Handling of "jumping" TreeGDE

[frankjaeger]

Vertical scrolling with "Mouse Wheel" doesn't work, if the width of TreeGDE is changed by:

onmouseover="...;this.style.width=350;"

You have to position the mousepointer to the scrollbar on the extended right edge. But if you go 1 Pix to much to the right the "onmouseout" let collapse the width. You have to go to the left to catch the scrollbar, but another "onmouseover" happens and you have to go to the right again.

It would be great to enable crolling by Mouse-Wheel.

Tested with Firefox 3.5.5 and IE 7 on XP.

changeset:4998 should fix these issues. Currently tested with FF 355 on linux an windows.

enlargetreewidth (new element var for treeGDE2)

• false (default): no enlargement of the div
• integer value: treeGDE div is enlarged (widened) on mouseover by the given value and restored to its initial width onmouseout. The treeGDE div binds the mousewheel event on mouseover, thus scrolling within the tree should be possible and no mousewheel zooming of the underlying mapframe should happen.

This makes the onmouseover onmouseout gui attributes of treeGDE obsolete.
