Implemented as part of drag+drop support.
Thanks for the patch, Charles -- that gave me an excellent headstart on this task. I did end up making a number of changes, some related to bugs but probably more related to various re-factorings to share logic between this and other related tasks.
I think it could be worthwhile to review and compare the fixes you have made in your own code with what selenium has now. Would you mind attaching your latest to this JIRA issue so I could compare what you have with selenium's code? Sure, no problem. Except I can't figure out how to attach another file...so its inline below.
Any thoughts on when the next release will be? I'd be happy to download the latest and greatest to test these changes when they are ready. Thanks, Charlie ----------------- /* Taken from prototype library */ function getElementOffset(element) { var valueT = 0, valueL = 0; do { valueT += element.offsetTop || 0; valueL += element.offsetLeft || 0; element = element.offsetParent; } while (element); return [valueL, valueT]; } function getClientXY(element, coordString) { // Parse coordString var x = 0 var y = 0 if (coordString && coordString.trim() != '') { var coords = coordString.split(/,/) x = Number(coords[0]) y = Number(coords[1]) } // Get position of element var offset = getElementOffset(element) // Return 2 item array with clientX and clientY return [offset[0] + x, offset[1] + y] } function triggerMouseEvent(element, eventType, canBubble, clientX, clientY) { canBubble = (typeof(canBubble) == undefined) ? true : canBubble; clientX = clientX || 0 clientY = clientY || 0 var screenX = 0 var screenY = 0 if (window.screenX) { // Firefox screenX = window.screenX + clientX screenY = window.screenY + clientY } else if (window.screenLeft) { // IE screenX = window.screenLeft + clientX screenY = window.screenTop + clientY } if (element.fireEvent) { var mouseEvent = document.createEventObject() mouseEvent.clientX = clientX mouseEvent.clientY = clientY mouseEvent.screenX = screenX mouseEvent.screenY = screenY element.fireEvent('on' + eventType); } else { var evt = document.createEvent('MouseEvents'); if (evt.initMouseEvent) { evt.initMouseEvent(eventType, canBubble, true, document.defaultView, 1, screenX, screenY, clientX, clientY, false, false, false, false, 0, null) } else { // Safari // TODO we should be initialising other mouse-event related attributes here evt.initEvent(eventType, canBubble, true); } element.dispatchEvent(evt); } } Selenium.prototype.doClick = function(locator, coordString) { /** * Clicks on a link, button, checkbox or radio button.

My guess is that it will be within the next week or so.

New Feature
Closed
Minor
selenium server should accept commands to control the position of the mouse pointer
What the code does:
* Adds mouseOut, mouseUp, mouseMove events
* For each mouse event, and click, you can specify a parameter which is the x,y coordinates of the click. So something like this:
mouseMove | some_id | 17, 12
* Mouse coordinates are assumed to be in relation to the element of interest. So if "some_id" is a div tag at 10,10, then the mouse move event will be generated with coordinates of 27, 22. Its easy to change this to document coordinates, but this seemed easier.
* Update the browser bots to support mouse locations
* Updated the triggerMouseEvent to work with IE also. Note one big caveat to IE - user generated events do not bubble.
Hope this helps - feel free to ask questions. And if you'd prefer a patch let me know.
