Ive just been assigned my last 16 week project for university but have stumbled across major slowdown with the GUI element of things. Iam using java swing to create a frame and a menubar (done) but I need to be able to have 2 internal frames, one holding a calendar class, the other holding a 'form'. However for the life of me I cant get an internal frame to work, what am I doing wrong? please help! It would be an amazing start for someone just to modify my code so that it will add an internal frame.
Btw Iam running BlueJ and hence it needs to run inside this program. Iam new to java, approx 4 weeks since I started so please be gentle although at heart Iam a hardcore php'er so I understand about variables, arrays, lists etc
Thanks
Mike

This is my way of doing it; I make one JInternalFrame extension so all
my internal frames looks/behaves basically the same. Then I implement my
internal 'frames' as JPanels that I stuff into the center of my JInternalFrame extension.
Notice that I pass the mainFrames pointer to these panels to facilitate
invokation of methods/classes in the mainFrame from the panels.
Also, the way to hook up menuitems, and responding to them is a bit
simpler here.
If you need to have it all in one file (?) you can just copy the class source
into the java file that contains the static void main method (stack them
above each other),
just remember that only the class containing this main must be declared public.
Thanks, Its only in one file at the moment as tbh I have no idea what Iam doing but rather a hack and slash attempt to just get something working at least. Going to have a play with the code you just sent me to see if I can get any further, many thanks for an amazingly quick reply too.
That new function for handling the internal frames has solved all my problems thanks, Ive left it as 2 class's as I was using 2 class's originally anyway so might as well leave it as it is.
Cheers
Mike
