The 'limit' property

Integer scalar (numeric scalar for Splitter)

Valid for: Edit, RichEdit, Combo, Splitter

For an Edit, RichEdit or Combo control, the limit property determines the maximum number of characters which the user can type into the control. If this value is 0 (which is the default), there is no application-defined limit.

For a Splitter, the limit property determines the minimum size of panes, in the current object's scale.
