Problem with toolbar.deactivate(); method for draw toolbar

GISProgrammer — Fri, 07 Jun 2013 21:24:18 GMT

I took a look at the drawing tools example and got it up and running fairly quickly (I seperated out the html code and the js code into two seperate files).

I see the toolbar.deactivate(); method works in the example but I can't get it to work in my code. I'm adding it everywhere and I even created a button to deactivate it.

dojo.connect(dojo.byId("drawPolygon"),"click", function(){
         tb.deactivate();

http://developers.arcgis.com/en/javascript/jsapi/draw.html

It just doesn't work!

Here's my code

[HTML]


       <div id="info">
      <div>Select a shape then draw on map to add graphic</div>

          <button id="deactivateDraw" data-dojo-type="dijit.form.Button" data-dojo-props='onClick:function(){ initToolbar();}'>DeActivate</button>
    <button id="drawExtent" data-dojo-type="dijit.form.Button" data-dojo-props='onClick:function(){ initToolbar();}'>Extent</button>


         


       </div>

[/HTML]

 var tb; //toolbar for draw tools      //*************** TOOLBAR CODE ******************************   function initToolbar() {         tb = new esri.toolbars.Draw(map);         dojo.connect(tb, "onDrawEnd", addGraphic);             dojo.connect(dojo.byId("drawExtent"),"click", function(){           tb.activate(esri.toolbars.Draw.EXTENT);     map.hideZoomSlider();         });            dojo.connect(dojo.byId("deactivateDraw"),"click", function(){          tb.deactivate();          map.showZoomSlider();           });       }         //*************** END TOOLBAR CODE ******************************     function addGraphic(geometry) {         // try to deactivate the toolbar and clear existing graphics    var symbol;         tb.deactivate(); //doesn't work   map.showZoomSlider(); //works         map.graphics.clear(); //works          switch (geometry.type) {           case "point":           case "multipoint":             symbol = new esri.symbol.SimpleMarkerSymbol();             break;           case "polyline":             symbol = new esri.symbol.SimpleLineSymbol();             break;           default:             symbol = new esri.symbol.SimpleFillSymbol();             break;         }         var graphic = new esri.Graphic(geometry, symbol);         map.graphics.add(graphic);     tb.deactivate();            }  //*************** END TOOLBAR CODE ******************************

after a quick scan through your code, I noticed that even on the onClick for the Deactivate button you are calling initToolBar() funtion which will again activate the toolbar.

 <button id="deactivateDraw" data-dojo-type="dijit.form.Button"  data-dojo-props='onClick:function(){ initToolbar();}'>DeActivate</button>

Write another function to deactivate the toolbar.

//*************** TOOLBAR CODE ******************************

 function initToolbar() {
        tb = new esri.toolbars.Draw(map);
        dojo.connect(tb, "onDrawEnd", addGraphic);
  

        dojo.connect(dojo.byId("drawExtent"),"click", function(){
          tb.activate(esri.toolbars.Draw.EXTENT);
    map.hideZoomSlider();
        });
}

function deactivateToolbar(){
 tb.deactivate(); 
        map.showZoomSlider(); 
}

and in the HTML call that function on clicking the deactivate button:

 <button id="deactivateDraw" data-dojo-type="dijit.form.Button"  data-dojo-props='onClick:deactivateToolbar();'>DeActivate</button>

Let me know if it helps.

Shreyas,

Thanks for the reply.

I added your code and no luck...still doesn't work. I know it is respecting the new function to deactivate because when I hit the deactivate button it shows the map zoom slider. I also added a alert message just to make sure it hitting the method/button click and it is:

 function deactivateDrawToolbar(){
        tb.deactivate(); 
  window.alert('Yuup')
        map.showZoomSlider(); 
  }

In my previous post you can see I have the tb.deactivate(); code in my addGraphic function. I would like to just have it hear so and turn off the draw tools have the graphics are added so the endusers don't have to hit another button. I only try to add a deactivate button to try and isolate the problem.

Any more ideas?

Thanks

Re: Problem with toolbar.deactivate(); method for draw toolbar

BenFousek — Mon, 10 Jun 2013 19:24:47 GMT

A couple other things with your code that may or may not be causing problems.

1) You should be using dijit.byId() instead of dojo.byId(). dojo.byId() is for regular elements like '<div id="myDiv"></div>', while dijit.byId() should be used for dijits like '<div id="myDiv" data-dojo-type="dijit/form/Button"></div>'.

2) When you connect to a dijit the onClick event is 'onClick', not 'click'.

3) You don't need to recreate the toolbar every time. In your initialization code, after you have created the map, create the toolbar once using a global var like you have done. I create one toolbar and use it for everything that may need to draw, e.g. measurement, creating features, etc.

3) The onClick property in data-dojo-props does not need to be wrapped in a function or use parentheses if you are not passing variables.
[HTML]<div id="myDiv" data-dojo-type="dijit/form/Button" data-dojo-props="onClick: myFunction "></div>[/HTML]

4) You should disconnect from events once they fire. The way your code is now every time the toolbar is initialized you add another identical 'onDrawEnd' listener. It's not that big of a deal if the user just performs 1 or 2 cycles through the task, but it adds up to decreased performance in a heavily used app.

Here's how I would do it with one function:

var map, tb; function init() {  //initialize the app    map = new esri.Map({});    tb = new esri.toolbars.Draw(map); }  function draw() {  tb.activate(esri.toolbars.Draw.EXTENT);  var conn = new dojo.connect(tb, 'onDrawEnd', function(evt) {   dojo.disconnect(conn); //disconnect      tb.deactivate();      map.graphics.clear();      //create and add graphic  }); }

Shreyas,

The sample works. Looks the similar to the sample on ESRI resources JS page and that works too. Something must be wrong with my code and I'm not sure??? I have some query tasks/buttons and if I migrate to API 3.3, 3.4, or 3.5 they break. Currently they work at 3.2...just changing the api ref makes the buttons not work. Not entirely sure what is happening. I'm trying to separate all my code into different JS file (one for each tool/function) so I can reuse more easily in other apps. Not sure??

Ben,

Thanks for all the suggestions that cleared a bunch stuff up for me. I'm self taught and I appreciate it.

As I mentioned before I have a .js script firing in 3.2 API but it doesn't work in the 3.5 API and I'm not sure. It seems like it fails at my switch statement.

Any ideas

I have all but given up on switch. Kept running into unexplained problems. This is out of an identify task, but same concept.

var feature = results[0].feature;
var atts = feature.attributes;
var type = feature.geometry.type;
if (type == 'point') {
 var sym = POINT_SYMBOL
} else if (type == 'polyline') {
 var sym = POlYLINE_SYMBOL
} else if (type == 'polygon') {
 var sym = POLYGON_SYMBOL
}
var graphic = new esri.Graphic(feature.geometry, sym, atts, null);

Also, I always create an esri.Graphic.

Re: Problem with toolbar.deactivate(); method for draw toolbar

GISProgrammer — Wed, 12 Jun 2013 21:18:11 GMT

Ben,

Thanks for the heads up but that didn't help. I'm using the same basic switch state for my find and addrss search task and they work. I reworte using the if / if else statements and same result. The grid opens but never populates and the features never get selected so the map doesn't zoom. For some reasone all my query tasks break if I move out of 3.2...hence the reason why I never update. I'm been dealing with this issue since 3.3 and I've spent days on it. I guess I might start another post and post all my code on that new thread to see if ESRI can help.

Thanks

Check out the list of breaking changes between version 3.2 and 3.3 here.

If they don't help resolve your upgrade issue can you post a simplified version of your problem code?
