8.2.1 Loading Motif

On LispWorks platforms supporting pthreads, the supplied image contains the GTK GUI only, and therefore GTK is the default graphical library for applications. To build a Motif application on these platforms you need to include

in your delivery script.

You may wish to consider building a GTK version of your application too.

8.2.2 Motif on the target machine

A suitable version of the OpenMotif library must be installed on the target machine for your CAPI/Motif application to run. The version requirements are as for LispWorks itself, as mentioned in the LispWorks Release Notes and Installation Guide .

8.2.3 Fallback resources

If your CAPI/Motif application needs fallback resources then it should pass the :application-class and :fallback-resources arguments when calling capi:display and/or capi:convert-to-screen.

See capi:convert-to-screen in the CAPI User Guide and Reference Manual for a full description of these arguments.

You could use the LispWorks resources as a starting point when constructing your application's resources. You can see the LispWorks fallback resources (these are for application class Lispworks) as described under "Using X resources" in the CAPI User Guide and Reference Manual .

You can override the default resource name using the capi:element initarg :widget-name or the accessor (setf capi:element-widget-name).

8.2.4 X resource names use Lisp symbol names

The default color and other attributes for each CAPI pane on X11/Motif is computed as an X resource using the symbol name of the pane's class. Therefore obtaining the correct X resources depends on the application containing these symbol names.

Symbol names are removed at delivery level 5, but you can retain specific names in the delivered image by passing a list of the class names to deliver as the value of the keyword argument :keep-symbol-names.
