# qtquick_customseparator In this example we illustrate how to provide a custom resize separator.
Here we list the main things to remember: - In your `CustomViewFactory` override `separatorFilename()` - Tell KDDW about your view factory `config.setViewFactory(new CustomViewFactory());`. - Optionally, call `config.setSeparatorThickness(2);` to control the thickness. This is not done via styling, as the layouting engine needs to know the value. The default is 5 pixels. - Implement your `MySeparator.qml` and put it into your QRC. Base it from our example, as we take care of some boilerplate. - If you set the thickness too small it might not detect mouse hover, but we improve that by increasing the `MouseArea`'s size by manipulating its margins
