Detailed Description

The vector tree view.

This class is used to add and remove vectors to and from the vector store by the user. It also presents the content of the vector store to the user of course. Further, it has a context menu for the vector operation such as the cross product etc. It also provides signals to notify other objects about the state of selection and whether or not it wants something having displayed in the status bar.

Remarks:: This class operates heavily on the vector store, but the vector store is defined in the NTab class. This class has only a reference to that vector store.
