copy

问题 This question already has answers here : How to copy a python class? (8 answers) Closed 5 years ago . I have been playing with the deepcopy function and the copy function and I get the same issue with both of them. It is like the copy was a reference (or a pointer) instead of a proper copy. I am working with data records (classes) in Python, maybe it could be that.. I show you an example: >>> import copy >>> class player1: ... age = 23 ... score = 1 >>> class player2: ... age = 14 ... score =

问题 I have a weird bug that is popping up in my Ant build. The build works as such: build.xml calls a new buildTargets.xml file, and in that file most of the work is being done. buildTargets.xml creates a bunch of new files in gwt-out/htdocs/** and another directory staging/htdocs/**. Basically, files are being created in gwt-out/htdocs and then copied into staging/htdocs. The error is that only one file is not being copied, and I am getting a java.IO.FileNotFoundException (Access is denied)

问题 The iPhone 3.0 software added copy/paste, and native application can programmatically copy content to the clipboard. Is it possible to do the same, i.e. copy text to the clipboard, from JavaScript code running inside Safari on the iPhone? 回答1: On the desktop, copy/paste in websites typically seems to use an embedded Flash gizmo; obviously on the iPhone that's neither possible nor desirable. You might try one of the webView:shouldStartLoadWithRequest:navigationType: techniques discussed in

问题 I'm making a program which copies files in Qt. I want to know how can I use QProgressBar with bool QFile::copy(const QString & fileName, const QString & newName) . Is this even possible with copy function? Can the process of copying be paused? 回答1: You can't do this using the static QFile::copy() method. As Maciej stated before you need to write your own class. It should use two QFile objects, one for reading one for writing. Transfer the data in portions (e.g 1% of the entire file size) and

For example, the source is: a/b/c/foo.pdf d/e/f/bar.pdf I want the destination to be: a/b/c/x/foo.pdf d/e/f/x/foo.pdf Here is my target so far, but it doesn't appear to be doing anything: <copy todir="${dest.dir}"> <fileset dir="${src.dir}" casesensitive="yes"> <include name="**${file.separator}foo.pdf" /> </fileset> <mapper type="glob"

问题 Update: I think this is related to an issue with the windows git client msysgit.

问题 I have a groupox in a VB.NET winform app. The groupbox contains a few Labels, Textboxes and Checkboxes. This was created by simply dragging the controls out of VS toolbox. What I need to do is take the 1 Groupbox and at runtime create multiple Groupboxes to display based on user selection. Instead of dynamically creating the Groupboxes and other controls nested inside, is there a way to clone or copy the original one. Then I'd just change the properties. Label text, Textbox text, etc. And the

问题 How do I copy a selection of rows from a mySql table and insert with just the key value changed. Can I do a select and insert in same query? To be precise, what I want would look like this: Table cols, ID and ISO3 are keys: +----+------+-------------------------+ | ID | ISO3 | Text | +----+------+-------------------------+ | 1 | ENU | A text in english | | 2 | ENU | Another text in english | | 3 | ENU | bla bla | | 1 | JPN | 与えられた枠 | +----+------+-------------------------+ After the insert I
