Details

The _refresh method invokes the _refresh method of all widgets that have the _needRefresh attribute set with the _needRefresh method. See _needRefresh in the Widget class for more details. The _refresh method is the same as the REFRESH statement.

When you invoke the _refresh method (or REFRESH statement) on a frame prior to the frame receiving a _postinit method, a _postinit method is sent to the frame, and then the refresh proceeds. This can occur if you invoke _refresh from the frame's _init method, the _initLabel method, or the INIT section.

If you call the _refresh method (or the REFRESH statement) from the frame's INIT section, it causes the _postinit method to run for the frame and all widgets before the _refresh method is sent to all widgets. Normally, the _postinit methods are sent after the INIT section finishes.
