in converting swing fx have number of screens have bunch of fields along long text description letting user know routine does. we not know width of screen before laid out, makes difficult call setwrappingwidth on text node. without calling setwrappingwidth, seems text node determines size of scene (assuming long description , wouldn't wrap without setwrappingwidth being called). currently have scene inside jfxpanel inside jinternalframe. typically call pack() method once setscene called on jfxpanel have screen size itself. i hoping exclude text node scene's width calculations , set wrapping width once scene sized. suggestions how handle this? thanks

is possible setup trigger git or github s.t. i'm notified if subfolder of git repo updated? or better, possible setup trigger s.t. i'm notified if pull request involves subfolder of git repo? you use github webhooks to: send payload integration service (ifttt, zapier, elasti.io, etc.) filter/search payload condition seeking notify via preferred method :) without github, accomplish using scripting language of choice via git hooks . unfortunately, github not support git hooks, other git hosting services do.

now we've reached swift 2.0, i've decided convert my, yet unfinished, os x app swift. making progress i've run issues using termios , use clarification , advice. the termios struct treated struct in swift, no surprise there, surprising array of control characters in struct tuple. expecting array. might imagine took me while figure out. working in playground if do: var settings:termios = termios() print(settings) then correct details printed struct. in obj-c set control characters use, say, cfmakeraw(&settings); settings.c_cc[vmin] = 1; where vmin #define equal 16 in termios.h. in swift have do cfmakeraw(&settings) settings.c_cc.16 = 1 which works, bit more opaque. prefer use along lines of settings.c_cc.vim = 1 instead, can't seem find documentation describing swift "version" of termios. know if tuple has pre-assigned names it's elements, or if not, there way assign names after fact? should create own tuple named elements ,

"a little more information. c++ exceptions and, under modern abi, objective-c exceptions extremely cheap set (@try), expensive @throw , @catch. when @throw happens, there heavy cost generating bits necessary unwind stack. unfortunately, appkit has issue causes unwind info generated normal part of operation (without throwing exception). thus, appkit operations in 64 bit can quite slow @ time. b.bum" http://www.cocoabuilder.com/archive/cocoa/217947-cocoa-application-running-very-slow-under-64-bit.html
