You get this "for free" when you use a full-blown Dabo app with a Dabo
Application object. The user can drag columns around, resize them, and
the changes "stick".
You could probably manually set up a dPref (Dabo Preference Manager) but
I'll leave that for Ed to answer because I've not done it and he knows
the inner workings.
Perhaps (I don't know) you could get away with instantiating a dApp at
the beginning of your program:
import dabo
app = dabo.dApp(MainFormClass=None, UI=None)
app.setup()
Having that instantiated may just make enough of Dabo work to get the
dGrid preferences saved.

In your dGrid subclass, define a event handler and set up the event binding:
class MyGrid(dabo.ui.dGrid):
...
def onGridHeaderMouseRightClick(self, evt):
# do your stuff

There isn't a Visible property for columns (perhaps there should be).
You can call grid.removeColumn(columnIndex).
I don't understand the second part of the question. If it is a class
that defines which columns to show, just write the code in the subclass.

Glad you are enjoying it. Keep asking questions.
