Add Qaterial to existing Qt-Project using universal styled custom controls

[MichaelHeiser]

Hey,

I want to use Qaterial as main UI components in my applications. The application currently relies on a Universal styled custom control set. I managed to build Qaterial for Qt 5.15 and I also can build my application against it. App launches, but app crashes after loading my main qml file. I built qaterial on local hard drive and want to include the lib in my qmake base project.

Here my project file:

# set path and name of lib
CONFIG(debug, debug|release) {
    QAT_BUILDTYPE = Debug
}
else {
    QAT_BUILDTYPE = Release
}

#CONFIG += staticlib

DEFINES += "QATERIAL_STATIC=1"

*msvc*{
    INCLUDEPATH += $$PWD/../../../../Qaterial/install/win/$${QAT_BUILDTYPE}/include
    LIBS += -L$$PWD/../../../../Qaterial/install/win/$${QAT_BUILDTYPE}/lib \
    -lQaterial \
    -lQaterialIcons \
    -lQaterialFonts \
    -lQaterialComponents \
    -lQOlm
    DEPENDPATH += $$PWD/../../../../Qaterial/install/win/$${QAT_BUILDTYPE}/lib
    QML_IMPORT_PATH += $$PWD/../../../../Qaterial/qml/Qaterial
}

Load main file, in main file i did not import Qaterial. m_qmlEngine.load(QUrl(QStringLiteral("qrc:/EuroSoftLiveViewQml_win.qml")));

Init qaterial:

    m_engine->addImportPath("qrc:///");
    qaterial::loadQmlResources();
    qaterial::registerQmlTypes();

Starting app:

qaterial.utils: Load Qaterial v1.4.6 qaterial.utils: Load font ":/Qaterial/Fonts/Lato/Lato-Regular.ttf" qaterial.utils: Load font ":/Qaterial/Fonts/Roboto/Roboto-Medium.ttf" qaterial.utils: Load font ":/Qaterial/Fonts/Roboto/Roboto-Regular.ttf" qaterial.utils: Load font ":/Qaterial/Fonts/RobotoMono/RobotoMono-Regular.ttf"

Crash of app:

I've been able to use locally built Qaterial with QaterialGallery and HelloWorldExample, these applications start fine. So my idea is that my config in qtquickcontrolsconfig2.conf could be the reason?

[Controls]
Style=Universal

[Material]
Primary=#03A9F4
Accent=#01579B

[Universal]
Accent=#0086E6

Can anyone help me?

Hello you should simply use cmake, I don't know qmake. I have no idea from where the crash might come.

[MichaelHeiser]

Hello same behaviour.

Here parts of my cmake. Luckily I'm currently working on moving my prject from qmake 2 cmake.

When i don' add import path "qrc:///" I get following error:

qaterial.utils: Load font ":/Qaterial/Fonts/Roboto/Roboto-Medium.ttf"
qaterial.utils: Load font ":/Qaterial/Fonts/Roboto/Roboto-Regular.ttf"
qaterial.utils: Load font ":/Qaterial/Fonts/RobotoMono/RobotoMono-Regular.ttf"

qrc:/Qaterial/ApplicationWindow.qml:45:3: Qaterial.DialogLoader is not a type
WARNING: No translated disclaimer found. Using english disclaimer instead.

My application makes heavy usage of quickcontrols, could it be that loading qaterial "overwrites" quickcontrols object?

Maybe here: https://github.com/OlivierLDff/Qaterial/blob/598a80f89777d79e80efe23bf5faada46218a703/src/Qaterial/Details/Utils.cpp#L139-L143

Thank you very much!! This did the trick!!

m_engine->addImportPath("qrc:///");
qaterial::loadQmlResources(false);
qaterial::registerQmlTypes();

With this init without setting the style my app starts up.
