We are flipping back and forth between 1.3.1 and 1.4.1 right now. We wanted
to handle a change from requestFocus used in 1.3.1 and prior to
requestFocusInWindow. We have a number of our own classes that extend Swing
Components so we thought we could over-ride requestFocusInWIndow so that it
would work whether we compiled in 1.3.1 or 1.4.1.
We though we might do the following:
public boolean requestFocusInWindow(){
if (IS_JRE_1_3){
requestFocus();
return false;
}
try{
java.lang.reflect.Method requestFocusInWindow =
super.getClass().getMethod("requestFocusInWindow",null);
Object result = requestFocusInWindow.invoke((JButton)this,null); //
.invoke(super,null); doesn't compile
return ((Boolean)result).booleanValue();
}
catch(Exception e){
return false;
}
}
My question is will the invoke statement actually invoke the
JButton.requestFocusInWindow or will it recurse into this sub-class method?
