Fullscreen feature for Java Apps on OSX Lion

阅读更多关于 Fullscreen feature for Java Apps on OSX Lion

How can I (natively) implement the fullscreen feature of OSX Lion in a Java application? The current answers given incorporate a good method for achieving a sort-of-fullscreen feature. I've read that Eclipse may be able to use the "native" fullscreen feature of Lion. That's what I'm asking about. Dyorgio I found this on Apple's Java release notes: Mac OS X 10.7 Lion Fullscreen Support Java applications on Lion can now opt into the Fullscreen window feature per-window. Developers can use the com.apple.eawt.FullScreenUtilities class to mark windows as able to be full screened, and the com.apple

I am trying to do a simple maven build with IntelliJ IDEA 10.5.1 on OS X Lion and am getting the following error: Error running my-app [package]: No valid Maven installation found. Either set the home directory in the configuration dialog or set the M2_HOME environment variable on your system. I have set M2_HOME to the following, but I am still having issues. And yes, I did restart IntelliJ. $ echo $M2_HOME /usr/share/maven I then manually entered the path to maven in IntelliJ's Maven Settings for the project. This is not something that I want to do for every project, so is there something I

问题 [edit] I was troubleshooting problems with my development environment when I noticed one of my problems was the dependency on ImageMagick, since it's a vital part of my app. After upgrading to OS X Lion (10.7) i no longer had ImageMagick available, i then tried installing again using MacPorts without success, i then installed from source, and the install wasn't very successfully i had convert and identify but it output error messages that i unfortunately dont have anymore, i by some strange

How can I eliminate slow resolving/loading of localhost/virtualhost (a 2-3 second lag) on Mac OS X Lion?

阅读更多关于 How can I eliminate slow resolving/loading of localhost/virtualhost (a 2-3 second lag) on Mac OS X Lion?

问题 Since setting up my development environments on Mac OS X Lion (brand new macbook air purchased in January 2012), I have noticed that resolving to a virtual host is very slow (around 3 seconds) the first time but after that is fast as long as I continue loading it regularly. If I leave it untouched for a couple of minutes and then reload again, the first reload is (again) painfully slow; seems like something is being cached. As can be seen below I am not using the .local TLD. My setup: Apache

Can anyone provide me some detailed guide how to compile OpenCV 2.3.1 on OS X Lion with Xcode?

Linking troubles with boost::program_options on OSX using LLVM

阅读更多关于 Linking troubles with boost::program_options on OSX using LLVM

问题 I'm having trouble getting through the linking phase in my C++ program due to problems with Boost 1.49. I have switched to C++ ( -std=c++11 -libc=libc++ ) which works fine for another piece of code (which also uses boost). Boost was installed using homebrew with: brew install boost --universal --with-mpi --with-icu The trouble starts with boost::program_options . I get the link errors like this: "boost::program_options::validate(boost::any&, std::__1::vector<std::__1::basic_string<char, std::

How can I switch to ruby 1.9.3 installed using Homebrew?

阅读更多关于 How can I switch to ruby 1.9.3 installed using Homebrew?

I have installed ruby 1.9.3 using hombrew brew install ruby But default 1.8.7 is still used. How can I switch osx to use 1.9.3 as default ruby? Matthew Rudy I suggest you take a look at rvm . You can then set it as default with rvm use 1.9.3 --default But if you are happy with your homebrew install. Then just change the precedence of directories in the PATH Here is my /etc/paths # homebrews should always take precedence /usr/local/bin # the default stack /usr/bin /bin /usr/sbin /sbin This is important generally for homebrew, else the system version of git, ruby, pg_admin,... will all be used

“M-” bindings in vim on iTerm2/Terminal don't work

阅读更多关于 “M-” bindings in vim on iTerm2/Terminal don't work

问题 I noticed that iTerm2 offers the very convenient feature of using "Option key as +ESC" (or as meta, but apparently that's obsolete). I tried them both and the option key works as expected in Bash ( set -o emacs mode) and Emacs, but not in Vim. Thus, I can't make use of any "M-" bindings. What I've found is that: if I set option to "+ESC", vim just understands ESC+key, and has no idea I actually meant Meta-key. if I set option to "meta", keys modified with "option" behave just as without a
