I have a process which takes several seconds to load, and I want to create an animation in Java Swing until it finishes loading. I'd like to avoid using a typical ProgressBar and use a nice modern infinite progress like this one I'm aware of similar questions but this is strictly Java Swing related. Is there any library or example for this? 回答1: I'd recommend using the

How to have AJAX trigger the browser's loading indicator

点点圈 提交于 2019-11-26 22:51:01
问题 I'm making an ajax-enabled lab scheduling program, and some of the ajax operations aren't exactly quick. In Gmail, when you go to your inbox, send a message, etc. the browser acts like it's loading (In FF the stop button becomes enabled, the progress bar appears), but it's not on a new page, it's done via AJAX. How do they do this? I have a little spinny indicator, but it would be a nice touch to have the browser act like it's loading. Any ideas? 回答1: I think this is your answer. (Reverse

Java - Loading dlls by a relative path and hide them inside a jar

孤街浪徒 提交于 2019-11-26 22:33:30
PART 1 I am developing a Java application that should be release as a jar. This program depends on C++ external libraries called by JNI. To load them, I use the method System.load with an absolute path and this works fine. However, I really want to "hide" them inside the JAR, so I have created a package to collect them. This forces me to load an relative path - the package path. By this approach, I let the user run the JAR in any directory, without being worried about linking the DLLs or bored with a previous installation process. This throws the expected exception: Exception in thread "main"

Display a ‘loading’ message while a time consuming function is executed in Flask

爱⌒轻易说出口 提交于 2019-11-26 22:33:27
问题 I’m still relatively new to Flask, and a bit of a web noob in general, but I’ve had some good results so far. Right now I’ve got a form in which users enter a query, which is given to a function that can take anywhere between 5 and 30 seconds to return a result (looking up data with the Freebase API). The problem is that I can’t let the user know that their query is loading during this time, as the results page only loads once the function finishes its work. Is there a way I can display a

问题 My application contains lots of images. so it takes some time to load the application. I want to show a loading screen whhile the application is being loaded. How is it possible ? 回答1: Here's an example app that skeletons what your looking to do. Basically, the initial screen you push is a loading screen. During the initial startup sequence you need to spin up a new thread, do your loading stuff and then use invokeLater to 1) make sure your in the event dispatcher and 2) to push a new screen

隐身守侯 提交于 2019-11-26 20:21:02
问题 I have a simple screen with a start button. When the Start button is pressed, I want to go to a new Screen with a SurfaceView to show the Camera in. Everything works fine, but the Camera takes a while to load, and this gives me a black screen. I would like the new layout to load. And than start the camera after it has been loaded... Therefor, I do all Camera loading in a background thread, but still, I get a black screen... Here's my layout: <?xml version="1.0" encoding="utf-8"?>

Get image dimensions with Javascript before image has fully loaded

耗尽温柔 提交于 2019-11-26 20:03:51
I've read about various kinds of ways getting image dimensions once an image has fully loaded, but would it be possible to get the dimensions of any image once it just started to load? I haven't found much about this by searching (which makes me believe it's not possible), but the fact that a browser (in my case Firefox) shows the dimensions of any image I open up in a new tab right in the title after it just started loading the image gives me hope that there actually is a way and I just missed the right keywords to find it. You are right that one can get image dimensions before it's fully

Hive loading in partitioned table

大憨熊 提交于 2019-11-26 19:53:04
问题 I have a log file in HDFS, values are delimited by comma. For example: 2012-10-11 12:00,opened_browser,userid111,deviceid222 Now I want to load this file to Hive table which has columns "timestamp","action" and partitioned by "userid","deviceid". How can I ask Hive to take that last 2 columns in log file as partition for table? All examples e.g. "hive> LOAD DATA INPATH '/user/myname/kv2.txt' OVERWRITE INTO TABLE invites PARTITION (ds='2008-08-15');" require definition of partitions in the

Stop the browser “throbber of doom” while loading comet/server push iframe

让人想犯罪 __ 提交于 2019-11-26 19:47:22
When using Comet, or Ajax Long Pull techniques - an iframe is usually used. And while that iframe is waiting for the long connection to close, the browser is spinning its throbber (the progress/loading indicator). Some websites, for example etherpad.com, managed to make it stop. How do they do it? Evgeny After digging for a day and a night in the guts of the internets, here is what I came up with: server-sent events - Very cool, currently works only in Opera, but may be part of HTML5 and other browsers may support it sometime. Adds a new element tag with content-type of "application/x-dom

accessing UIImage properties without loading in memory the image

喜欢而已 提交于 2019-11-26 19:06:20
问题 As you know the iphone guidelines discourage loading uiimages that are greater than 1024x1024. The size of the images that i would have to load varies, and i would like to check the size of the image i am about to load; however using the .size property of uiimage requires the image to be laoded... which is exactly what i am trying to avoid. Is there something wrong in my reasoning or is there a solution to that? thank you all 回答1: As of iOS 4.0, the iOS SDK includes the CGImageSource...
