General Question about Handlers & Commands [message #484494]

I can set state to a command using the State object, but what is the exact
same paradigm for a handler? In other words how to I set set State or
something similiar to a handler. The handler parameters will not work for
me because they only support strings.

thanks.

Hi,

I'm not sure if that is your question but you can use your own
AbstractSourceProvider for example to enable your commands.

This is described here:

Best regards, Lars

Once you inform the command that it has a state object, you can easily get access to the state by subclassing org.eclipse.core.commands.AbstractHandlerWithState

When a handler becomes active, it is handed the current state from the Command.
