Hi,
I have a gtk program doing now and then a calculation taking a few secs.
To prevent freezing my appl. I want to use for Linux g_thread.
However, this is not supported for Windows in combination with gtk.
As far as I know the only possibility to solve this for Windows is using
an external program and call this by g_spawn_async. (Not a nice method; is
there another way?)
As far as I know g_spawn_async should work under Windows, but I can't get
it to work.
Below a test program; it works fine under Linux, but g_spawn_async returns
always FALSE under Windows.
(In this example g_spawn_async opens nedit. Note that the (now commented
out) 'system' call does work.)
(glib version is 2.16.3.)
#include "gtk/gtk.h"
static void post_process(GPid pid,int status,gpointer data)
{
// ext. program did end
puts("post_process");
}
main(int argc,char **argv)
{
char *sargv[2];
GPid pid=0;
gtk_init(&argc,&argv);
sargv[0]="nedit";
sargv[1]=NULL;
//system(sargv[0]);
if (g_spawn_async(NULL,sargv,NULL,
G_SPAWN_DO_NOT_REAP_CHILD | G_SPAWN_SEARCH_PATH,
NULL,
NULL,&pid,NULL))
{
g_child_watch_add(pid,(GChildWatchFunc)post_process,NULL);
gtk_main();
}
else
{
puts("ERROR!");
}
}
