  • DoDragDrop disables MouseMove Events

    - by stefan.at.wpf
    After having started a Drag & Drop operation by DragDrop.DoDragDrop(...) no more MouseMove Events are fired. I even tried AddHandler(Window.MouseMoveEvent, new MouseEventHandler(myControl_MouseMove), true); where the last parameter means I even opt in for handled events. No chance, seems like the MouseMove Event is never fired at all! Any way to still get MouseMove Events while using Drag & Drop? I'd like to Drag & Drop a control, while dragging this control it shall follow the mouse pointer. Any idea how to do this in this case?

  • MouseMove sensibility

    - by serhio
    I use MouseMove event to move objects(say labels). simple principle(schematic): OnMouseMove(e MouseEventArgs) deltaX = e.X - lastX foreach label in labels label.Location.X += deltaX lastX = e.X Now, when I have one label there is no problem. Once the labels number increase, I start to see the labels traces along the moving trajectory. Is there a way to prevent this kind of traces? tried label.Visible = false label.Location.X += deltaX label.Visible = true does not help.

  • jQuery mousemove performance

    - by Colby77
    Hi, When I bind a mousemove event to an element it is working smoothly with every browser except Internet Explorer. With IE the CPU usage is way too much and some associated things (eg. tooltip) are ugly. Is there any way I could rid of the performance problem? (yeah I know, don't use IE :))

  • Silverlight MouseMove: find missing points during a movement

    - by Jalfp
    In an application in Silverlight I'm working on, I need to track the moves of the mouse. My problem is that using the MouseMove event, I don't have a continuous set of points if the user moves the mouse fast enough (if I add each point in a list I can have (10,10) en then (20,20)...) I'd like to have ALL points where the mouse has been during the move. Do you have any idea ?

  • $().mouseMove <-- Empty selector in jQuery 1.4

    - by Matrym
    The following bit of code breaks in the upgrade to jquery 1.4: $().mousemove( function (e) { defaults.mouseX = e.pageX; defaults.mouseY = e.pageY; }); }; What appeared to be a reasonable fix was adding "html" as the selector, ex: $("html"). The fix works fine - except now when the user mouses off the page, it doesn't register the mouse position beyond the boundaries. When attempting to use the mouse position for a drag, for example, the amount of movement beyond the screen is really important. Anyone got any ideas? Thanks in advance.

  • jQuery Drag/Drop problem: mousemove Event not binding for some elements

    - by saturdayplace
    Using the latest jQuery/UI that are hosted at Google. I've got the following markup: <ul id="tree"> <li><a href="1/">One</a></li> <li><a href="2/">Two</a></li> </ul> And the following javascript: $(document).ready(function(){ // Droppable callbacks function dragOver(overEvent, ui_object) { $(this).mousemove(function(moveEvent){ console.log("moved over", this); }); } function drop_deactivate() { $(this).unbind(); } function drag_out() { $(this).unbind(); } // Actual dragging $("#treeContainer li").draggable({ revert: true, revertDuration: 0 }); // Actuall dropping $("a").droppable({ tolerance: "pointer", over: dragOver, deactivate: drop_deactivate, out: drag_out }); }); If I drag the first li down over the second, the mousemove function fires (and firebug logs the output). But if I drag the second li up over the first, the mousemove function doesn't fire. You can see this live at http://jsbin.com/ivala. Is there a reason for this? Should I be trapping the mousemove event in some other way? Edit: It appears as thought the mousemove() event isn't binding for earlier elements than the one currently being dragged (should be bound upon their mouseover).

  • Webkit and Safari fire mousemove even when mouse doesn't move

    - by Roel
    I've read about issues where the mousemove event is fired twice in Safari/Webkit, but the problem I'm facing is that mousemove fires even when the mouse is not moved. That is: it already fires when the mouse cursor is positioned above the context that the event is attached to when the page is loaded/refreshed. And because I'm attaching it to 'document' (entire viewport of the browser), it fires right away in Safari. I've tried to attach it to to html element, to the body and to a wrapper div. No change. $(document).bind('mousemove', function() { alert('Mouse moved!'); $(document).unbind('mousemove'); }); Is does work ok in other browsers. Anyone seeing what I'm doing wrong? Thanks.

  • Binding mousemove within mousedown function with jQuery

    - by colinjameswebb
    I am trying to bind a mousemove event to a div when the left mousebutton is down, and unbind when it is released. This code should be fairly self-explainatory. function handleMouseDown(e, sbar){ if (e.button == 0){ console.log(sbar); //firebug sbar.bind('mousemove', function(event){ handleMouseMove(event, sbar); }); } } function handleMouseUp(e, sbar){ sbar.unbind('mousemove'); } function handleMouseMove(e, sbar){ // not sure it this will work yet, but unimportant $(".position").html(e.pageX); } $(document).ready(function (){ var statusbar = $(".statusbar"); statusbar.mousedown(function(event){ handleMouseDown(event, this); }); statusbar.mouseup(function(event){ handleMouseUp(event, this); }); }); The important part of the HTML looks like this <div id="main"> <div class="statusbar"> <p class="position"></p> </div> </div> Firebug says that the bind methods are undefined on the variable sbar within handleMouseDown and handleMouseUp. The firebug console prints out <div class="statusbar"> for the line commented //firebug. I'm doing something wrong, probably when binding the mousedown and mouseup... but what?! I'm using jQuery v1.4.2, if that helps?

  • Global mouseMove

    - by Jacob Kofoed
    I have made the following javascript to be used in my jQuery based website. What it does, is to move a slider up/down, and scale the item above higher/smaller. Everything works fine, but since the slider is only a few pixels in height, and the move event is a bit slow (it does not trigger for every pixel) so when I move the mouse fast, the slider can't hold on and the mouse get's out of the slider item. The mouseMove event won't be triggered no more since it is bound to the slider. I guess everything could be fixed by setting the mouseMove global to the whole site, but it won't work, or at least I don't know how to make that work. Should it be bound to document, or body? here is my current code for the slider: $.fn.resize = function (itemToResize) { MinSize = 100; MaxSize = 800; pageYstart = 0; sliderMoveing = false; nuskriverHeight = 0; this.mousedown(function(e) { pageYstart=e.pageY; sliderMoveing = true nuskriverHeight = parseFloat((itemToResize).css('height')); }); this.mouseup(function() { sliderMoveing = false }); this.mousemove(function(e) { if (sliderMoveing) { (itemToResize).css('height', (nuskriverHeight + (e.pageY - pageYstart))); if (parseFloat( (itemToResize).css('height')) > MaxSize) { (itemToResize).css('height', MaxSize) }; if (parseFloat( (itemToResize).css('height')) < MinSize) { (itemToResize).css('height', MinSize) }; }; }); }; Thanks for any help, is much appreciated

  • Mouseup not working after mousemove on img

    - by leyou
    I'm trying to do a simple drag script. The idea is to save the position when the mouse is down, update the view while the mouse is moving, and stop when mouse is up. Problem, mouseup event isn't working properly. See the code: var target = $('a') var pos = 0; var dragging = false; $(document).mousedown(function(e) { pos=e.pageX; dragging = true }) $(document).mouseup(function() { dragging = false }) $(document).mousemove(function(e) { if(dragging){ target.css('left', e.pageX-pos); } }) ? Why mouseup works with a "a" tag: http://jsfiddle.net/leyou/c3TrG/1/ And why mouseup doesn't work with a "img" tag: http://jsfiddle.net/leyou/eNwzv/ Just try to drag them horizontally. Same probleme on ie9, ff and chrome.

  • jquery custom drag and drop

    - by samlochner
    I am trying to create functionality similar to drag and drop. I need to create my own as there will be some significant differences to the drag and drop in the jquery UI. I would like to have mousemove being called repeatedly at all times, and mousedown called every time the mouse is pressed. So I have the following code: $(document).bind('mousemove',function(e){ $("#coords").text("e.pageX: " + e.pageX + ", e.pageY: " + e.pageY); }); $(document).bind('mousedown',function(e){ }); ('coords' is the id of a div) As I move the mouse, coordinates are reported correctly in 'coords'. If I depress a mouse button and then move the mouse, coordinates are still reported correctly. But if I depress a mouse button on an image and then move the mouse, coordinates are reported correctly for a few sets, and then they seize up! Why is this happening and how can I fix it? Thanks, Sam

  • Combining mousedown and mousemove events together with Javascript (JQUERY?)

    - by webzide
    Dear experts, I would like to combine a the mousedown and mousemove and mouseup events together. Basically the application of this would be making a UI for selecting elements. Like selecting icons in windows when the mouse is clicked down and as you move it, a dotted border dynamically moves with it. I know this is possible with the predefined UI of Jquery. But I am building a web application that requires the integration of this and would like to know the technique. I spend hours on this and it just doesn't work. here's is the code i have so far and the logic behind it: $(document).bind('mousedown', function (evt) { evt = (evt) ? evt : event; startX = evt.clientX; startY = evt.clientY; div = document.createElement("div"); div.style.position = "absolute"; div.style.left = startX + "px"; div.style.top = startY + "px"; div.style.border = "1px dotted #DDDDDD"; $(document).bind('mousemove', function(evt){ evt=(evt) ? evt: event; alert("TESTING OF THIS WORKS"); }); }); $(document).bind('mouseup',function(evt) { var evt = (evt) ? evt : event; var endX = evt.clientX; var endY = evt.clientY; difX = (endX - startX); difY = (endY - startY) if ((difX || difY) > 0) { div.style.width = difX + "px"; div.style.height = difY + "px"; document.body.appendChild(div); } $(this).unbind('mousemove'); }); As you can see I have placed an event binding of mousemove into the event function of mousedown so that it can only be invoked when the mouse is down. but the problem is, once that event is binded, it does not come off. The borders does not move dynamically as expected. Maybe my logic is entirely messed up. If anyone could point me the the right direction that would be great. THanks in advance.

  • Fixed mouse pointer with jQuery draggable

    - by MikeWyatt
    I'm building a little game in HTML5. The canvas element is a viewport into the game world. The user can move the viewport's position in the world by clicking and dragging with the mouse on a small icon. The problem is that the scrolling stops when the mouse pointer hits the edge of the screen. In all likelihood, that will limit scrolling in one of the directions severely, since the icon will be in one of the corners of the page. The only technical solution I can think of would be to somehow fix the mouse pointer's position on the icon and detect the relative movement each frame. Basically I would just reset the pointer position back to the center of the icon after each drag event. Unfortunately, I'm fairly positive that this is not possible. Playing with the user's pointer is a big no-no from a usability and security standpoint. So, is there any other way to do what I want? I'm primarily looking for technical ideas here, but suggestions for a more appropriate interface would also be welcome.

  • How should I link two items with MouseMovementListeners?

    - by user1708810
    I'm working on a program that will display two "views" of the same set of items. So I need to have something set up so that when the top down view is changed, the side view is updated (and vice versa). Here's a brief outline of the relevant code so you can get an idea of my structure so far: public class DraggableComponent extends JComponent { //Contains code for MouseMovementListener that makes the item draggable } public class ItemGraphic extends DraggableComponent { //Code to render the graphic } public class Item { private ItemGraphic topGraphic; private ItemGraphic sideGraphic; } I'm able to get each graphic to display fine in my GUI. I can also independently drag each graphic. I'm missing the "linking." Some ideas I've been thinking about: Have one listener for the whole GUI. Loop through each Item and if the cursor is within the bounds of either graphic, move the other graphic. I'm concerned about the efficiency of this method. Multiple "paired" listeners (not quite sure how this would work, but the idea is that each graphic would have a listener for the other paired graphic)

  • Possible to manipulate UI elements via dispatchEvent()?

    - by rinogo
    Hi all! I'm trying to manually dispatch events on a textfield so I can manipulate it indirectly via code (e.g. place cursor at a given set of x/y coordinates). However, my events seem to have no effect. I've written a test to experiment with this phenomenon: package sandbox { import flash.display.Sprite; import flash.events.MouseEvent; import flash.text.TextField; import flash.text.TextFieldType; import flash.text.TextFieldAutoSize; import flash.utils.setTimeout; public class Test extends Sprite { private var tf:TextField; private var tf2:TextField; public function Test() { super(); tf = new TextField(); tf.text = 'Interact here'; tf.type = TextFieldType.INPUT; addChild(tf); tf2 = new TextField(); tf2.text = 'Same events replayed with five second delay here'; tf2.autoSize = TextFieldAutoSize.LEFT; tf2.type = TextFieldType.INPUT; tf2.y = 30; addChild(tf2); tf.addEventListener(MouseEvent.CLICK, mouseListener); tf.addEventListener(MouseEvent.DOUBLE_CLICK, mouseListener); tf.addEventListener(MouseEvent.MOUSE_DOWN, mouseListener); tf.addEventListener(MouseEvent.MOUSE_MOVE, mouseListener); tf.addEventListener(MouseEvent.MOUSE_OUT, mouseListener); tf.addEventListener(MouseEvent.MOUSE_OVER, mouseListener); tf.addEventListener(MouseEvent.MOUSE_UP, mouseListener); tf.addEventListener(MouseEvent.MOUSE_WHEEL, mouseListener); tf.addEventListener(MouseEvent.ROLL_OUT, mouseListener); tf.addEventListener(MouseEvent.ROLL_OVER, mouseListener); } private function mouseListener(event:MouseEvent):void { //trace(event); setTimeout(function():void {trace(event); tf2.dispatchEvent(event);}, 5000); } } } Essentially, all this test does is to use setTimeout to effectively 'record' events on TextField tf and replay them five seconds later on TextField tf2. When an event is dispatched on tf2, it is traced to the console output. The console output upon running this program and clicking on tf is: [MouseEvent type="mouseMove" bubbles=true cancelable=false eventPhase=3 localX=0 localY=1 stageX=0 stageY=1 relatedObject=null ctrlKey=false altKey=false shiftKey=false delta=0] [MouseEvent type="rollOver" bubbles=false cancelable=false eventPhase=2 localX=0 localY=1 stageX=0 stageY=1 relatedObject=null ctrlKey=false altKey=false shiftKey=false delta=0] [MouseEvent type="mouseOver" bubbles=true cancelable=false eventPhase=3 localX=0 localY=1 stageX=0 stageY=1 relatedObject=null ctrlKey=false altKey=false shiftKey=false delta=0] [MouseEvent type="mouseMove" bubbles=true cancelable=false eventPhase=3 localX=2 localY=1 stageX=2 stageY=1 relatedObject=null ctrlKey=false altKey=false shiftKey=false delta=0] [MouseEvent type="mouseMove" bubbles=true cancelable=false eventPhase=3 localX=2 localY=2 stageX=2 stageY=2 relatedObject=null ctrlKey=false altKey=false shiftKey=false delta=0] [MouseEvent type="mouseMove" bubbles=true cancelable=false eventPhase=3 localX=2 localY=3 stageX=2 stageY=3 relatedObject=null ctrlKey=false altKey=false shiftKey=false delta=0] [MouseEvent type="mouseMove" bubbles=true cancelable=false eventPhase=3 localX=3 localY=3 stageX=3 stageY=3 relatedObject=null ctrlKey=false altKey=false shiftKey=false delta=0] [MouseEvent type="mouseMove" bubbles=true cancelable=false eventPhase=3 localX=5 localY=3 stageX=5 stageY=3 relatedObject=null ctrlKey=false altKey=false shiftKey=false delta=0] [MouseEvent type="mouseMove" bubbles=true cancelable=false eventPhase=3 localX=6 localY=5 stageX=6 stageY=5 relatedObject=null ctrlKey=false altKey=false shiftKey=false delta=0] [MouseEvent type="mouseMove" bubbles=true cancelable=false eventPhase=3 localX=7 localY=5 stageX=7 stageY=5 relatedObject=null ctrlKey=false altKey=false shiftKey=false delta=0] [MouseEvent type="mouseMove" bubbles=true cancelable=false eventPhase=3 localX=9 localY=5 stageX=9 stageY=5 relatedObject=null ctrlKey=false altKey=false shiftKey=false delta=0] [MouseEvent type="mouseMove" bubbles=true cancelable=false eventPhase=3 localX=10 localY=5 stageX=10 stageY=5 relatedObject=null ctrlKey=false altKey=false shiftKey=false delta=0] [MouseEvent type="mouseMove" bubbles=true cancelable=false eventPhase=3 localX=11 localY=5 stageX=11 stageY=5 relatedObject=null ctrlKey=false altKey=false shiftKey=false delta=0] [MouseEvent type="mouseMove" bubbles=true cancelable=false eventPhase=3 localX=12 localY=5 stageX=12 stageY=5 relatedObject=null ctrlKey=false altKey=false shiftKey=false delta=0] [MouseEvent type="mouseDown" bubbles=true cancelable=false eventPhase=3 localX=12 localY=5 stageX=12 stageY=5 relatedObject=null ctrlKey=false altKey=false shiftKey=false delta=0] [MouseEvent type="mouseUp" bubbles=true cancelable=false eventPhase=3 localX=12 localY=5 stageX=12 stageY=5 relatedObject=null ctrlKey=false altKey=false shiftKey=false delta=0] [MouseEvent type="click" bubbles=true cancelable=false eventPhase=3 localX=12 localY=5 stageX=12 stageY=5 relatedObject=null ctrlKey=false altKey=false shiftKey=false delta=0] [MouseEvent type="mouseMove" bubbles=true cancelable=false eventPhase=3 localX=10 localY=4 stageX=10 stageY=4 relatedObject=null ctrlKey=false altKey=false shiftKey=false delta=0] [MouseEvent type="mouseMove" bubbles=true cancelable=false eventPhase=3 localX=9 localY=2 stageX=9 stageY=2 relatedObject=null ctrlKey=false altKey=false shiftKey=false delta=0] [MouseEvent type="mouseMove" bubbles=true cancelable=false eventPhase=3 localX=9 localY=1 stageX=9 stageY=1 relatedObject=null ctrlKey=false altKey=false shiftKey=false delta=0] [MouseEvent type="mouseOut" bubbles=true cancelable=false eventPhase=3 localX=-1 localY=-1 stageX=-1 stageY=-1 relatedObject=null ctrlKey=false altKey=false shiftKey=false delta=0] [MouseEvent type="rollOut" bubbles=false cancelable=false eventPhase=2 localX=-1 localY=-1 stageX=-1 stageY=-1 relatedObject=null ctrlKey=false altKey=false shiftKey=false delta=0] As we can see, the events are being captured and replayed successfully. However, no change occurs in tf2 - the mouse cursor does not appear in tf2 as we would expect. In fact, the cursor remains in tf even after the tf2 events are dispatched. Please help! Thanks, -Rich

  • How to simulate mousemove event from one window to another?

    - by Gohan
    Hello, I am trying to Create an empty window, which process the WM_MOUSEMOVE message in WinProc: case WM_MOUSEMOVE: { HWND otherHwnd = HWND(0x000608FC); POINT pt = {LOWORD(lParam), HIWORD(lParam)}; ClientToScreen(otherHwnd, &pt); PostMessage(otherHwnd, WM_TIMER, WPARAM(4096), 0); PostMessage(otherHwnd, message, wParam, lParam); SendMessage(otherHwnd, WM_NCHITTEST, NULL, (LPARAM)MAKELONG(pt.x, pt.y)); SendMessage(otherHwnd, WM_NCHITTEST, NULL, (LPARAM)MAKELONG(pt.x, pt.y)); SendMessage(otherHwnd, WM_NCHITTEST, NULL, (LPARAM)MAKELONG(pt.x, pt.y)); SendMessage(otherHwnd, WM_SETCURSOR, WPARAM(otherHwnd), (LPARAM)MAKELONG(HTCLIENT, WM_MOUSEMOVE)); break; } I hope I can hover the hyberlink in IE, but result is the hyberlink only be showed as hover style in a very short time, then it turn to normal, and then again hover, then normal.

  • jQuery Manual Resizable DIV

    - by JC
    Hi, I'm trying to create a resizable div without using jQuery's interface library. var myY = 0; var mouseDown = false; var originalHeight = 0; function resize(e){ if(mouseDown == true){ $("#cooldiv").height(originalHeight+e.pageY-myY); } } $(document).ready(function(){ $().mouseup(function(e){ myY = 0; mouseDown = false; originalHeight = 0; $().unbind("mousemove", resize); }); $("#resizeBar").mousedown(function(e){ myY = e.pageY; originalHeight = $("#cooldiv").height(); mouseDown = true; $().bind("mousemove", resize); }); }); ... <div id="cooldiv" style="width: 500px; height: 300px; background-color: #cccccc; position: relative;"> <div id="resizeBar" style="height: 10px; width: 500px; background-color: #aaaaaa; position: absolute; bottom: 0;"></div> </div> The first resize works fine(i.e. mousedown, mousemove then mouseup), but on subsequent (mousedown+mousemove)s, the browser attempts to drag the whole resizeBar div instead of properly resizing its parent container. On mouseup, the div then starts resizing "cooldiv" on mousemove without any mousedown required, until a further click of the mouse. These problems don't show up in Internet Explorer.

  • Attaching an event to an Iframe that contains more iframes

    - by Oscar Godson
    I have an editor which is in my window that contains a wrapping iframe and then 2 more iframes inside like (the HTML inside the <iframe> element is inserted via write() in JS, not hardcoded like this): <iframe class="parent"> <div class="wrapper"> <iframe class="editor"></iframe> <iframe class="previewer"></iframe> </div> </iframe> One is an editor, the other is a previewer. The first one that contains the two (we'll call this the parent) has an eventListener for mousemove attached to it, but nothing is firing. If i add a 5px border for example, the event will fire when I move my mouse on the border of the parent, but not when i hover over the middle which contains the editor or previewer (previewer is display:none while the editor is visible, and vice versa). So, the blue area in the following i can mousemove, but the rest I can't. It's most likely because of the stacking order, but how can I attach an event to fire on the entire frame? I need mousemove because on mousemove I display a menu in the bottom right. I want the same menu to display whether or not the editor or the previewer is visible.

  • What's the best way to structure this Linq-to-Events Drag & Drop code?

    I am trying to handle a drag & drop interaction, which involves mouse down, mouse move, and mouse up. Here is a simplified repro of my solution that: on mouse down, creates an ellipse and adds it to a canvas on mouse move, repositions the ellipse to follow the mouse on mouse up, changes the colour of the canvas so that it's obvious which one you're dragging. var mouseDown = Observable.FromEvent<MouseButtonEventArgs>(canvas, "MouseLeftButtonDown"); var mouseUp = Observable.FromEvent<MouseButtonEventArgs>(canvas, "MouseLeftButtonUp"); var mouseMove = Observable.FromEvent<MouseEventArgs>(canvas, "MouseMove"); Ellipse ellipse = null; var q = from start in mouseDown.Do(x => { // handle mousedown by creating a red ellipse, // adding it to the canvas at the right position ellipse = new Ellipse() { Width = 10, Height = 10, Fill = Brushes.Red }; Point position = x.EventArgs.GetPosition(canvas); Canvas.SetLeft(ellipse, position.X); Canvas.SetTop(ellipse, position.Y); canvas.Children.Add(ellipse); }) from delta in mouseMove.Until(mouseUp.Do(x => { // handle mouse up by making the ellipse green ellipse.Fill = Brushes.Green; })) select delta; q.Subscribe(x => { // handle mouse move by repositioning ellipse Point position = x.EventArgs.GetPosition(canvas); Canvas.SetLeft(ellipse, position.X); Canvas.SetTop(ellipse, position.Y); }); the XAML is simply <Canvas x:Name="canvas"/> There's a few things I don't like about this code, and I need help refactoring it :) First of all: the mousedown and mouseup callbacks are specified as side effects. If two subscriptions are made to q, they will happen twice. Second, the mouseup callback is specified before the mousemove callback. This makes it a bit hard to read. Thirdly, the reference to the ellipse seems to be in a silly place. If there's two subscriptions, that variable reference will get overwritten quite quickly. I'm sure that there should be some way we can leverage the let keyword to introduce a variable to the linq expression that will mean the correct ellipse reference is available to both the mouse move and mouse up handlers How would you write this code?

  • Prevent an element from being the target in a document mouseover

    - by Sander
    I'm building an firebug-like inspection tool for my page. When the mouse enters an element, the element should be highlighted. Now I'm creating an element which I position absolute on top of the target element, this however means the next mousemove event (which is bound to the document) will fire with the actual "highlight element" as the target. Is there a way to prevent the "highlight element" from being the target element in the mousemove event? The element already has a transparant background.
