Does NT8 SimpleFont support underline or strikethrough?

[Spiderbird]

Hi there,

In NT8's help guide reference for SimpleFont, it references bold, italics, etc. But not underline or strikethrough. I'm looking at this page:

https://ninjatrader.com/support/helpGuides/nt8/en-us/?simplefont_class.htm

How would I designate a SimpleFont with an underline?
Thanks in advance!

Hello Spiderbird,

I'm not aware that SimpleFont has these properties.

I am happy to submit a feature request on your behalf for the NinjaTrader Development to consider this for a future version of NinjaTrader if you would like.

In the meantime, you could achieve this with custom rendering.

Below is a public link to an example of custom rendering text.

Hi Chelsea,

Thanks for the quick response! I believe there's an existing request from the Beta stage for underline text support for SimpleFont, so no need to send it through as a feature request again.

For the example you posted, I'm looking at the following code:

// create a new TextFormat object using information from the chart labels
SharpDX.DirectWrite.TextFormat textFormat = new SharpDX.DirectWrite.TextFormat(Core.Globals.Direct WriteFactory, chartTextFormat.FontFamilyName, chartTextFormat.FontWeight, chartTextFormat.FontStyle, fontSize);

// calculate the which will be rendered at each plot using it the plot name and its price
string textToRender = "Some text to render";

// calculate the layout of the text to be drawn
SharpDX.DirectWrite.TextLayout textLayout = new SharpDX.DirectWrite.TextLayout(Core.Globals.Direct WriteFactory,
textToRender, textFormat, 300, textFormat.FontSize);

Is this what I should be considering when attempting to underline chart text?

Hello Spiderbird,

Use the .SetUnderline from a TextLayout object and use a TextRange object created with the TextLayout.Metrics.Width.

Below is a public link to a 3rd party website that has an example.

https://csharp.hotexamples.com/examples/SharpDX.DirectWrite/TextLayout/SetUnderline/php-textlayout-setunderline-method-examples.html

As well as public links to the documentation. (Unfortunately the SharpDX wiki is not well maintained and looks pretty bad)

http://sharpdx.org/wiki/class-library-api/directwrite/

https://msdn.microsoft.com/en-us/library/windows/desktop/dd371518.aspx

SharpDX.DirectWrite.TextFormat textFormat = font.ToDirectWriteTextFormat();
SharpDX.DirectWrite.TextLayout textLayout =
new SharpDX.DirectWrite.TextLayout(NinjaTrader.Core.Globals.DirectWriteFactory,
text, textFormat, chartPanel.X + chartPanel.W,
textFormat.FontSize);
SharpDX.Vector2 TextPlotPoint = new System.Windows.Point(pointX, pointY-textLayout.Metrics.Height/2).ToVector2();

float newW = textLayout.Metrics.Width; 
        float newH = textLayout.Metrics.Height;
        SharpDX.RectangleF PLBoundRect = new SharpDX.RectangleF((float)pointX+2, (float)pointY-textLayout.Metrics.Height/2, newW+5, newH+2);
        renderTarget.FillRectangle(PLBoundRect, areaBrush);

SharpDX.DirectWrite.TextRange textRange = new SharpDX.DirectWrite.TextRange(0, (int)textLayout.Metrics.Width);

textLayout.SetUnderline(true, textRange);

renderTarget.DrawTextLayout(TextPlotPoint, textLayout, brush, SharpDX.Direct2D1.DrawTextOptions.NoSnap);
textLayout.Dispose();
textFormat.Dispose();

Wonderful! Thanks for your help Chelsea. I’ll give that a shot.
