
that also contained a field, things would be different.
The OTHER Q that comes up here is why, when I try to set up a composite
object
LC 8.1.7 will not let me set the orientation of a *scrollBar* to vertical?
No go via the props inspector, & typing this:
set the orientation of scrollBar "sBAR" in the Message Box
give no joy.
Richmond.
Could there be a more elegant solution? Something like a property or
behavior that resets a scrollbar to its normal size if it is not a focus?

Thanks bob. I replied to your first response. Mouserelease sounds good. I
didn't know if it and will try later.

Does mouseUp get sent to the control when you release the thumb pointer?

I have a set of scrollbars that are normally small, to preserve screen
space. But I want them to expand when mouse enters, so give finer
control,
then to shrink again when mouse leaves. I have managed to do this with
mouseEnter and mouseLeave.
Problem is that if I drag the thumb pointer with mouse down, by the
time I
release the mouse it is still down and outside the bounds of the target
scrollbar, so no mouseLeave is sent.
I could use "on idle" to test if the mouse is within, but that would
not be
efficient.
Suggestion please?
