阅读更多关于 A scrollable area with the overflow hidden but no scroll bar

问题 Is there a way of having an overflowing div that hides the overflow, doesn't have a scroll bar but is still scrollable (by means of the mouse wheel / touch input)? e.g. <!DOCTYPE html> <div id="longtext" style="width:100px; height:100px;"> Lorem ipsum.... </div> My CSS attempts have failed as overflow: hidden; stops the area being scrollable whilst overflow: auto / overflow: scroll has the scrollbars.

转自 http://hi.baidu.com/uecd/home " 一、首先来了解一下overflow overflow：内容溢出时的设置，可以设置对象是否显示滚动条， overflow-x：指水平方向内容溢出时的设置 overflow-y：指垂直方向内容溢出时的设置它们设置的值为visible、scroll、hidden、auto。 visible是默认值。使用这个值时，无论设置的"width"和"height"的值是多少，其中的内容无论是否超出范围都会被强制显示出来。 hidden效果与visible相反。任何超出"width"和"height"的内容都会不可见。 scroll无论内容是否超出范围，都会显示滚动条。 auto当内容超出范围时，自动显示滚动条，否则不显示。例如： 1.浏览器窗口不出现滚动条： a.没有水平滚动条：<body style="overflow-x:hidden"> b.没有垂直滚动条：<body style="overflow-y:hidden"> c.没有滚动条：<body style="overflow-x:hidden;overflow-y:hidden"> 或<body style="overflow:hidden"> 2.让多行的文本隐藏滚动条： a.没有水平滚动条：<textarea style="overflow-x:hidden"

What are the equivalents of Swifts integer “Overflow Operators” &*, &+ and &- in Java?

阅读更多关于 What are the equivalents of Swifts integer “Overflow Operators” &*, &+ and &- in Java?

问题 Swift offers so called "Overflow Operators" &*, *+, &- for integer arithmetics (Swift Advanced Operators). They are designed to truncate the number of available bits when performing an operation that would lead to an overflow. For example: var unsignedOverflow = UInt8.max // --> 255 unsignedOverflow = unsignedOverflow &+ 1 // --> 0, instead of overflow Since Java doesn't support unsigned integers, there is probably not a real equivalent. In Java 8, there are functions like Integer

TextBox ScrollToHorizontalOffset will not scroll after text is long enough

阅读更多关于 TextBox ScrollToHorizontalOffset will not scroll after text is long enough

问题 I have a textbox (textBox1 as an example) to which i'm periodically appending a character (every second or so). I wish to make it so that when the text gets too long to fit in the textbox the overflow will actually go towards the left of the textbox even when it's not focused instead of the normal behaviour which is to the right, this way the last character will always be shown. The way I've done it is when I'm adding the character i'm also doing: textBox1.ScrollToHorizontalOffset(textBox1
