In the original ooDialog implementation, the arguments sent to the event handlers for different controls included the window handle and resource ID of the control.
For C / C++ programmers, the window handle is essential to working with the control. However, this is not very useful to Rexx programmers. What Rexx programmers really need is the Rexx control object, not the windows control window handle.
For all event notifications sent from a tab control, add the Rexx Tab object as the third argument sent to the event handler.
Already implemented, just need doc.
