[Opengc-devel] multiple data sources?

[Wendell T. <we...@ad...>]

I am trying to add another data source, specifically to the
NavTestGauge, but it isn't working.  I was wondering if someone
could provide some assistance.

I want to have another udp input stream, similar to
ogcFGDataSource.cpp.  It would receive target data and display
them on the Nav Test Gauge (somewhat like TCAS).

I tried to follow how the FGDataSource is used (create a new
instance in ogcAppObject.cpp; create a Set function in
ogcRenderObject.h and ogcRenderWindow.cpp).  These seem to work
fine, as the new data source class is called, and the socket is
opened.

I think the OnIdle gets called, and reads the socket and parses
the data.

However, in the ogcNavTestComponent.cpp, the class seems to have
been lost.  It seems as if there are multiple instances of my
new ogcTGDataSource class, and the instance doing the
initializing and reading isn't the instance that the
NavTestComponent has visibility to.

I could have just jammed the udp reading into the FGDataSource
section, but thought that possibly this was a better way.

Suggestions?
