Re: [Gretl-devel] GUI enhancements

You may be interested to hear of some recent enhancments to the
gretl GUI. These are in CVS and the snapshots for Windows and OS
X.
Definitely interested!
* Re-ordering of series in dataset. Up till now the only way to
change the order of the series in a gretl dataset was to save
the data under a different name (selecting a revised order for
the series via the "store" command or the GUI dialog), then
copy the new gdt file over the old one. Now you can make
changes via the GUI. Select a series and either right-click
and choose "Edit Attributes" (or type "e") to get the Edit
Attributes dialog. This now has an "ID number" spinner which
lets you reposition the variable. (But note that if you have
defined named lists, or saved models, you will not be able to
make a change that disturbs the order of series that are
referenced by such objects.)
The problem here is that AFAIK there is currently no way to review the
lists that are defined. Maybe it's the right time to add the named lists
also to the session icon view?
* Re-ordering of regressors in the model selection
dialog. Suppose you have a list of regressors in place in the
right-hand pane of the model dialog, and for reasons of
presentation or comparability you want to change their
order. Up till now you would have to remove the regressors
from the list then refill it in the preferred order. Now you
can select one or more series names and right-click to get a
popup menu with Up and Down arrows. Use these to shift terms
as you wish. (But note that since the constant is always
automatically placed first in gretl output, this popup menu is
not available when the constant is selected.)
I very much like that functionality. What about alternatives to a pop-up
menu: drag-and-drop, arrow buttons? (Not all of them I mean, and caveat:
I haven't tried the current implementation yet.)
* Named lists of series. In the main window's Data menu there
are two new items: "Define list" and "Select listed
variables". "Define list" lets you create a named list; if
more than one series is selected when you choose this item the
selected series are shown as the default list-members (but you
have a chance to alter this). "Select listed variables" gives
you a dialog with a pop-down menu containing all
currently-defined lists: if you choose one, the members of
that list are automatically selected in the main window (so
you can then right-click to get summary statistics, a
correlation matrix, or whatever, for the listed variables).
Also nice. The term "select listed variables" strikes me as a little
confusing or misleading, though. Maybe "select list members"? (Not
perfect either I admit.)
I repeat: AFAICS that dialog with pop-down menu would currently be the
only place where the defined lists would actually be visible.
thanks,
