mouseevent

问题 I am using sockets in c# in order to send data from server to client machine. In fact I have created a capturer which capature kinect stream from 3 different machine. I want to generate a server and client communication in order to send signal from server to the rest devices in order to begin and stop the recording process. I want with left click to send a message to begin recording and with right click to stop recording. My code is the following: public Form1() { InitializeComponent(); this

问题 I have been attempting to add an on "click" event to an SVG element in Elm in order to determine the relative position of the mouse click within that element. A code sample is given below that you can try running at http://elm-lang.org/try to show how click events on HTML elements seem to work as expected but not on SVG elements. In the sample, Html.on "click" is used rather than Html.onClick to allow the position data to be decoded from the event as explained in this discussion. After

问题 So I'm trying write a program that detects a mouse click on an image and saves the x,y position. I've been using matplotlib and I have it working with a basic plot, but when I try to use the same code with an image, I get the following error: cid = implot.canvas.mpl_connect('button_press_event', onclick) 'AxesImage' object has no attribute 'canvas' This is my code: import matplotlib.pyplot as plt im = plt.imread('image.PNG') implot = plt.imshow(im) def onclick(event): if event.xdata != None

问题 I am trying to make an application where the mouse goes to certain locations on screen and automatically clicks left button. The problem is I cant click outside the Qt application so I made a workaround by making the application transparent to mouse clicks and making it full screen using this code: int x = 800; int y = 500; this->setWindowFlags(Qt::WindowStaysOnTopHint|Qt::FramelessWindowHint|Qt::ToolTip); this->setAttribute(Qt::WA_TranslucentBackground); this->setAttribute( Qt::WA

问题 I have a table where i want to change cell background on mouse over and mouse button down, my current solution doesn't work as I want it to : function ChangeColor(sender) { sender.style.backgroundColor = 'yellow'; } var clicking = false; $(document).mouseup(function() { clicking = false; }); $(document).ready(function() { $('#Table1 tr').each(function() { $('td', this).each(function() { $(this).mousedown(function() { clicking = true; }); $(this).mousedown(function(event) { if (clicking==true)

问题 I created this class, and it works perfectly for make my WPF application transparent to mouse events. using System.Runtime.InteropServices; class Win32 { public const int WS_EX_TRANSPARENT = 0x00000020; public const int GWL_EXSTYLE = (-20); [DllImport("user32.dll")] public static extern int GetWindowLong(IntPtr hwnd, int index); [DllImport("user32.dll")] public static extern int SetWindowLong(IntPtr hwnd, int index, int newStyle); public static void makeTransparent(IntPtr hwnd) { // Change

问题 I've tried to implement a page panorate by dragging. In my implementation the page moves for a while after user has released the mouse button, like dragging maps in Google Maps. Now I'd like to prevent this effect, when the mouse is no longer moving when user releases the button. The problem is, that I just can't figure out how to detect if the mouse really moves when mouseup event is fired. For now I've tried to tackle this problem by calculating the dragging speed and then compare the speed

问题 In Mathematica, locators can be constrained to certain screen regions via the parameters of LocatorPane (See LocatorPane documentation.) A list of three ordered pairs {{{minX, minY}, {maxX, maxY}, {dX, dY}}} is usually the key to determining the behavior of locators. {minX, minY} and {maxX, maxY} set the region. {dX, dY} sets the jump size: zero for unrestrained, any other positive number for the size of each hop. In the code below, {{{-.9, 0}, {1, 0}, {0, 0}}} sets the region and jumps for

问题 This seems to be a verified problem with SWING http://forums.sun.com/thread.jspa?threadID=385730 I'm currently trying to set the tooltip text of a tab in a JTabbedPane but when I do I can't actually select the tab anymore because the tooltip added a mouse listener that is consuming the events. Does anyone know of a workaround that allows me to keep my tooltips AND my mouseevents? Thank you. As per request here is my SSCCE package jtabbedbug; import javax.swing.JFrame; import javax.swing

问题 I've been trying to write a small utility that will modify the boundaries of where my mouse can go on the whole screen. I've used the the global mouse hook library that I found here (I'm using version 1), and then pass the mouse position information from the event it generates to my own function (just a test to see it working for now). internal void ProcessMouseEvent(System.Drawing.Point point) { Cursor.Position = new Point(50,50); } When running it, the mouse does appear to flash to the
