Resource files
**************

Resource files let you parametrize aspects of the widgets in a GtkAda
application without having to recompile it.

A resource file needs to be loaded (*Gtk.Rc.Parse*) *before* setting
the corresponding window.

In this file, it is possible to specify visual characteristics of
widgets, such as their colors and fonts.  Under X, the *xfontsel*
command allows you to easily select a font.  The FontSelection widget
is also a simple way to select fonts.

Here is an example of a resource file:

   # application.rc
   #
   # resource file for "Application"

   # Buttons style
   style "button"
   {
     # BackGround Colors
     #                  Red  Green  Blue
     bg[PRELIGHT] = { 0.0,  0.75, 0.0 } # Green when the mouse is on
                                        # the button
     bg[ACTIVE]   = { 0.75, 0.0,  0.0 } # Red on click
     # ForeGround Colors
     #                  Red  Green  Blue
     fg[PRELIGHT] = { 1.0,  1.0,  1.0 } # White when the mouse is on
                                        # the button
     fg[ACTIVE]   = { 1.0,  1.0,  1.0 } # White on click
   }

   # All the buttons will have the style "button"
   widget_class "*GtkButton*" style "button"

   # Text style
   style "text"
   {
     font = "-adobe-courier-medium-r-normal-*-15-*-*-*-*-*-*-*"
     text[NORMAL] = { 0.0, 0.0, 0.0 } # black
     fg[NORMAL]   = { 0.0, 0.0, 0.0 } # black
     base[NORMAL] = { 1.0, 1.0, 1.0 } # white : background color
   }

   # All Gtk_Text will have the "text" style
   widget_class "*GtkText" style "text"
