c++ - Syntax for extracting pointer from container back() -


is acceptable syntax? looks messy tends make me think not elegant:

cdata.lastanimation=&(this->animations.back());

cdata.lastanimation pointer, since back() returns reference, not pointer, need address?

you might thinking, why not make cdata.lastanimation reference instead of pointer? because cdata pod struct , references cannot assigned, unlike pointers, can. (perhaps 1 of few examples of why pointer better in cases reference).

yes, work fine, though can (very seldom not) shortened this:

cdata.lastanimation = &animations.back();

that seems little bit better me @ least.

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...
