Hi everybody,
I run into an issue while developing an extension for Gnome Shell.
Long running Javascript code can make the whole Gnome Shell unresponsive
for a second. Since I cannot reduce the execution time of the long running
code, I want to move it out of the main loop's thread to a new one to make
the UI update independent. I found that the best way would be to create a
GTask <https://developer.gnome.org/gio/unstable/GTask.html> to run my
synchronous JS code asynchronously.
So I tried something like this:
let task = imports.gi.Gio.Task.new(
Lang.bind(this, function(){ /* do the heavy work */ }),
null,
Lang.bind(this, function(){ /* handle the result when ready */ }),);
But that does not work, because the first argument is not a *GObject*, but
a JS function.
I think that a passing a GClosure
<https://developer.gnome.org/gobject/unstable/gobject-Closures.html>
instead could work. Here is how I tries to instantiate it:
let closure = new imports.gi.GObject.Closure(function(){}, new
imports.gi.GObject.Object);
Unfortunately this does not work either, probably the first argument has to
be a *GCallback*.
Can I get some assistance?
Thanks in advance.
Regards,
Geza
