Dynamic Trade Interface

A high-performance and customizable trade interface originally inspired by Trade UI Revised.
Written from scratch to not only avoid the biggest performance hits of the vanilla UI but to also allow for other mods to easily extend it with additional columns.

Can be safely added or removed at any time during a playthrough, since it doesn't add any game content.
Does not replace the vanilla trade window. Instead you can choose in the mod options whether to open this or vanilla one by default, the other one can be accessed by holding down ctrl as the window opens.

The changelog can be found under the Change Notes tab.

• Due to how Rimworld's UI system works, controls will lose focus if any other control is made visible or invisible ahead of it. Generally to the left and up.
  This means that for example, putting the buttons to the left of the input counter boxes will cause them to unfocus when buttons change.
  There is now an option that can be enabled in the mod settings that attempts to compensate for this, by automatically refocusing the control whenever the focus is lost from changing interface. Often the escape button can be used to close windows that appear unreponsive.

XSD files are bundled with the mod describing how to define a TradeColumnDef.
Based on a number of method handlers, column behaviour can be easily referenced in C#.
Because it doesn't use any custom typings, it can all be defined without any need for assembly references or otherwise.

The following C# handlers can be defined:

• static void PostOpen(IEnumerable<Tradeable> rows, Transactor transactor)
  Called twice after the window is opened initially, for Colony and Trader respectively. Useful for preparing cache.
  
• static void PostClosed(IEnumerable<Tradeable> rows, Transactor transactor)
  Called twice after the window is closed, for Colony and Trader respectively. Useful for cleaning up cache.
  
• static void Draw(ref Rect cell, Tradeable row, Transactor transactor, ref bool refresh)
  Called every frame for each row to draw column cells.
  
• static Func<Tradeable, IComparable> OrderbyValue(Transactor transactor)
  Called once when the table is prepared to provide a sorting value selection function.

Experiencing an issue?

1. First check that it is actually caused by this mod; Either remove it temporarily, (can be added or removed any time!) or hold ctrl while trade opens to open the original vanilla trade window and check if isssue is also present there.
   
2. If the issue is still there, then it isn't related to this mod and should be reported somewhere else.
   
3. If you don't experience the issue with or in vanilla, then do provide a description of what you are trying to do, and what the problem you are experiencing is. The more details the better!
   
4. If the issue causes an error in the log, then use Hugslib log publisher to provide the log in your report.
