Instance Method Details

#associated_subscribers ⇒ Object

(hopefully temporary) method – when this window is closed, all widgets containsed within it that are subscribers to application events should also be unsubscribed so their notify method isn’t later called - which causes a crash in wxruby 0.6.0

# File 'lib/weft/wxgui/inspectors.rb', line 139

def associated_subscribers()
  [ @drop_down ]
end

#get_current_category ⇒ Object

the current category active in this window

def get_current_category()
  if curr = @drop_down.current_category
    return curr
  else
    return nil
  end
end

#on_activate(e) ⇒ Object

this method should update the code combo box - this is done by the MDI Parent. But - the ActivateEvent class is not currently available in wxruby 0.6.0, so there’s no way to distinguish an activate from a deactivate

end

#on_key_down(evt) ⇒ Object

implements keyboard shortcuts for this window - these are activated by interaction with the text-box. currently, 

CTRL-m is mapped to "Mark" 
CTRL-, is mapped to "Unmark"
CTRL-f is mapped to "Start find"
