Detailed Description

Extend the ctkSliderWidget to integrate units support.

This custom widgets extends the ctkSliderWidget widget to integrate the unit support within Slicer. By default, this widget behaves just like a normal ctkSliderWidget.

To use the units, one needs to set what kind of quantity this widget should look for. For example, when dealing with world positions, the quantity is probably going to be "length". Once a scene is set to this widget, it listens to the changes made upon the selection node to extract the unit properties related to its quantity and update accordingly.

To allow even more customisation, one can set which properties of the widget are updated by units and which aren't.

Property Documentation

◆ quantity

QString qMRMLSliderWidget::quantity
readwrite

Get/Set the quantity is used to determine what unit the spinbox is in. This determines the spinbox properties like minimum, maximum, single step, prefix and suffix.

Definition at line 64 of file qMRMLSliderWidget.h.

◆ unitAwareProperties

UnitAwareProperties qMRMLSliderWidget::unitAwareProperties
readwrite

Get/Set the properties that will be determined by units. If a property is aware of units, it will update itself to the unit's property value automatically. Otherwise, this property is left to be changed by its accessors. All flags except MinimumValue and MaximumValue are on by default.
