Hi,
Does drawing performance of SWT on a canvas or using draw2d increase
according to the system capabilities,
Like does having a high end graphics card will ensure good rendering
performance of draw2d,GEF,GMF....
---------------------
why, mr. Anderson, why, why do you persist?
Because I Choose To.
Regards,
Vijay

The general answer is yes, since SWT uses the OS' native facilities, any
available hardware acceleration that's applicable will be used when drawing.
Whether this translates into a noticable performance difference depends on
the case. For instance, different graphics card manufacturers may optimize
for different things (eg.- GDI, OpenGL, etc.). Also, graphics calls that
use GDI+ (eg.- those that require the use of GC.setAdvanced(true)) will not
be accelerated because GDI+ is software-based. These are the same factors
that influence whether any native app is helped out by hardware
acceleration.
