GTK+ provides resource file mechanism for configuring various
aspects of the operation of a program at runtime. Most of the time,
though, resource files are used for changing styles of the
application's widgets.
Application should load its resource file using rc_parse() function:
<?php
gtk::rc_parse(dirname($argv[0]).'/myapp.rc');
?>
This will load myapp.rc file loaded in the same directory as the application.
Syntax
A resource file defines a number of styles and attaches them to
particular widgets. The attachment is done by the widget,
widget_class, and class declarations. As an example of such a
statement:
widget "mywindow.*.GtkEntry" style "my-entry-class"
This attaches the style "my-entry-class" to all widgets whose widget
class matches the pattern "mywindow.*.GtkEntry". The patterns are
given in the standard shell glob syntax. The "?" wildcard
matches any character, while "*" matches zero or more of any
character. The three types of matching are against the widget path,
the class path and the class heirarchy. Both the widget and the
class paths consists of a "." separated list of all the parents of
the widget and the widget itself from outermost to innermost. The
difference is that in the widget path, the name assigned by
GtkWiget::set_name() is used if present, otherwise the class name of
the widget, while for the widget path, the class name is always
used.
