Is it possible to control the scroll bars in a window?

[Glen Duncan]

I have a Logitech G13 game controller that I would like to adapt to use for CAD (Eagle PCB) under Linux. The controller has a small joystick under the thumb position. The G13 user space driver can be configured to make the joystick send either mouse or keyboard events. I would like to have mouse events from the G13 scroll window view in Eagle. xdotool seems to be the only way to have external programs send window events to other programs, but from what I've seen in the documentation, there doesn't appear to be a way to target scroll bars. Am I missing something? Is there another tool or method I should look at? Thanks!

I don't know anything about "Eagle" or "G13 scroll window", but with
xdo, you can send mouse "clicks". mouse wheel-driven scrolling is
basically a series of "clicks", iiuc.

As the documentation for xdotool(1) says:

>> click [options] button
>> Send a click, that is, a mousedown followed by mouseup for the

so if what you care about is scrolling (and not the scroll bars
themselves), maybe you can just send these scroll-triggering events to
the window with xdotool?

I don't see why sending scroll events would be a problem.

Scroll wheels of mice send  Buttons 4 and 5 events to indicate the user has moved the scroll wheel

just send those events to the appropriate window (or sub-window).

WARNING: watch out for 'state' settings (eg: shift, ctrl, meta, super, numlock)

If these are active some applications will not recognise the event (others will).

I talk about this sort of thing in generating events (mostly for keyboard macros).
