[bailuyuan@xxxxxxxx (bailuyuan)]

i want to design a platform just like eclipse,when you 
type a dot (" . ") on the code edit square,then it should 
show a select window,the code edit square is extend from
JEditPane,and the window is extends from JWindow and add 
a Jlist on it ,every time when the window is show ,the 
focus is on it ,and can't use "requestfocus()" to make 
it to on the code edit pane,
    Is there any mistake ?
