Draw listener

[zooinek]

Hello

I need to ask you... is there any listener interface or any method/function in NinjaTrader which is invoke/called everytime when user draw new object into chart?

I am programming simple indicator, but I need that indicator will re-calculate everytime, when user draw something into chart.

Imagine this:
User choose any candle and click F7 (draw blue line on the selected candle) and right after the indicator should do some calculations - so the indicator needs to know when user draw the blue line (F7 button)

Do you understand what I mean?

Thank you

zooinek, there's unfortunately no event on drawing object changes, you would need to loop through the collection of objects on each tick to be close to the point where the user finished adjusting it - http://www.ninjatrader.com/support/h...drawobject.htm

Hi

How do I determine if a draw object is finished being adjusted?

I'm writing a strategy to snap a manually drawn rectangle to the candles enclosed within it. It runs every tick as explained in the post below. However, if a tick arrives before I've drawn or adjusted the rectangle, it snaps while I'm dragging it. I would like to skip processing it until the adjusting is complete.

If I could detect whether or not the rectangle is selected, then I could skip processing it until it is no longer selected. Is that possible?

Cheers
Tony

Hello Tony,

This is not a supported way to detect the selected state of a drawing object.

I am also not aware of any unsupported way to achieve this as well.

However, for NinjaTrader 8, when looping through the DrawObjects, there is an IDrawingTool.IsSelected state that can be checked.
