Hello everyone,
I have a little problem with the function
clutter_texture_set_load_async. Nothing is displayed unless a timer is
triggered or action keyboard or mouse is sent, here is my code:
#include <string.h>
#include <clutter/clutter.h>
void
load_finished (
ClutterActor *image,
GParamSpec *args1,
gpointer data)
{
printf("load_finished()\n");
clutter_actor_set_size (image, 100, 100);
}
int main(int argc, char **argv)
{
ClutterActor *stage;
ClutterColor black = {0x00, 0x00, 0x00, 0xff};
clutter_init (&argc, &argv);
g_thread_init (NULL);
// Stage
stage = clutter_stage_get_default();
clutter_stage_set_color (CLUTTER_STAGE (stage), &black);
clutter_stage_set_title (CLUTTER_STAGE (stage), "Async");
clutter_actor_set_size (stage, 400, 400);
// Load texture
GError *error = NULL;
const gchar *directory_path = "../cover";
GDir* directory = g_dir_open(directory_path, 0, &error);
if (error)
{
g_warning("g_dir_open() failed: %s\n", error->message);
g_clear_error(&error);
return 0;
}
const gchar* filename = NULL;
int x = 0, y = 0;
while ((filename = g_dir_read_name(directory)))
{
if (g_str_has_suffix(filename, "png"))
{
gchar* path = g_build_filename (directory_path,
filename, NULL);
ClutterActor *image;
printf("file: %s, x: %i\n", path, x);
image = clutter_texture_new ();
clutter_texture_set_filter_quality ((ClutterTexture *) image,
CLUTTER_TEXTURE_QUALITY_MEDIUM);
clutter_texture_set_load_async ((ClutterTexture *)
image, TRUE);
clutter_actor_set_position (image, x, y);
clutter_container_add (CLUTTER_CONTAINER (stage),
image, NULL);
// Connect load finished and set texture file
g_signal_connect (image, "load-finished", G_CALLBACK
(load_finished), NULL);
clutter_texture_set_from_file ((ClutterTexture *)
image, path, NULL);
x += 15;
y += 15;
g_free (path);
}
}
clutter_actor_show (stage);
clutter_main();
return 0;
}
