Hi and welcome to devnet forum

Similar as to your previous question you need to give more information about your actual problem.
What compiler are you using?
Also it would help to provide source causing the problem.

@koahnig
I use MinGw32_bits

after creating the Quick project everything goes well I compile perfectly but when I enter the designer for the design I receive an error in line 1 of the .qml file suddenly.
error: Qt Quick emulation layer crashed:( Line :1)

@Lelouche

Which of the default projects are using?

I have created the stack qt quick project and I can open the designer with the qml.

Which version of Qt creator are you using?

Lelouche

@koahnig
I use Qt 5.14.1

@Lelouche

Are you using Qt creator as development environment?

Lelouche

@koahnig
I use QT Creator as a development environment. I installed the open source version ..
sorry if i take a long time to answer just that i am new in the forum and i should only answer after every 10 minutes

Best is to create a new Qt Quick project. Compile and run as is to verify that it is properly created. Then try to use the designer on its .qml files. As indicated above, I have tried the application Stack

It should work with this project.
If not, you probably have a problem with your installation of Qt. Remove and reinstall the open source version completely.

Hello since I read your message I try in wine to solve the problem but nothing. I use the emulation layer given by Qt nothing works I even use the puppet nothing always but in revenge I noticed that my path was empty in the .pro file. should i add some path? I am waiting for your response thank you

QML_Import parth and QML Designer import parth are empty

@Lelouche

This is my automatically generated .pro file

QT += quick

CONFIG += c++11

# The following define makes your compiler emit warnings if you use
# any Qt feature that has been marked deprecated (the exact warnings
# depend on your compiler). Refer to the documentation for the
# deprecated API to know how to port your code away from it.
DEFINES += QT_DEPRECATED_WARNINGS

# You can also make your code fail to compile if it uses deprecated APIs.
# In order to do so, uncomment the following line.
# You can also select to disable deprecated APIs only up to a certain version of Qt.
#DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000    # disables all the APIs deprecated before Qt 6.0.0

SOURCES += \
        main.cpp

RESOURCES += qml.qrc

# Additional import path used to resolve QML modules in Qt Creator's code model
QML_IMPORT_PATH =

# Additional import path used to resolve QML modules just for Qt Quick Designer
QML_DESIGNER_IMPORT_PATH =

# Default rules for deployment.
qnx: target.path = /tmp/$${TARGET}/bin
else: unix:!android: target.path = /opt/$${TARGET}/bin
!isEmpty(target.path): INSTALLS += target

Both settings are empty as well.

This above are my Qt creator settings for Qt Quick.

At the moment I have no further idea of might be wrong with your setup.

Hi you are doing well I hope it is exactly the same as at home but I do not understand why mine has problems .. you use the open source version?

koahnig

@Lelouche

Yes, Qt5.14.1 open source for MinGW 32bit in this case.

Lelouche

@koahnig
Exactly the same thing as me but I do not know where there is the problem I will uninstall delete all related data and reinstall again. I'll let you know after that thank you

Lelouche

@koahnig
Hello to everybody . I'm fine, I hope .I tried to do what you asked me to uninstall and reinstall but I still don't get a positive result. the problem can come from where please? then that I also use there towards Open Source and Mingw32 bits.

Hi and welcome to devnet forum

Did you check already with a freshly through qt creator generated qml application?

Maurice

Hey koahnig,

thanks.

I have been working with Qt 5.9.0 for a while but I've never really used the Designer in QtCreator.
I wanted to try the Designer in 5.9 but that didn't work, with the same.
So Yesterday I installed a completely fresh new Qt 5.14.1 with the online installer and I tried the "heartrate-game" and the "gallery" example but this didn't work either with. I compiled with msvc2015 64 bit and i can also start the example, but the designer doesn't work..

I already tried with some other paths that i found as solution but nothing really fixed the problem.

Thanks for you help.
