@veer66 @xrevan86 gtk-rs doesn’t extend too much on the API, though there are some things that you do need to translate while working with it.

• Structs use Traits to translate inheritance from GObjects. So Widgets based on GtkWidget use the gtk::WidgetExt alongside whatever else it inherits. So GtkBox which is based on GtkContainer and GtkWidget implements gtk::WidgetExt and gtk::ContainerExt , and also uses IsA for gtk::Container & Widget

• Callbacks are handled with closures, and each type has a connect_signalname for each signal it emits. For gtk::Button which has the activate signal activate requiring just the Button being passed in, connecting would look like this:

button.connect_activate(move |button| {    // Optionally do stuff with button});

• Directly cloning GObject-based objects with .clone() can cause reference cycles. Instead, if you need to use an object in e.g. a closure and have it a you can use the following pattern:

let weak_widget = widget.downgrade();foo.connect_bar(move |_| {    // Not using foo, so not needed in closure    weak_widget.upgrade().map(|widget| {        // Do things with widget    });});// We can do more with widget here

I fed over 8,000 CNN Business headlines to a neural net to see which new headlines it would predict.
For some reason, it predicted companies behaving rather badly.
