APPENDMENUQQ (W*S)

QuickWin Function: Appends a menu item to the end of a menu and registers its callback subroutine.

Module

USE IFQWIN

result = APPENDMENUQQ (menuID, flags, text,routine)

menuID

(Input) INTEGER(4). Identifies the menu to which the item is appended, starting with 1 as the leftmost menu.

flags

(Input) INTEGER(4). Constant indicating the menu state. Flags can be combined with an inclusive OR (see the Results section below). The following constants are available:

  • $MENUGRAYED - Disables and grays out the menu item.

  • $MENUDISABLED - Disables but does not gray out the menu item.

  • $MENUENABLED - Enables the menu item.

  • $MENUSEPARATOR - Draws a separator bar.

  • $MENUCHECKED - Puts a check by the menu item.

  • $MENUUNCHECKED - Removes the check by the menu item.

text

(Input) Character*(*). Menu item name. Must be a null-terminated C string, for example, 'WORDS OF TEXT'C.

routine

(Input) EXTERNAL. Callback subroutine that is called if the menu item is selected. All routines take a single LOGICAL parameter that indicates whether the menu item is checked or not. You can assign the following predefined routines to menus:

  • WINPRINT - Prints the program.

  • WINSAVE - Saves the program.

  • WINEXIT - Terminates the program.

  • WINSELECTTEXT - Selects text from the current window.

  • WINSELECTGRAPHICS - Selects graphics from the current window.

  • WINSELECTALL - Selects the entire contents of the current window.

  • WININPUT - Brings to the top the child window requesting input and makes it the current window.

  • WINCOPY - Copies the selected text and/or graphics from the current window to the Clipboard.

  • WINPASTE - Allows the user to paste Clipboard contents (text only) to the current text window of the active window during a READ.

  • WINCLEARPASTE - Clears the paste buffer.

  • WINSIZETOFIT - Sizes output to fit window.

  • WINFULLSCREEN - Displays output in full screen.

  • WINSTATE - Toggles between pause and resume states of text output.

  • WINCASCADE - Cascades active windows.

  • WINTILE - Tiles active windows.

  • WINARRANGE - Arranges icons.

  • WINSTATUS - Enables a status bar.

  • WININDEX - Displays the index for QuickWin help.

  • WINUSING - Displays information on how to use Help.

  • WINABOUT - Displays information about the current QuickWin application.

  • NUL - No callback routine.

Results

The result type is logical. It is .TRUE. if successful; otherwise, .FALSE..

You do not need to specify a menu item number, because APPENDMENUQQ always adds the new item to the bottom of the menu list. If there is no item yet for a menu, your appended item is treated as the top-level menu item (shown on the menu bar), and text becomes the menu title. APPENDMENUQQ ignores the callback routine for a top-level menu item if there are any other menu items in the menu. In this case, you can set routine to NUL.

If you want to insert a menu item into a menu rather than append to the bottom of the menu list, use INSERTMENUQQ.

The constants available for flags can be combined with an inclusive OR where reasonable, for example $MENUCHECKED .OR. $MENUENABLED. Some combinations do not make sense, such as $MENUENABLED and $MENUDISABLED, and lead to undefined behavior.

You can create quick-access keys in the text strings you pass to APPENDMENUQQ as text by placing an ampersand (&) before the letter you want underlined. For example, to add a Print menu item with the r underlined, text should be "P&rint". Quick-access keys allow users of your program to activate that menu item with the key combination ALT+QUICK-ACCESS-KEY (ALT+R in the example) as an alternative to selecting the item with the mouse.

Example

      USE IFQWIN
      LOGICAL(4) result
      CHARACTER(25) str
      ...
! Append two items to the bottom of the first (FILE) menu
      str    = '&Add to File Menu'C ! 'A' is a quick-access key
      result = APPENDMENUQQ(1, $MENUENABLED, str, WINSTATUS)
      str    = 'Menu Item &2b'C ! '2' is a quick-access key
      result = APPENDMENUQQ(1, $MENUENABLED, str, WINCASCADE)
! Append an item to the bottom of the second (EDIT) menu
      str    = 'Add to Second &Menu'C ! 'M' is a quick-access key
      result = APPENDMENUQQ(2, $MENUENABLED, str, WINTILE)
