DESCRIPTION

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

This routine creates a Popup menu pane and its button children. The name of each button is button_ n, where n is an integer from 0 (zero) 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 (zero) 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.

parent
Specifies the widget ID of the parent of the MenuShell

name
Specifies the name of the created widget

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. The following list describes the possible first arguments in each group of varargs.

XmVaCASCADEBUTTON
This is followed by two additional arguments. The set specifies one button in the PopupMenu and some of its resource values. The button created is a CascadeButtonGadget. Following are the additional two arguments, in order:

label
The label string, of type XmString

mnemonic
The mnemonic, of type KeySym

XmVaPUSHBUTTON
This is followed by four additional arguments. The set specifies one button in the PopupMenu and some of its resource values. The button created is a PushButtonGadget. Following are the additional four arguments, in order:

label
The label string, of type XmString

mnemonic
The mnemonic, of type KeySym

accelerator
The accelerator, of type String

accelerator_text
The accelerator text, of type XmString

XmVaRADIOBUTTON
This is followed by four additional arguments. The set specifies one button in the PopupMenu and some of its resource values. The button created is a ToggleButtonGadget. Following are the additional four arguments, in order:

label
The label string, of type XmString

mnemonic
The mnemonic, of type KeySym

accelerator
The accelerator, of type String

accelerator_text
The accelerator text, of type XmString

XmVaCHECKBUTTON
This is followed by four additional arguments. The set specifies one button in the PopupMenu and some of its resource values. The button created is a ToggleButtonGadget. Following are the additional four arguments, in order:

label
The label string, of type XmString

mnemonic
The mnemonic, of type KeySym

accelerator
The accelerator, of type String

accelerator_text
The accelerator text, of type XmString

XmVaTITLE
This is followed by one additional argument. The pair specifies a title LabelGadget in the PopupMenu. Following is the additional argument:

title
The title string, of type XmString

XmVaSEPARATOR
This is followed by no additional arguments. It specifies one separator in the PopupMenu.

XmVaDOUBLE_SEPARATOR
This is followed by no additional arguments. It specifies one separator in the PopupMenu. The separator type is XmDOUBLE_LINE.

resource_name
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.

XtVaTypedArg
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 order:

name
The resource name, of type String

type
The type of the resource value supplied, of type String

value
The resource value (or a pointer to the resource value, depending on the type and size of the value), of type XtArgVal

size
The size of the resource value in bytes, of type int

XtVaNestedList
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 (3).

RETURN

Returns the RowColumn widget ID.
