ShartStyle changed event.

[fx.practic]

Hello.

Can
the indicator be notified about ChartStyle changing?
Something like OnChartStyleChanged event, may be?
OnStateChange() of indicator not triggered at all while ChartStyle changed.

Thank You.

Hello fx.practic,

There isn't anything documented for this.

But you might be able to apply a property changed event for the custom chart style event.

Here is a link to a post you may find helpful.

After reviewing thread You pointed I found one only related snippet:

foreach(ChartScale cs in cp.Scales)
{
      cs.ChartObjects.CollectionChanged += myCollectionChanged;                        
} 

Does NT have same event related for ChartStyle changing, say BarColors.Chanded, or ChartScale.Changed?

Hello fx.practic,

Hmm, this doesn't seem to be the actual script I was thinking it was.

I wasn't even able to find the script from Matthew with the PropertyChangedEventHandler on the forums..

I was able to find the script on our internal shared server and I'm happy to share it.

The undocumented (unsupported) relevant code is:

public class SamplePropertyChangedDrawingTool : Line, INotifyPropertyChanged


// this event will be subscribed from the indicator and updated anytime those properties call DoPropertyChanged
public event PropertyChangedEventHandler PropertyChanged;

// send the property name to the event so you can detect which property changed
protected void DoPropertyChanged(string propertyName)
{
    PropertyChangedEvent(new PropertyChangedEventArgs(propertyName));
}

// propagate drawing tools PropertyChanged to the indicator
protected void PropertyChangedEvent(PropertyChangedEventArgs e)
{
    if (PropertyChanged != null)
        PropertyChanged(this, e);
}
