Code Behind is a workflow where you associate code with an instance of a node instead of a type.
In Code Behind you write code that you want to associate with the view or controller parts of the model-view-controller pattern.
All Activity Host code behind classes inherit from this class.
|
protected |
Wraps a given native CodeBehind.
Called by KanziObject#connectObject(long) when connecting to a native CodeBehind.
|
staticprotected |
Iterable<String> iterateCommands | ( | ) |
Gets an Iterable used to iterate commands handled by this code behind object.
|
protected |
Registers a new command handler.
A command is a form of user input. The code behind class of a node can register a handler for a command and perform an operation in the handler. You must call this method in CodeBehind#registerCommandsOverride.
commandName | The name of the command that you want to handle. |
handler | The handler functor for the command. |
|
abstractprotected |
Override this method to register commands.
You must register every command using CodeBehind#registerCommand. Kanzi registers commands when it attaches the node that uses this code behind.
|
protected |
Unregisters a command handler.
You must call this method in CodeBehind#unregisterCommandsOverride.
commandName | The name of the command for which you previously registered a handler. |
|
abstractprotected |
Override this method to unregister the registered commands.
You must unregister every registered command using CodeBehind#unregisterCommand. Kanzi changes the status of a command to unregistered when it detaches the node that uses this code behind.
