Sliders are much like Gauges, except they also allow for interaction by the user (rather than just showing a level).

To implement a slider in guiDesigner:

1. Select the slider icon on the tool bar.
2. Then draw a box roughly the size of the slider you wish to use. This size can be edited later on.
   
3. You will then need to add a theme to the slider. To do this, select a slider theme from the Theme Library and drag it onto the slider you just added.

You can also drag a slider theme directly from the Theme Manager or Theme Library onto an empty spot on an open page, and the slider will be automatically created at the drop point and assigned the theme you dragged.

Whats the difference between a gauge and a slider?
Good question! A gauge takes a reading from a device/system, and displays the level as a visualisation. A slider is a control that the user can manipulate to change the level of the device/system.
