NAME

       XmVaCreateSimplePulldownMenu   —   A   RowColumn   widget  convenience  creation  function
       "XmVaCreateSimplePulldown\%Menu" "creation functions" "XmVaCreateSimplePulldown\%Menu"

SYNOPSIS

       #include <Xm/RowColumn.h>
       Widget XmVaCreateSimplePulldownMenu(
       Widget parent,
       String name,
       int post_from_button,
       XtCallbackProc callback);

DESCRIPTION

       XmVaCreateSimplePulldownMenu  creates  an  instance  of  a  RowColumn   widget   of   type
       XmMENU_PULLDOWN  and  returns  the  associated  widget  ID.   This routine uses the ANSI C
       variable-length argument list (varargs) calling convention.

       This routine creates a Pulldown menu pane and its  button  children.   The  name  of  each
       button  is  button_n,  where  n  is an integer from 0 to the number of buttons in the menu
       minus 1.  The name of each separator is separator_n, where n is an integer from 0  to  the
       number  of  separators in the menu minus 1.  The name of each title is label_n, where n is
       an integer from 0 (zero)  to  the  number  of  titles  in  the  menu  minus  1.   Buttons,
       separators,  and  titles are named and created in the order in which they are specified in
       the variable portion of the argument list.

       This routine also attaches the PulldownMenu to a CascadeButton or  CascadeButtonGadget  in
       the parent.  The PulldownMenu is then posted from this button.

       parent    Specifies the widget ID of the parent of the MenuShell.

       name      Specifies the name of the created widget.

       post_from_button
                 Specifies  the  CascadeButton  or CascadeButtonGadget in the parent to which the
                 Pulldown menu pane is attached.  The value is the integer n that corresponds  to
                 the  nth  CascadeButton  or  CascadeButtonGadget specified for the parent of the
                 Pulldown  menu  pane.   A  Pulldown  menu  pane  can  be  attached  only  to   a
                 CascadeButton    or    CascadeButtonGadget,    and   only   CascadeButtons   and
                 CascadeButtonGadgets are counted  in  determining  the  integer  n.   The  first
                 CascadeButton or CascadeButtonGadget is number 0 (zero).

       callback  Specifies  a  callback procedure to be called when a button is activated or when
                 its value changes.  This  callback  function  is  added  to  each  button  after
                 creation.   For  a  CascadeButtonGadget  or  a PushButtonGadget, the callback is
                 added as the button's XmNactivateCallback, and it is called when the  button  is
                 activated.   For  a  ToggleButtonGadget,  the  callback is added as the button's
                 XmNvalueChangedCallback, and it is called when the button's value changes.   The
                 button number is returned in the client_data field.

       The  variable  portion  of  the  argument list consists of groups of arguments.  The first
       argument in each group is a constant or a string and determines which arguments follow  in
       that group.  The last argument in the list must be NULL.  Following are the possible first
       arguments in each group of varargs:
