Methods

  • GtkTryExpression (n_expressions = null, expressions = null)

    Creates a GtkExpression with an array of expressions. When evaluated, the GtkTryExpression tries to evaluate each of its expressions until it succeeds. If all expressions fail to evaluate, the GtkTryExpression's evaluation fails as well. The value type of the expressions in the array must match.

    • @p n_expressions is The number of expressions.
    • @p expressions is The array of expressions.
  • toNativeHandle (Source)

    Normalizes a constructor argument into a raw pointer carrier. Accepts a raw NativeHandle, a raw NativeBuffer returned from fn.call(...), another generated wrapper exposing handle(), or null. Returns null when the argument carries no pointer.

    • @p Source is the raw handle, raw buffer, wrapper, or null.
    • @r A raw pointer carrier or null when no pointer is present.
  • getLib ()

    Returns the opened native library for this generated wrapper.

    • @r The opened native library.
  • handle ()

    Returns the wrapped NativeHandle.

    • @r The wrapped NativeHandle.
  • isNull ()

    Returns true when the wrapped handle is null.

    • @r A bool.
  • describe ()

    Returns a small string for debugging generated wrappers.

    • @r A string.
  • asExpression ()

    Wraps this handle as GtkExpression.

    • @r A GtkExpression object.
