I wanted to use a keyboard or a mini keyboard widget for a Roku channel. Rendering a keyboard on the display is straight forward however I cannot find any information on creating an observer for the keyboard entry and how one goes about selecting the string just entered on the keyboard. The Roku docs offer this:
In a real application, you would probably want to group the MiniKeyboard node with a Button node (or possibly a ButtonGroupnode) to allow the user to inform the application that the string entry is complete (or possibly canceled).
I cannot figure out how to actually do this.
