RE: GTK+ 2.2.0: gtk_window_move(window, 0, 0)

[martyn 2 russell bt com]

I have recently been experiencing these problems.  With ver 2.x.x (2.0.6 for
RedHat and 2.2.0 for Windows) I have noticed, if I use
gdk_window_move(GDK_WINDOW(window),0,0) it will put the window (from the top
left start of the decorations) in 0,0.  The same code on windows, puts the
client part of the window (i.e. not the decorations) at 0,0.  This is
annoying because the window title bar is then off the screen.

I have made a small function to get round this (below):

gboolean set_positions_callibration()
{
    gint offset_x = 0;
    gint offset_y = 0;

    gdk_window_move(GDK_WINDOW(window),0,0);  
    gdk_window_get_root_origin(GDK_WINDOW(window), &offset_x, &offset_y); 

    pos_offset_x = abs(offset_x);
    pos_offset_y = abs(offset_y);

    return TRUE;
}

and when I move the window, I use:

    gdk_window_move(GDK_WINDOW(window), (pos_offset_x + left), (pos_offset_y
+ top));


this (the callibration function) is only used on windows!  Of all the
gdk_window_ functions, gdk_window_get_root_origin(...) was the only function
that told me -5, -24 when calling it on the window I was interested in, all
the rest returned -1, -1.  I tried the following:

    gdk_window_get_deskrelative_origin(GDK_WINDOW(window), &x, &y); 
    g_message("desk orig pos= x:%d, y:%d", x,y);

    gdk_window_get_origin(GDK_WINDOW(window), &x, &y); 
    g_message("orig pos= x:%d, y:%d", x,y);

    gdk_window_get_root_origin(GDK_WINDOW(window), &x, &y); 
    g_message("root orig pos= x:%d, y:%d", x,y);

    gdk_window_get_position(GDK_WINDOW(window), &x, &y); 
    g_message("pos= x:%d, y:%d", x,y);

    gdk_window_get_geometry(window, &x, &y, &w, &h, &d);
    g_message("geom= x:%d, y:%d, w:%d, h:%d, d:%d", x,y,w,h,d);
