XmVaCreateSimplePulldownMenu - A RowColumn widget convenience
creation function
#include <Xm/RowColumn.h>
Widget XmVaCreateSimplePulldownMenu (parent, name,
post_from_button, callback, arg...)
Widget parent;
String name;
int post_from_button;
XtCallbackProc callback;
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 MenuPane and its button
children. The name of each button is button_n, where n is
an integer from 0 to one minus the number of buttons in
the menu. The name of each separator is separator_n, where
n is an integer from 0 to one minus the number of separators
in the menu. The name of each title is label_n, where
n is an integer from 0 to one minus the number of titles
in the menu. 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. Specifies the widget
ID of the parent of the MenuShell. Specifies the name
of the created widget. Specifies the CascadeButton or
CascadeButtonGadget in the parent to which the Pulldown
MenuPane is attached. The value is the integer n that corresponds
to the nth CascadeButton or CascadeButtonGadget
specified for the parent of the Pulldown MenuPane. A
Pulldown MenuPane 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. 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: This is followed by two additional
arguments. The set specifies one button in the PulldownMenu
and some of its resource values. The button created
is a CascadeButtonGadget. Following are the additional
two arguments, in this order: The label string, of type
XmString. The mnemonic, of type KeySym. This is followed
by four additional arguments. The set specifies one button
in the PulldownMenu and some of its resource values.
The button created is a PushButtonGadget. Following are
the additional four arguments, in this order: The label
string, of type XmString. The mnemonic, of type KeySym.
The accelerator, of type String. The accelerator text, of
type XmString. This is followed by four additional arguments.
The set specifies one button in the PulldownMenu
and some of its resource values. The button created is a
ToggleButtonGadget. Following are the additional four
arguments, in this order: The label string, of type
XmString. The mnemonic, of type KeySym. The accelerator,
of type String. The accelerator text, of type XmString.
This is followed by four additional arguments. The set
specifies one button in the PulldownMenu and some of its
resource values. The button created is a ToggleButtonGadget.
Following are the additional four arguments, in this
order: The label string, of type XmString. The mnemonic,
of type KeySym. The accelerator, of type String. The
accelerator text, of type XmString. This is followed by
one additional argument. The pair specifies a title
LabelGadget in the PulldownMenu. Following is the additional
argument: The title string, of type XmString. This
is followed by no additional arguments. It specifies one
separator in the PulldownMenu. This is followed by no
additional arguments. It specifies one separator in the
PulldownMenu. The separator type is XmDOUBLE_LINE. This
is followed by one additional argument, the value of the
resource, of type XtArgVal. The pair specifies a resource
and its value for the RowColumn widget. This is followed
by four additional arguments. The set specifies a
resource and its value for the RowColumn widget. A
resource type conversion is performed if necessary. Following
are the additional four arguments, in this order:
The resource name, of type String. The type of the
resource value supplied, of type String. The resource
value (or a pointer to the resource value, depending on
the type and size of the value), of type XtArgVal. The
size of the resource value in bytes, of type int. This is
followed by one additional argument of type XtVarArgsList.
This argument is a nested list of varargs returned by
XtVaCreateArgsList.
For more information on variable-length argument lists,
see the X Toolkit Intrinsics documentation.
A number of resources exist specifically for use with this
and other simple menu creation routines. For a complete
definition of RowColumn and its associated resources, see
XmRowColumn(3X).
Returns the RowColumn widget ID.
