Hello,everybody!
I want to create a window in gimp plugin,so this is my code(part of the
plugin):
/static void run (const gchar *name,
gint nparams,
const GimpParam *param,
gint *nreturn_vals,
GimpParam **return_vals)
{
static GimpParam values[1];
GimpPDBStatusType status = GIMP_PDB_SUCCESS;
GimpRunMode run_mode;
GtkWidget *window;
gtk_init();
/* Setting mandatory output values */
*nreturn_vals = 1;
*return_vals = values;
values[0].type = GIMP_PDB_STATUS;
values[0].data.d_status = status;
/* Getting run_mode - we won't display a dialog if
* we are in NONINTERACTIVE mode */
run_mode = param[0].data.d_int32;
window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
gtk_window_set_title(GTK_WINDOW(window),"hello");
gtk_widget_show(window);
gtk_main();
}
/but when I ran the plugin in gimp,it didn't work...
and this is the error message:
