Dukascopy Support Board • View topic - Strategy Adds Graphic Objects, Workspace Chart Tree View is expanded

JForex platform LIVE FXDD ver. 2.21.11 JForex API ver. 2.7.5.2

This is a behavior which has existed for many months; I just haven't reported it; NOT a new behavior.

Attached screenshot shows that the Tree View of the Chart is forced to expand. If I collapse it, then it continues to expand itself. I would like the tree view to close, and not to auto-expand.

A Strategy module is placing the horizontal and vertical line objects on the chart, and this appears to have the side-effect of causing the Chart's Workspace Tree View to auto-expand, even if I collapse it, it immediately reverts to expanded for the chart marked on the screenshot.

The Strategy module code does delete and replace charting objects, and here is a small section of the code (not necessarily elegant code...). The code does "remove" the object and then add it again, which I realize is not necessarily most efficient :

        // draw a label
        final ILabelChartObject myDrawLabel(final IChart chart,final String key, IChart.Type type, long time, double price) {
            IChartObject existing = chart.get(key);
            if (existing!=null) {
                chart.remove(existing); // otherwise, they accumulate?
            }
            IChartObjectFactory factory = chart.getChartObjectFactory();
            ILabelChartObject co = factory.createLabel(key, time, price);
            //IChartObject co = chart.draw(key, IChart.Type.LABEL, time, price);
            return co;
        }
        
        // draw a horizontal line
        final IHorizontalLineChartObject myDrawHorizontalLine(final IChart chart,final String key, IChart.Type type, long time, double price) {
            IChartObject existing = chart.get(key);
            if (existing!=null) {
                chart.remove(existing); // otherwise, they accumulate?
            }
            IChartObjectFactory factory = chart.getChartObjectFactory();
            IHorizontalLineChartObject co = factory.createHorizontalLine(key, price);
            return co;
        }
        
        
        // draw a dashed horizontal line
        final IHorizontalLineChartObject myDrawDashedHorizontalLine(final IChart chart,final String key, IChart.Type type, long time, double price) {
            IChartObject existing = chart.get(key);
            if (existing!=null) {
                chart.remove(existing); // otherwise, they accumulate?
            }
            IChartObjectFactory factory = chart.getChartObjectFactory();
            IHorizontalLineChartObject co = factory.createHorizontalLine(key, price);
            co.setStroke(dashedStroke);
            return co;
        }
        
/// ................. example of calling these routines from within onTick handler

                    // up 1
                    chartObject = myDrawLabel(chart,"PipsUp1", IChart.Type.LABEL, nowTime + timeInterval, tickRef+pipValue); 
                    chartObject.setColor(Color.yellow); 
                    chartObject.setText("+1 ___", new Font(Font.SANS_SERIF, Font.PLAIN, 14)); 
                    chart.addToMainChart(chartObject);
                    if (useLines) {
                    chartObject = myDrawDashedHorizontalLine(chart,"PipsUp1Line", IChart.Type.HLINE, nowTime, tickRef+pipValue); 
                    chartObject.setColor(Color.GRAY); 
                    chart.addToMainChart(chartObject);
                    }
                    

                    // up 2
                    chartObject = myDrawLabel(chart,"PipsUp2", IChart.Type.LABEL, nowTime + timeInterval, tickRef+2.0*pipValue); 
                    chartObject.setColor(Color.yellow); 
                    chartObject.setText("+2 ___", new Font(Font.SANS_SERIF, Font.PLAIN, 14)); 
                    chart.addToMainChart(chartObject);
                    if (useLines) {
                    chartObject = myDrawDashedHorizontalLine(chart,"PipsUp2Line", IChart.Type.HLINE, nowTime, tickRef+2.0*pipValue); 
                    chartObject.setColor(Color.GRAY); 
                    chart.addToMainChart(chartObject);
                    }

Thanks for looking into this NON-urgent issue.
