In Need of some Window_Command & Window_Selectable Help

I'm trying to set up a (horizontal) command window where, upon pressing either left or right, the command window refreshes and draws a different picture. However, I cannot seem to get the command window to refresh upon key input.

Any help or suggestions would be MUCH appreciated. Thanks!

Well, I would suggest making your classes subclasses of Window_Selectable or Window_Command rather than Window_Base. That way you'll have all of the methods you need and only have to change a few things. For the refresh, you might just want to keep track of the old index with a variable. Say, initialize the variable @old_index in the initialize method. Then you can use this check to see if index has changed:

Code: [Select]

if @old_index != self.index
  refresh
  @old_index = self.index
end

in the update method.
