Detailed Description

Wrapper around ERDAS Imagine Toolkit Viewer

Note:

Viewer keeps internal states for a connection and display handle. The side effects of openConnection(), selectExistingViewer(), and createViewer() are to update these internal states to reflect the new connection and display handles. These are accessed, respectively, via the connection() and displayHandle() members.

Member Function Documentation

void Imagine::Viewer::closeConnection (   )

close a viewer connection Imagine::ErrorReportException Problem closing a viewer connection

boost::shared_ptr<Evue_Connection> Imagine::Viewer::connection (   )

return the current viewer connection Note: boost::shared<Evue_Connection> because we make use of a deleter function that automatically insures that the connection is released when the last referring shared pointer is destroyed. Returns: the current viewer connection, or 0 if there currently isn't one

virtual boost::shared_ptr<Evue_Connection> Imagine::Viewer::openConnection (   )  [pure virtual]

open a connection to a running viewer Returns: A shared pointer to the connection. Remarks: XXX Or session manager? I'm not sure which. I think this just opens the pipe to the session manager and otherwise prepares for communication with a viewer through the session manager. Imagine::ErrorReportException Unable to open a connection to a viewer Implemented in Imagine::ClientViewer, and Imagine::EmbeddedViewer.

virtual void Imagine::Viewer::setStatusBar (  bool   )  [pure virtual]

Set whether viewer's status bar is visible or not Implemented in Imagine::ClientViewer, and Imagine::EmbeddedViewer.

virtual void Imagine::Viewer::setVirtualRoam (  bool   )  [pure virtual]

toggles on/off virtual roam feature Remarks: No idea what this is; as usual, poorly documented. >:o Precondition: viewer and its display is set up Imagine::ErrorReportException Unable to set virtual roam Implemented in Imagine::ClientViewer, and Imagine::EmbeddedViewer.
