How do i add checkboxes?

[th3lurker]

Back again with another problem.
What's the code for adding a checkbox to a dialog box? I've searched everywhere. I want to redo the "Show/Hide Layers" with and auto-update option(not sure about this one yet). BTW is OnChange available in ruby/sketchup? More importantly i want to organize the layers differently(not in the order of creation, two columns(left/right side of house), yada-yada-yada). I can handle that, but i can't do anything without checkboxes, cause drop down menus would be quite a compromise.
Thanks

Nope, no checkboxes built into the SketchUp ruby interface. You would have to make a webpage that acts as the layer manager. Then you can do checkboxes no problem.
