You can try this out in the local tutorial editor (you'll need to fix the url's host and port). |
Add an event that allows changing the selection order for feature.mouseover. Also, add two common handlers for such ordering. Specifically, the geo.event.feature.mouseover_order event is triggered if the mouse is located on multiple elements of a feature. The `feature.mouseOverOrderHighestIndex` function will always sort these so that the highest index element is on top. The `polygonFeature.mouseOverOrderClosestBorder` function will sort polygons so that they are sorted based on how far the mouse is from their borders, with the closest on top. Note that, as always, the mouse must be within the polygon for it to be considered.
One event is generate per feature that is under the mouse when a mouse click is generated on features. By reordering them, this affects the order those events are generated and tags a different event as the top element. This also fixes some documentation.

Here is another tutorial that will show the mouse click ordering. |
