mouseevent

I am writing a code for eye tracker using OS X / X Code / OpenCV 2.2. As part of the Eye Tracker training process, I am using cvSetMouseCallback to capture the data as per following: Right click for right eye; Left click for left eye. However, I found that the program could only work with left click (CV_EVENT_LBUTTONDOWN) while it does not work with right click (CV_EVENT_RBUTTONDOWN). At first, I thought it was a trackpad and mouse setting issues, however, it turns out that I have already set both Secondary Click as "Right" in the machine. Appreciate if someone could shed some light on this?

I am tracking mouse movements using the following JavaScript: var mouseX = 0; var mouseY = 0; document.onmousemove = function (e) { mouseX = e.clientX; mouseY = e.clientY; } My problem is that if the mouse hasn't been moved since the page had been loaded, the mouseX and mouseY values both equal 0. How can I get the mouse values when the page is loaded as well as when the mouse is moved? The browser doesn't know where the mouse is until it moves. It's more complicated than just "get me the cursor position". What if there is no mouse (tablet) or what if the mouse is not over the browser window?

Handling the

Here's a JSFiddle of the behavior I'm seeing, relating to middle-click and the click event in Chrome and FF. 'click' kinda sorta works Approach 1 : Bind a click handler directly to an a element and a middle-click will trigger the handler in Chrome but not in FF. $('div a').on('click', function(ev) { // middle click triggers this handler }); Approach 2 : Bind a delegated click handler to a div which contains one or more a . Middle click will not trigger this handler in Chrome or FF. $('div').on('click', 'a', function(ev) { // middle click doesn't trigger this handler }); This approach is
