Re: [xstep-devel] broadcast++ correct version...

[Marcelo S. <mar...@bs...>]

yes, but in the version 4.0 you have a direct control of 
event loop. when you have a non-animated application, you can 
just use:

	while(XSCheckEvent(desktop,XS_BLOCK));

and you application will work like a version 3.x application
with animation=0. if you have a animated application, like a
game or a video player, you can use:

	while(XSCheckEvent(desktop,!XS_BLOCK)) usleep(1);

in this case, !XS_BLOCK of version 4.0 is just like 
animation=1 of version 3.x. but in version 3.x you have a 
implicit usleep(1) in library code, in the version 4.0 you can 
decide if you have this usleep() or not. of course, you will need 
a usleep() to control the rate of your event loop, for 
example, usleep(1000000/15) to fix a 15 fps loop.

but animations and updates are not equal. the broadcast++ 
equivalent in xstep 4.0 is a desktop->global->count++. of course,
this global struct is replicated in any widget, then you
can use any wid->global->count++. when a event is checked,
the change function of all widgets are checked until 
cont is zero.
