mouse

问题 I have connected 2 mice to PC and I wish one mouse to work as regular mouse and capture second mouse exclusively. First I was trying DirectInput. It showed 2 devices with word mouse in InstanceName. But only one device had DeviceType.Mouse and it was only really working device. When I was acquiring it was blocking both mice. Second I decided to create driver. I downloaded WinDDK. There is Mouse Filter driver sample. I was able to compile it. But I am not driver programmer. It is complex for

问题 How can I simulate the mouse click in a directx application? mouse_event and PostMessage with WM_LBUTTONDOWN don't work... so it must be something to do with the DirectInput I haven't found out nothing useful with google, so you may be knowing the answer... thanks in advance //update I wrote the text wrongly, what I want is to make the directx app believe that the mouse has just clicked, but without effectively using the mouse and without using SendInput or mouse_event, which need that the

问题 I'm looking for a jquery slider script that is able to right-left slide while I'm moving my mouse. Anyone knows that kind of script? I want to achieve an effect like this one but it should be scrolled horizontal, not vertical. 回答1: Do you mean something like this. It's a very basic thing that uses the jQuery UI Slider. I attach a handler to the mousemove event that just calculates what the value should be for the slider (based on the value of the mouse coordinates). $(function() { var range =

问题 In XUL or JavaScript, is there a way to move the mouse cursor to specified position? 回答1: The only time that Gecko moves the mouse is on Windows for the snap-to-default-button effect. This is used by XUL dialogs and wizards. The backend code doesn't actually check that you're giving it a button; any XUL control works. The mouse is moved to the centre of the element, if that point is on-screen, and the window is active. Normally the code checks that the system cursor snapping is enabled, but

问题 I have a program in LWJGL where I have a series of buttons. I'm trying to use Mouse.getEventButton() and Mouse.getEventButtonState() in order to figure out when the mouse is released , but neither seem to be working. After adding a few print statements for debugging, it seems that getEventButton() always returns 0 regardless of what the mouse is doing, and getEventButtonState() always returns false. All other mouse methods I've used so far have behaved normally. Any idea what might be going

问题 I am trying to draw at one place by dragging a mouse (for example, a circle in left upper quadrant) and have the figure appear at 4 places around center of canvas (including one right under the mouse cursor). I have tried following code: int x=0; int y=0; void setup(){ size(400, 400); background(255); translate(width/2, height/2); } void draw() { } void mouseDragged(){ translate(width/2, height/2); for(int i=0; i<4; i++){ rotate(PI/2); x= mouseX ; y=mouseY; line(x, y, mouseX, mouseY); } }

问题 I want to draw at one place by dragging the mouse and have the line drawn at 3 places around the center of canvas, including one under the cursor itself. I am using following code which does draw 3 lines but none of them is under the mouse cursor: void setup(){ size(300, 300); } void draw() { translate(width/2, height/2); if(mousePressed) for(int i=0; i<3; i++){ line(width/2 -mouseX, height/2 -mouseY, width/2 -pmouseX, height/2 -pmouseY); rotate(2*PI/3); }} How can I correct this code so that

问题 I'm writing a screen recording app for Windows in Delphi 7 and wish to know when the mouse pointer changes in my app (like from a normal pointer to a resize pointer, etc). Currently what I'm doing is painting the mouse pointer onto an in-memory bitmap everytime the mouse moves (and on a timer) and doing a pixel by pixel comparison of it with the last bitmap I painted. Though the comparision is fairly quick (about 2-5ms) because it's happening so often (every mouse move) it adds up. I figure

问题 I've been playing around with SDL for a few days now, and while I think I got the hang of it, I've run into a small problem with the menu. More specifically, the buttons in the menu. They work flawlessly when the mouse isn't moving that fast, but when I speed it up a bit (moving the cursor between the buttons, constantly making the button redraw from "normal" sprite to "mouse-over sprite"), it lags behind, sometimes doesn't update at all and small bugs start appearing. This is all my code

问题 I have a image on my html page and i want it to play a sound effect when i click on it. Here's the image code: <img src="images/button1.png" width="32" height="32" onclick="alert();"> I want to change the alert box into the sound effect that i load in. How do i do it? 回答1: Use SoundManager and will free up from a lot of headaches. Even more it will fallback nicely to flash if audio is not supported natively by browser. However if you don't want to relay on a third party library there is
