Re: Color in GtkText

[sml13 cornell edu]

I had a similar problem that I posted to GTK-list a while back, and 
no-one really gave me a satisfactory response other than "you should use 
themes to do this."  Well, no, I want it to be a static property of 
the app so themes aren't an option.  What I wanted to do is set 
the color of the text and background of a gtk_entry by doing (I thought):

    time = gtk_entry_new ();
    style = gtk_style_new ();
    style->font = gdk_font_load 
("-adobe-helvetica-bold-r-normal-*-*-240-*-*-p-*-iso8859-1");
    style->text[GTK_STATE_NORMAL].red = 0;
    style->text[GTK_STATE_NORMAL].green = 1;
    style->text[GTK_STATE_NORMAL].blue = 0;
    style->bg[GTK_STATE_NORMAL] = style->black;
    gtk_widget_set_style (time, style);

You see, I want my time display to have alien green digits (this is for a 
CD Player) on a black background...but this doesn't work!  I DO NOT want 
this to vary with the themes, so theming to this isn't an option.  I want 
to know how to do this (and, generallly, set the attributs of any widget 
like this) PROGRAMMATICALLY.  Any ideas?
