If you are referring to the Qt connect(), PlugIns are not (necessarily) QObjects so you can't connect() a plug-in. There are two signal/slot mechanisms in Options: the Qt connect() mechanism and the Opticks attach() mechanism. Aside from GUI events, most signal/slots use the Opticks method and this is what I was referring to in my previous message. Look in the Opticks documentation for Subject if you would like more information. If you want to listen for all created elements in a plug-in then your plug-in has to be a "manager" plug-in. You can look at the ASPAM plug-ins for an example of this pattern. http://opticks.svn.sourceforge.net/viewvc/opticks/trunk/future/Code/appl ication/PlugIns/src/Aspam/ If you can explain more about your goal we may be able to suggest a simpler way to reach that goal as the above is fairly complicated to implement.

In the case of the histogram, it listens to the WindowActivated signal on DesktopServices. IF you want to know when a new data element is created, you can listen to the ElementCreated signal on ModelServices. This doesn't fire when the data is loaded, but before when the element is created. If you want to know when the data is loaded, listen to that signal then attach to DataModified on the RasterElement. -----Original Message----- From: speedinghong [mailto:spe...@qq...] Sent: Wednesday, August 31, 2011 4:36 AM To: opt...@li...
