Wheelmouse Zoom function doing it twice

[belug]

In some examples the wheelmouse zoom is zooming twice.

Double zoom : http://geoprisma.org/samples/tms/index.php (without zoomSlider) http://geoprisma.org/samples/zoomslider/index.php (with zoomSlider)

Single zoom : http://geoprisma.org/samples/mapfishlayertree/index.php (without zoomSlider)

First I thought of a bug with zoomslider, but I've found a example without it.

For now I cannot find why.

Where

The issue comes from the MapPanel widget and only appears when the "pan" button is activated.

How

The issue is caused by 2 OpenLayers.Control.Navigation controls activated at the same time, one for the "pan" button, the other for the one created by the MapPanel widget itself and added to the Map.

Why

With the legacy Map widget, map navigation was not possible unless you clicked the "pan" button, which was pretty annoying. So, in the MapPanel widget, in order to solve this issue, a Navigation control was added by default. Now, since these two can be activated at the same time, it causes the "double zoom" issue when using the mouse scroll.

Solution

This could be quickly fixed by removing the "pan" button scroll zooming by setting its Navigation control "zoomWheelEnabled" property to false.

What do you think ?

[belug]

Tested it with the fix proposed and it resolve the bug. But this fix make it not optionnal. This could be set as an optionnal parameter of the toolbar and by default false (To turn of the zoomWheelEnabled.

Turn off the zoomWheel on the pan action of the toolbar

The fix disables zoom using the wheel when using the Map widget, but since it's deprecated it's okay to do so.

Fixed in r1247.
