c++ - Buidling Qt5 & QtQuick 2 application with GNU Make -


i trying build basic qt5 application uses qtquick 2 ui-language , build using gnu makefile. means, don't want use javascript, load qml layout , specify signals , slots in c++. however, here questions:

  1. what's best way load qml layout , access its' elements?
  2. how build such application directly gnu make instead of using qmake generate makefile?

please find first attempts below:

qml/main.qml

import qtquick 2.5 import qtquick.controls 1.4 import qtquick.dialogs 1.2  rectangle {     width: 360     height: 360     text {         text: qstr("hello world")         anchors.centerin: parent     }      mousearea {         anchors.fill: parent         onclicked: {             qt.quit();         }     } }

src/main.cpp

#include <qapplication> #include <qqmlapplicationengine> #include <sqlite3.h>  int main(int argc, char* argv[]) {   qapplication app(argc, argv);    qqmlapplicationengine engine;   engine.load(qurl(qstringliteral("qrc:/main.qml")));    return app.exec(); }

makefile

cc          = /usr/bin/g++ moc         = moc-qt5 cflags      = -wall -pedantic -std=c++0x -d_reentrant \                             -dqt_no_debug -dqt_gui_lib -dqt_core_lib -dqt_shared target        = yarott incpath         = -i. -i/usr/include -i/usr/include/qt -i/usr/include/qt/qtgui \                             -i/usr/include/qt/qtcore -i/usr/lib/qt/mkspecs/linux-g++ ldflags     = -l/usr/lib -lsqlite3 -lqt5gui -lqt5core -lgl -lpthread srcpath         = ./src binpath         = ./bin  defines         = $(shell find $(srcpath) -type f -name '*.h') sources         = $(shell find $(srcpath) -type f -name '*.cpp') objects         := $(patsubst $(srcpath)/%.cpp, $(binpath)/%.o, $(sources)) moc_sources := $(patsubst $(srcpath)/%.cpp, $(srcpath)/moc_%.cpp, $(sources)) moc_objects := $(patsubst $(binpath)/%.o, $(binpath)/moc_%.o, $(objects))  sources += $(moc_sources) objects += $(moc_objects)  all: bin $(target)  $(target): $(objects)     $(cc) $(cflags) -o $(binpath)/$(target) $(objects) $(ldflags) $(incpath)  $(binpath)/%.o: $(srcpath)/%.cpp     @mkdir -p "$(@d)"     $(cc) $(cflags) -c $< -o $@  $(srcpath)/moc_%.cpp: $(srcpath)/%.h     $(moc) $(defines) $(incpath) $< -o $@  # generate cc h via qt's meta object compiler # $(srcpath)/%.moc.cc: $(srcpath)/%.h #   $(moc) $(incpath) $< -o $@  # create bin folder bin:     mkdir $(binpath)  # remove bin folder clean:     rm -r $(binpath)

i'm trying link specific pdf page msoutlook'10 or msword'10, #page=... anchor particularly useful , works fine elsewhere. unfortunately when click [ctr-k] in outlook or winword, links re-formatted assuming unc path. pdf file located on shared drive. using "file:" prefix links open pdf in adobe reader (outside of browser), , "http:" open inside browser. issue seem need open in browser "file:" prefix in order anchor work. know anchors work inside browser. outlook uses windows/explorer default program (based on file extension) seems open in adobe reader neglecting anchor. is aware of solution, link specific page or bookmark of shared-pdf ms outlook and/or winword link? common references: mailermailer.com/...anchor-tags-html-emails campaignmonitor.com/...anchor-links-in-email-newsletters/ stackoverflow.com/...anchor-in-pdf-document

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
