[maemo-developers] Another libosso bug?

[From: David Hazel]

The logic is comparable to what I'm doing. However, in my case I'm calling
osso_application_top in response to a user clicking on a button on my
application. When I first found it not working, it occurred to me that this
might be because the fact that the button was being clicked at that point
meant that my application was being forced to the front by the OS. To get
around this, I placed the call to osso_application_top inside a callback
function, which is activated by a 300ms timeout from the button-click
routine. In other words, a 300ms timeout is triggered by the button click,
and the callback routine that handles the timeout invokes
osso_application_top to bring the browser to the front. However, it still
doesn't work.

This is why I asked whether there were conditions under which
osso_application_top would not work. Presumably, if the application that
calls it is in the process of doing something that makes it the top
application, this would override the attempt to bring another application to
the front. The problem is, I can't think of any other way to trigger such an
event in response to a user action. By definition, this must be an action
that does something to my application's window, which means my application
has to be in front to deal with it.

Any suggestions as to what might be going wrong?

This works for me:

-----
#include <stdio.h>
#include <glib.h>
#include <libosso.h>

static GMainLoop *loop;

int main(int argc, char* argv[])
{
        osso_context_t *context;

        loop = g_main_loop_new(NULL, 1);
        context = osso_initialize("toptest", "0.1", 0,
                                  g_main_loop_get_context(loop));

        osso_application_top(context, "osso_browser", NULL);

        g_main_loop_run(loop);
        return 0;
}
