Create a GLibSynchronizationContext that sends code to be run on the
GLib main loop, and set it as the current SynchronizationContext in
Gtk.Init().
When you use the await keyword to do a task asynchronously, by default
the awaiter will capture the current SynchronizationContext, and if
there was one, when the task completes it’ll Post the supplied
continuation back to that context, rather than running it on whatever
thread it wants.
This means that if you use the async/await keywords in your Gtk# app,
things will now work as expected with the GTK main thread. For example:
static async void DoWork () // called in the GTK main thread
{
// Do some stuff with the UI...
label.Text = "Starting Work";
// Run something asynchronously, UI is not frozen
int res = await DoLongOperation ();
// Do some more UI stuff, it'll run on the GTK main thread
label.Text = "Work done";
}
