    Detecting key press event in selected DrawingTool

    Hi,
    Is there any way to detect that the user pressed a key when a custom DrawingTool on a chart was selected? I would like to detect it within the custom DrawingTool.

    Thank you.

    Hello CycleArt,

    Thanks for your inquiry.

    Within the GetCursor() method, you could check the DrawingState of the Drawing object to see if it is selected.

    As a rough example, you may consider the following:
    Code:
    private bool selected = false;
    private bool doOnce = true;
    
    public override Cursor GetCursor(ChartControl chartControl, ChartPanel chartPanel, ChartScale chartScale, Point point)
    {
    	if (DrawingState == DrawingState.Normal)
    		selected = true;
    	else
    	{
    		selected  = false;
    		doOnce = true;
    	}
    	
    	if(selected && doOnce)
    	{			
    		Print(DrawingState.ToString());
    		doOnce = false;
    	}
    }
    Detecting button presses can be done through C# by using System.Windows.Input.Keyboard.IsKeyDown. This concept is external to NinjaScript and would be referenced on the MSDN documentation page for usage.

    System.Windows.Input.Keyboard.IsKeyDown - https://msdn.microsoft.com/en-us/lib...v=vs.110).aspx

    Publicly available documentation on GetCursor() can be found here - https://ninjatrader.com/support/help.../getcursor.htm

    Please let us know if you have any additional questions.
