PRB: Menus Behave Differently in OS 8

• Microsoft Visual FoxPro for Macintosh, version 3.0b
• Microsoft FoxPro for Macintosh, version 2.6a

SYMPTOMS

Menu pads, also known as Menu titles, that do not have a submenu associated with them, will not work with a single mouse click when used in FoxPro with Macintosh OS 8. These menu pads require a double-click.

CAUSE

This behavior is caused by a change to the Macintosh operating system with OS 8. The system now has sticky menus that stay down when a menu title is clicked. Previously, the menu would not stay down when the title was clicked.

RESOLUTION

Use submenus with all menu titles (menu pads).

STATUS

Microsoft is researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

MORE INFORMATION

The DEFINE PAD command is used to create menu titles on menu bars. If there is not a menu associated with the menu title, the ON SELECTION PAD command is used to specify a command that executes when the menu title is selected. Alternatively, if a menu title has a menu associated with it, the ON PAD command is used to activate the popup and its bars that make up the menu. Both menu scenarios are illustrated in the sample program below in the Steps to Reproduce Behavior section.

Generating a menu created in the Menu Designer produced the code used in the sample program. The code was copied from the .mpr file created when the menu was generated. The randomly generated names for the menu titles were changed to p1 and p2. The menu title that uses the ON SELECTION PAD command requires the double-click for its command to execute, which has Hello as the prompt.

Steps to Reproduce Behavior

1. Type the following code into a new program file and then run the program file:

         SET SYSMENU TO
         SET SYSMENU AUTOMATIC
   

         DEFINE PAD p1 OF _MSYSMENU PROMPT "Hello" COLOR SCHEME 3 ;
                 KEY ALT+H, ""
         DEFINE PAD p2 OF _MSYSMENU PROMPT "Get Back To Normal" ;
                 COLOR SCHEME 3 KEY ALT+G, ""
         ON SELECTION PAD p1 OF _MSYSMENU WAIT WINDOW "Hello"
         ON PAD p2 OF _MSYSMENU ACTIVATE POPUP getbackton
   
         DEFINE POPUP getbackton MARGIN RELATIVE SHADOW COLOR SCHEME 4
         DEFINE BAR 1 OF getbackton PROMPT "Red"
         DEFINE BAR 2 OF getbackton PROMPT "Blue"
         DEFINE BAR 3 OF getbackton PROMPT "Quit"
         ON SELECTION BAR 1 OF getbackton WAIT WINDOW "Red"
         ON SELECTION BAR 2 OF getbackton WAIT WINDOW "Blue"
         ON SELECTION BAR 3 OF getbackton SET SYSMENU TO DEFAULT
   
      The program should display a menu with a Hello pad and a "Get Back To
      Normal" pad.
   
   

2. Click the Hello pad and release the mouse button. If you are running FoxPro under OS 8, the menu pad will highlight. If you click the menu pad again, a WAIT WINDOW with "Hello" appears. With the Macintosh operating systems earlier than OS 8, the WAIT WINDOW "Hello" appears with the first click of the menu pad.

3. Try the "Get Back To Normal" menu pad. When the menu pad is clicked, the drop-down menu appears. Once the menu is down, the commands on the menu can be selected. With the Macintosh operating systems earlier than OS 8, the menu does not stay down when the mouse button is released. Select the Quit command to get the FoxPro menu back.
