ARINC661 Maps interactivity

Several interactions are allowed on ARINC661 map widgets:

• Clicking on the background of a A661_MAPHORZ or A661_MAPVERT widget will trigger an event giving the world coordinates of the point which is under the cursor
• Using the Mouse wheel on a A661_MAPHORZ widget will trigger a specific event
• Selecting a MapItem will send selection event on the MapItem^[1]
  The selection of a MapItem means is implementation dependant. The standard does not specify if simply hovering over the mapItem will trigger the selection, or if a click is necessary

Clicking on the background of a Map widget

When clicking on the background of a A661_MAPHORZ or A661_MAPVERT widget, the A661_MAPHORZ_SOURCE widgets under the MapHorz will send an A661_EVT_SELECTION_MAP event with the world coordinate of the poiçnt under the cursor in the reference of the MapHorzSource.

Selecting a MapItem

When selecting a MapItem, the associated A661_MAPHORZ_ITEMLIST or A661_MAPVERT_ITEMLIST widget will send a A661_EVT_SELECTION event with the index of the selected MapItem.

The selection of a MapItem means is implementation dependant. The standard does not specify if simply hovering over the mapItem will trigger the selection, or if a click is necessary.
