Pipeline Transfer to Client Side

Element Inspector

● Improvements– Should use same mechanism charting uses to

pull data to client side for display.– Make several smaller requests instead of one

request for data based on what data is currently visible in the view.

Object Inspector

● pqObjectInspector – Implements QAbstractItemModel. It is a wrapping of the properties of a proxy.

Object Inspector● Custom Property Pages

– A method of adding custom panels was added in pqObjectInspectorWidget.

– ui file created in Qt designer, and widgets are named after the property they represent.

– widget properties are linked with vtkSMProxy's properties

Object Inspector

● pqSMAdaptor – Qt based interface for setting and getting proxy properties.

pqSMAdaptor

– Get and Set properties using QVariant– Supports all Property types (enum, int,

double, etc...) except Proxy Property

Object Inspector

● Improvements– Support Proxy Properties with pqSMAdaptor

● Frees the application from having pointers to proxies, which may go stale.

– Support auto generated panels?– Perhaps implement another custom panel

method.● We don't have much control over ui file

compatibility.
