Re: [maemo-developers] gtk, gstreamer movie window = problem
Hi!
I tried to solve this problem but still the same happens. I'm running
program from xterm so I think I don't need osso_initialize(), and on
console I don't get any error messages. This is code I'm using (I'm
out of ideas what can be wrong):
//main gui function
gui(){
HildonProgram *app;
/* Create the hildon application and setup the title */
app = HILDON_PROGRAM (hildon_program_get_instance ());
g_set_application_name (Menu Example App);
/* Create HildonAppView and set it to HildonApp */
appview = HILDON_WINDOW (hildon_window_new ());
hildon_program_add_window (app, appview);
/* Create menu for view */
create_menu (appview);
///box1 = gtk_hbox_new (FALSE, 0);
///box2 = gtk_vbox_new (homogeneous, spacing);
///label = gtk_label_new (Volume:);
///gtk_misc_set_alignment (GTK_MISC (label), 0, 0);
///gtk_box_pack_start (GTK_BOX (box2), label, FALSE, FALSE, 0);
///gtk_widget_show (label);
///adj1 = gtk_adjustment_new (1.0, 0.0, 4.0, 0.1, 1.0, 1.0);

///gtk_box_pack_start (GTK_BOX (box2), scale, TRUE, TRUE, 0);
///gtk_box_pack_start (GTK_BOX (box1), box2, expand, fill, padding);
content = gtk_event_box_new ();
gtk_container_add (GTK_CONTAINER (appview), content);
GstBus *bus;
bus = gst_pipeline_get_bus (GST_PIPELINE (pipeline));
gst_bus_set_sync_handler (bus, (GstBusSyncHandler) create_window, NULL);
gst_object_unref (bus);
g_signal_connect (content, expose-event, G_CALLBACK (cb_expose),
videosink);
//gtk_box_pack_start (GTK_BOX (box1), content, TRUE, TRUE, padding);

}

return GST_BUS_DROP;
}
cb_expose (GtkWidget * w, GdkEventExpose * ev, GstElement * e)
{
if (GST_IS_X_OVERLAY (e)
!GTK_WIDGET_NO_WINDOW (w) GTK_WIDGET_REALIZED (w))
{
gst_x_overlay_set_xwindow_id (GST_X_OVERLAY (e),

}
}
As described in
http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-base-libs/html/gst-plugins-base-libs-gstxoverlay.html#desc
you need to set it in a message handler in order to set it at the right time.
This sounds indeed like the element creates the window itself instead
of using the one you want.

Depends, if you
a) have a .desktop file for it
b) define a service there
then you need to call it, otherwise it won't matter I guess... (in the
will it be killed context).
This is code I'm using (I'm

content = gtk_event_box_new ();
gtk_container_add (GTK_CONTAINER (appview), content);
GstBus *bus;
bus = gst_pipeline_get_bus (GST_PIPELINE (pipeline));
gst_bus_set_sync_handler (bus, (GstBusSyncHandler) create_window, NULL);
gst_object_unref (bus);
g_signal_connect (content, expose-event, G_CALLBACK (cb_expose),
videosink);
//gtk_box_pack_start (GTK_BOX (box1), content, TRUE, TRUE, padding);
///gtk_container_add (GTK_CONTAINER (appview), box1);
///gtk_widget_show (box1);
gtk_widget_show_all (appview);
g_signal_connect(G_OBJECT(appview), delete_event,
G_CALLBACK(item_close_cb), NULL);
}
//callback functins

create_window (GstBus * bus, GstMessage * message, GstPipeline * pipeline)

You are creating this again here ;)
gst_x_overlay_set_xwindow_id (GST_X_OVERLAY
(GST_MESSAGE_SRC (message)),
content-window);
You are giving the window pointer to the function, instead of the X id
of it. Use the GDK_WINDOW_XID() macro to get the X window id for the
window.
You also need to be sure the GdkWindow of the event box is already
created when you set it (otherwise the window pointer might be NULL or
whatever), this can be done by calling gtk_widget_realize() on the
event box. I suggest doing it just before entering the gtk main loop.
cb_expose (GtkWidget * w, GdkEventExpose * ev, GstElement * e)
{
if (GST_IS_X_OVERLAY (e)
!GTK_WIDGET_NO_WINDOW (w) GTK_WIDGET_REALIZED (w))
{
gst_x_overlay_set_xwindow_id (GST_X_OVERLAY (e),
GDK_WINDOW_XWINDOW (w-window));
}
}
This should be removed too, as it may conflict with the setting above
(and the call to gst_x_overlay_set_xwindow_id() should happen exactly
once AFAIK).

[maemo-developers] gtk, gstreamer movie window = problem
Hi!
In my gstreamer movie player I have connected gstreamer movie window
with gtk menu (gstreamer window is inside gtk app window) using this
code:
static void
cb_expose (GtkWidget * w, GdkEventExpose * ev, GstElement * e)
{
if (GST_IS_X_OVERLAY (e)
!GTK_WIDGET_NO_WINDOW (w) GTK_WIDGET_REALIZED (w)) {
gst_x_overlay_set_xwindow_id (GST_X_OVERLAY (e),
GDK_WINDOW_XWINDOW (w-window));
}
}
(...)
g_signal_connect (content, expose-event, G_CALLBACK (cb_expose),videosink );
Everything is ok when I start app (movie window is in right place in
app window) but when I click on some item on maemo system menu (right
top border of the screen ) eg. volume control and I click back on my
app, window with my gtk elements disappears (probably is killed) and
gstreamer movie window is the only window left from my app (it looks
like when you start raw pipeline with some movie, without any
additional gtk elements).
Do you have any ideas??? Please help me.
Bart
