Vala code snippet that implements Model-Update logic for a counter app using a library called Styx. It defines the "CounterModel" to store the state ("count"), the "CounterIncrementPressed" and "CounterDecrementPressed" messages for user actions, and the "CounterUpdater", which contains the "update" function to modify the model state according to the message received.
GTK Blueprint code snippet that defines the interface of a counter app. It shows integration with a library called Styx using "Styx.Builder". The interface contains a label whose text is bound to the "count" value of the data model, and two buttons, "+" and "-", which dispatch the "increment" and "decrement" messages to update the state.
what if we could implement the MVU (Model-View-Update) pattern in GTK 4 in such a declarative way?
