Hi.
I'm trying to spruce up my user interface to have menuitem interaction.
I'm using the method below to take care of mouse actions on the menubar
of the frame. This works fine by itself. It kills the window. However,
when I try to add the second code segment below into the same class, the
window closes if I click the "close window" button on the window, but my
menu items fail to function. What am I doing wrong here?
And Sami Shaio, if and when you read this, my congratulations for
producing a wonderful book. "Hooked on Java" really does the job.
Reply by e-mail to: tan@cdr.stanford.edu is requested.
*************** 1st code segment ***************
public boolean action(Event evt, Object obj) {
if (evt.target instanceof MenuItem) {
String label = (String)obj;
if (label.equals(QUIT)){
this.dispose();
System.exit(0);
}
etc. -------- etc.
*************** 2nd code segment ***************
public boolean handleEvent(Event evt) {
switch(evt.id){
case Event.WINDOW_DESTROY:{
this.dispose();
System.exit(0);
return true;
}
default:
return false;
}
}
