Excel Object Model: Button

A button object executes a macro when the user clicks on the button.

The button object is hidden (like, for example, the Global object).

  '
  ' Create/add the button.
  '
    dim btn as button
    set btn  = activeSheet.buttons.add( left := dest.left, top := dest.top, width := dest.width, height := dest.height)
    btn.caption  = "Click me!"

  '
    btn.onAction = "btnClicked"

end sub ' }

sub btnClicked() ' {
