RE: [Repast-developer] TextDisplay height/width

[Nick C. <nic...@ve...>]

Ah. I think I see. TextDisplay contains an inner class Box that contains
the dimensions and the location of the text box. There is also a private
field box of this type. It sounds like it would be enough if this field
was protected and there was a method like getTextBox that returned the
box itself.

For instance, if you want to customize the TextDisplay to have a certain background color, you could draw a rectangle underneath the TextDisplay the size of the TextDisplay's box. This could be done in a subclass's drawDisplay, after the TextDisplay.drawDisplay. I'm not sure if this made anymore sense so for instance:
