The goal of this module it look at all available GUI Bindings and determine which ones are installed and then choose one to run with.

If you want to run with tk explicitly then set the following environment variable:

    export locana_binding=tk

If you want to run with mswin32 explicitly then set the following environment variable:

    export locana_binding=mswin32

Status:

• Works with mswin32, tk.

To do:

History:

• 9/28/2002 - Changed mswin32 to check for Locana_gui_mswin32.DLL instead of locana_gui_mswin_ext.so. Disable the check to see if the TCL interpreter actually works.
• 3/2/2002 - Added support for an environment variable to specify the GUI Binding you want run with. This is useful if you have more than one GUI tool kit installed.
• 1/30/2002 - First official release.
• 1/20/2002 - Started

This method returns true if the mswin32 binding is available, otherwise returns false.

This method returns true if the Tk binding is available, otherwise returns false.

This method returns true if the XLib binding is available, otherwise returns false.
