Hi,

Is there a way to add progress monitor to DeleteCommand and more generally
to an EMF Command ?

Thank you for your response !

Sylvain,

I've never thought about it. It seems tricky. Does it really take that
long?

I'm using EMF 2.3 and I can have some nodes containing more than 100
subnodes.
So, when I use DeleteCommand for the parent node, it takes a while and
could frozes the application.

An idea of the best solution ? reimplement commands to add progres monitor
?

Thank,
Sylvain

Sylvain,

I'm really not sure how you will measure progress in a meaningful way.
Having a progress monitor come up when you do a "simple" delete might be
very annoying to the user. Unless your users are complaining, it seems
a lot of work with potentially negative gain...

Hi,
I agree with Ed, measuring the work would not be very precise here. Why
don't you just wrap your call into
org.eclipse.swt.custom.BusyIndicator.showWhile(Display, Runnable)? The
user would see an hour glass until the command has completed.

Kind regards, Sebastian
