I created a quick and dirty application that sets up the stage, creates
and then destroys the actor (in this case again a texture). Same problem
as before -- it crashes after destroying it. I did not use g_new0 this
time and instead of a show all before clutter_main I call show for the
actor and the stage separately. This was really irrelevant -- it makes
no difference.
The code is below and is fairly close to one of the examples in the 0.4
docs, less the callback and including the destroy (ref:
http://www.clutter-project.org/docs/clutter-animations.html).
There is a tarball of the code, header, image and makefile here:
http://clutter.enveria.com/wp-content/uploads/2008/02/texture_test.tar.gz
I pasted the output from gdb below the code itself after I ran the
program and then 'where'.
/* main.c */
#include "main.h"
int main (int argc, char *argv[])
{
ClutterActor *stage;
GdkPixbuf *pixb;
ClutterActor *actor;
clutter_init (&argc, &argv);
/* Stage Setup */
stage = clutter_stage_get_default ();
ClutterColor stage_color = { 0x00, 0x00, 0x00, 0x00 };
clutter_stage_set_color (CLUTTER_STAGE (stage), &stage_color);
clutter_actor_set_size (stage, 800, 600);
/* Actor Setup */
if((pixb = gdk_pixbuf_new_from_file ("image.png", NULL))== NULL)
{
printf("Oh, no! The image would not load!\n");
}
else
{
printf("Image loaded ... let's continue.\n");
actor = clutter_texture_new_from_pixbuf (pixb);
clutter_container_add_actor (CLUTTER_CONTAINER (stage), actor);
clutter_actor_set_position (actor, 200,300);
clutter_actor_show (actor);
clutter_actor_destroy (actor);
}
clutter_actor_show (stage);
clutter_main();
return 0;
}
