View Full Version : xy co-ordinates on image for mouse events

19 Apr 2013, 6:44 AM
I want to capture xy co-ordinates on my map image for the mouse events. I checked event object passed from the mouse event but it doesn't seem to be giving correct co-ordinates across all the browsers. How can I make sure that which property I need to use for particular browser? The co-ordinates should be relevant to the container of the image rather than the screen. Any suggestions?

With the click listener you'll have access to the Ext eventobject. Try using:

function (e) {

e.getXY doesn't give co-ordinates w.r.t. container of the image. It seems e.getXY is the values of screen co-ordinates. I tried e.browserEvent.offsetX and offsetY, that gives same value of window.event.offsetX and offsetY. But that works for Chrome only.

You can get the region with Ext.util.Region.getRegion(cmp) for a specific component (e.g Ext.util.Region.getRegion(Ext.getBody())). If you use your image for the component and event.getXY() you should be able to to calculate the position of the event relative to the image coordinates. This works for me in another use case for IE, Firefox, and Safari.

Oh, I see.
See if this is better:

Ext.widget('image', {
renderTo: Ext.getBody()
, height: 24
, width: 24
, src: 'http://cdn.sencha.io/img/home/december-2012/icon-blog.png'
, listeners: {
afterrender: function () {
var me = this;
me.el.on('click', function (e) {
console.log(e.getX() - me.el.getX());
