Word wrap issues - SyntaxEditor for WPF Forum

Posted 4 years ago by Dirk Zellerfeld

Version: 19.1.0685

Platform: .NET 3.0 (Core)

Environment: Windows 10 (64-bit)

Open the demo app and launch the full Syntax Editor, enable word wrap and paste this single line into the text area:

40 55 56 57 41 54 41 55 41 56 41 57 48 83 EC 60 ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? 4C 8B F2 4C 8B E9 48 89 54 24 28 45 33 FF 4C 39 79 20 0F 86 D8 00 00 00

You will notice that some lines have huge space area when they shouldn't. Screenshot: https://imgur.com/bdqUvCZ

Hi Dirk,

We call into the WPF TextFormatter engine to format the lines and tell it the maximum view width. Then it uses internal logic to find where breaks occur based on that maximum view width. My guess is that its logic sees the "?" and thinks that's a punctuation associated with the "word" before it ("60"), so it tries to keep those together. Thus the "60" moves to a new line even though since you're showing raw hex here, you'd rather it not do that.

Unfortunately there aren't any hooks that we know of in the WPF TextFormatter engine to alter word wrap behavior.
