/**

> Create and control a selectable drop down menu.

* **This class is a JS wrapper around Qt's [QComboBox class](https://doc.qt.io/qt-5/qcombobox.html)**

A `QComboBox` provides a means of presenting a list of options to the user.

### Example

```javascript
const { QComboBox } = require("@nodegui/nodegui");

const comboBox = new QComboBox();
comboBox.addItem(undefined, 'comboBox item 0');
comboBox.addItem(undefined, 'comboBox item 1');
comboBox.addItem(undefined, 'comboBox item 2');
comboBox.addItem(undefined, 'comboBox item 3');

comboBox.addEventListener('currentTextChanged', (text) => {
    console.log('currentTextChanged: ' + text);
});

comboBox.addEventListener('currentIndexChanged', (index) => {
    console.log('currentIndexChanged: ' + index);
});
```
