Class 'trackScalar'

Description

Instances of this class are coupled to a scalar variable, then display its current contents, tracking any changes made to it. Although the purpose of the class is the same as for watchScalar the means of displaying is different. While the former only shows the current value this widget will display the entire of the variable. A scrollable text widget is used to do this.
