Re: How do I watch a file for changes using JS/Gnome Shell? [SOLVED]

[Stefano Ciancio <s ciancio gmail com>]

Hi all,

with the help of Giovanni I succeeded in writing  an extension with file 
monitoring.

In the following some parts of my code:

----

TestMonitor.prototype = {
    __proto__: PanelMenu.SystemStatusButton.prototype,

    _init: function() {
        ...
        let FILE_TO_MONITOR = '/path/of/file/to/monitoring';

        let file = Gio.file_new_for_path(FILE_TO_MONITOR);
        this._monitor = file.monitor(Gio.FileMonitorFlags.NONE, null);
        this._monitor.connect('changed', Lang.bind(this, this._onChanged));
        ...
    },

    _onChanged : function () {
        global.log("Something has happened!");
    },
...

Thanks to all,

   Stefano
