How do I suppress garbage collection cursor in runtime?

Replace Cursor.GarbageCursor with any other cursor if you wish,

Cheers!

Hi,
 
I'd like to suppress the "trash can" cursor when there's garbage
collection going on in runtime.
 
Is there an easy way to do this?
 
Cheers,
 
Stewart

Hi Boris,

Good idea. However, I am setting the cursor dynamically, so I'd have to
set it to what ever is my current cursor so that it doesn't appear to
change - which seems a bit cumbersome.

I'd just like to switch it off. I guess I can just set it to whatever is
current, but I haven't found where that happens as yet... and it's too
late to look now...

Cheers,

Stewart

In that case you could override,

Cursor class>>garbage
 ^self currentCursor

Cursor class>>quickGarbage
 ^self currentCursor

Hope this helps,

-Boris

I would either redefine the senders to not use showWhile: or better create a NullCursor class which implemented showWhile: as a noop that simply evaluates its block argument and install it as Cursor.GarbageCursor.  You can then easily toggle between your production and development treatments of the garbage cursor.

I ran into something like this before, and I wish that each cursor had
been its own class.  That would have made things easier.

But since it was not the case, and from what I had to do, I'd do it
this way.  Implement isGarbageCollectionCursor in Cursor, then refine
beCursor to do nothing is self isGarbageCollectionCursor.  Not very
pretty because of all the == you will have to send in the test
message, but it does the job.
