Once a menu has been posted (displayed), you should funnel
input events to it through <STRONG>menu_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><A HREF="curs_getch.3x.html">wgetch(3x)</A></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
+ checked according to the program's locale settings.
- - 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 menu driver requests are as follows:
If the second argument is one of the above pre-defined
requests, the corresponding action is performed.

+</PRE><H3><a name="h3-MOUSE-HANDLING">MOUSE HANDLING</a></H3><PRE>
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
If you click above the display region of the menu:
- a REQ_SCR_ULINE is generated for a single click,
+ <STRONG>o</STRONG> a REQ_SCR_ULINE is generated for a single click,
- a REQ_SCR_UPAGE is generated for a double-click and
+ <STRONG>o</STRONG> a REQ_SCR_UPAGE is generated for a double-click and
- a REQ_FIRST_ITEM is generated for a triple-click.
+ <STRONG>o</STRONG> a REQ_FIRST_ITEM is generated for a triple-click.
If you click below the display region of the menu:
- a REQ_SCR_DLINE is generated for a single click,
+ <STRONG>o</STRONG> a REQ_SCR_DLINE is generated for a single click,
- a REQ_SCR_DPAGE is generated for a double-click and
+ <STRONG>o</STRONG> a REQ_SCR_DPAGE is generated for a double-click and
- a REQ_LAST_ITEM is generated for a triple-click.
+ <STRONG>o</STRONG> a REQ_LAST_ITEM is generated for a triple-click.
If you click at an item inside the display area of the
menu:
- - the menu cursor is positioned to that item.
+ <STRONG>o</STRONG> the menu cursor is positioned to that item.
- - If you double-click an item a REQ_TOGGLE_ITEM is
- generated and <STRONG>E_UNKNOWN_COMMAND</STRONG> is returned.
- This return value makes sense, because a double
- click usually means that an item-specific action
- should be returned. It is exactly the purpose
- of this return value to signal that an applica-
- tion specific command should be executed.
+ <STRONG>o</STRONG> If you double-click an item a REQ_TOGGLE_ITEM is gen-
+ erated and <STRONG>E_UNKNOWN_COMMAND</STRONG> is returned. This return
+ value makes sense, because a double click usually
+ means that an item-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>menu_driver</STRONG> returns the result of this request.
+ <STRONG>o</STRONG> If a translation into a request was done, <STRONG>menu_driver</STRONG>
+ returns the result of this request.
If you clicked outside the user window or the mouse event
could not be translated into a menu request an
<STRONG>E_REQUEST_DENIED</STRONG> is returned.

If the second argument is neither printable nor one of the
above pre-defined menu requests or KEY_MOUSE, the drive
assumes it is an application-specific command and returns
these pre-defined requests.
