| 47 | \brief The QStylePlugin class provides an abstract base for custom QStyle plugins. | - |
| 48 | - | |
| 49 | \ingroup plugins | - |
| 50 | \inmodule QtWidgets | - |
| 51 | - | |
| 52 | QStylePlugin is a simple plugin interface that makes it easy | - |
| 53 | to create custom styles that can be loaded dynamically into | - |
| 54 | applications using the QStyleFactory class. | - |
| 55 | - | |
| 56 | Writing a style plugin is achieved by subclassing this base class, | - |
| 57 | reimplementing the pure virtual create() function, and | - |
| 58 | exporting the class using the Q_PLUGIN_METADATA() macro. | - |
| 59 | - | |
| 60 | \snippet qstyleplugin/main.cpp 0 | - |
| 61 | - | |
| 62 | The json metadata file \c mystyleplugin.json for the plugin needs | - |
| 63 | to contain information about the names of the styles the plugins | - |
| 64 | supports as follows: | - |
| 65 | - | |
| 66 | \quotefile qstyleplugin/mystyleplugin.json | - |
| 67 | - | |
| 68 | See \l {How to Create Qt Plugins} for details. | - |

| 76 | Creates and returns a QStyle object for the given style \a key. | - |
| 77 | If a plugin cannot create a style, it should return 0 instead. | - |
| 78 | - | |
| 79 | The style key is usually the class name of the required | - |
| 80 | style. Note that the keys are case insensitive. For example: | - |
