An overload Editor.GetWindow() extension method.

• • public static PromptWindowResult GetWindow(this Editor ed, string message, string secondMessage)

  • public static PromptWindowResult GetWindow(this Editor ed, string messageAndKeywords, string globalKeywords, string secondMessage)

  • public static PromptWindowResult GetWindow(this Editor ed, PromptWindowOptions options)

The PromptWindowOptions type provides the same features as PromptPointOptions more a SecondMessage read/write property.

The PromptWindowResult type offers the same properties as PromptResult (Stauts and StringResult) plus Value of type Extents3d (current UCS coordinates).
