[wxhaskell-users] Bug on mouse events

[<72...@in...>]

First of all, please pardon my clumsy english. I am Jose David Fernandez, a 
computer studies student at the university of Malaga, Spain. I am developing a 
yahu-liked GUI on top of WXH, like your WX, as a project for finish my studies. 
I know this is not the moment for comment anything, since certainly everybody 
are on holydays, but I want to report a bug before I forget to do it.

Your mouse event handlers receive a MouseEvent data as argument. This data can 
have the constructors MouseLeftDrag, MouseRightDrag, MouseMiddleDrag, and 
others. You get the button that is dragging by consulting the 
mouseEventGetButton method. But (and here is the bug) this method returns -1 on 
a wxEVT_MOTION event (see wxwindows docs), and the mouseEventDragging method 
only returns TRUE on wxEVT_MOTION, so your data event converter always yields 
MouseLeftDrag (the default choice), never the other two MouseXXXDrag.

I have been looking for a solution. I think you should use the methods 
XXXIsDown, what is I am going to do in my library. I hope I have been useful.

I would want to comment another thing. Since I am working with the WXH package, 
I need the sources for consulting. You have packed all them except wxcClasses 
and wxcDefs. I am working now with older ones, and I think I can get newer ones 
from the CVS, but it would be useful that you put them in the source release in 
your download page.

Thank you for this wonderful port of wxwindows to haskell and happy return from 
holyday.
