Swing ; Panels
Hello,
A friend has designed a graphic interface
with a tabbedpane
I want to insert a button in one of the tabs
JButton hej =new JButton("Min hejknapp") ;
JLabel hejsan =new JLabel() ;
hejsan.add(hej) ;
calendarPanel.add(hejsan) ;
But it's not visible
Can you see why? :)
Kind regards// jR
btw here's the rest of the code
