Re: Cannot set foreground colour of Entry widget

[Edoardo Vigoni <vigoni@aero.polimi.it>]

Try this code. I use this in gtk+-1.2 and work well. colore1 is the text color and colore2 the background color, I set also the font of the text, the widget is the entry:

you can call in this way:
color_set_display(GTK_WIDGET(entry), "pale green", "black");

void color_set_display(GtkWidget *widget, gchar *colore1, gchar *colore2)
{
GtkStyle    *style;

GdkColormap *cmap;
GdkColor    color;
GdkFont     *font;


    >

    font=gdk_font_load("-schumacher-clean-bold-r-normal-*-14-*-*-*-*-*-iso646.1991-*");

    if (font != NULL) style->font=font;

    cmap = gdk_colormap_get_system();
    gdk_color_parse(colore1, &color);

    if(!gdk_colormap_alloc_color(cmap, &color, TRUE, TRUE))
    	{
    	g_error("couldn't allocate colour");
    	}

    style->fg[GTK_STATE_NORMAL]=color;

    gdk_color_parse(colore2, &color);

   if(!gdk_colormap_alloc_color(cmap, &color, TRUE, TRUE))
    	{
    	g_error("couldn't allocate colour");
    	}

    style->base[widget->state]=color;

    gtk_widget_set_style(widget, style);

}
