Calling parent class methods from a sub class
Basically here is the gist of my problem: I've created a GUI thats a Calendar
to store to do list items for each day of the month. My main class, myCalendar,
contains a method called addItem. This method takes an object I've created(a
to do list Item) and stores it into a Vector. Later I call a method called
printUnsorted( from within the myCalendar class), which should access each
element of the Vector and then output the element to the screen. I have
a subclass called multiBox which extends from the myCalendar class. I extend
it so that it can access myCalendar's addItem method. Basically this subclass
is declared within myCalendar, then myCalendar sets it to visible after a
day on the calendar has been double clicked. multiBox is a frame, just like
myCalendar is. The user enters all the fields of an object( the to do list
Item ) and then clicks done. When done is clicked, multiBox calls myCalendar's
addItem with this new object as the passed in parameter. The problem here
is this: When inside multiBox I do get this object. I can output it and
everything. After I call addItem, and I'm inside addItem's body, the object
is still there. Then I add it to the Vector. I can than still access that
item in the Vector and output it to the screen so I know its still there,
but when myCalendar calls the printUnsorted method, and then prints out the
Vector, the Item is no longer there. In fact the Vector has a size of 0.
I don't know if it is because of the multiple frames, or how I'm making
multiBox a subclass of myCalendar, but I can't seem to get it to work. I
would so appreciate any help, and I can even send you the code if need be.
Thanks so much,
Nate
