PRB: Property is Ignored Under Program Control

ID: Q127845

3.00 WINDOWS kbprg kbprb

The information in this article applies to:

  - Microsoft Visual FoxPro for Windows, version 3.0

SYMPTOMS

Assigning a value to a property in a class definition has no effect at run time. The value of the property is ignored.

CAUSE

The property, or any property that affects it, is misspelled or not assigned to the correct member object. A new property is therefore declared, and no error message is generated.

RESOLUTION

You can use the DISPLAY OBJECTS command or the Amembers() function to verify that all of the attributes of an object hold the correct value.

For more information about DISPLAY OBJECTS or Amembers(), refer to Visual FoxPro Help.

STATUS

This behavior is by design.

MORE INFORMATION

Steps to Reproduce Behavior

When running the following sample program, the ToolTipText property does not display any text. The reason for this behavior is that the ShowTips property, which specifies whether or not a tool tip can be displayed for a control, is set as a property of a control instead of a property of the form.

   frmTest = CREATEOBJECT("FormToolTip")
   frmTest.Show
   READ EVENTS

   DEFINE CLASS FormToolTip AS FORM
       * Uncomment the line below for the ToolTip to display.
       * ShowTips = .T.
         Caption="No tool Tip for the Text Box"
    ADD OBJECT text1 AS textbox
       * Incorrect setting for the ShowTips property
        text1.ShowTips = .T.
        text1.ToolTipText = "This is the Text"
        text1.left=(thisform.width-this.text1.width)/2 && center text box
    PROCEDURE Destroy
        CLEAR EVENTS
    ENDPROC
   ENDDEFINE
