问题 I have an instantiated File object. I know it contains a picture format. I don't know where on the system the file is placed, other than the methods of File available to me getPath(), getAbsolutePath() etc. My question is: how can I instantiate a JavaFX Image object with the picture in my File ? 回答1: File provides a method to retrieve the URL for the file and the Image constructor expects a URL String . Image imageForFile = new Image(file.toURI().toURL().toExternalForm()); 回答2: Combining the

问题 i'm trying to get an array of all png files in a subdirectory of the Resources Folder. In my apps Resources Folder I have created a Folder named "images". This folder holds all the png-files I need to display. This is the way I tried to get the Path: NSString *imagepath = [NSString stringWithFormat:@"%@/%@",[[NSBundle mainBundle] bundlePath],@"images/"]; NSLog(@"Path to Images: %@", imagepath); NSArray * paths = [NSBundle pathsForResourcesOfType: @"png" inDirectory:imagepath]; NSMutableArray

问题 When I do 'open .profile' in the terminal I have the following: export PATH=$PATH:/usr/local/git/bin Now I installed node.js for Mac and it says, Make sure that /usr/local/bin is in your $PATH. How can I add /usr/local/bin to export PATH=$PATH:/usr/local/git/bin ? 回答1: export PATH=$PATH:/usr/local/git/bin:/usr/local/bin One note: you don't need quotation marks here because it's on the right hand side of an assignment, but in general, and especially on Macs with their tradition of spacy

问题 I'm working on a PHP script that generates a jpg wallpaper from an SVG-file according to the screen resolution of the visitor. The wallpaper consists of a circular gradient (rectangle) background and a path on top of it. How would you go about centering the path horizontally and vertically to the rectangle? Remember that the rectangle's size and proportions are not a constant. Should I separate the background and path to different svg files or is there an easy way to center paths? Maybe a

问题 As we know, windows accept both "\" and "/" as separator. But in python, "\" is used. For example, call os.path.join("foo","bar") , 'foo\\bar' will be returned. What's annoying is that there's an escape character, so you cannot just copy the path string and paste to your explorer location bar. I wonder is there any way to make python use "/" as default separator, I've tried change the value of os.path.sep and os.sep to "/" , but os.path.join still use "\\" . what's the right way? PS: I just

问题 is it possible to bind the Path property of a binding to another property? I want to realize this code: Text="{Binding Path={Binding Path=CurrentPath}}" So I can adjust dynamically to which Property my actual binding is refering. Thanks for your Help Jonny 回答1: As other posters have mentioned, you can only set a binding on a dependency property - which path is not. The underlying reason is that xaml is source code that gets compiled. At compile time the compiler has no idea what the value of

问题 I'm looking to take a string such as "/test/uri/to/heaven" and turn it into a multi-dimensional, nested array such as: array( 'var' => array( 'www' => array( 'vhosts' => array() ), ), ); Anyone got any pointers? I've had a look through Google and the search here, but I've not seen anything. 回答1: Here is a quick non recursive hack: $url = "/test/uri/to/heaven"; $parts = explode('/',$url); $arr = array(); while ($bottom = array_pop($parts)) { $arr = array($bottom => $arr); } var_dump($arr);

问题 when on "index.php" , I do require_once("/all_fns.php") . "all_fns.php" itself requires files with paths relative to all_fns.php (itself). My question is, should I write the paths on all_fns relative to all_fns.php or to index.php? This is all very confusing to me and wanted to get it straight. 回答1: They are treated as relative to index.php . If you need to reference a file relative to the include, use __DIR__."/relative/file.php"; 回答2: They are relative to the getcwd(). 回答3: in index.php

问题 Is there a way to change a valid and existing Hadoop Path object into a useful Java File object. Is there a nice way of doing this or do I need to bludgeon to code into submission? The more obvious approaches don't work, and it seems like it would be a common bit of code void func(Path p) { if (p.isAbsolute()) { File f = new File(p.toURI()); } } This doesn't work because Path::toURI() returns the "hdfs" identifier and Java's File(URI uri) constructor only recognizes the "file" identifier. Is

问题 Context : I need to call a Windows batch script which would update my PATH by adding another path ' xxx ' at the end of it, but: without any duplicate (if I add ' xxx ' to a PATH like ' aaa;xxx;bbb ', I need an updated PATH like ' aaa;bbb;xxx ') without any aggregation (I can call the script repeatedly without ending up with ' aaa;bbb;xxx;xxx;xxx;... ') What I have tried: The following function takes care of any duplicate and does the job :cleanAddPath -- remove %~1 from PATH, add it at the
