While trying out the dynapi I was having some issues with Internet =
Explorer 5 and mouse event handling so I dug through the code and made =
some alterations to events.jsp. I figured that I would pass them on to =
this mailing list in case the changes I made could be useful to any one =
else. Since I do not subscribe to this list myself, if anyone wants to =
discuss my changes, please feel free to email me at kh...@qu...
The changes are as follows:
in the DynLayer.prototype.EventMethod I added the following code to =
determine which dynAPI layer was associated with the mouse event. The =
reason for this code is that a layer which contains other elements that =
can respond to the mouse events will receive a mouse event through the =
IE event bubbling paradigm where the events srcElement will not be equal =
to the layer itself but to its subcomponent such as a <TD> element or a =
<FONT> element, therefore, in order to find the appropriate dynLayer =
object to associated the mouse event with, you must search through the =
srcElements object hierarchy to find a dynLayer. That is what the =
following code does. I put this code right under the current is.ie block =
in the DynLayer.prototype.EventMethod
