#include <gtk/gtk.h> GdkGC* gtk_gc_get (gint depth, GdkColormap *colormap, GdkGCValues *values, GdkGCValuesMask values_mask); void gtk_gc_release (GdkGC *gc);
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.
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 values has
been set.
|
| Returns : | a GdkGC. |
void gtk_gc_release (GdkGC *gc);
Releases a GdkGC allocated using gtk_gc_get().
gc : |
a GdkGC. |
