NAME

       NewCompCmd, PrintCmd, QuitCmd, RevertCmd, SaveCompCmd, SaveCompAsCmd, ViewCompCmd - catalog-oriented commands

SYNOPSIS

       #include <Unidraw/Commands/catcmds.h>

DESCRIPTION

       The Unidraw library predefines a set of non-interpretive commands that let a user specify components to open, view, and save, plus commands
       for generating a PostScript external representation and for quitting the application.  NewCompCmd re-initializes its editor's component	to
       let  the  user  start editing afresh.  If the existing component is modified, NewCompCmd prompts the user to save it.  PrintCmd generates a
       PostScriptView of the editor's component and lets the user send it to a file or to a printer.  QuitCmd quits the application, prompting the
       user  to  save  modified  components.   RevertCmd  lets the user re-open the current component, discarding changes since it was last saved.
       SaveCompAsCmd lets the user save a component under a particular name, while SaveCompCmd saves a component named previously.  Finally, View-
       CompCmd lets the user specify another component to view in its editor.

NEWCOMPCMD PUBLIC OPERATIONS

       NewCompCmd(ControlInfo*, Component* prototype = nil)
       NewCompCmd(Editor* = nil, Component* = nil)
	      Create a new NewCompCmd instance, optionally supplying a prototype component.  When executed, NewCompCmd will make its editor edit a
	      copy of the prototype.  The editor's original component will be deleted if no other editor refers to it.

       virtual boolean Reversible()
	      NewCompCmd is not reversible.

       Component* GetPrototype()
	      Return the prototype component specified in the constructor.

PRINTCMD PUBLIC OPERATIONS

       PrintCmd(ControlInfo*, PrintDialog* = nil)
       PrintCmd(Editor* = nil, PrintDialog* = nil)
	      Create a new PrintCmd instance, optionally supplying the PrintDialog to display when executed.

       virtual boolean Reversible()
	      PrintCmd is not reversible.

PRINTCMD PROTECTED OPERATIONS

       void print(const char* print_cmd, const char* file)
	      Concatenates print_cmd and file and calls system(3) on the result.

QUITCMD PUBLIC OPERATIONS

       QuitCmd(ControlInfo*)
       QuitCmd(Editor* = nil)
	      Create a new QuitCmd instance.

       virtual boolean Reversible()
	      QuitCmd is not reversible.

REVERTCMD PUBLIC OPERATIONS

       RevertCmd(ControlInfo*)
       RevertCmd(Editor* = nil)
	      Create a new RevertCmd instance.

       virtual boolean Reversible()
	      RevertCmd is not reversible.

SAVECOMPCMD PUBLIC OPERATIONS

       SaveCompCmd(ControlInfo*)
       SaveCompCmd(Editor* = nil)
	      Create a new SaveCompCmd instance.

       virtual boolean Reversible()
	      SaveCompCmd is not reversible.

SAVECOMPASCMD PUBLIC OPERATIONS

       SaveCompAsCmd(ControlInfo*, FileChooser* = nil)
       SaveCompAsCmd(Editor* = nil, FileChooser* = nil)
	      Create a new SaveCompAsCmd instance, optionally supplying the FileChooser that will prompt the user to name the component.

       virtual boolean Reversible()
	      SaveCompAsCmd is not reversible.

VIEWCOMPCMD PUBLIC OPERATIONS

       ViewCompCmd(ControlInfo*, FileChooser* = nil)
       ViewCompCmd(Editor* = nil, FileChooser* = nil)
	      Create a new ViewCompCmd instance, optionally supplying the FileChooser that will prompt the user to specify the component to  view.
	      After the new component is opened successfully, the editor's original component will be deleted if no other editor refers to it.

       virtual boolean Reversible()
	      ViewCompCmd is not reversible.
