Hi,

The base widget is intended to be a reusable array sorting dialog for MR
Images. It is called from an event occurring in its group leader base widget,
and passed the image array by UVALUE at that time. Once the base widget is
called I want it to examine the array and initialize various aspects of the
dialog according to information gleaned. My approach to this has been to look
for a widget event like OnCreation or OnActive (I've previously used these to
initialize dialogs in motif) to start the initialization process.

Thinking about it, OnCreate is the wrong place for the initialization and an
OnActive or OnMapped event would be the point where the widget had enough
information to tailor itself for use.

Widget_Control, /Send_event may well work.

Do widgets in idl still generate the same events as the underlying OS
widgets. Is it just that Xmanager only picks up idl supported events?

Sorry if this is still unclear, but the RSI documentation on PostCreation led
me to believe that an event was generated after widget creation and all I
needed was to know the tag name to plug into the event handler.

Thanks

Marc
