PRB: InteractiveChange Event of List Box Does Not Execute After Clicking and Dragging a List Box Item

• Microsoft Visual FoxPro for Windows, version 6.0

SYMPTOMS

The InteractiveChange event of a list box does not execute when the mouse button is clicked on a list box item, held while the mouse pointer is dragged to another item in the list box, and then released.

MORE INFORMATION

Using Visual FoxPro 3.0 or Visual FoxPro 5.0, depressing the left-mouse button with the mouse pointer on a list box item, dragging the mouse pointer to another item in the list box and then releasing the mouse button causes the ListBox.InteractiveChange event to execute. However, the InteractiveChange event does not fire in Visual FoxPro 6.0.

Steps to Reproduce Behavior

1. Create a program file called "List.prg" using the following code:




PUBLIC ox
ox=CREATEOBJECT('listtest')
ox.SHOW
DEFINE CLASS listtest AS FORM
   HEIGHT = 168
   WIDTH = 169
   DOCREATE = .T.
   AUTOCENTER = .T.
   CAPTION = "Form1"
   NAME = "Form1"

   ADD OBJECT list1 AS LISTBOX WITH ;
      HEIGHT = 120, ;
      LEFT = 24, ;
      TOP = 24, ;
      WIDTH = 120, ;
      NAME = "List1"

   PROCEDURE INIT
      FOR i=1 TO 7
         THISFORM.list1.ADDITEM(REPLICATE('0', ;
            4-LEN(ALLTRIM(STR(i))))+ALLTRIM(STR(i)))
      NEXT
   ENDPROC

   PROCEDURE list1.INTERACTIVECHANGE
      =MESSAGEBOX(this.value,64,'InteractiveChange')
   ENDPROC
ENDDEFINE 




2. Click the left-mouse button on list box item "0001."



3. While holding the left-mouse button down, move the mouse pointer to list box item "0005."



4. Release the left-mouse button.



5. Note that the code associated with the list1.INTERACTIVECHANGE event is not executed.
   
   Using Visual FoxPro 3.x and Visual FoxPro 5.x, the list1.INTERACTIVECHANGE event code is executed.
