Re: Color in GtkText

[sml13 cornell edu]

I tried what you recommended, Nigel.  And (like the last time) the only 
thing that it set right was the Font.  Nothing else.  The text background 
is still white and the numbers are still black.  Do I have to get at the 
GtkTextWidget WITHIN the GtkEntry to set this stuff?  That seems kind of 
ugly, but I suppose it's possible.  Then I have to know about GtkEntry 
internals just to set a few properties of it!  This can't be a Good Thing 
(tm).  Any further advice would be greatly appreciated.  Here is the 
relevant portion of the code that I am using verbatim:

    GdkColor c;
    GtkStyle *style;
    GtkWidget *time;

	[snip]

    time = gtk_entry_new ();
    
    /* allocate a new color */
    c.red = 0;
    c.green = 0xffff;
    c.blue = 0;
    gdk_color_alloc (gtk_widget_get_colormap (time), &c);

    /* get a copy of the current widget style */
    style = gtk_style_copy (gtk_widget_get_style (time));

    /* set the text color */
    style->text[GTK_STATE_NORMAL] = c;
    
    /* throw away the old font */
    gdk_font_unref (style->font);

    /* set the new font */
    style->font = gdk_font_load 
("-adobe-helvetica-bold-r-normal-*-*-240-*-*-p-*-iso8859-1");
    
    /* set the background to be black */
    c.red = 0x000000;
    c.green = 0x000000;
    c.blue = 0x000000;
    gdk_color_alloc (gtk_widget_get_colormap (time), &c);
    style->bg[GTK_STATE_NORMAL] = c;

    gtk_widget_set_style (time, style);
    gtk_entry_set_text (GTK_ENTRY (time), "[0] 00:00.00");
