Detailed Description

Extend the ctkDoubleSpinBox to integrate units support.

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

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 spinbox are updated by units and which aren't.

Property Documentation

◆ quantity

QString qMRMLSpinBox::quantity

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 65 of file qMRMLSpinBox.h.

◆ unitAwareProperties

UnitAwareProperties qMRMLSpinBox::unitAwareProperties

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 are on by default.
