11 | -/** | |
12 | - * Class: OpenLayers.Control | |
13 | - * Controls affect the display or behavior of the map. They allow everything | |
14 | - * from panning and zooming to displaying a scale indicator. Controls by | |
15 | - * default are added to the map they are contained within however it is | |
16 | - * possible to add a control to an external div by passing the div in the | |
17 | - * options parameter. | |
18 | - * | |
19 | - * Example: | |
20 | - * The following example shows how to add many of the common controls | |
21 | - * to a map. | |
22 | - * | |
23 | - * > var map = new OpenLayers.Map('map', { controls: [] }); | |
24 | - * > | |
25 | - * > map.addControl(new OpenLayers.Control.PanZoomBar()); | |
26 | - * > map.addControl(new OpenLayers.Control.MouseToolbar()); | |
27 | - * > map.addControl(new OpenLayers.Control.LayerSwitcher({'ascending':false})); | |
28 | - * > map.addControl(new OpenLayers.Control.Permalink()); | |
29 | - * > map.addControl(new OpenLayers.Control.Permalink('permalink')); | |
30 | - * > map.addControl(new OpenLayers.Control.MousePosition()); | |
31 | - * > map.addControl(new OpenLayers.Control.OverviewMap()); | |
32 | - * > map.addControl(new OpenLayers.Control.KeyboardDefaults()); | |
33 | - * | |
34 | - * The next code fragment is a quick example of how to intercept | |
35 | - * shift-mouse click to display the extent of the bounding box | |
36 | - * dragged out by the user. Usually controls are not created | |
37 | - * in exactly this manner. See the source for a more complete | |
38 | - * example: | |
39 | - * | |
40 | - * > var control = new OpenLayers.Control(); | |
41 | - * > OpenLayers.Util.extend(control, { | |
42 | - * > draw: function () { | |
43 | - * > // this Handler.Box will intercept the shift-mousedown | |
44 | - * > // before Control.MouseDefault gets to see it | |
45 | - * > this.box = new OpenLayers.Handler.Box( control, | |
46 | - * > {"done": this.notice}, | |
47 | - * > {keyMask: OpenLayers.Handler.MOD_SHIFT}); | |
48 | - * > this.box.activate(); | |
49 | - * > }, | |

52 | - * > OpenLayers.Console.userError(bounds); | |
