*Goal
We are trying to implement an “Orphans” prevention system for unreal, since it is a big deal for our product.

Issue
The system has already been implemented in Unity, where we created a custom extension of the TMP component and had the needed data available in the TextInfo class.

However, for Unreal the component doesn’t seem to expose such data. We would have to compute it ourselves taking into account all the component and widget parameters.

References
We are trying to implement something similar to the “text-wrap: pretty” in CSS.

Questions

  • Are we missing a way were we can get the “TextInfo” data similar to Unity?
  • If not, what is the most advisable way to perform the computation to generate it ourselves?

Thanks.

I just found the variable I’m looking for (LineViews). Shoutouts to this great article

Unfortunatelly, is private on several levels, and since I don’t know how to work around that without modificating the source code, which is not an option, I’ll have to compute the value myself.

The path to get to the variable from the “TextBlock” is the following, for anywone willing to modify the engine:

For TextBlock:

TextBlock->MyTextBlock->TextLayoutCache->TextLayout->LineViews

For RichTextBlock:

RichTextBlock->MyRichTextBlock->TextLayoutCache->TextLayout->LineViews
