I would advice you to use deleteLater on QObjects to make sure all pending events are removed.
You can use delete but then you'll have to remove the pending events yourself.

  Hi Tim





  Using Qt assistant Look for "Object Trees and Object Ownership"

  For more information in regards to Objects and threads see "Thread Support in Qt"   in section "Per-Thread Event Loop"

  Hi all,
  I am new to qt, and I have read some tutorials. 

  I found all of then use new to create objects, but never use delete to release. 

  Why?
