问题 So I am trieing to copy all the style that apply on one element ( class / id / tagName / attribute etc. ). So far I found out that I can copy the computed style of an element, Just one problem ... couldend apply it on outher element ;/ or diffrend way to copy all the style. (this is as far as i got :/ ) http://jsfiddle.net/8KdJd/2/ //queriks mode + minor changes to retrive the computed style function getCS(el) { if (el.currentStyle) var y = el.currentStyle; else if (window.getComputedStyle)

问题 I'm using Qt and have some real basic problems. I have created my own widget MyTest that have a variable obj . I need to set this variable obj from an object outside of the widget so that the variable is copied not just a pointer to another object. I get an error message and can't figure out how to do this basic stuff. This is the code I'm using: MyTest.h: class MyTest : public QWidget { Q_OBJECT public: void setObj(QObject &inobj); QObject obj; .... } MyTest.cpp: void MyTest::setObj(QObject

问题 My question is almost exactly this question: Clone textview to append it to a ViewGroup However, I was inflating a view, and then attempting to clone it at the object level for performance reasons (I don't want to parse XML every single time), so that answer doesn't help me. View.clone() is protected and it apparently doesn't have a copy constructor. Is there any way to do this? 回答1: You cannot clone views, the way to do it is to inflate your View every time. Note that the XML is compiled

问题 I have an ArrayList and I want to copy it exactly. I use utility classes when possible on the assumption that someone spent some time making it correct. So naturally, I end up with the Collections class which contains a copy method. Suppose I have the following: List<String> a = new ArrayList<String>(); a.add("a"); a.add("b"); a.add("c"); List<String> b = new ArrayList<String>(a.size()); Collections.copy(b,a); This fails because basically it thinks b isn't big enough to hold a . Yes I know b

问题 Why does the following does not copy the files to the destination folder? # find /home/shantanu/processed/ -name '*2011*.xml' -exec cp /home/shantanu/tosend {} \; cp: omitting directory `/home/shantanu/tosend' cp: omitting directory `/home/shantanu/tosend' cp: omitting directory `/home/shantanu/tosend' 回答1: If your intent is to copy the found files into /home/shantanu/tosend you have the order of the arguments to cp reversed: find /home/shantanu/processed/ -name '*2011*.xml' -exec cp "{}"

问题 I'm new to VBScript. I cannot find a way to copy files from one XP host to another using WMI in a VBS. The usual way of copying files (RPC - Remote Procedure Call, SMB, UNC) are not available to several hosts but WMI is available to all hosts, and I need to copy files from my admin host to a target Windows host. I thought I'd find some sample code out there but I've found no info on it. Haven't found anything telling me it can't be done, either. The source files are an executable and 'test1

问题 I want to have a button which selects the text in a textarea and copies it to the clipboard. I can't seem to find any solutions which work in all browsers and don't use flash. Surely this is doable? I've seen it all over the place but I guess they use flash, which I really want to stay away from if possible as some people don't have it. This is what I have so far - it just selects the text: function copyCode() { $("#output-code").focus(); $("#output-code").select(); } (The focus is not

问题 For a minimal working example, let's digitize a 2D array. numpy.digitize requires a 1D array: import numpy as np N = 200 A = np.random.random((N, N)) X = np.linspace(0, 1, 20) print np.digitize(A.ravel(), X).reshape((N, N)) Now the documentation says: ... A copy is made only if needed. How do I know if the ravel copy it is "needed" in this case? In general - is there a way I can determine if a particular operation creates a copy or a view? 回答1: This question is very similar to a question that
