i have installed components of google's plugin eclipse button allows create visual classes not respond when click on it. the version of gwt designer included in gpe slimmed down version not include things creating ui classes eclipse menus. if want functionality, need install full gwt designer here: http://dl.google.com/eclipse/inst/d2gwt/latest/4.3 note did verify still allows opening desired ui class creation wizards, have not verified works gwt 2.6. think should work in gwt 2.6.1 cannot guarantee that. i've used gwt 2.5.1. note original title referred swing designer. swing designer has never been part of google plugin eclipse. google donated product open-source community , maintained eclipse. bundled versions of eclipse part of windowbuilder. forum here: https://www.eclipse.org/forums/index.php/f/214/ you can swing designer eclipse 4.3 update site: kepler - http://download.eclipse.org/releases/kepler

is there way add subdirectory of remote repository subdirectory of repository git-subtree? suppose have main repository: / dir1 dir2 and library repository: / libdir some-file some-file-to-be-ignored i want import library /libdir main /dir1 looks this: / dir1 some-file dir2 using git-subtree, can specify import dir1 --prefix argument, can specify take contents of specific directory in subtree? the reason using git-subtree can later synchronize 2 repositories. i've been experimenting this, , found partial solutions, though none quite perfect. for these examples, i'll consider merging 4 files contrib/completion/ of https://github.com/git/git.git third_party/git_completion/ of local repository. 1. git diff | git apply this best way i've found. tested one-way merging; haven't tried sending changes upstream repository. # first time: $ git remote add -f -t master --no-tags gitgit https://githu...
