问题 Ok so I have a controller with a method in which I want to load a view. How do I load a view from a controller? How do I pass some parameters from the controller to the view when I load it? Any help is much appreciated. 回答1: To load a view, you can use Ext.widget() . Use Ext.define() to create a view in your view file. I would recommend using the alias property to define an inline xtype for the view. When you need to load the view, you create an view using Ext.widget() and specify the xtype

问题 I'm making a game for an assignment. I have a server and multiclient set up in Java and we're using MVC. I need to have a client send their name to the server and then when two players are present I need to send both names back to the clients along with which player number they are (player one or player two). I don't get how I could tell which thread the information is coming from or which thread the information is getting sent to so not all players think they are player one. Thanks. 回答1:

问题 I want to use JavaFX properties for UI binding, but I don't want them in my model classes (see Using javafx.beans properties in model classes). My model classes have getters and setters, and I want to create properties based on those. For example, assuming an instance bean with methods String getName() and setName(String name) , I would write SimpleStringProperty property = new SimpleStringProperty(bean, "name") expecting that property.set("Foobar") would trigger a call to bean.setName . But
