i not sure if understood question correctly, give try:

   component     {              id: userdialog              dialog               {                  property int sourcestate : 1                  id: dialogueuser                  title: i18n.tr("image")                  image                   {                      id: usersskin                      fillmode: image.preserveaspectfit                      source: 1 == sourcestate ? "oldurl" : "newurl"                      sourcesize.height: 1200                  }                   button                   {                      text: i18n.tr("close")                      color: "red"                      onclicked:                       {                         popuputils.close(dialogueuser)                         dialogueuser.sourcestate = 0                                                  }                  }               }     }

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...
