Accessing custom drawing object properties

[Matt Skinner]

Hello, is there any way to access and change properties of a custom drawing object such as https://ninjatraderecosystem.com/use...-drawing-tool/ this one. It is overloaded, so I can easily access it, but the author says that in order to change the Text label, the template needs to be changed. Can I access, create and edit a template somehow using code? If not, is it possible to access the object using it's tag like I would any other (picture).

Hello Matt Skinner,

Thank you for your post.

To clarify, are you trying to change the Text of the drawing object through code? Or are you trying to edit a drawing object template through code?

Are you actually using the Labeled Lines drawing tool you linked, or another script? If you are using another script, I would ask the developer for clarity as whether or not you can access a custom tool's properties / edit them depends wholly on how the developer coded the script.

You can access a drawing object using its tag through code using the DrawObjects collection. The Help Guide page below has sample code demonstrating:

Please let us know if you need further assistance.

Yes, I am actually using the Labeled Lines drawing tool that I linked. It is possible with this one.

Hello Matt Skinner,

Unfortunately it is not possible to edit a drawing object template through code - however, you can access the tag through the DrawObjects collection as previously mentioned.

Please let us know if you have any further questions.

I undestand that It is possible to access the object, but in my case the object is this( https://ninjatraderecosystem.com/use...-drawing-tool/) custom addon drawing tool. When I use this code (picture).

Error gets shown that drawObject doesn't have any property called "Text". But on the next picture you can clearly see that a property like that exists, how would I go about accessing it? If it is even possible in this case, you mentioned that the creator can decide if properties can be accessed. How can I check that? Thank you for your time!

Hello Matt Skinner,

You would use the DisplayText property.

foreach (DrawingTool draw in DrawObjects.ToList())
{
if (draw is DrawingTools.LabeledHorizontalLine)
{
DrawingTools.LabeledHorizontalLine myLine = draw as DrawingTools.LabeledHorizontalLine;
Print(myLine.DisplayText);
}
}

Please note that this will only print out the text the user typed, and not the price being rendered in text as this isn't exposed.

Thank you so much. I did it.
