Introduction TRUEDOX Menu Maker is designed for you to make your own Popup menu for non-mouse based applications. To create your own Popup menu, you must proceed the following steps: Step 1: Use Word processor or Editor which is compatible with DOC text file format (e.g. PE2, Professional Editor, WordStar, Word Perfect...) to create a menu source file, with an extension name of .DEF. Ex: File name: 123.DEF File name: DBASE.DEF Step 2: Use Menu Maker compiler file: MAKEMNU.EXE to compile your source file. [SYNTAX]: makemnu filename ENTER Ex: Makemnu 123 (ENTER) Makemnu DBASE (ENTER) Step 3: If there is no errors, your Popup menu is compiled and ready for use, the file automatically uses an extension name of .MNU. If errors happened, refer to the error message of chapter 4 to correct your source file, then repeat step 2. Ex: File name after compiler: 123.mnu File name after compiler: DBASE.mnu Step 4: Use menu maker execution file:MENU.EXE to execute your Popup menu. [SYNTAX]: menu filename ENTER Ex: Menu 123 (ENTER) Menu DBASE (ENTER) Step5: If you want to disable popup funtion, just type "menu off". Typing "menu on" enable popup function again. The menu source file can be developed easily by referring to the Menu language statement in Chapter II. However, it is suggested that user to read Chapter III for a brief tutorial(*) before go to Chapter II in details. * The source files(*.DEF) of the tutorial are included in the diskette. II. Menu language statements A. Commands TRUEDOX Menu Maker supports 13 commands, which assign different functions to generate Pop-up Menu to work with the mouse. They are described as follow: BEGIN: Defines function of mouse buttons, moving direction and speed sensitivity at the start of menu source file. This command is essential to start the source file. ASSIGN: Assigns new behavior to mouse actions which have been previously defined in the BEGIN statement. EXECUTE: Specifies a sequence of statements to be executed. MATCH: Specifies the action taken when a unique string of characters is displayed at a specified location on the screen. MENU: Begins a Menu subroutine. OPTION: Defines an item in a Menu subroutine and the action taken when the item is selected. MEND: Ends a Menu subroutine. POPUP: Begins a multi-column menu subroutine. TEXT: Defines the text for a Popup menu title or menu items. SELECT: Defines an item for the action taken when the item is selected in a Popup menu. PEND: Ends a Popup subroutine. TYPE: Sends characters and commands as if type from keyboard. NOTHING: Indicates that no action is taken. An alternative to the EXECUTE, TYPE, and MATCH statements. B. Statement Format Statement consists of 4 elements: Label, Command, Parameter and comments. The statement format is [label:] command parameters [;comments] ** Note: The elements in bracket "[ ]" are optional elements, which can be with or without in a statement. Label: A label is the name you assign to a statement, which allows the program to execute statements in a different order as they appear in source file. * Label must be followed by a colon(:) * At least one space between the colon and command. * Do not use command names or reserved words... BACKSPACE ENTER, ESC, TAB for labels. Parameters: Menu programming language uses three types of parameters: numeric parameters. string parameters. attribute parameters. * Numeric parameters: used for numeric data, such as screen coordinates or movement-sensitivity values for the mouse. * String parameters: string parameters specify text for menus or messages. * Display attribute parameters: A display attribute parameter specifies what color a menu or message box appears on the screen. Display attribute = Foreground colors + Background colors. Color Foreground Background Black 0 0 Blue 1 16 Green 2 32 Cyan (blue-green) 3 48 Red 4 64 Magenta 5 80 Brown 6 96 White 7 112 Gray 8 128 Light Blue 9 144 Light Green 10 160 Light Cyan 11 176 Light Red 12 192 Light Magenta 13 208 Yellow 14 224 White (high intensity) 15 240 Comments: Comments describe what a statement does, which have no effect when the statement is executed. There are five types of statements in the menu language: 1. Event statements: BEGIN, ASSIGN Define what action is taken when a mouse event occurs. 2. Menu statements: MENU, OPTION, MEND Create single-column menus. 3. Popup statements: POPUP, TEXT, SELECT, PEND Create multiple-column menus and message boxes. 4. Action statements: EXECUTE, TYPE, NOTHING Perform an action as a result of a mouse event, menu subroutine, or string match statement. 5. String match statement: MATCH Executes other statements depending on what is displayed on the screen. C. Command Description 1. BEGIN [SYNTAX] BEGIN [lfbtn], [rtbtn], [mdbtn], [lfmov], [rtmov], [upmov], [dnmov], [hsen], [vsen] Begin statement specifies 9 parameters(these parameters to be defined strictly in accordance with above sequence). Each parameter defines a statement to be executed when the user clicks a mouse button or moves the mouse. There are three types of parameters in the BEGIN statement: Button parameters: lfbtn Left button clicking rtbtn Right button clicking mdbtn Middle button clicking Define the action taken when one of mouse buttons are clicked. Movement parameters: lfmov Move leftword rtmov Move rightword upmov Move upword dnmov Move downward Define the action taken when the mouse is moved. Movement sensitivity parameters: hsen Horizontal movement sensitivity vsen vertical movement sensitivity Example: 旼컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴커 � BEGIN ent, esc,, lf, rt, up, dn � � � � lf: TYPE 0,75 ;simulate the left cursor key � � rt: TYPE 0,77 ;simulate the right cursor key � � up: TYPE 0,72 ;simulate the up cursor key � � dn: TYPE 0,80 ;simulate the down cursor key � � esc:TYPE ESC ;simulate the Esc key � � ent:TYPE ENTER ;simulate the enter key � 읕컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴켸 ent: Define left button statement. esc: Define right button statement. lf: Define move leftword statement. rt: Define move rightword statement. up: Define move upward statement. dn: Define move downward statement. The BEGIN statement in this example gives initial values for all parameters except "mdbtn", "hsen", and "vsen". Because "mdbtn" isn't specified, nothing happens when the user clicks middle button. Because no values are given for "hsen" and "vsen", the default values are used (8 and 16 mickeys, respectively) 2. ASSIGN [SYNTAX] label: ASSIGN [lfbtn], [rtbtn], [mdbtn], [lfmov], [rtmov], [upmov], [dnmov], [hsen], [vsen] Assign statement used to redefine one or more parameters given in the Begin statement or most recent Assign statement. If a parameter value isn't specified in an ASSIGN statement then this particular parameter value will remain the same as BEGIN statement or last ASSIGN statement. All parameters are defined in same format as Begin statement. All assign statements must be captioned with a label. Example: 旼컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴커 � BEGIN esc, ent, mml, lf, rt, up, dn � � . � � . � � . � � reassign: ASSIGN y, not,,,, not, not 16, 18 � 읕컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴켸 In this example, the BEGIN statement assigns the initial values of all button and movement parameters. Because no values are specified for the sensitivity parameters ("vsen" and "hsen"), the default values are used. The ASSIGN statement changes the values of the left button, right button, and up and down movement parameters. It also changes the value of "hsen" to 16 and the value of "vsen" to 18. Commas are used for the parameters whose values aren't changed. 3. EXECUTE [SYNTAX] ELabel: EXECUTE label [,label....] Execute command is used to define other statements to be executed. Statements within an EXECUTE statement are executed sequentially starting with the first statement. Parameters Elabel Name of the EXECUTE statement. All EXECUTE statements must be labeled. label Name of the statement to be executed. Example: exec: EXECUTE dir, s, c, ent 旼컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴� 쿭ir: TYPE "dir" � 쿞 : TYPE 32 ; Space Code � 쿎 : TYPE "c:" � 쿮nt: TYPE enter � 읕컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴� The EXECUTE statement labeled "exec" executes the statements labeled "dir", "s", "c", nd "ent". These statements simulate typing dir C: and pressing ENTER. 4. MATCH [SYNTAX] label: MATCH row, column, attribute, string, mlabel, nlabel MATCH command is used to define a specified string in a given screen location. If it is found then execute the match statement, else execute the nomatch statement. Row, column are used to describe the absolute screen coordinates. The starting coordinates for the screen are in the upper-left corner of screen (row=1, column=1). Parameters label Name of the MATCH statement. All MATCH statements must be labeled. row,column Used to specify the string coordinates on the screen. attribute Used to specify the attribute of string. This can be one of the symbolic values "normal", "bold", or "inverse", or a decimal value that denotes specific foreground and background colors.(refer to attribute parameters value) string This can be any string of up to 80 ASCII characters enclosed in double quotation marks (" "). mlabel if the string is matched, this label specifies statement will be executed. nlabel if the string is not matched, this label specifies statement will be executed. Example: 旼컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴커 쿍EGIN leftb � � � 쿹eftb: MATCH 5, 40, normal, "test", find, not-find � 쿯ind: TYPE "string match" � 쿻ot-find: TYPE "string not match" � 읕컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴켸 When user clicks the left mouse button, if there is a string "test", which on the screen at locate row=5, column=40, and attribute=normal, then will print out a message " string match", else print out "string not match". 5. MENU [SYNTAX] label: MENU "title", row, column, attribute OPTION "text", pointer . . . MEND MENU statement used to create single-column Popup menus. When this statement is active, there will be a single-column menu display on the screen, The user chooses items in the menu by moving mouse cursor to the desired item. then clicking left mouse button at once, the equivalent statement specified by pointer of OPTION statement will be executed. OPTION statement is used to define each menu item in the MENU statement. Parameter label Name of the Menu subroutine. All Menu subroutines must be labeled. title Text of the menu title, enclosed in double quotation marks (" "). row,column Used to specify the top-left corner of the menu appears. attribute Used to specify the attribute of menu displayed on the screen. text Legend text for the menu item. The legend text must be enclosed in double quotation marks (" "). pointer Label of the statement will be executed when user chooses the menu item. Example: 旼컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴커 쿺label: MENU "Display Directory", 5, 5, inverse � � OPTION " *.EXE ", Ex.1 � � OPTION " *.C ", Ex.2 � � OPTION " *.COM ", Ex.3 � � MEND � 쿐x.1 : TYPE "dir *.exe", enter � 쿐x.2 : TYPE "dir *.c", enter � 쿐x.3 : TYPE "dir *.com", enter � 읕컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴켸 (Screen coordinate) � 읕컴�> 旼Display Directory커 (5,5) � *.EXE � 쳐컴컴컴컴컴컴컴컴컴� � *.C � 쳐컴컴컴컴컴컴컴컴컴� � *.COM � 읕컴컴컴컴컴컴컴컴컴� This menu title is "Display Directory". The Top-left corner of the menu is in row 5, column 5, and an inverse screen attribute. The OPTION statements specify which statements are executed when the user chooses items from the menu. 6. POPUP [SYNTAX] label: POPUP row, column, attribute TEXT "string" . . SELECT srow, scolumn, width, pointer . . . PEND Popup statement is used to define multiple-column menu which are used in the same way as menu statement. Select command is used to define the selection area of items on the menu, and the statement which will be executed when the item is selected. Text command is used to define the menu title and the legend text for menu items. Parameter label Name of the Popup subroutine. All Popup statements must be labeled. row,column Used to specify the top-left corner of menu on the screen (the top left corner on the screen is row 1, column 1). attribute A value that specifies how the menu is displayed on the screen. This can be "normal", "bold", or "inverse", or a decimal value that specifies particular foreground and background colors. string Defines the Popup menu title or the legend text of a menu item. All text must be enclosed in double quotation marks (" "). You can use ASCII code to construct lines and boxes. All string defined by text statement must be equal length.
