documentation

"

    a new launcher, combining old Launchers menu and transcript into

    one view. (you no longer have to move two views around all the time ...).

    Also, this app makes first use of the new compatibility framework;

    you will notice, that this is a subclass of ApplicationModel.

    New applications will no longer be built as subclasses of standardSystemView.

"

!

customization

"

    Of course, it is possible to change the NewLauncher class itself

    as appropriate, however, we suggest you create a subclass (say MyLauncher),

    define it as autoloaded in the patches file, and redefined some methods

    there. That way, your changes are easier to reintroduce in case of

    an ST/X upgrade.

    adding more buttons to the button-panel:

      see the method #buttonPanelSpec;

	it defines a list of selectors and icons, which is used by 

	#setupButtonPanelIn:. 

	There, for each entry, a button with that icon is created, 

	which sends a selector-message to the launcher.

	Add entries to that list, and define appropriate methods.

	For example, to add a button which opens a drawTool,

	change #buttonPanelSpec to:

	buttonPanelSpec

	    ^ #(

		#(startSystemBrowser  'SBrowser32x32.xbm')

		#(startFileBrowser    'FBrowser32x32.xbm')

		#(nil nil)

		#(startChangesBrowser 'CBrowser32x32.xbm')

		#(nil nil)

		#(nil nil)

		#(startDrawTool       'DrawTool.xbm')

	     )

	the panel adjusts its height as appropriate - you may want to

	create new (small) icons for a good look.

    adding an entry to a menu:

	see the #setupMenu method; either add another top-menu, or

	add entries to an existing menu.
