sorting - Preserve insert order of object array after sort in Javascript -


i've got array of objects following:

var = {  "typeid" : 15,  "attr1" : "something" };  var b = {  "typeid" : 17,  "attr1" : "something" };  var c = {  "typeid" : 15,  "attr1" : "something" };  var d = {  "typeid" : 15,  "attr1" : "something" };  var e = {  "typeid" : 1,  "attr1" : "something" };  var objectarray = new array(); objectarray.push(a); objectarray.push(b); objectarray.push(c); objectarray.push(d);

i tried sort array using typeid value order, need preserve order insert. meant, final order must following:

e,a,c,d,b

but when implement classical sort algorithms(bubble or quicksort) array ordered insert order of similiar value(typeid) in different possition.

i tried order @ first time similar types of objects, got lost rest.

if you're asking how implement sort function preserves initial order of objects have identical sort keys, ways know of are:

  1. use sort algorithm guaranteed preserve original order ties

  2. add secondary key original sort ordinal , use sort algorithm looks @ secondary sort key ties.

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...
