[Gambas-user] Ideas? New tri-state control

[adamnt42 at ...626...]

(We're just having a little think session here)

Looking for the a good example of how to do a "draw it yourself" control.  

The control in question represents the value of a tri-state variable with the values "Up", "Down" or "Not set" (out reasons are arcane but consider something you want to specify a "default sort" for). So it would look like a checkbox but instead of tick boxes it would have a pair of arrow images and a "null" box.
