This contains the Lspinner class for Locana. The Lspinner class is a textbox with two small buttons on the right to increment/decrement the value in the textbox. You can provide your own on_increment and on_decrement events or use the following defaults:

• If you provide a :text attribute as an array, the these values are used for incrementing/decrementing.
• Otherwise if :value is a string, succ! and decc! are used on the string value
• Otherwise if :value is a number then +/- 1 is used

Features:

• Written in 100% Ruby using only Locana, it is a nice example of how to use Locana.
• Allows you interactively/graphically increment/decrement the value.
• The following keys work:
  • Up arrow - adds one
  • Down arrow - subtracts one

Status:

• Working

To do:

• None
