| Graphics ContextsGraphics Contexts — A shared pool of GdkGC objects |  | 
Description
These functions provide access to a shared pool of GdkGC objects.
When a new GdkGC is needed, gtk_gc_get() is called with the required depth,
colormap and GdkGCValues. If a GdkGC with the required properties already
exists then that is returned. If not, a new GdkGC is created.
When the GdkGC is no longer needed, gtk_gc_release() should be called.
 
Details
gtk_gc_get ()
GdkGC*      gtk_gc_get                      (gint depth,
                                             GdkColormap *colormap,
                                             GdkGCValues *values,
                                             GdkGCValuesMask values_mask);
Gets a GdkGC with the given depth, colormap and GdkGCValues.
If a GdkGC with the given properties already exists then it is returned,
otherwise a new GdkGC is created.
The returned GdkGC should be released with gtk_gc_release() when it is no
longer needed.
| depth: | the depth of the GdkGC to create. | 
| colormap: | the GdkColormap (FIXME: I don't know why this is needed). | 
| values: | a GdkGCValues struct containing settings for the GdkGC. | 
| values_mask: | a set of flags indicating which of the fields in valueshas
been set. | 
| Returns : | a GdkGC. |
