Some Tk operations don't normally pass through Tkinter. For example, if a character is inserted into a Text widget by pressing a key, a default Tk binding to the widget's 'insert' operation is activated, and the Tk library processes the insert without calling back into Tkinter. Although a binding to <Key> could be made via Tkinter, what we really want to do is to hook the Tk 'insert' operation itself. When a widget is instantiated, a Tcl command is created whose name is the same as the pathname widget._w. This command is used to invoke the various widget operations, e.g. insert (for a Text widget). We are going to hook this command and provide a facility ('register') to intercept the widget operation. In IDLE, the function being registered provides access to the top of a Percolator chain. At the bottom of the chain is a call to the original Tk widget operation. c C se i | _ | | _ | j | _ } | j } | d | _ | j d | | j � | j | | j � d S( Nt _origt rename( t _operationst widgett tkt _wt origt callt createcommandt dispatch( t selfR R t w( ( s0 /usr/lib64/python2.7/idlelib/WidgetRedirector.pyt __init__ s c C s d | j j j | j j f S( Ns WidgetRedirector(%s<%s>)( R t __class__t __name__R ( R ( ( s0 /usr/lib64/python2.7/idlelib/WidgetRedirector.pyt __repr__& s c C s{ x$ t | j � D] } | j | � q W| j } | ` | j } | ` | j } | j } | j | � | j d | | � d S( NR ( t listR t unregisterR R R R t deletecommandR ( R t operationR R R R ( ( s0 /usr/lib64/python2.7/idlelib/WidgetRedirector.pyt close* s c C s- | | j | <t | j | | � t | | � S( N( R t setattrR t OriginalCommand( R R t function( ( s0 /usr/lib64/python2.7/idlelib/WidgetRedirector.pyt register5 s c C sW | | j k rO | j | } | j | =t | j | � rK t | j | � n | Sd Sd S( N( R t hasattrR t delattrt None( R R R ( ( s0 /usr/lib64/python2.7/idlelib/WidgetRedirector.pyR : s c G s\ | j j | � } y1 | r% | | � S| j j | j | f | � SWn t k rW d SXd S( s Callback from Tcl which runs when the widget is referenced. If an operation has been registered in self._operations, apply the associated function to the args passed into Tcl. Otherwise, pass the operation through to Tk via the original Tcl function. Note that if a registered function is called, the operation is not passed through to Tk. Apply the function returned by self.register() to *args to accomplish that.
