XmVaCreateSimplePulldownMenu β€” a RowColumn widget convenience creation function. yes bestie, it literally builds you a whole pulldown menu ✨


🌸 SYNOPSIS 🌸

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

πŸ¦‹ DESCRIPTION πŸ¦‹

okay so. XmVaCreateSimplePulldownMenu makes you an instance of a RowColumn widget, type XmMENU_PULLDOWN, and hands you back the widget ID like it's your fave drink at the counter. πŸ₯€ This routine uses the ANSI C variable-length argument list (varargs) calling convention, iykyk.

This routine creates a Pulldown menu pane and its button children. Naming goes like this, no cap:

  • each button is named button_n, where n is an integer from 0 to the number of buttons in the menu minus 1
  • each separator is named separator_n, where n is an integer from 0 to the number of separators in the menu minus 1
  • each title is named label_n, where n is an integer from 0 (zero) to the number of titles in the menu minus 1

Buttons, separators, and titles get named and created in the order you specify them in the variable portion of the argument list. order matters, periodt.

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

  • parent β€” Specifies the widget ID of the parent of the MenuShell.
  • name β€” Specifies the name of the created widget.
  • post_from_button β€” 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). πŸ’…
  • callback β€” 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. πŸ‘‘

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. do not forget the NULL, bestie, that's the whole vibe check right there 😭 Following are the possible first arguments in each group of varargs:

πŸ“ the varargs groups πŸ“

  • XmVaCASCADEBUTTON β€” 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 order:
    • label β€” The label string, of type XmString
    • mnemonic β€” The mnemonic, of type KeySym
  • XmVaPUSHBUTTON β€” 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 order:
    • label β€” The label string, of type XmString
    • mnemonic β€” The mnemonic, of type KeySym
    • accelerator β€” The accelerator, of type String
    • accelerator_text β€” The accelerator text, of type XmString
  • XmVaRADIOBUTTON β€” 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 order:
    • label β€” The label string, of type XmString
    • mnemonic β€” The mnemonic, of type KeySym
    • accelerator β€” The accelerator, of type String
    • accelerator_text β€” The accelerator text, of type XmString
  • XmVaCHECKBUTTON β€” 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 order:
    • label β€” The label string, of type XmString.
    • mnemonic β€” The mnemonic, of type KeySym
    • accelerator β€” The accelerator, of type String
    • accelerator_text β€” The accelerator text, of type XmString
  • XmVaTITLE β€” This is followed by one additional argument. The pair specifies a title LabelGadget in the PulldownMenu. Following is the additional argument:
    • title β€” The title string, of type XmString
  • XmVaSEPARATOR β€” This is followed by no additional arguments. It specifies one separator in the PulldownMenu.
  • XmVaDOUBLE_SEPARATOR β€” This is followed by no additional arguments. It specifies one separator in the PulldownMenu. The separator type is XmDOUBLE_LINE. ✌️
  • resource_name β€” 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 β€” 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 β€” The resource name, of type String.
    • type β€” The type of the resource value supplied, of type String.
    • value β€” The resource value (or a pointer to the resource value, depending on the type and size of the value), of type XtArgVal.
    • size β€” The size of the resource value in bytes, of type int.
  • XtVaNestedList β€” This is followed by one additional argument of type XtVarArgsList. This argument is a nested list of varargs returned by XtVaCreateArgsList.

and that's the whole page, bestie πŸ’– this one lives in the library call section, filed under XmVaCreateS...ulldownMenu(library call) β€” yes the title got abbreviated on both ends, the header up top and the footer at the bottom, but it's still our girl XmVaCreateSimplePulldownMenu. go build something iconic with it πŸ‘‘βœ¨πŸ’
