Retrieving and Setting a Window's Title

The title of a Window is usually displayed along the top of the window's frame. A title can be set upon the creation of a Window, but it can also be updated.

set_title and title=

A window's title can be set with the set_title method:

# window's title is "Winston the Window"
window = Window.new(title: "Winston the Window")

# window's title is now "Walter the Window"
window.set_title("Walter the Window")

Alternatively, you can use the title= method to achieve the same thing:

# "Winston the Window"
window = Window.new(title: "Winston the Window")

# "Walter the Window"
window.title = "Walter the Window"

set_title and title= must be called from within a run block definition.
