You can’t do that by sending messages, instead use SendInput Windows API. Call method ClickOnPoint, this is an example from form click event, so this.handle is form handle, note that these are client coordinates on window witch handle is send, you can easily change this and send screen coordinates, and in that case you don’t … Read more
There are several things that should be changed: The drawing and button code shouldn’t be in the event loop but in the outer while loop. You’re calling the button function every time an event occurs (for example if the mouse moves). The button function is doing too much. It creates and blits text surfaces, draws … Read more
Regarding Pax’ solution: it doesn’t work if user clicks more than one button intentionally or accidentally. Don’t ask me how I know :-(. The correct code should be like that: var mouseDown = 0; document.body.onmousedown = function() { ++mouseDown; } document.body.onmouseup = function() { –mouseDown; } With the test like this: if(mouseDown){ // crikey! isn’t … Read more
It is possible though limited: Add an AWTEventListener for focus events. As long as your app has focus before the button is clicked you’ll receive a focus lost event. Then query for the pointer position. The limitation is that, of course, your app loses focus. So depending on what you are ultimately trying to achieve … Read more
I do automated testing stuff in Python. I tend to use the following: http://www.tizmoi.net/watsup/intro.html Edit: Link is dead, archived version: https://web.archive.org/web/20100224025508/http://www.tizmoi.net/watsup/intro.html http://www.mayukhbose.com/python/IEC/index.php I do not always (almost never) simulate key presses and mouse movement. I usually use COM to set values of windows objects and call their .click() methods. You can send keypress signals with … Read more
MouseInfo.getPointerInfo().getLocation() might be helpful. It returns a Point object corresponding to current mouse position.
DEMO There’s a really cool function called document.elementFromPoint which does what it sounds like. What we need is to find the x and y coords of the mouse and then call it using those values: document.addEventListener(‘mousemove’, e => { console.clear() console.log( document.elementFromPoint(e.clientX, e.clientY) ) }, {passive: true}) [class^=’level’]{ width: 100px; height: 100px; padding: 15px; background: … Read more
Please keep in mind that my answer has aged a lot. This type of behavior is usually desired while implementing drag-drop behavior on an html page. The solution below was tested on IE 8.0.6, FireFox 3.6.6, Opera 10.53, and Safari 4 on an MS Windows XP machine. First a little function from Peter-Paul Koch; cross … Read more
More than a few hundred components is awkward. One easy way to get big pixels is to use drawImage() and scale the mouse coordinates as shown here and here. Here’s a simple example. import java.awt.Dimension; import java.awt.EventQueue; import java.awt.Graphics; import java.awt.Graphics2D; import java.awt.Point; import java.awt.event.MouseEvent; import java.awt.event.MouseMotionListener; import java.awt.image.BufferedImage; import javax.swing.Icon; import javax.swing.JFrame; import javax.swing.JPanel; … Read more
You cannot move the mousepointer with javascript. Just think about the implications for a second, if you could 😉 User thinks: “hey I’d like to click this link” Javascript moves mousecursor to another link User clicks wrong link and inadvertently downloads malware that formats his c-drive and eats his candy
