> Create and control system tray icon.
|
||
|
||
**This class is a JS wrapper around Qt's [QSystemTrayIcon class](https://doc.qt.io/qt-5/qsystemtrayicon.html)**
|
||
|
||
A `QSystemTrayIcon` provides ability to add and manipulate native system tray icon.
|
||
|
||
### Example
|
||
|
||
```javascript
|
||
const { QSystemTrayIcon, QIcon } = require("@nodegui/nodegui");
|
||
const trayIcon = new QIcon(
|
||
resolve(__dirname, "some/image/file.png");
|
||
);
|
||
const tray = new QSystemTrayIcon();
|
||
tray.setIcon(trayIcon);
|
||
tray.show();
|
||
|
||
global.tray = tray; // prevents garbage collection of tray
|
||
```
