WxHaskell and DragAndDrop
I would like to know how to use the following events handlers : dropTargetOnData, dropTargetOnDrop, dropTargetOnEnter, dropTargetOnDragOver….[1]
Could you check if my current believes are corrects :
From wx Widgets/ wxPython [2] / [3] / [4] it looks like they need to be used to manage DragAndDrog for non trivial examples. they are not actionable via an existing event like "on drag", etc.. I tried and create my own event. but it does not get "activated". [7] besides, from the signatures [1], these look like being activated on DropTarget, unlike other events on Reactive/ Windows/Controls . Is It Correct ?
Heinrich created its own events "onText", (in reactive-Banana) but this is on a Control. [6]
Could someone confirm these events effectively worked for them in WxHaskell, and maybe hint how to do that
I have tried you attached program and it gave the following tracing:
Drag.exe showMeDropDnD handler called: DragMove on Drag activated: on Enter:Point {pointX = 24, pointY = 6}
Build info: - Windows XP - GHC version 7.4.2 - wxWidgets-2.9.3 - wxHaskell from https://github.com/atzedijkstra/wxHaskell As no one else has responded so far, I think you are in uncharted territory; wxHaskell is huge and there are not many applications using it. If you have figured it all out, I hope you want to write a HaskellWiki page about it.
