java - Eclipse dialogs open twice when clicked with mouse -


within past 2 weeks, eclipse has started behaving oddly. not sure changed, although did install jdk , jre 7u21.

any dialog (search, eclipse about, switch workspace, etc.) open clicking menu item mouse opens twice. 1 dialog displays directly behind -- when you're done 1 , hit ok or close, there's waiting behind it. if drag first 1 side, other identical dialog right behind it.

sometimes fact 2 dialogs open disrupts contents or functionality of 1 or both of dialogs. example, file filters in search dialog might blank 1 of 2 popups, , neither of 2 search windows works.

the same dialogs, if opened keyboard shortcuts (click search menu, press f on keyboard open file search dialog), display 1 dialog. no functionality issues dialogs opened way.

no other program exhibits behavior.

why happening , how make stop?

i've searched google , found no clues.

here things i've tried:

  • i using eclipse 3.8 sr2. tried creating new workspace. same behavior in clean workspace.
  • i tried launching eclipse -clean option. startup took longer, no change in dialog behavior.
  • i unzipped old copy of eclipse 3.8 sr2 , tried clean copy of eclipse system. same behavior.
  • i downloaded , switched eclipse 4.2 sr2. started new workspace. same behavior.
  • i unplugged usb mouse , tried using laptop touchpad alone. same behavior.
  • i've checked workspace\.metadata\.log, there no related entries.

i had problem laptop , found out nview desktop manager. had turned on experimenting different settings. disabled nview, problem went away within eclipse juno.

i hope helps.

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...

c++ - qgraphicsview horizontal scrolling always has a vertical delta -

Image
i've subclassed qgraphicsview custom canvas used in cad application. i've reimplemented qgraphicsview::wheelevent check keyboard modifiers control key and, if control key pressed, zoom. i'm trying implement horizontal scroll when user holds shift , uses wheel. the problem i'm having horizontal scrolling always scrolls 0.279. not huge problem, hugely annoying , points else being wrong. so, here questions: is right way implement horizontal scrolling? if not, is? how eliminate delta of 0.279? thanks in advance. code , sample output below void myview::zoom(int delta) { double factor = pow(1.2, delta/abs(delta)); this->scale(factor, factor); } void myview::scrollhorizontal(int level) { qpointf center = maptoscene(viewport()->rect().center()); qdebug() << "center: " << center.x() << ", " << center.y(); centeron(qpointf(center.x() - level, center.y())); } void myview::wheelevent(qwheeleve...
