mouse

问题 What I want to do is to manipulate the mouse. It will be a simple macro for my own purposes. So it will move my mouse to certain position on the screen and click like I am clicking with certain interval. 回答1: Here's a code that is using unmanaged functions to simulate mouse clicks : //This is a replacement for Cursor.Position in WinForms [System.Runtime.InteropServices.DllImport("user32.dll")] static extern bool SetCursorPos(int x, int y); [System.Runtime.InteropServices.DllImport("user32.dll

问题 This question already has answers here : How do I get the coordinates of a mouse click on a canvas element? (22 answers) Closed 7 months ago . First, I know this question has been asked many times. However, the answers provided are not consistent and a variety of methods are used to get the mouse position. A few examples: Method 1: canvas.onmousemove = function (event) { // this object refers to canvas object Mouse = { x: event.pageX - this.offsetLeft, y: event.pageY - this.offsetTop } }

问题 I'm trying to prevent a mousewheel event captured by an element of the page to cause scrolling. I expected false as last parameter to have the expected result, but using the mouse wheel over this "canvas" element still causes scrolling: this.canvas.addEventListener('mousewheel', function(event) { mouseController.wheel(event); }, false); Outside of this "canvas" element, the scroll needs to happen. Inside, it must only trigger the .wheel() method. What am I doing wrong? 回答1: You can do so by

问题 I have a link that, when clicked, I would like it to move the position of the mouse to the right (or anywhere within the viewport, for that matter). in code it would probably look similar to the following: $('a#expand').click(function(e){ $(document) .mouseXPos(e.pageX + 50) .mouseYPos(e.pageY + 50); }); Chaining might not be necessary, of course, but a similar 'set mouse position' functionality is what I am after. I've seen solutions to move the cursor position to a certain spot in the text,

问题 I have a little problem with mapping vim shortcuts for my mouse wheel. I can't make this work : set mouse=a set nowrap noremap <C-ScrollWheelUp> 3zh noremap <C-ScrollWheelDown> 3zl On the other hand, the following is working (but not convenient, i just tested it to see if ScrollWheelUp/Down was working) : set mouse=a set nowrap noremap <ScrollWheelUp> 3zh noremap <ScrollWheelDown> 3zl What is my problem ? 来源： https://stackoverflow.com/questions/17083641/cant-make-work-scrollwheel-map-in-vim

问题 I have a school project about it security. My job is it to customize a hardware mouse with a usb hub and a teensy to program it. The code on the teensy gets executed when it gets dark (light dependent resistor). The code takes some files on the win7 vm and upload them to an Apache2 server hosted on a kali vm (via cmd commands in win7 vm). Everything works fine in vmware, but I have to use virtualbox for my project. My problem is now that in virtualbox the cmd commands randomly changes with

问题 on TableHeader, I try to make a right click with the mouse as follow : tableHeader.click(MouseEvent.BUTTON3); but this is not working, have you any idea/suggestion ? thanks, 回答1: if it is because you want to show a popupmenu then you can do it like this:: popupMenu.show(tableHeader, 0, 0); if it is because you want to get into a mouselistener like: class MyMouseListener implements MouseListener{ @Override public void mouseReleased(MouseEvent arg0) { if(SwingUtilities.isRightMouseButton(arg0))

问题 I want to draw a set of disconnected lines on top of an image by dragging the mouse while pressing the left button. However, if I click on a previously drawn line to specify the starting point of the next line, the callback function is not being called and I don't get the point. Here is my code: function main_test S.fH = figure('menubar','none'); im = imread( 'image.jpg' ); S.aH = axes; S.iH = imshow( im ); hold on axis image; X = []; Y = []; set(S.aH,'ButtonDownFcn',@startDragFcn) set(S.iH,

问题 I am trying to solve a question which has been bugging me for a while, can someone explain to me how to make the *red rectangle face/aim towards my mouse and explain to me how it works it would be awesome!!! Here is the Fiddle var canvas = document.getElementById('canvas'); var context = canvas.getContext('2d'); var player = { x: 200, y: 200, } drawPlayer = function(something) { context.beginPath(); context.fillStyle = "blue"; context.arc(something.x, something.y, 30, 0, 2 * Math.PI); context

问题 Problem I have a GameObject in my scene and I want that GameObject to rotate so it faces my mouse when I click it. After the rotation it's supposed to move in the direction it is now facing. However it almost works. Example For instance lets say the hypotenuse is: 4.592912 and the adjacent is: 3.042814, then i take MathF.Cos(adjacent/hypotenuse) = 0.6625021, now i take MathF.Acos(0.6625021) * MathF.Rad2Deg = 37.95857 GIF from the scene: Code float mouseX, mouseY; float playerX, playerY; float
