# addonManager

## Purpose

Property that points to the AddonManager instance.

## Description

The `AddonManager` is responsible for handling all addons registered with the application. You can query it for info on any addon, for example, building a table with addon names and versions that can be used to display what capabilities are available in the application can be done in the following way.

First the Model

    import ca.odell.glazedlists.EventList
    import ca.odell.glazedlists.BasicEventList
    import ca.odell.glazedlists.SortedListclass AboutModel {
        EventList plugins = new SortedList(new BasicEventList(),
                     {a, b -> a.name <=> b.name} as Comparator)    void mvcGroupInit(Map<String, Object> args) {
            List tmp = []
            for(String addonName : app.addonManager.addonDescriptors.keySet().sort()) {
                GriffonAddonDescriptor gad = app.addonManager.findAddonDescriptor(addonName)
                tmp << [name: gad.pluginName, version: gad.version]
            }
            plugins.addAll(tmp)
        }
    }

Next is the View

    panel {
        migLayout layoutConstraints: 'fill'
        scrollPane(preferredSize: [320, 160], constraints: 'center') {
            table {
                tableFormat = defaultTableFormat(columnNames: ['Name', 'Version'])
                eventTableModel(source: model.plugins, format: tableFormat)
                installTableComparatorChooser(source: model.plugins)
            }
        }
    }

You'll require the `glazedlists` and `miglayout` plugins for this code to work.
