# We put a lot of work into making our window for the tweener.
# But what if we want to make another window? Do we have to write everything again?

# Fortunately Python classes support inheritance
# Just like your inherit your good looks from your parents, Python classes can inherit methods and attributes from their parents

# So we first make a Base Window that we can reuse.
# This will have just the bare functionality to make a window
class BaseWindow(object):
    windowName = "BaseWindow"

    def show(self):
        if cmds.window(self.windowName, query=True, exists=True):
            self.close()

        cmds.window(self.windowName)
        self.buildUI()
        cmds.showWindow()

    def buildUI(self):
        # This is a placeholder method
        pass

    # Again, the *args variable means that we don't know how many arguments we will receive so lets put them all inside this argument called args
    def reset(self, *args):
        # This is a placeholder method
        pass

    def close(self, *args):
        cmds.deleteUI(self.windowName)


# For our tweener UI, we inherit from our BaseWindow
# Just like our BaseWindow inherits from the Python object, our TweenerWindow inherits from BaseWindow
# This means that it will get all the attributes and methods that the Base Window has
class TweenerWindow(BaseWindow):
    # The Base Window has a windowName attribute
    # By defining it here, we are overriding it.
    # Just like you may have different taste in music than your parents golden oldies, a child class can have
    #       different attributes than its parent
    windowName = "TweenerWindow"

    # Similarly we redefine the buildUI method.
    # When buildUI is called in any methods from BaseWindow, it will know to refer to our overriden variable here

        cmds.setParent(column)
        cmds.button(label="Close", command=self.close)

    # And again, we just need to override the reset method
    # We don't need to define the close, or show methods because it gets those from BaseWindow
    def reset(self, *arg):
        cmds.floatSlider(self.slider, edit=True, value=50)


# Now that we have our tweener working, we can work on our Gear Creator Window
# Just like the Tweener we inherit from BaseWindow which gives us all its attributes and methods

        # If there is a gear already made, then we will set the slider to edit it
