Firstly, I am new to allegro and I am not a scripter.
I am using script mentioned below for scrolling worksheet up & down by mouse wheel, but I am facing the problem for vertical scrolling as it stops between the design & dosent allow to scroll downwards. Horizantal scrolling works perfectly.
# use scroll button on mouse to scroll vertically
button wheel_up "roam y -$roamInc"
button wheel_down "roam y $roamInc"
# use shift + scroll button on mouse to scroll horizontally
button Swheel_up "roam x -$roamInc"
button Swheel_down "roam x $roamInc"
Also I can access my worksheet only upto (-128, 161) mm in X direction & (71, -128) mm in Y direction.
How can I increase worksheet size?
