Hi Joe.
If you middle-click (or whatever it is on your system) on a GUI
element you get the "Halo" with the name of the selected element
written at the bottom of the Halo. This always starts with the
top-level widget (the window for example) but if repeat the
middle-click over a button for example, you descend down the widget
tree.
So if you repeatedly middle-click on a button in a dialog box,
you'll will eventually get the Halo for that button where you can
see what Morph this is and use the Halo buttons to inspect, explore,
... the Morph.
You can then see that it is a PluggableButtonMorphPlus which you can
use like this:
button := PluggableButtonMorphPlus new .
button label: 'Hello World' .
button action: [ Transcript cr ; show: 'Hello World'] .
button openInWorld .
