| 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. | - |
| 64 | - | |
| 65 | \code | - |
| 66 | { "Keys": [ "myiconengine" ] } | - |
