现在的工作主要是把guichan的控件做封装,移植在Symbian上运行.
Container,继承自widget和deathlistener.Most operations are about widget, each widget need a listener to process the needed events . Deathlisten seems to kill a widget when certain event comes.
So now I need to study the details of widget control and death listener.
Deatglistener is a very simple listener, just listen death event of widget.
widget:1, draw the widget, should set the system graphics, which is a virtual function.
2, process all kinds of event.
