46 \class QIconEnginePlugin
47 \brief The QIconEnginePlugin class provides an abstract base for custom QIconEngine plugins.
48
49 \ingroup plugins
50 \inmodule QtGui
51
52 The icon engine plugin is a simple plugin interface that makes it easy to
53 create custom icon engines that can be loaded dynamically into applications
54 through QIcon. QIcon uses the file or resource name's suffix to determine
55 what icon engine to use.
56
57 Writing a icon engine plugin is achieved by subclassing this base class,
58 reimplementing the pure virtual function create(), and
59 exporting the class with the Q_PLUGIN_METADATA() macro.
60
61 The json metadata should contain a list of icon engine keys that this plugin supports.
62 The keys correspond to the suffix of the file or resource name used when the plugin was
63 created. Keys are case insensitive.

66 { "Keys": [ "myiconengine" ] }
