c++ - Nested namespace can't be found in spite of including header file -


i have 2 projects, 1 sample (which compiles without error) , looks (first few lines shown only):

working example

#include "cinder/app/app.h" #include "cinder/app/renderergl.h" #include "cinder/surface.h" #include "cinder/gl/gl.h" #include "cinder/gl/texture.h" #include "cinder/rand.h" #include "cinder/qtime/quicktimegl.h"  using namespace ci; using namespace ci::app; using namespace std;  class qtimeadvapp : public app {   public:     void preparesettings( settings *settings );     void setup();      void keydown( keyevent event );     void filedrop( filedropevent event );      void update();     void draw();      void addactivemovie( qtime::movieglref movie );     void loadmovieurl( const std::string &urlstring );     void loadmoviefile( const fs::path &path );  };

note line: void addactivemovie( qtime::movieglref movie );

the other project, needs make use of same library (quicktime opengl within libcinder), tries similar - 1 again extract:

use in project

#pragma once  #include "abstractcontent.h" #include "cinder/gl/texture.h" #include "cinder/tween.h" #include "abstracttransition.h" #include "cinder/qtime/quicktimegl.h"  namespace th {      class videocontent : public abstractcontent {     public:         videocontent();         ~videocontent();         virtual void setup();         void loadmovie(ci::url url);         void loadlocalmovie(ci::fs::path path);         void setpreloadedmovie(ci::qtime::movieglref movie);

this 1 throws compiler error: no member named 'qtime' in namespace 'cinder'

notice again virtually identical line: void setpreloadedmovie(ci::qtime::movieglref movie); in fact, can use full qualified name ci:qtime:movieglref in first example , compiles fine (as expected).

what on earth going on here? why "use in project" version throw compiler error: no member named 'qtime' in namespace 'cinder'?

just clarity, quicktimegl.h file in turn includes file declares namespace , type def:

namespace cinder { namespace qtime {  typedef std::shared_ptr<class moviegl>  movieglref;

am missing something? i'm pretty sure i'm including correct header file, before, , trying use qualified namespace still compiler doesn't find definition?

have tried referencing global namespace, ::ci::qtime rather ci::qtime? should not make difference, c++ compilers trip on these kind of things.

angular - Ionic slides - dynamically add slides before and after -

hi i'm using ngfor create set of 3 slides while starting in middle i'm guaranteed able slide left or right on start. when slide right can simple listen reachedend , push slide array i'm looping. but have problem adding slide beginning. if same above , use e.g. array.unshift() or spread add item beginning, view think it's on position 0 , snaps view new slide. the code below work animates slide change index 1. slide = [0,1,2] //example loop slidechanged(event) { if(this.slides.isbeginning()){ this.slide = [this.slide[0]-1, ...this.slide]; this.slides.update(); this.slides.slideto(1) } } <ion-slides [initialslide]="1" (ionslidedidchange)="slidechanged($event)"> <ion-slide *ngfor="let item of slide"> <h1>slide {{item}}</h1> </ion-slide> </ion-slides> any appreciated! you can using ionslidenextend , ionslideprevend events slides . please

minify - Minimizing css files -

i want know how css files can minimized. currently, using external sites css minifier compress css files. however, after removing whitespaces, comments, etc, file sizes reduced 10-15%. how frameworks bootstrap manage make minimized versions kilobytes. as example, css is: body { background-color: #ff0; } the reduction goes 28 bytes 22 bytes other css files have lot more characters still smaller this. actually minifying code means it's remove thing code white space characters new line characters comments block delimiters it reduces amount of code has transferred on web , speed site load fastly.but unreadable format.

Add a dynamic header in angular 2 http provider -

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom
