In LabVIEW 8.2 , The Preference Dialog Appears Like Below;

In the directory of resource\dialog\PreferencesDialog you can find the PreferenceDialog.vi, the UI looks like the image as below:

and in the directory of \resource\dialog\PreferencesDialog\PreferencePages you can find all PreferenceDialog pages, such like prefPage_BlockDiagram.vi look like the image as below:

so I guess the PreferenceDialog.vi embodied the page Vis User Interface,When user select one item, the PreferenceDialog.vi embody the selected page vi realtime, and I think this may be implement by subPanel, But I can't realize it. Any one know the secret of PreferenceDialog? thanks a lot?
By the way, this is one way to implement plugins archetecture?

In the same directory, there's also a template to build your own pages (i guess), called pageTemplate.vit with an unlocked diagram. it's window title is "Use VI Window Title as Category Name"
you'll probably be able to figure out how the dialog works from that. it has this comment in the "PanelClose?" event case:

"This is useful during development,
so you can run your page VI without
the dialog framework.
When running in the frame VI's subpanel,
you should never get a panel close event."

This is very nice of NI, I think they did this on purpose (really). I haven't looked at it yet but it sound very promising!

Yes, it seems to be realized with subPanel.
Probably attached "quick and dirty" VIs will be helpful for you?

Yes, the example Andy shows is exactly how we used the subpanel in the Preferences Dialog. We use the listbox/subpanel plug-in architecture for a number of things in LabVIEW. The Library Properties Dialog is similar and contains different pages whether you have a normal project library or are using a special type of library like a class. The VI Analyzer uses a similar method to load all tests and display the individual configuration parameteres for each test.
