</div></div>Why did FRP not work for you? You could try reactive-banana[1], which has<br>
specific support for GUI. If you want something closer to MVP,<br>
binding-gtk[2][3] might help.<br>
<br>
If you post more details about your application, someone may be able to<br>
suggest a better way of structuring it. MVP originates from OO, and<br>
OO-centric patterns are usually not the best way to go about something in<br>
Haskell.<br>
