Is there a way to suppress the tooltips, or popup labels like "Label" or "Horizontal line"
when the mouse hovers over the chart items?
I could iterate through all IChartObjects, I guess, and set the tooltip to null or nothing...
But is there a way to disable them for a chart?
Thanks!

Hey, somebody out there knows the answer to my question. Pleeeez.

(Just the old-fashioned API...)

HyperScalper

No.
That is the way to achieve this.

For my ILabelChartObject items, I am able to modify the tooltip using setTooltip(String).

Also successful for IVerticalLineChartObject items.

However, for IHorizontalLineChartObject items, it seems even though I modify the tooltip string, they continue to display the generic "Horizontal Line" where the mouse hovers over them, which looks like a bug to me.

We can't replicate this please provide your case. We used the following strategy:

package jforex.charts;

import com.dukascopy.api.*;
import com.dukascopy.api.drawings.IChartObjectFactory;

public class TooltipTest implements IStrategy {

    private IChart chart;
    private IHistory history;
    private IConsole console;
    
    @Configurable("")
    public Instrument instrument = Instrument.EURUSD;
    @Configurable("line count")
    public int lineCount = 10;    
    
    
    @Override
    public void onStart(IContext context) throws JFException {
        this.chart = context.getChart(instrument);
        this.history = context.getHistory();
        this.console = context.getConsole();
        
        if(chart == null){
            console.getErr().println("No chart opened for " + instrument);
            return;
        }
        IChartObjectFactory factory = chart.getChartObjectFactory();
        double basePrice = history.getLastTick(instrument).getBid();
        
        IChartObject object;
        for(int i=0; i< lineCount; i++){
            //hline every 2 pips
            object = factory.createHorizontalLine("h"+i, basePrice + instrument.getPipValue() * 2 * i);
            object.setTooltip("Hline " + i);
            chart.add(object);
            //vline every 2 feed elements
            object = factory.createVerticalLine("v"+i, history.getFeedData(chart.getFeedDescriptor(), i * 2).getTime());
            object.setTooltip("Vline " + i);
            chart.add(object);
        }  
    }

    @Override
    public void onTick(Instrument instrument, ITick tick) throws JFException {    }

    @Override
    public void onBar(Instrument instrument, Period period, IBar askBar, IBar bidBar) throws JFException {}

    @Override
    public void onMessage(IMessage message) throws JFException {}

    @Override
    public void onAccount(IAccount account) throws JFException {}

    @Override
    public void onStop() throws JFException {
        chart.removeAll();
    }

}

I will check. Vertical line tooltip is OK for me, it is just Horizontal which has the issue.

Thank you for investigating this, I'll get back with some more detail.

This is standalone client with standalone charting v 2.7.9 API.

OK, seems an error on my side.

setTooltip("") was not eliminating the tooltip.
setTooltip("*") does replace the tooltip on horizontal line.

So, it seems that an empty string is ignored, but a non-empty string works.

Problem resolved for me.

Thanks for your help !!
