Hi All,
I have a main window which includes an NSProgressIndicator - updated
every half hour to reflect the download usage from a local ISP. The
application works fine, but it has a behaviour that seems a little odd
and I'm hoping someone can help me.
The application also makes use of
[myMainWindow setHidesOnDeactivate:TRUE];
So that the application auto hides if another application is in the
foreground (it's an option).
Anyway, I've found that CPU usage for the application is at around 15%
if the window is hidden in this way, but if I hide the application from
the menu or COMMAND-H, or minimise the window, CPU usage is at 0%.
Can anyone give me some idea why this is the case, and how I can stop it?
I do know that it is the NSProgressIndicator that causes the problem
(probably because even though it is determinate, it still animates
slightly with the blue slowly moving, so that is what is taking the
CPU). If I take out the progress indicator, the app sits at 0% when
hiding on deactivate.
Any help is appreciated.
Thanks.
Jamie
