OpenLayers.Control.MouseDefaults

Control to set up mouse handling. This includes clicks, double clicks, scrollwheel events, and mouse movement. There are a number of functions which act as the default handlers for these events: if you wish to create your own mouse control which behaves differently, you should create a subclass of MouseDefaults, replacing the functions whose behavior you wish to change.

* Constructor

  OpenLayers.Control() -- Creates a new control. No options available.

* Methods

  defaultClick -- none -- This event takes place when a click event occurs on the map.

  defaultDblClick -- none -- This event re-centers the map on the clicked location.

  defaultMouseDown -- none -- This event starts a dragging event, so that the map can be dragged. If the shift key is held, it starts a 'zoombox' or rubber-band-zoom action instead.

  defaultMouseMove -- none -- If a mouseDrag is in operation, this function causes the map to move to follow the cursor. If a zoombox is in place, this increases the size of the zoombox element to match the cursor.

  defaultMouseUp -- none -- This function is called when a mouseup event is received, and either sets the center of the map to be the final location or zooms to the zoombox if enabled.

  defaultMouseOut -- none -- This calls defaultMouseUp, so that when you mouse out of the map div, the events are stopped.

  defaultWheelUp -- none -- Zooms in one level. Called by onWheelEvent

  defaultWheelDown -- none -- Zooms out one level. Called by onWheelEvent.

  onWheelEvent -- none -- catches the map wheel event, and handles it, zooming appropriately.
