Below is an example of the Plugin Manager dialog. HEC-MetVue is deployed with some plugins and they are shown on the 'Installed' tab in the dialog. Notice that although the plugins are installed, many are not activated. The only plugins that are activated by default are for reading NetCDF and XMRG files. This is to provide backward compatibility with earlier versions of HEC-MetVue. In additon to the plugin providers shown, HEC-MetVue has built in support for reading its own native TIN and NEXRAD HRAP grid files as well as HRAP and SHG grids stored in DSS. Although the native file and DSS readers are plugins, they are not displayed in the Plugin Manager and cannot be deactivated.

The left side of the dialog tab shows the available plugins. Active plugins are marked with the symbol. The category lists the type of plugin. The right side of the dialog tab gives a description of the currently selected plugin. Plugins that are deployed with MetVe can be activated and deactivated. Plugins that are deployed with HEC-MetVue should never be uninstalled. These plugins are supplied in the various jars that accompany the deployment and are not contained in a separate ".NBM" module file.

In the event a plugin is accidentally uninstalled that was part of the original install, the most straighforward way to recover is to completely uninstall and reinstall the program following the instructions in this manual. The Plugin Manager activation and confirmation dialogs are illustrated below.
