Gtk Modules

Programs that make use of GAIL (the accessibility implementation library for GTK widgets) are written as GTK modules. GTK modules are loaded into the program space if the GTK_MODULES environment variable specifies the module library name(s). If there are multiple module libraries, separate them with colons. For example:

setenv GTK_MODULES "libgail:libtestprops"

All GTK modules have a gtk_module_init() function.
