1.50.2 BLOX.BWindow: accessing

callback
Answer a DirectedMessage that is sent to verify whether the receiver must be destroyed when the user asks to unmap it.


callback: aReceiver message: aSymbol
Set up so that aReceiver is sent the aSymbol message (the name of a zero- or one-argument selector) when the user asks to unmap the receiver. If the method accepts an argument, the receiver is passed.

If the method returns true, the window and its children are destroyed (which is the default action, taken if no callback is set up). If the method returns false, the window is left in place.


invokeCallback
Generate a synthetic callback, destroying the window if no callback was set up or if the callback method answers true.
