- The Grip widget provides a small rectangular region in which user input
- events (such as ButtonPress or ButtonRelease) may be handled. The most
- common use for the Grip widget is as an attachment point for visually
- repositioning an object, such as the pane border in a Paned widget.

- Grip Actions
- .IN "Grip widget" "actions"
- .LP
- The Grip widget does not declare any default event translation bindings,
- but it does declare a single action routine named \fBGripAction\fP. The
- .IN "Grip widget" "GripAction routine"
- client specifies an arbitrary event translation table, optionally giving
- parameters to the \fBGripAction\fP routine.
- .LP
- The \fBGripAction\fP routine executes the callbacks on the
- \fBcallback\fP list, passing as \fIcall_data\fP a pointer to a
- \fBXawGripCallData\fP structure, defined in the Grip widget's application
- header file.

- In this structure, the \fIevent\fP is a pointer to the input event that
- triggered the action. \fIparams\fP and \fInum_params\fP give the string
- parameters specified in the translation table for the particular event
- binding.
