I can not read local file from qrc in qt5.11.2 + MSVC2017

Michael Rozshko

Hello I used Qt 5.11.2 with MSVC2017 (only for qwebengine support). I want to load some qrc, but have error (device cannot open). And watch that file url changefrom ":/files/pagespeed.html" to windows ":\files\pagespeed.html" :c So maybe I get error from thic changes. How I can disable auto replace separator fo qrc or how I can read file from qrc? I clean all and rebuild project, but it not help me.

I use some code:

    QFile f(":/files/pagespeed.html");
    f.open(QIODevice::ReadOnly);
    QString html = QString(f.readAll());
    f.close();

Qrc file

<RCC>
    <qresource prefix="/files">
        <file>pagespeed.html</file>
    </qresource>
</RCC>

pro file

QT       += core gui

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets webengine webenginewidgets

TARGET = qt5-web
TEMPLATE = app

DEFINES += QT_DEPRECATED_WARNINGS

CONFIG += c++11

SOURCES += \
        main.cpp \
        mainwindow.cpp

HEADERS += \
        mainwindow.h

FORMS += \
        mainwindow.ui

RESOURCES += \
    main.qrc

My error

Thanks!

hi @Michael-Rozshko

qt manages the path seperator for you (internally) if you sty with the non Windows variant :)

Anyway, did you rerun qmake after adding the file to your Qt-Ressource file ? otherwise the file will not be packed into the binary file.

Also you can try it with the url version of the path:

"qrc:/files/pagespeed.html"

You are right! It is my error, rebuild all project with full delete old directory and all work fine. Thanks for fast and good answer!
