( I separate the field value in two __s16 variable, but is not a position). If anyone know a structure where I can access this, or a specific file to listen

问题 If I zoom in a page as far as it will go and move the mouse very slowly (a pixel at a time) across the page, the generated mousemove events' clientX / clientY values have no fractional part, and therefore lose precision. (Often, several mousemove events with the exact same co-ordinate values get fired in a row, because the mouse did move, but moved less than one whole CSS-pixel.) This is true for me on all browsers I have for Windows 10 -- Chrome, Firefox, Opera and Edge. MDN's "Browser

问题 I have a list of elements, when hovering one of these, I'd like to change my state. <ListElement onMouseOver={() => this.setState({data})}>Data</ListElement> Unfortunately, if I move my mouse over the list, my state changes several times in a quick succession. I'd like to delay the change on state, so that it waits like half a second before being fired. Is there a way to do so? 回答1: Here's a way you can delay your event by 500ms using a combination of onMouseEnter , onMouseLeave , and

问题 I'm currently working on a map generation program for a game I'm creating, and so I'm trying to be able to modify the individual tiles on the map using my mouse. I've successfully implemented the ability to click on a tile and change its value (from say a 4 way tile to a 2 way tile), but I am having trouble getting mouseDragged to work. According to the Java docs I've done the correct implementation of the mouseDragged interface into my MouseEventHandler, but I when I drag my mouse and move

问题 I'm pretty new to HTML and JS, but I'm trying to learn some of the basics. Now I'm experimenting with graphics. I'm trying to create two svg elements dynamically with JS and then move them individually with the mouse. I'm able to create them, and register the mouse events on them individually, but can't get them to move. To try to move there positions, in my dragging() function I assign the svg style.top and style.left to the value of the pointer. I can confirm in the JS console that the

问题 I want to read mouse wheel scroll events and then simulate them. I know I can simulate it using below code. #Scroll one up win32api.mouse_event(MOUSEEVENTF_WHEEL, x, y, 1, 0) #Scroll one down win32api.mouse_event(MOUSEEVENTF_WHEEL, x, y, -1, 0) However, I couldn't find a way to get whell scroll event using win32api in python. Is there anyway to detect wheel scroll up or down events? 回答1: If you need to get the global WM_MOUSEWHEEL message, you can use the SetWindowsHookEx function and with WH
