Cant launch Qt Quick Controls application

Dmitriy

Hello. I downloaded Qt 5.4 and created Qt Quick application with Qt Quick Controls 1.3. I didn't change anything in code, just build it (as release). Then i copied .exe to another folder, add all .dll files i need and when i launched my program there were no any windows, just process in Task manager. However, i can launch program which uses QtQuick 1.1. How can i fix it? Thanks.

Aren't you missing the platforms folder?

Dmitriy

@imyrvold what do you mean? Anyway i think there is something wrong with .dll files, because application with Qt Quick 1.1 works.

Maybe you can try the Windows Deployment Tool http://doc.qt.io/qt-5/windows-deployment.html it looks like that could help you, you don't see a window because it can not find the QuickControls plugin

Dmitriy

@Iktwo thanks for reply. When i use windeployqt, i type there:
C:\Qt\5.4\mingw491_32\bin\windeployqt.exe --release C:\Users\Dima\Desktop\folder\qtquickcontrols13.exe

And i have an error: 32 bit, release executable [QML]
Unable to locate ICU icuin53.dll (but this file is in folder with program)

Dmitriy

Ok, i made Windows deployment tool work, but there is no window appears. Process in Task manager only :(

Hi @Dmitriy ,

Check two things:

Does it work if you run it from inside Qt Creator?
Are all the required files in the correct locations? (.dll, .qml, qmldir) See http://wiki.qt.io/Deploy_an_Application_on_Windows

Dmitriy

@JKSH yes, program works with Qt Creator and all files are in the correct location.

@Dmitriy said:

yes, program works with Qt Creator

Ok, that means some files are still missing from your deployment folder. Go to http://wiki.qt.io/Deploy_an_Application_on_Windows again and follow the instructions under the section "Initial deployment (Quick and dirty)" very very closely.

In the meantime, could you please tell us if:

Did you create any extra QML files?
Did you use any custom images?
Did you use any external libraries?

Dmitriy

Thanks a lot for help. When i copied all the .dll files and folder my program finally works :) Now it's time to throw out some garbage :)

@Dmitriy You're welcome :) Good luck!
