Detailed Description

QLSlider Example

A QLSlider is a QLWidget that provides a mechanism for changing a numerically-valued LAttribute within a limited range.

If you need a slider that can fit into smaller spaces, consider using a QLMiniSlider.

By click-dragging on the slider handle, a user can change the attribute linked to it.

The following demonstrates how to link the slider's value attribute with another attribute: 

QLWidget* widget = new QLWidget;
QLSlider* slider = new QLSlider(30.0);
 
slider->value()->set_link_attribute(widget->border_thickness());

In the example, after the call to LAttribute::set_link_attribute(), the widget's border thickness will change when the slider is interacted with.
