INSERTMENUQQ (W*32, W*64)

QuickWin Function: Inserts a menu item into a QuickWin menu and registers its callback routine.

Module

USE IFQWIN

Syntax

result = INSERTMENUQQ (menuID,itemID,flag,text,routine)

menuID

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

itemID

(Input) INTEGER(4). Identifies the position in the menu where the item is inserted, starting with 0 as the top menu item.

flag

(Input) INTEGER(4). Constant indicating the menu state. Flags can be combined with an inclusive OR (see 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) EXERNAL. Callback subroutine that is called if the menu item is selected. All routines ake 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 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(4). The result is .TRUE. if successful; otherwise, .FALSE.

Menus and menu items must be defined in order from left to right and top to bottom. For example, INSERTMENUQQ fails if you try to insert menu item 7 when 5 and 6 are not defined yet. For a top-level menu item, the callback routine is ignored if there are subitems under it.

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 INSERTMENUQQ 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+Rin the example) as an alternative to selecting the item with the mouse.
