Re: Background color problem

[Vlad Volodin <vest 84 gmail com>]

No guys, that doesn't help.
Well my code is the next one:
static GObject* quod_board_widget_constructor(GType type, guint
n_construct_properties, GObjectConstructParam *construct_properties)
{
    GObject *obj;
    QuodBoardWidgetClass *klass;
    GObjectClass *parent_class;
    QuodBoardWidget *self;
    g_debug("quod_board_widget_constructor");

   self = QUOD_BOARD_WIDGET(obj);
    {
        GError* err = NULL;

        gtk_widget_realize(GTK_WIDGET(self));

        GtkStyle* default_style = gtk_widget_get_style (GTK_WIDGET(self));
        GdkColor* bg = &default_style->bg[GTK_STATE_NORMAL];
        ClutterColor     stage_color = { bg->red / 0xFF, bg->green /
0xFF, bg->blue / 0xFF, 0xF0 };

        ClutterActor    *stage = gtk_clutter_embed_get_stage
(GTK_CLUTTER_EMBED (self));
        g_debug("quod_board_widget_constructor: %x %x %x %x", bg->red,
bg->green, bg->blue, bg->pixel);

        clutter_stage_set_color (CLUTTER_STAGE (stage), &stage_color);
    }
    return obj;
}

static GObject* quod_main_window_constructor(GType type, guint
n_construct_properties, GObjectConstructParam *construct_properties)
{
    GObject *obj;
    QuodMainWindowClass *klass;
    GObjectClass *parent_class;
    QuodMainWindow *self;
    g_debug("quod_main_window_constructor");
    klass = QUOD_MAIN_WINDOW_CLASS(g_type_class_peek(QUOD_TYPE_MAIN_WINDOW));
    parent_class = G_OBJECT_CLASS(g_type_class_peek_parent(klass));
    obj = parent_class->constructor(type, n_construct_properties,
construct_properties);
    self = QUOD_MAIN_WINDOW(obj);
    {
        GError* err = NULL;


        gtk_window_set_title((GtkWindow*) self, "Gnome Quod");

        gtk_window_set_default_size((GtkWindow*) self,
MAIN_WINDOW_DEFAULT_WIDTH, MAIN_WINDOW_DEFAULT_HEIGHT);
        g_signal_connect((GtkObject*) self, "destroy", (GCallback)
_gtk_main_quit_gtk_object_destroy, NULL);

        gtk_window_set_icon_from_file((GtkWindow*) self, GNOME_ICONDIR
"/quod.png", &err);

        // Create all used widgets and attach possible signals
        quod_main_window_create_widgets(self);

        GtkStyle* default_style = gtk_widget_get_style (GTK_WIDGET(self));
        GdkColor* bg = &default_style->bg[GTK_STATE_NORMAL];
        g_debug("quod_main_window_constructor (before show):%x %x %x
%x", bg->red, bg->green, bg->blue, bg->pixel);

        gtk_widget_show_all((GtkWidget*) self);

        default_style = gtk_widget_get_style (GTK_WIDGET(self));
        bg = &default_style->bg[GTK_STATE_NORMAL];
        g_debug("quod_main_window_constructor (after show):%x %x %x
%x", bg->red, bg->green, bg->blue, bg->pixel);
    }
    return obj;
}

here you can see the gray box, it is colored from ClutterColor stage_color.

I wish, you can help me with the next question: When is GtkStyle
(compare before show and after show) applied to my windows/ widgets
etc. I can't get correct (blue, as in screen) colors, instead of them
I got gray: #dcdad5. I don't have such colors in my themas. Are they
default. (they are equal to gtk_wiget_get_default_style)

Thank you all again :)
