How to tweak the variables, which a Lambda expression in Vala captures?

Question

How to capture this only weakly in a anonymous function?

I couldn\'t find anything in the docs regarding whether (or how) the variables cap

Answer 1

Inside a lambda, no. The standard approach is this:

class Foo : Whatever {

  public Foo {
    unowned Foo unowned_this = this;
    this.bar_signal.connect(unowned_this.bar_handler);
  }
  private void bar_handler() {
    ...
  }
}

This doesn't capture a reference to this, but you also cannot capture any other variables.
