}

i got working! thing tried show dialog, or whatever, clicking on toolbar - else other stuff in actual window.

so changed id in toolbar ontriggered, item in window, in case webview id: owmap. old id 1 2 rows , commented out.

now works!

                // change coordinates                 action {                     id: coordinateaction                     objectname: "action2"                      iconsource: qt.resolvedurl("toolbaricon.png")                     text: i18n.tr("coordinates")                      ontriggered: {                         //popuputils.open(dialog, coordinateaction)                         popuputils.open(coodialog, owmap)                         console.debug('debug: change coordinates pressed')                     }                 }

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 -
