| Since I am using gtk with a
touchscreen application, I have no keyboard.  However, I am using a
treeview widget and intend to have supporting button widgets to allow the user
to scroll through the rows within the treeview widget.  My challenge is
that I need to indicate to the treeview widget how many rows to scroll up or
down.  Any suggestions on how to do this?  I know I can position the
cursor based on a path.  However, that may be tricky in that the user may
or may not have the sections within the tree expanded or not.  Also, I
would have to track how many rows are currently displayed within the current
treeview. I other words, I need to emulate the
user scrolling through the treeview by line, by page, or to the beginning or
end.  I think the begin or end would not be too bad.  Thanks, Bill |
