Zoom in - click instead of drawing box?

[SusanMordy1]

Users are used to clicking on the screen to zoom out with the zoom out tool, instead of drawing a box.

In ArcMap, the zoom out tool allows users to click on the screen to zoom out in addition to drawing a box to zoom out.

It is possible to do this with the FSV?

It would require a code change. I've updated the NavigationTools.mxml sample to show how it can be done. See the myMap_mapClickHandler function.

Thanks Dasa. I added some of the above code to mapManager.mxml but I get the following error:

Defintion import com.esri.ags.tools.NavigationTool; could not be found

You'll need to use the 1.x name:
