Re: gtkmm / TreeView

[Murray Cumming <murrayc murrayc com>]

Here's an idea:

Both TreeViews use the same model. The model has a "selected" column.
The second TreeView puts the model in a TreeModelFilter, showing only
the rows where selected==true.

In general, please email gtkmm-list rather than me directly.
