mouseevent

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

Say i want to draw a rectangle on canvas. I want to be able to get the co-ordinates from user's mouse. Ideal scenario is user clicks at a point and drags down to another end like those rectangles we draw using paint. How can i draw a rectangle like we do in paint by dragging mouse? (how to get the co-ordinates of the mouse when he clicks mouse and leaves at?) Here's a outline of how to drag-draw a rectangle on canvas: In mousedown: save the starting mouse position set a flag indicating the drag has begun In mousemove: clear the canvas of the previous rectangle calculate the rectangle width

I'm looking for a way in Java to read in raw mouse input and not just the event listeners. I'll tell you what I'm doing. Essentially, there is a game where if you move the mouse to the right, I want Java to send key signals of the 'd' key being pushed down, and when the mouse is moved to the left, the 'a' key being held down. But, when you move the mouse, the game quickly corrects the mouse position and sends it right back into the middle of the screen. So, if you use mouse listener, you get one event of the mouse being moved to the right, then another quickly following of the mouse being move

I'm trying to develop a Mac OsX app provided by a system tray icon, so after the first attempt with the simplest code to achieve it I noticed that every apps tray icon's (both system and user apps) on mac osX (10.8) allows to activate the relative popup menu with both left and right click on it but with my project only the left (MouseEvent.BOTTON1) button causes the popup menu to pulldown. Here's my code: public class SystemTrayDemo { private SystemTray tray; private TrayIcon tray_icon; public SystemTrayDemo() { if (!SystemTray.isSupported()) { JOptionPane.showMessageDialog(null, "System tray

I have: private void button1_MouseEnter(object sender, EventArgs e) { for (int i = 0; i > 2; i++) { button1.Content = Convert.ToString(i); System.Threading.Thread.Sleep(1000); } tekst.Text = "Mouse Enter"; } When I enter on Button I see only Mouse Enter , but Content on Button don't change. Why? What I can do wrong? Your for loop never execute because you have wrong condition, change it to following code: for (int i = 0; i < 2; i++) Also you should use BackgroundWorker ( msdn ) to update your GUI dynamicly. private void button1_MouseEnter(object sender, MouseEventArgs e) { BackgroundWorker

I am using the following to get the mouse position: var coordinate = 0; ............ canvas1.addEventListener('mousemove', function (evt) { var mousePos = getMousePos(canvas1, evt); var nY = Math.round(mousePos.y); var nX = Math.round(mousePos.x); coordinate = "x=" + nX + ", y=" + nY; $('#pValue').val(coordinate); }, false); It works great if I display the value in a text field; however I could not update a text layer: dlayerA1Text = new Kinetic.Layer(); var simpleTextRight = new Kinetic.Text({ x: lOffset + (lOffset * 0.25), y: 15, text: coordinate, fontSize: 12, fontFamily: 'Calibri', fill:

I have a QWidget that contains QLabels and QLineEdits side by side. When I click on a QLabel, I can use the mousePressEvent in QWidget. But when I click on QLineEdit, I can't detect the mousePressEvent in QWidget - only in the QLineEdit. I think that it is related to how QLineEdit works - I don't know the way to get mouse events within the whole region. EDIT : I have made a custom channel box for Maya like above. I try to select multiple channels by dragging the mouse. But as I mentioned, in the QLineEdit regions I can't do this. class channelWidget(QtGui.QWidget): def __init__(self, parent
