XmVaCreate...lldownMenu(3) Library Functions Manual XmVaCreate...lldownMenu(3) NAME XmVaCreateSimplePulldownMenu -- A RowColumn widget convenience creation function 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 Cas- cadeButtonGadget 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 Cascade- Button 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 Cas- cadeButtons and CascadeButtonGadgets are counted in determin- ing the integer n. The first CascadeButton or CascadeButton- Gadget 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 CascadeButton- Gadget or a PushButtonGadget, the callback is added as the button's XmNactivateCallback, and it is called when the but- ton 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 argu- ments. 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: XmVaCASCADEBUTTON This is followed by two additional arguments. The set speci- fies one button in the PulldownMenu and some of its resource values. The button created is a CascadeButtonGadget. Follow- ing 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 speci- fies one button in the PulldownMenu 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 speci- fies one button in the PulldownMenu 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 speci- fies one button in the PulldownMenu 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 speci- fies a title LabelGadget in the PulldownMenu. 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 PulldownMenu. XmVaDOUBLE_SEPARATOR This is followed by no additional arguments. It specifies one separator in the PulldownMenu. The separator type is XmDOU- BLE_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 speci- fies a resource and its value for the RowColumn widget. A re- source 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 re- turned 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.
