javascript - OpenLayers DrawFeature control with Point destroys double click to zoom -


i have simple code copied 1 of openlayers examples drawing several different types of geometries on map. problem is, whenever "point" geometry selected, lose ability double-click zoom in. difference between examples , code i'm registering handlers use mod_shift, because want retain ability pan/zoom. here snipit of code:

   point: new openlayers.control.drawfeature(this.geometryfilterlayer,                             openlayers.handler.point,                               {                                 'done':  console.info("drew point")                             },                              {                                 keymask: openlayers.handler.mod_shift                             }                             ),                         polygon: new openlayers.control.drawfeature(this.geometryfilterlayer,                             openlayers.handler.polygon,                              {                                 'done':  console.info("drew polygon")                             },                              {                                 keymask: openlayers.handler.mod_shift                             }                             ),

the funny thing above code is, 'done' event gets fired when control/handler created, , keymask doesn't work @ -- have loop through object , manually set keymask each time, that's not real problem @ hand.

i've tried every way can think of register dblclick event, no matter what, can't zoom in when double click. works fine on other geometries (bbox, point/radius, , polygon).

can give me advice?

i never solved issue, ended doing away using mod_xxx altogether. each different draw control had built-in functionality happens when hold shift, ctrl, alt, etc. ended using custom buttons , toolbar, way user can explicitly select drawing control themselves.

this.toolbar = new openlayers.control.panel({                 displayclass: 'olcontroleditingtoolbar'             });             map.addcontrol(this.toolbar);  var navbutton = new openlayers.control.button({                 displayclass: "olcontrolnavigation",                  title: "navigation",                 trigger: lang.hitch(this, function(data){                     this.toggledrawcontrol("navigation");                      navbutton.activate();                     pointbutton.deactivate();                     bboxbutton.deactivate();                     pointradiusbutton.deactivate();                     polygonbutton.deactivate();                 })             });   ...  this.toolbar.addcontrols([navbutton, pointbutton, bboxbutton, pointradiusbutton, polygonbutton]);

and function toggle draw controls (can called externally, that's why re-call activate , deactivate functions:

 toggledrawcontrol: function(geometrytype){             this.currentgeometrytype = geometrytype;             for(key in this.drawcontrols) {                 var control = this.drawcontrols[key];                 if(geometrytype == key) {                     control.activate();                     this.drawingbuttons[key].activate();                 } else {                     control.deactivate();                     this.drawingbuttons[key].deactivate();                 }             }         }
