Thanks for the suggestions, but they don't work, unfortunately. I
think I'll just do a custom view like Quentin suggested.
Best,

Hi!
It's not easy to do that because NSProgressIndicator does not use a
cell for it's displaying :-(
With that hack you made, you have to be careful, because you add a
subview every time the tableView wants to draw that indicator cell. Or
does addSubview check out whether or not a view already was added
before ?
If you use a NSMatrix, you have the same problems because an NSMatrix
uses cells for displaying as well...
Try to run the progressViewer in a separate thread (to solve the
animation problem).
use
[progressView setUsesThreadedAnimation: YES];
for that.
But be careful: THe app gets multithreaded that way, which may not be
what you want.

Tobi
ps: These are only suggestions... I never tried to add progress
indicators to a table view yet... hopefully somebody who already did
will answer to this thread, too.

I know this has been discussed several times before, but I haven't
been able to find a satisfactory solution. I'm using the following
code I adapted from the archives in my NSCell subclass to attempt to
display a progress bar in my table view. The problem is with getting
the bar to animate properly. When I first open the window it's in,
it animates fine, until I resize the window, or click the table or
something, when it stops. It won't animate after that.
- (void)drawWithFrame:(NSRect)cellFrame inView:(NSView *)controlView {
[controlView addSubview:progressView];
[progressView setFrame:cellFrame];
}
To me this looks like a pretty hackish solution, but it's the closest
I've gotten this work.
I'm trying to implement a Mail.app-style activity viewer. Is a
tableView even the best way to do this? Perhaps an NSMatrix or
custom view would be easier?
Thanks,
