TreeView in Qt5?

[Creaperdown]

@J-Hilk Hey, thanks for the link! I think I came across this once but had severe problems getting it to build with CMake. Is it compatible with CMake, or am I forced into using qmkae with it?

[J.Hilk]

@Creaperdown the git repo has a cmakelist and a pro file, sp both ?

Im not sure, haven't used it myself yet

[Creaperdown]

@J-Hilk It does, but in the README.md it says:
"NOTE: If you use Qt 6, you can also build with cmake. But if you're using a Qt version
below Qt 6.2, you need to do "git checkout 6.1" before building."

Might there be a way around this? How would I be able to use this in my Cmake project? Or if I cant build it with cmake, can I at least somehow use a qmake sub-project in my cmake project?

[J.Hilk]

@Creaperdown someone else might be able to help you here more, sry

AFAIK you can not simply mix cmake and qmake, in your project

What I see is that if you translate this pro file to a cmake file, you should be able to use it?

@J-Hilk I have no experience with qmake, how would I translate this to cmake? Is there a command I need to run on it or should I manually do it?

In Qt 6, Qt modules are built with CMake. In Qt 5, they are built with qmake.

Use qmake to build and install it into your Qt folder (qmake && make && make install). After this, you should be able to use it in your CMake project.

@JKSH My cmake Project is an open source application hosted on github, I cant just compile it and use the local copy. I'd need a solution which integrates with my build process

I see. I'm afraid I don't have the knowledge to help you with direct CMake integration.

@JKSH Thanks for trying anyways. Do you have an idea on how I could proceed from here? I cant seem to find a solution to this and so far I reaching out for help didn't work out. Is my best option to just wait?

You're welcome.

You could try posting a feature request at https://bugreports.qt.io/ and see if The Qt Company would provide CMake build files for Qt 5.

Alternatively, would it be feasible for you to build the module, host the built artifacts in a public place (say, https://cloudsmith.com/ -- they have a generous free tier for open-source projects) and use those in your build process?

[Creaperdown]

@JKSH I'll submit the feature request, but I suppose this could take quiet a long time to be added, if it will added in the first place.

The way of pre-building it and fetching the binaries from a cloud seems very cumbersome and fragile, I'd prefer not to use this if possible.

Wouldn't it be a better option to fall back on a non-official TreeView (e.g. something like this: https://github.com/ColinDuquesnoy/QtQuickControls2.TreeView) at this point?

I managed to do it by using add_custom_target to invoke qmake from my cmake file.
My cmake file now looks like this:

cmake_minimum_required(VERSION 3.20)
project(TreeViewTest VERSION 1.0
                     LANGUAGES CXX)


# Configuration
set(TREE_VIEW_OUTPUT ${PROJECT_BINARY_DIR}/qt_tree_view/qml/QtQuick/TreeView)
set(QML_IMPORT_PATH ${TREE_VIEW_OUTPUT} CACHE STRING "Qml modules")


# Qt
set(CMAKE_AUTOUIC ON)
set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTORCC ON)



# Dependencies
find_package(QT NAMES Qt5 COMPONENTS Quick Widgets QuickControls2 REQUIRED)
find_package(Qt${QT_VERSION_MAJOR} COMPONENTS Quick Widgets QuickControls2 REQUIRED)


# Build
add_executable(appTreeViewTest
    src/sources.qrc
    src/main.cpp
)



# Add treeview
add_custom_target(qt_treeview_qmake ALL
    BYPRODUCTS ${TREE_VIEW_OUTPUT}/libqquicktreeviewplugin.so
    COMMAND mkdir -p qt_tree_view
    COMMAND qmake -o qt_tree_view ${PROJECT_SOURCE_DIR}/libs/qttreeview
    COMMAND make -C ${PROJECT_BINARY_DIR}/qt_tree_view
    VERBATIM
    USES_TERMINAL
)


# Make treeViewTest depend on qt_treeview_qmake
add_dependencies(appTreeViewTest qt_treeview_qmake)
message(${PROJECT_BINARY_DIR}/qml/QtQuick/TreeView)


# Link
target_link_libraries(appTreeViewTest
    PRIVATE
        Qt5::Quick
        Qt5::Widgets
        Qt5::QuickControls2
        ${TREE_VIEW_OUTPUT}/libqquicktreeviewplugin.so
)

It surely can be improved, but this is the raw fix I came up with.
