Prevent drawing object in NinjaScript from being selected on chart

[gbrad]

Hi,

Is there any way to prevent a drawing object that was produced within a script from being selected on a chart?

Thanks,

Hello gbrad,

Thanks for your post.

Yes, you can set the property IgnoresUserInput true for each object.

Example:

Dot myDot = Draw.Dot(this, "myDot1", true, 0, High[0]+ 6 * TickSize, Brushes.Red);
myDot.IgnoresUserInput = true;

Hi,

I would also like to prevent lines (created from Draw.Line) from being selected. I was looking to use IgnoresUserInput for this but it is not available for line objects.

Is there an alternative method to prevent lines from being selected?

Thanks,
gbrad

Your statement is incorrect.

Did you try something like this,

[FONT=Arial]Line myLine = Draw.Line(this, "myLine1", ...);
myLine.IgnoresUserInput = true;[/FONT]

I think you have misunderstood the Draw.Line and/or Line help pages.

Draw.Line returns a reference to a Line Object.

A Line object implements the IDrawingTool interface.

(The words "implements the XYZ interface" are very C-Sharpy geek-like
code words -- do you understand this very technical sentence?)

The property IgnoresUserInput comes from the IDrawingTool interface.

Ergo, IgnoresUserInput is available.

Hint:
Look carefully at the top of the Line webpage, see the link to IDrawingTool?

Hi bltdavid,

Yes, I did exactly what you did, but didn't get the same result. But, the good news is that your post helped in getting this resolved.

By forcing IgnoresUserInput and compiling, these error messages appeared:
'Line' is an ambiguous reference between 'NinjaTrader.Gui.Line' and 'NinjaTrader.NinjaScript.DrawingTools.Line'
Cannot implicitly convert type 'NinjaTrader.Gui.Line' to 'NinjaTrader.NinjaScript.DrawingTools.Line'
'NinjaTrader.Gui.Line' does not contain a definition for 'IgnoresUserInput' and no extension method 'IgnoresUserInput' accepting a first argument of type 'NinjaTrader.Gui.Line' could be found (are you missing a using directive or an assembly reference?)

This piece of code did not work and gave the error messages above:

Line DL = Draw.Line(this, "RangeLine-Max", false, -StartPoint, RefPoint-RangeMax, -(Length+StartPoint), RefPoint-RangeMax, C2, D2, W2, true);
// forced line below...there is no IgnoresUserInput that shows in drop down box (could not get screenshot since selection box closes when trying to capture image).
DL.IgnoresUserInput = true;

Qualifying 'Line' with NinjaTrader.NinjaScript.DrawingTools.Line' resolved the the reference; this code worked:

NinjaTrader.NinjaScript.DrawingTools.Line DL = Draw.Line(this, "RangeLine-Max", false, -StartPoint, RefPoint-RangeMax, -(Length+StartPoint), RefPoint-RangeMax, C2, D2, W2, true);
DL.IgnoresUserInput = true;

By using NinjaTrader.NinjaScript.DrawingTools.Line instead of Line cleared up things.

I just assumed that IgnoresUnserInput was not available for Line since it didn't appear in the drop down box when I was trying to select it. I didn't realize at the time that it may be referencing 'NinjaTrader.Gui.Line' instead of 'NinjaTrader.NinjaScript.DrawingTools'.

Thanks for responding to this post. It helped a lot.
