    <p>I'm not sure if GIO allows you to have more than one monitor at once, but if it does there's no* reason you can't do something like this:</p> <pre><code>import gio import os def directory_changed(monitor, file1, file2, evt_type): if os.path.isdir(file2): #maybe this needs to be file1? add_monitor(file2) print "Changed:", file1, file2, evt_type def add_monitor(dir): gfile = gio.File(dir) monitor = gfile.monitor_directory(gio.FILE_MONITOR_NONE, None) monitor.connect("changed", directory_changed) add_monitor('.') import glib ml = glib.MainLoop() ml.run() </code></pre> <p>*when I say no reason, there's the possibility that this could become a resource hog, though with nearly zero knowledge about GIO I couldn't really say. It's also entirely possible to roll your own in Python with a few commands (<code>os.listdir</code> among others). It might look something like this</p> <pre><code>import time import os class Watcher(object): def __init__(self): self.dirs = [] self.snapshots = {} def add_dir(self, dir): self.dirs.append(dir) def check_for_changes(self, dir): snapshot = self.snapshots.get(dir) curstate = os.listdir(dir) if not snapshot: self.snapshots[dir] = curstate else: if not snapshot == curstate: print 'Changes: ', for change in set(curstate).symmetric_difference(set(snapshot)): if os.path.isdir(change): print "isdir" self.add_dir(change) print change, self.snapshots[dir] = curstate print def mainloop(self): if len(self.dirs) &lt; 1: print "ERROR: Please add a directory with add_dir()" return while True: for dir in self.dirs: self.check_for_changes(dir) time.sleep(4) # Don't want to be a resource hog w = Watcher() w.add_dir('.') w.mainloop() </code></pre>

    1. COThis gives me a really good starting point, thanks :) I see no reason that it wouldn't let me have multiple monitors. I'll just have to test it to see if it's too resource intensive, but since I'm looking at directories and not files, that might save me. Since I'm monitoring version controlled trees, it also gives me the flexibility to ignore admin directories (eg. `.svn` or `.git`).

    2. COI'll have to check whether I need to manually cancel and remove monitors for deleted directories or not.

    3. COYou could also create an ignore file and check filenames against the ones in the ignore file. The simplest way to do that would be just a file per line, and each time `f.seek(0)`, `ignorelist = f.readlines()`, `if change in ignorelist: #skip`

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
