问题 I'd like to use loop while left mousebutton is pressed: private void Loop_MouseDown(object sender, MouseEventArgs e) { while (e.Button==MouseButtons.Left) { //Loop } } I can't use solution from this thread: C# how to loop while mouse button is held down because I'm sending via RS232 data and using timer with it's own interval doesn't work. Also any solution from this topic doesn't work for me. It can't also work one like here: if (e.Button == MouseButtons.Left) { //loop } This solution also

问题 I'm new at using actionListener and mouselistner . I want to track the Mouse movements and connect the dots as I go. So it will be one continuous line. I am using the MouseMotionListener every time I move the mouse across the screen and get a new set of points. I am not using mousePressed or mouseReleased . Everytime I move the mouse, I can get every point of where my mouse's position is on my JPanel to show up on my results window, but in order to draw the line between two points, I'm not

问题 I'm having this issue with the html5 canvas. I'm using EaselJS to load in images. http://www.createjs.com/Docs/EaselJS/Bitmap.html But when I add any kind of mouse events (onClick, onMouseOver, onMouseOut) on a parentcontainer of the image, from the moment i move my mouse, EaselJS spams this error: uncaught exception: An error has occurred. This is most likely due to security restrictions on reading canvas pixel data with local or cross-domain images. It's running on an IIS server and the

问题 I'm trying to make an interactive GUI but I need to move a certain object whenever that rectangle is clicked + dragged. Basically I wanna know whether a rectangle, that has been affine transformed, contains a specific point (x, y). Is there a way to do this? I have tried using contains() method but it doesn't work for a rectangle that has been affine transformed. I checked the Java tutorials but the user interactive GUIs don't use affine transformation. Can someone point me to a tutorial that

问题 I did something like scrollbar from Control . Everything is fine, but when cursor leaves control area, OnMouseMove is not received anymore. When you use standard windows scrollbar, you can use it even if mouse cursor is outside the control's surface. To avoid this, the only idea I have, is get cursor position from screen, then calculate scrollbar position on screen, and use timer or something to update my Control . But it sounds very hard and ugly. Any idea how to fix it? EDIT: I meant

问题 How can I find the index of a point on click on and add it to end of an array, list or vector? h=figure; image(result); locx = []; locy = []; while (ishandle(h)) pos = get(0, 'PointerLocation'); locx(end + 1) = pos(1); locy(end + 1) = pos(2); pause(1); end While I have only clicked on two points to see their x,y and index, many x locations has been saved in locx array. Please suggest solution and fixes: locx = Columns 1 through 16 635 1116 231 758 771 591 596 46 116 116 116 1362 852 498 1920

问题 I've got a movieclip that I'm using as a button. Within this movieclip is a large shadow that shows when the button is moused over. My problem is that this shadow is effecting the mouseovers and causing a much larger "catch" area for the mouseOver and mouseOut events than I want. I've tried disabling mouse events on that child and as many combinations of mouseEnabled and mouseChildren I can think of. Is it possible to prevent certain elements effecting the mouseover properties of it's parent,

问题 I have this interface I want to build using Effect.Move from scriptaculous (with Prototype, of course). When the top div is triggered on a mouseover, a span tag is to move 50 pixels to the left - and reset without movement to the original location on mouseout. The problem is, any time this div element is entered from a child element, the element I want moved moves an additional 50 pixels. I've tried using relatedTarget and toElement to stop this event from propogating, but to no avail. Here
