How can I use QQC1 module with Qt6?

devriang

Hello,
I hope to use Menu in QQC1.
According to the description, in QQC2, Menu is Item-based popup and I cannot popup a menu without restricting within window boundaries. (https://doc.qt.io/qt-5/qtquickcontrols2-differences.html)
Now I am using CMake to build a project, and just tried to load QQC1 but failed.
I've got an CMake Error like "The INTERFACE_QT_MAJOR_VERSION property of "Qt5::Core" does not agree with the value of QT_MAJOR_VERSION already determined for "project_name"."

Following is a part of my CMakeLists.txt contents.

find_package(Qt6
COMPONENTS
Core
Gui
Quick
Qml
QuickControls2
REQUIRED
)
find_package(Qt5
COMPONENTS
QuickControls
REQUIRED
)

Am I using it wrong..?
How could I resolve the error?
(I installed Qt5 with specifying Qt5_DIR and there seems to be no problem with finding Qt5 directory.)

Help me plz,
Thank you

Hi,

You can't mix and match two different major versions of Qt in the same application like that.

@SGaist Thank you for answering.
Should I understand that there's no way to use QQC1's Menu since it's removed from Qt6?

SGaist

That's correct.
