FIX: WHEN Clause Not Invoked When Bar Is Moved

The information in this article applies to:

• Microsoft FoxPro for Windows, version 2.5

SYMPTOMS

Moving a bar does not invoke the WHEN clause in a popup defined with the MOVER clause. The expected behavior is for the WHEN clause to be invoked every time the bar is moved.

STATUS

Microsoft has confirmed this to be a problem in FoxPro 2.5 for Windows. This problem was corrected in FoxPro 2.5a for Windows.

Steps to Reproduce Problem

1. Create and run a program with the following code:

         DEFINE POPUP test MOVER
         DEFINE BAR 1 OF test PROMPT 'one'
         DEFINE BAR 2 OF test PROMPT 'two'
         DEFINE BAR 3 OF test PROMPT 'three'
   

         @ 10,10 GET x POPUP test DEFAULT 1 WHEN mywhen()
         READ
   

         PROCEDURE mywhen
         WAIT WINDOW 'In WHEN'
   

2. Note that the WAIT WINDOW, which is called by the WHEN clause, is displayed immediately.

3. Click and release bar "one." The WAIT WINDOW clears.

4. Click the button on bar "one" and drag it to another position. Release the mouse button.
