mousemove

I currently have a div structured with other elements inside of it. Something similar to below; <div id="container" style="position: relative; width: 500px; height: 500px;"> <div style="position: absolute; left: 50px; top: 50px;"></div> <div style="position: absolute; left: 100px; top: 100px;"></div> </div> I am trying to get the mouse position relative to the div with the id container . So far I have this; function onMousemove(event) { x = event.offsetX; y = event.offsetY; }; var elem = document.getElementById("container"); elem.addEventListener("mousemove", onMousemove, false); This works

I'm trying to figure out a clean way to aggregate mousemove events so that I ensure my code gets called, but only once every 250-300 milliseconds. I've thought about using something like the following, but was wondering if there was a better pattern, or something jQuery provides that will do the same thing: var mousemove_timeout = null; $('body').mousemove(function() { if (mousemove_timeout == null) { mousemove_timeout = window.setTimeout(myFunction, 250); } }); function myFunction() { /* * Run my code... */ mousemove_timeout = null; } EDIT: The accepted answer below would work perfectly for

I'm trying to make a "line" of image thumbs, where it scrolls on mousemove. And I got it to work, but my problem now is that i wanted to make a "padding" on the sides so I doesn't have to have the mouse all the way out to the sides to see the first/last thumb. But I really really can't get it to work :/ This is the script I have now: // MouseMove scrolling on thumbs var box = $('.thumbs-block'), innerBox = $('.thumbs'), lastElement = innerBox.find('a:last-child'); var offsetPx = 100; var boxOffset = box.offset().left; var boxWidth = box.width() /* - (offsetPx*2)*/; var innerBoxWidth =

When running the demo App below, the problem I run into is that hover messages for the bottom part of the plot end up running off the screen. Does anybody know if there is a way to adjust the position so that the entire message always falls within the screen boundaries (l,r,t,b)? require('shiny') require('ggplot2') library(DT) ui <- pageWithSidebar( headerPanel("Hover off the page"), sidebarPanel(width = 2 ), mainPanel( tags$head( tags$style(' #my_tooltip { position: absolute; pointer-events:none; z-index: 1; padding: 0; }'), tags$script(' $(document).ready(function() { setTimeout(function(){

In Windows when I create a QMainWindow I can move it around the screen by clicking the title bar and dragging it. In my application I've hidden the title bar by using setWindowFlags(Qt::CustomizeWindowHint) and I'm trying to build a custom title bar using a widget and setting it in the menu space with setMenuWidget(myWidget) . Now I want to reproduce the original behaviour: I want to click on my MyWidget widget inside the QMainWindow and, while mouse is pressed, dragging the mouse moves the window. Is there a way to do it? This is an example on how to implement a fake title bar, that has

Hi! I am trying to write a program where I need to report the position of every mouse motion. I have called the XSelectInput() function with a PointerMotionMask mask. Everything seems to work alright but the numbers after printing don't appear after every movement, they appear in blocks and also the numbers in event.xmotion.x and event.xmotion.y are very high, in the hundred thousands. What is causing these large numbers? Also is my program getting every number and reporting it immediately or is it being stored in a queue and sent in blocks to the terminal? Thanks Here's my event loop: while(1
