input events to it through <STRONG>form_driver</STRONG>. This routine has
three major input cases:
- - The input is a form navigation request. Navigation
- request codes are constants defined in <STRONG><form.h></STRONG>, which
- are distinct from the key- and character codes returned
- by <STRONG>wgetch</STRONG>.
+ <STRONG>o</STRONG> The input is a form navigation request. Navigation
+ request codes are constants defined in <STRONG><form.h></STRONG>, which
+ are distinct from the key- and character codes
+ returned by <STRONG>wgetch</STRONG>.
- - The input is a printable character. Printable charac-
- ters (which must be positive, less than 256) are
- checked according to the program's locale settings.
+ <STRONG>o</STRONG> The input is a printable character. Printable charac-
+ ters (which must be positive, less than 256) are

- - The input is the KEY_MOUSE special key associated with
- an mouse event.
+ <STRONG>o</STRONG> The input is the KEY_MOUSE special key associated with
+ an mouse event.
The form driver requests are as follows:
If the second argument is the KEY_MOUSE special key, the
associated mouse event is translated into one of the above
pre-defined requests. Currently only clicks in the user
- window (e.g. inside the form display area or the decora-
+ window (e.g., inside the form display area or the decora-
tion window) are handled.
If you click above the display region of the form:
- a REQ_PREV_FIELD is generated for a single click,
+ a REQ_PREV_FIELD is generated for a single click,
- a REQ_PREV_PAGE is generated for a double-click and
+ a REQ_PREV_PAGE is generated for a double-click and
- a REQ_FIRST_FIELD is generated for a triple-click.
+ a REQ_FIRST_FIELD is generated for a triple-click.
If you click below the display region of the form:
- a REQ_NEXT_FIELD is generated for a single click,
+ a REQ_NEXT_FIELD is generated for a single click,
- a REQ_NEXT_PAGE is generated for a double-click and
+ a REQ_NEXT_PAGE is generated for a double-click and
- a REQ_LAST_FIELD is generated for a triple-click.
+ a REQ_LAST_FIELD is generated for a triple-click.
If you click at an field inside the display area of the
form:
- - the form cursor is positioned to that field.
+ <STRONG>o</STRONG> the form cursor is positioned to that field.
- - If you double-click a field, the form cursor is
- positioned to that field and <STRONG>E_UNKNOWN_COMMAND</STRONG>
- is returned. This return value makes sense,
- because a double click usually means that an
- field-specific action should be returned. It is
- exactly the purpose of this return value to sig-
- nal that an application specific command should
- be executed.

- - If a translation into a request was done,
- <STRONG>form_driver</STRONG> returns the result of this request.
