i saw c++11 code fragment in this boostcon presentation jeremy siek : deque<int> topo_order; topological_sort(g, front_inserter(topo_order)); (int v : topo_order){ //line 39 cout << tasks[v] << endl; } upon trying compile in gcc there following error: main.cpp:39: error: expected initializer before ‘:’ token which got me wondering, compilers support syntax? well, @ least gcc supports in 4.6 (feature called "range-based for"). if have latest version, don't forget add -std=c++0x option.

i'm looking way use image window, or, @ least, in appearance. logical solution seems using invisible window visible components. google offers me 2 solutions : awful 1 : take screenshot of under window , use background while making window undecorated. "on way official" 1 : use awtutilities make window transparent. cool, doesn't work icedtea or linux (i didn't try official jre on linux yet). is there other way achieve same result (using awt or swing) ? unfortunately quick answer window transparency @ least no (unless wants prove me wrong, love!) screenshots may work better think though if contents of window aren't changing much. the awtutilities method (or same thing in official api java 7 onwards) requires hardware acceleration prohibits working 100% reliably across platforms, it's not guaranteed work on windows boxes.
