Graphical class browser for Xt
The viewres program displays a tree showing the widget class hierarchy of the Athena Widget Set. Each node in the tree can be expanded to show the resources that the corresponding class adds (i.e. does not inherit from its parent) when a widget is created. This application allows the user to visually examine the structure and inherited resources for the Athena Widget Set.
To install viewres, paste this in macOS terminal after installing MacPorts
sudo port install viewres
