Re: [gtk-list] how to show GdkImlibImage?

[venugopal <venu iiithyd ernet in>]

Dear shigang,
	You have forgotten to render the image. You should really render
the image with gdk_imlib_render before copying the pixmap.Also, it far
better that you create a drawable and then draw the pximap onto it. It is
more efficient. You can also eliminate the problem of flicker and
implement double buffering if you adopt this approach.
