background

[montse <root pc46 fsc alcala es>]

hello every body:
i would like to change the background of a text widget.

i wrote down:

GdkColor color;
gdk_color_parse("black",&color);

text=gtk_text_new();

gdk_window_set_background(text->window, &color);

i also tried:
gdk_window_set_background(GTK_TEXT(text)->text_area, &color);

when i run the app i get the following message:

Gdk-CRITICAL **: file gdkwindow.c: line 1233
(gdk_window_set_background): assertion `window != NULL' failed.

what's wrong with that???
Is there any way of changing the background color of a text widget???
