Add Images into the Java Interfaces Using jpl_new or jpl_call

[Ting Tze Sheng]

Hi, I was developing an expert system in swi prolog with java interface, the main problem is that i don't know how to insert images into the interfaces, I have tried by converting the java code into the prolog with jpl, it shows no error, but the panel does not show the image.

interface:-

        jpl_new('javax.swing.JFrame', ['Expert System'], F),

jpl_new('javax.swing.JPanel',[],Pan),

jpl_new('javax.swing.JLabel',[],LBL),

jpl_new('javax.swing.ImageIcon', ['C:/Users/Ryan/Deskstop/cat.png'], Pic),

jpl_call(LBL, setIcon, [Pic], _),

jpl_call(Pan,add,[LBL],_),

jpl_call(F,add,[Pan],_),

jpl_call(F, setLocation, [400,300], _),

jpl_call(F, setSize, [400,300], _),

jpl_call(F, setVisible, [@(true)], _),

jpl_call(F, toFront, [], _).

which is equivalent in java code such as:

  JLabel lblwelcomeToExpert = new JLabel("====Welcome to Expert System====");

lblwelcomeToExpert.setBounds(95, 13, 232, 81);

icon = new ImageIcon("C:/Users/Ryan/Desktop/cat.png");

lblwelcomeToExpert.setIcon(icon);

panel.add(lblwelcomeToExpert);

I have tried alternative with by calling JOptionPane.showInputDialog in prolog(same piece of code on above):

         jpl_call('javax.swing.JOptionPane', showInputDialog, [F,'Hi. How are you? First of all tell me your name please','Expert System', 'INFORMATION_MESSAGE', Pic, null,''], N),

which should be the same as:

JOptionPane.showInputDialog(frame, "input for testing","hello", JOptionPane.INFORMATION_MESSAGE, icon, null, "");

Please show me the correct syntax, i've searched on google but there is no good examples for me to refer. Sorry for the bad English, not my primary language.
