Hi everybody,
I'm creating a custom trading platform based on the Jforex API and I need help.
My problem is that I have a ComboBox where I put all the crosses (EUR/USD, USD/CHF...), and when choosing another cross (USD/CHF for example) the loaded chart is the wrong one (GBP/USD for my case).
I don't know if there's a problem with my feedDescriptor or another thing... Do a I have to handle this with the ChartController or the ChartPresentationManager?

I'll be glad to hear your suggestions.
Thank you very much !

Hi,

There are some examples can be found on the wiki about how to do this and that in the ITesterClient interface.
For example the GUIModeChartTypes.java contains a way to implement a ComboBox based instrument switch.

If you have already seen these examples, and still have some issue, I suggest to show us your code, so we can assists further.

Good luck.

Hi and thank you for your reply.
I already checked the GUIModeChartTypes.java and i haven't figured it out yet.
I created a ComboBox and here is the ItemListener code (that's where my problem is located I think)

jCrossComboBox = new JComboBox<Instrument>();
        for(int i=0;i<instArr.length;i++){
        jCrossComboBox.addItem(instArr[i]);
        }
        
        jCrossComboBox.addItemListener(new ItemListener() {
         
         @SuppressWarnings("deprecation")
         @Override
         public void itemStateChanged(ItemEvent e) {
             if (e.getStateChange() == ItemEvent.SELECTED) {
            Instrument instrument = (Instrument) jCrossComboBox.getSelectedItem();
            System.out.println("Instrument choisi" + instrument);
              IChart chart = chartPanels.keySet().iterator().next();
              System.out.println(chart.toString());
            IFeedDescriptor feedDescriptor = chart.getFeedDescriptor();
            System.out.println("Le Feed est " + feedDescriptor.toString());
            feedDescriptor.setInstrument(instrument);
            
            getChartController().setFeedDescriptor(feedDescriptor);
            
             }
         }
      });

Please provide a full example program which demonstrates the problem.
