Hi,
I'd like to imitate a mouse move event programmaticaly, to refresh the
state of my custom view.
What is the best way to do it?
I am trying to use [NSApp postEvent:atStart:] and [window
postEvent:atStart:], but nothing happens, the event is not fired, and
the view does not receive it.
Here
As I said, I am trying to refresh the state of the view after a
lengthy operation is complete. By state I mean that the item in the
view on which the mouse is hovered, should highlight. Also, if I don't
refresh, the view will not respond to the following mouse down event,
unless it is preceded

No disrespect, but you did not say that - this is the first mention of
a lengthy operation. How lengthy? What is it?. Not sure why the
coyness but
Thanks Graham,
There are basically two or three custom views of different class in
the window that need refresh. These views are totally custom, which
means I could of course implement the corresponding methods that would
explicitly refresh their state, but because the state depends on the
mouse

Graham,
Maybe I'm not speaking clearly, but that's exactly what I'm trying to
do -- use a mouse event to cause a state change, but in this case the
mouse event would be fake. Mouse position is in no way part of the
view's state. I just want that at particular moment the view's state

Untested suggestion: when a real mouse moved event occurs, NSLog it
and duplicate its arguments exactly. Perhaps the '0' arguments are why
it's not working.
If that doesn't do the trick, you'll probably have to drop to a lower
level, such as CGEventPost().
... but Graham's right - there's
Dave, I already tried CGEventPost() but it does not seem to work
either -- just nothing happens. I'd appreciate an example of working
code, I haven't been able to find any.
I also tried CGPostMouseEvent(). This works, but in a weird way -- it
actually moves the mouse cursor (kind of a too

Graham, I really appreciate you taking your time to write such
detailed posts for me, but what I am trying to say is that I am doing
everything exactly as you suggest, following the best design patterns
(I think). There is a controller and it maintains the selection. The
view only draws the

In other words, instead of faking a mouse event in order to get the
mouse position into that code, just factor that part out and give it
the mouse position at the end. You can get that using -

Oleg, had you thought of doing something like adding -isSelectionValid
and -setSelectionValid: methods to your controller class? The view
would always keep track of the mouse state, tell the controller what
the current selection is when the mouse moves, but won't update itself
