Dobrý den,
netbeans IDE jsem si vytvořil JFrame form a JPanel form (pravý klik na Pacakge/new/JFrame form ..... obdobně i JPanel form), mno a teď mám obrovský problém "JAK VLOŽIT JPANEL DO JFRAME FORMU A ZOBRAZIT????", zkoušel jsem spoustu variant ale nic mi nefakčilo. Googlil jsem, ale asi špatně ..... Můžete mi prosím poradit ?
