this abstract class describes stuff common to any Window on a display
|
|
|
57 |
device. i.e. RootWindow, TopWindows, PopUps and Subwindows.
|
|
|
58 |
That is, they have a viewBackground, cursor etc. and especially events.
|
|
|
59 |
A special feature is the delegate field, which allows key- and button
|
|
|
60 |
events to be stolen from a view.
|
|
|
61 |
If the delegate is non-nil, these events will be sent to it instead.
|
|
|
62 |
So you can change a views behavior even if it was not initially designed
|
|
|
63 |
for it. Also, controller functionality could be simulated using delegates.
|
|

|
