Horizontal Scrolling on React Component Using Vertical Mouse Wheel

由 五迷三道 提交于 2020-04-16 05:06:50
问题 I have a component that resizes into a horizontal row of bootstrap cards when in a smaller desktop window. For users without a horizontal mouse wheel and not using a touchpad, I would like to allow users to scroll horizontally using their vertical mouse wheel movements when hovering over this particular component. Here is the original StackOverflow issue I based my code off of: https://stackoverflow.com/a/15343916/8387497 Horizontal Scroll helper component: function horizontalScroll (event) {

How to make NumericUpDown ReadOnly

由 别说谁变了你拦得住时间么 提交于 2020-04-10 08:35:24
问题 I would like to make WinForms NumericUpDown control non-editable or at least spin control should be disabled. I tried setting the control readonly but using mouse scroll values are changing. Please help me to achieve this. 回答1: Try the following in order to set the numeric up/down as read-only: numericUpDown1.ReadOnly = true; numericUpDown1.Increment = 0; I hope it helps. 回答2: Another alternative is to subclass NumericUpDown and override the DownButton and UpButton methods so they return

Angular 4 - Added non-passive event listener to a scroll-blocking 'mousewheel' event.

问题 In my Angular 4 Project I get the following warning when I click on a date-picker or a select-option menu, running it in Google Chrome: [Violation] Added non-passive event listener to a scroll-blocking 'mousewheel' event. Consider marking event handler as 'passive' to make the page more responsive. I already saw an issue here on stack-overflow but that one was about 'touchstart', not 'mousewheel'. I don't really know what Code-examples I could give you because I don't know where the warning

杂记（隐藏滚动条及鼠标滚轮事件）

由 谁说胖子不能爱 提交于 2020-02-17 06:07:28
本次目的：要实现一个全屏网页，隐藏滚动条，当滚动 鼠标滚轮 时，屏幕像按帧数一样切屏而不是默认的滚动 1 隐藏滚动条 想要全屏演示隐藏滚动条，这里想到的方法是把 <body> 元素设置 overflow:hidden ，然后再设置包裹元素定义 width:102%; ， overflow-y:hidden; 以及 overflow-x:auto; ，并且使用 js 计算浏览器的高度再定义该包裹元素的高度与之相等，这些的目的是：想要在内实现一个内容可自行滚动的元素，然后将其的滚动条溢出 <body> 元素，而由于 <body> 元素定义了 overflow:hidden; ，所以就可以把滚动条隐藏掉，而由于设置包裹元素的高度等同于浏览器，因此 <body> 元素也可以无需生成滚动条。具体代码如下： <!DOCTYPE html> <html> <head> <meta charset="utf-8"> <style type="text/css"> *{ margin:0px; padding:0px; } .container{ width: 102%; overflow:hidden; overflow-y: auto; padding-right: 2%; height: 500px; } </style> <script type="text/javascript" src=

鼠标滚动事件 - onmousewheel

1.Jquery-MouseWheel 　　jquery默认是不支持支持鼠标滚轮事件(mousewheel) 　　jquery MouseWheel下载：https://github.com/jquery/jquery-mousewheel/blob/master/jquery.mousewheel.js 　　然后就可以使用mousewheel和unmousewheel事件函数了 　　 1 $('div.mousewheel_example').mousewheel(fn); 2 $('div.mousewheel_example').bind('mousewheel', fn); 　 　 Jquery MouseWheel兼容性 　　FireFox浏览器使用DOMMouseScroll事件,其他（包括IE6）都是使用onmousewheel事件； 　　FireFox中wheelDelta判断滚动方向，其值为120/-120，为负数的时候表示向下滚动，整数的时候向上滚动 　　其他：detail（属性）判断方向，返回值是3的整数倍(3/-3), 为正数表示向上滚动，负数向下滚动 　　opera:同时拥有wheelDelta和detail,其中“detail”属性返回值和FF中的wheelDelta相同 　　使用实例 1 // jquery 兼容的滚轮事件 2 $(document)

Disable Predictive Scrolling - Mousewheel (OnScroll) Event fires too often (Touchpad) - JS

由 随声附和 提交于 2020-01-22 12:24:44
问题 I am executing javascript onScroll. My code works great with any normal computer mouse, but when i use my notebooks touchpad, i encounter the following situation: my mouse fires (about 1 to 8) mousewheel events while the finger is moving the wheel. my touchpad fires a lot more (~60) mousewheel events while the two fingers are touching the pad and continues to fire after my fingers are up in the air again. I know this behavior from mobile touch devices. The Feature is called "Predictive Touch"

Make mouse tilt horizontal scrolling always repeat

由 僤鯓⒐⒋嵵緔 提交于 2020-01-15 12:40:08
问题 I'm designing a form with a horizontal scroll bar docked at the bottom. I wanted to add support for side-scrolling using mouse tilt buttons and found this solution which, after a bit of tinkering, seemed to do the trick – that is, while the form only had GDI graphics drawn on its surface. However, since then I've added some controls to the form and found that when the mouse is over any of them the tilt operation only fires once-at-a-time instead of repeatedly as it does when the mouse is over

Use mouse to scroll through tabs in JTabbedPane

由 不羁的心 提交于 2020-01-14 03:10:09
问题 I have a JTabbedPane in a scroll tab layout, so that all the tabs sit nicely on one row. Is there a way to allow the user to scroll through them with the mouse wheel, or is the only way to navigate the JTabbedPane.SCROLL_TAB_LAYOUT with the keyboard's and GUI's arrows and by clicking the tabs? 回答1: I did find an answer to this, after digging around Eclipse's autocomplete: use a MouseWheelListener for the JTabbedPane : JTabbedPane tabbedPane = new JTabbedPane(); tabbedPane.setTabLayoutPolicy

Qt 5 : Mouse Wheel event behaviour for zooming image

由 浪尽此生 提交于 2020-01-14 03:05:16
问题 I have a window, in which is a QGraphicsView, which will be displaying an image. I have implemented the wheelEvent(). My images are mostly going to be bigger than the window, so I get scroll bars in the window. What we normally observe when we rotate the wheel while viewing an image in Windows Photo Viewer is that when we move the wheel up (towards it's wire), the image zooms in and when we move it down (towards out body), the image zooms out. What I am getting instead is when I move the
