PRB: Form with DeskTop=.T. Changes the Left or Top Properties (141911)

MORE INFORMATION

Steps to Reproduce Behavior

Example One

1. Create a form, and set its DeskTop property to true (.T.).
2. Run the form and in the Command window type:

   <formname>.Left = 100

The form will move to position 100 but the form will also move up.

NOTE: A similar behavior occurs if, after the form is visible, the FoxPro desktop is moved and the form's Top property is changed. The form's Left property will be affected.

Example Two

1. In the form's Click event, place this code:

      ThisForm.Left = ThisForm.Left + 100
   						

2. Run the form, and note that the Example One behavior is exhibited.
3. Create two new properties for the form:
   
   
   • OrgLeft to hold the form's original Left property.
   • OrgTop to hold the form's original Top property
4. In the form's Init event, place this code:

      This.OrgLeft = This.Left
      This.OrgTop  = This.Top
   						

5. Add a "Move to the Right" command button with the following code in its Click event:

      ThisForm.Top  = ThisForm.Top - (2*ThisForm.OrgTop)
      ThisForm.Left = ThisForm.Left + 100 - (2*ThisForm.OrgLeft)
   						

   NOTE: This moves the form 100 pixels to the right of its current position.
6. Add a "Move to the Bottom" command button with the following code in its Click event:

      ThisForm.Top  = ThisForm.Top  + 100 - (2*ThisForm.OrgTop)
      ThisForm.Left = ThisForm.Left - (2*ThisForm.OrgLeft)
   						

   NOTE: This move the form 100 pixels to the bottom of the current form position.
7. Run the form and observe the behavior.
