GC.gtk_new介绍

[英]Invokes platform specific functionality to wrap a graphics context.

IMPORTANT: This method is not part of the public API for GC. It is marked public only so that it can be shared within the packages provided by SWT. It is not available on all platforms, and should never be called from application code.
