Implement data manager

This will be implemented with a new Data Manager mechanism.

I'll use this ticket to document what I want to do with a data manager now.

We should have a data manager, viewing some kind of logical tree of data. This will allow filtering (e.g., only conflicting, only new, etc.), searching, etc. It will allow data to be accepted (and likely edited), and will also allow for data to be removed. Logical keyboard navitgation should be provided.

I've started working on the UI for this in data-manager.glade.

More things that need to be done with this: Once it's possible to delete data values, we need to actually remove those values from the XML data. This will require some re-thinking of how PropSet's are handled, most likely. Some kind of linkage so we can actually delete the xml data is needed. Whether this happens immediately or at want_save is unknown; whatever seems to work best works.

I think I'll have Brandon work on this one. A nice comprehensive project.

I've started on the UI layout in data-manager.glade; you'll need Glade to manipulate that file. Glade can be had from MacPorts? (aka DarwinPorts?), which is installed on the Intel mac (you're using it to provide the classic Unix environment Goanna needs to build).

You'll want to wait to really dig into this until I'm done with #285 and the changes that will happen with that - it'll make your life much, much easier.

To do this cleanly, a custom GtkTreeModel should be written to provide the data behind the property tree that the user will be editing.

This should require some noticable additional capabilities in the Goanna model, I think.

Goanna/DataManager documents work on this.

(In [1862]) References #365. Branching to implement the data manager.

Actually, I'll be working on this one.

(In [2040]) References #365. Work towards making NotifyingListModel? more general, and supporting trees. It breaks things though - lists only display 1 element.

(In [2041]) Refs #365. Fixed the NotifyingListModel to actually work again, and added more logging.

(In [2043]) Refs #365. Updated interface between the NotifyingListModel and its adapters.

[2042] also works on this.

(In [2044]) Refs #365. Some (untested) code to work on building a notifying_list tree.

(In [2049]) References #365. Initial data manager code (really does nothing).

(In [2050]) Refs #365. Some more work towards the models (still no data on screen).

(In [2051]) A bit more, mostly cleanup. Refs #365.

(In [2052]) Refs #365. Working NotifyingTreeModel code, so the data manager now displays a tree.

(In [2054]) References #365. Several enhancements wrt labelling.

(In [2057]) References #365. Added display info for network devices.

[2058] also works on this...

(In [2132]) Refs #365. Adds status indicators to data manager icons.

(In [2134]) Refs #365. Fixed object destruction order in MainWindow so the DataManager doesn't crash at shutdown.

(In [2155]) Several nice new things for the networking display and data manager. Refs #365.

(In [2158]) Refs #365. Added some more niceness to the data manager. Now crashes at shutdown though.

(In [2159]) Fixes shutdown behavior in the data manager (refs #365).

• Made the DataManager kill itself at window close.
• Added signal_shutdown() to DataManager and made MainWindow use this to clear its pointer

(In [2161]) Several enhancements and improvements on the data manager, as more features come along! Refs #365.

(In [2163]) Refs #365. More work on this data manager.

(In [2164]) Wired property source-supplied value accept buttons. Refs #365.

(In [2167]) Refs #365: more DataManager? UI enhancements.

• Added version detect for the GtkButton "image" property, so we still use it if it's available
• Added tooltips and put them on a few widgets which are programatically added.

(In [2171]) Refs #365. Re-vamped the property mechanism to use types, templates, etc. Should help provide useful behavior in the future.

(In [2175]) Refs #365. Adds more UI for the data manager. Also fixes s GLib warning in the node viewer.

(In [2177]) Got some working accelerator things done. Refs #365.

(In [2178]) Refs #365. Added support for displaying parents of conflicted items but not considering them conflicted.

• Adds the SavedObject::walk() method, for walking a data tree.
• Reworks filtering in the DataManager, to use a memoization table and other nifty things.
• Added a recur parameter to SavedObject::get_status(), for specifying whether the status ought to examine child status.
• Added the SavedObject::get_child_objects() method to create a non-notifying list of child objects.

(In [2184]) Refs #365. Adds support for editing network ports.

(In [2195]) Added a new metaphor for "add", and made buttons use it. Also added support for displaying network devices in the data manager. Refs #365.

(In [2198]) Refs #365. Adds support for deleting nodes to the data manager.

(In [2200]) Refs #365. Fixes code so that it doesn't crash when deleting a node.

• Added support to the topography to watch for node deletions
• Made MainWindow clear the selection and suspend the system prior to tearing it down

(In [2207]) Refs #365. Adds support for deleting nodes and tracking those deletions in the topography model.

Correction: this adds delete-network-device support, not node.

(In [2208]) Added support for adding nodes to the Data Manager. Refs #365.

(In [2209]) Refs #365. Set the New Items checkbox to be checked when the data manager starts for a better UI experience.

(In [2211]) Refs #365. Adds support for adding network devcies.

This can use a few more features here and there, but I'm going to call it done. Troy, have fun.

Forgot the ticket changes.
