Wiring a popup identify to a button? Button to initiate tool.

Question

I have a popup identify working well within the application.  What I am wanting to do is create a button that initiates the popup identify instead of simply left clicking on the feature and the popup comes up.  Here is my planned workflow:

1. Click on a popup button from the main toolbar (to initiate tool)
2. Click on the feature to identify attributes.
3. Click on the popup button again if I want to identify another feature.

I am wanting to do this so I am not always left clicking and a popup comes up.  Also, the click is competing with other tools within the application.

Has anyone been able to get this to work?  Any suggestions will be greatly appreciated.

Here it is. Here is the esri identify sample.      dojo.require("dijit.layout.BorderContainer");
      dojo.require("dijit.layout.ContentPane");
      dojo.require("esri.map");
      dojo.require("esri.layers.FeatureLayer");
      dojo.require("esri.dijit.Popup");
      dojo.require("dijit.form.Button");

var map;
      var evtOnMapClick;

function init() {
         ...
         dojo.connect(dijit.byId("identify"), "onClick", btnIdentify_onClick);
      }

function btnIdentify_onClick() {
    evtOnMapClick = map.on("click", onMapClick);
}

function onMapClick(e) {
    // identify the features and display the popup. Refer to esri identify sample
    
   // at the end
   if (evtOnMapClick) {
      evtOnMapClick.remove();
      evtOnMapClick = null;
   }
}

Define a variable which is a reference to the map.onClick event handler. Define the event handler when the button is clicked, and detach the event handler when the identify operation is complete. So the user has to click the popup button every time to start an identify operation.var evtOnMapClick; function btnPopup_onClick() { evtOnMapClick = map.on("click", onMapClick); } function onMapClick(e) { // identify the features and display the popup // at the end if (evtOnMapClick) { evtOnMapClick.remove(); evtOnMapClick = null; } } Hope it helps. Thanks. That looks promising. How would I incorporate this code block into this sample? San Francisco
