I am new to 2D stuff and for that matter with Gtk. I am trying to
develop an Xr based extension to Eclipse on Linux (Redhat 9). I am using
the Gtk version of eclipse. I am trying to use drawing with and without

In the SWT programs paint() method, I have the following objects at

* A GtkWidget object that represents the SWT Shell that I am drawing on

* A GdkGC object that represents the GC that I need to draw on

* For use in double buffering, I can also create a SWT Image object,
which encapsulates a GdkPixmap object.

I am using a JNI layer library to link the Java world to the C world.
The JNI layer basically exports the Xr API into Java plus some
convinience functions to set drawables.

I have tried a whole bunch of arguments to XrSetTargetDrawable()

The 'drawable' arg that I tried are

1. GDK_DRAWABLE_XID(widget->window)

2. I do not understand what to do with the GC object

3. In double buffering case GDK_PIXMAP_XID(gdkpixmap) as the arg to the
'drawable' parameter.

None of them seem to work and I cannot understand why.

Does anyone in the list have a working example that uses Gtk and Xr

Any help or advice in this regard is greatly appreciated.
