Hello again,
I posted before title:
Clutter and GTK-Clutter-Embed for Medical viewer
I use Fedora 15 64bit with gtk3-3.0.12, clutter-1.16, clutter-gtk 1.0.0 on a
Lenovo T61p laptop (Nvidia Quadro FX 570M) with Nvidia binary driver.
To illustrate my problem I created a minimal example: Three GTKClutterEmbed
Widgets in a HorizontalBox widget, drag_action and reactive enable on the only
actor in each stage. Now when I drag each actor in a row, the first time it
works, but then two of the three actors stop responding.
The errors I get:
<ERROR>
(clMedView:16773): Clutter-WARNING **: The required ID of 2236962 does not
refer to an existing actor; this usually implies that the pick() of an actor is
not correctly implemented or that there is an error in the glReadPixels()
implementation of the GL driver.
</ERROR>
I hope somebody can give me some advise.
Regards
Marc Geerlings
