#14: Deprecation of Slider
==========================

The Deprecation of the Slider Widget
************************************

Karabo is moving forward and will only support a single ``Slider`` widget
with Karabo **2.10.0**, which will be released **13.11.2020**.

The classic slider widget will be deprecated in favor of the ``TickSlider``.
For a rather smooth transition, the new GUI will reinterpret the scene information
of the classic slider and replace it with the Tick Slider.

The ``TickSlider`` has more features such as the step size configuration and an
option to show the value of the current slider position.
Hence, the currently set value on the slider can be seen before applying
(e.g. pressing *enter*) on the device.

**The geometry of the existing widgets are reused on the replacements to preserve
the scene layout.**
