Constructor Details

#initialize(parent_item, name, options = {}, grid = {}, event_handlers = []) ⇒ TkRadioButton

We need to use the tk_variable created by the parent_item So we set it here and skip creation below

def initialize(parent_item, name, options = {}, grid = {}, event_handlers = [])
  @tk_variable = parent_item.tk_variable
  super
end

Instance Method Details

#apply_option(option, v, to_item = self.native_item) ⇒ Object

It is unfortunate that native TK radio buttons use ‘value’ to spedify the value for each of them, colliding with the ‘value’ methods for our items with variables. Thus, we need to override the setting of the ‘value’ option to revert it to the default functionality
