php - Else If block and curly brackets -


knowing in php ignore curly brackets in conditional blocks 1 function / line after "if", "else if" or "else" tag, : 

if (myval == "1")   dothis(); else if (myval == "2")   dothat(); else   donothing();

i asking myself if :

 if (myval == "1")   dothis(); else    if (myval2 == true)     dothat();   else     donothing();

was seen php either : 

if (myval == "1") { dothis(); } else  {   if (myval2 == true)     { dothat(); }   else      { donothing(); } }

or : 

if (myval == "1")   { dothis(); } else if(myval2 == true)   { dothat(); } else    { donothing(); }

short version : "line break" after 1 else enough separate 1 "if" statement or seen 1 "else if"

editing own question confirmation guess : 

if(false)   echo "1"; else    if (false)     echo "2"; else   echo "3";

is displaying "3" while following throwing error because 2 else statement found :

if(false)   echo "1"; else    if (false)     echo "2";   else     echo "4"; else   echo "3";

so break line doesn't seems make difference, thing matters "if" , "else" count.

without curly brackets php treat next line block of code execute.

if (myval == "1")     dothis(); else      if (myval2 == true)     dothat();     else     donothing();

if myval "1" dothis(); next line , picked block of code execute. if there more code there:

if (myval == "1")     dothis();     dothistoo();

it still execute dothis() part of if statement, whilst dothistoo() always executed.

if myval != "1" picks first block in else condition , executes that. in case if statement needs evaluated:

if (myval2 == true)

this logic continues: identify next block of code execute either taking next line or next block identified wrapping of curly braces.

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...
