Detailed Description

This class was created as a simple way to organize information dialogs.

In an of itself it does nothing, but, subclasses can implement pure methods to create and manage info dialogs. To properly be removed from the internal list this class creates, the info dialog must emit a closing(this) signal when it wants to be removed

Default Constructor.

Destructor.

Member Function Documentation

virtual void DtInfoHandler::showInfo ( const DtModelData &  )

virtual

Shows an info panel for the specified model data.

This routine will create a new info dialog, make some Qt connections to make sure it updates when items change on the screen and show it. To extend the functionality of the default entity info dialog create a subclass of this dialog and set the creator function in the pvdFactory instance. Due to the nature of the connections made to update this dialog it is not recommended that this method be overridden and not called by the subclass.
