# GTInspector Introduction script

- we start with a script that creates an OrderedDictionary (hashtable)
     - present each object that gets added to the dictionary: date, color, morph (graphical component)
- select the code and choose 'Do it and go' from the context menu.
	- explain that we select the code and execute it in place
	- the dictionary object is opened in a new pane to the right

- emphasize that the state view is useful for understanding how the object is implemented
	- explore the implementation of the dictionary:
		- sorted keys are stored in an array (expand orderedKeys)
		- actual values are stored in a simple dictionary (expand dictionary)

- this view is especially useful for the person implementing a dictionary/hashtable
- if all we want is to quickly browse through the content of a dictionary object a much better solution is to display its content as a table
- the Items view gives a quick way to scan through the elements;
	- switch to the items view

- next I want to inspect these objects in more details
     - I can select an object and it is opened in another pane to the right.

- select the Color object
	- the color object has a natural representation 
	- show the Color view

- select the date object
	- the state view shows how it is implemented
		- expand start
	- the Details view shows more specific data about this date
	- the Calendar view simply shows a calendar

- select the morph object (HSVColorSelectionMorph)
	- the state view shows how it's implemented
	- most of the time I also want to see how it looks like
		- switch to the Morph view
	- morphs form a containment structure
		- let's see how we can find the morph representing the two arrows
	- switch to the State view and start expanding the submorphs arrays
		- it's quite difficult
	- show the Submorphs view
		- select any submorph and in the new pane switch to the Morph view
		- we get a browser to visually look for a morph
		- use it to find the two arrows

- briefly introduce the navigation mechanism
	- every circle at the bottom is a previously inspected object
	- on hover we get a preview
	- on click the inspector navigates to that object
	- we can also scroll
	- we can also increase/reduce the number of visible objects
