Hi c_c,

thanks for bringing another superb app to the neo!

I'm not an X11 expert, just trying to answer some of your questions
here... If I babble nonsense, please correct me.

The problem is that your windows will end up stacked ontop of each other, and
here is why:

In X11, you do normally not position your windows on the screen. You have a
separate process, the "window manager" or WM, that takes care of this task.
That way, the user can finetune the behaviour of this desktop in one place,
instead of having to tune each and every app separately.

When you create a new window, the window manager will be consulted and will
come up with the best position/size for that new window. It will also draw some
decorations around it (border, titlebar, icons), so you have a consistent look.

On your desktop, where you have plenty of space, the best policy for the WM
is to arrange windows such that they don't overlap too much. On the neo
however, where screen space is a premium, the default strategy is to maximize
and center each window and forget about the borders, titlebars and stuff...

Both of your windows will simply be maximized and the one you create later will
end up on top of the stack. That way, you loose your controls.

> 2. The video playing window is centered on the screen. Is there a way I can

There is a way to have absolute control over the window by overriding the
window manager:

   EAPI void         ecore_evas_override_set(Ecore_Evas* ee, Evas_Bool

or in elementary:

   EAPI void         elm_win_override_set(Evas_Object *obj, Evas_Bool override);

If you do this, the WM won't touch your window, and you will have to position
and size it yourself. Be aware though, that you also will have to take into
account any bars (taskbar / titlebar etc...) as you now work with raw
screen coords.
Usually, you have a normal window that is placed in the usual way by the wm.
You learn it's size and raw coordinates on screen and place the
overridden window
such that it fits inside.

> 3. Is there a way to embed a window in the main window of an elementary app?

There is the elementary inwin. But this is not a X11 window with it's own wid.
As far as I know, there is currently no elementary widget for this.

> 4. As far as I can see, mplayer uses the entire window (whose handle is

Not that I know. But what you can do, is to create a second X11 window, with
the override bit set. Position it manually, based on the co-ordinates of your
main window, and hand its wid to mplayer. the WM won't add any decoration
to it, thanks to the override bit, and mplayer will fill it with the
movie, so the
second window should not be recognizable as a window.

You should be able to get the position and sitze of your main elm_win using
something like this:

   EAPI void              evas_object_geometry_get          (const
Evas_Object *obj, Evas_Coord *x, Evas_Coord *y, Evas_Coord *w,
Evas_Coord *h);

Then you can simply create a second elm_win with the right coordinates, and
set the override bit _before_ you make the window visible.

Hope this helps...
