Intercept keyboard event and trigger

[1001111]

Hi,

after trying to implement something for a long time and failing to do so, unfortunately I have to ask for help.
I hope somone can help me.

My goal is to create a script to move the chart from the program.
Since I did not find anything in the documentation, I would like to use C# Event, the
Left and right arrow triggers.

protected override void OnStateChange()
{
    if (State == State.DataLoaded)
    {
        this.ChartPanel.KeyDown += new System.Windows.Input.KeyEventHandler(OnKeyDown);          
    }
    else if (State == State.Terminated)
    {
        this.ChartPanel.KeyDown -= OnKeyDown;          
    }
}

public void OnKeyDown(object sender, System.Windows.Input.KeyEventArgs e)
{   
    // detect Key (23 Left) and (25 Right)?
    Print("Down");     
}

example, not working


Unfortunately, after 8 hours of programming, I am not getting anywhere.
Can someone help me and tell me:

A, how to intercept the keyboard event?
B. That can act as a trigger?

Hello,

You can find a sample of using key events in the linked post below. As this is not NinjaScript specific you won't find much information about using WPF key events here on the forum or in the help guide. The best bet is to look for WPF samples online for specific concepts like this and then apply them in NinjaTrader.

Because NinjaTrader is a WPF application that already has key events on the objects you are using, the PreviewKey events are generally needed to intercept key events. This is also not NinjaTrader specific but is standard with WPF design.

I look forward to being of further assistance.
