Qt Quick 2 Plugin Extension Sample

In this project, I created a qml plugin and got the output from it, and I plan to use it in another project.

Cmake is used in this library.

Usage

MyPlugin Project

To build an exportable plugin, the following are required.

CMakeLists.txt

set(PROJECT_NAME "MyPlugin")
set(QML_PLUGIN_DESTDIR "../Release/")

install(DIRECTORY "${CMAKE_BINARY_DIR}/${PROJECT_NAME}" DESTINATION ${QML_PLUGIN_DESTDIR}
        FILE_PERMISSIONS
            OWNER_READ OWNER_EXECUTE OWNER_WRITE
            GROUP_READ GROUP_EXECUTE
            WORLD_READ WORLD_EXECUTE
        DIRECTORY_PERMISSIONS
            OWNER_READ OWNER_EXECUTE OWNER_WRITE
            GROUP_READ GROUP_EXECUTE GROUP_WRITE
            WORLD_READ WORLD_EXECUTE
        FILES_MATCHING PATTERN "*")

MyPluginTest Project

To build an exportable plugin, the following are required.

CMakeLists.txt

set(MYPLUGIN_PATH "./MyPlugin")

qt_add_library(MyPlugin STATIC)
qt_add_qml_module(MyPlugin
    URI MyPlugin
    QML_FILES
        ${MYPLUGIN_PATH}/MyItemControls.qml
)

target_link_libraries(appMyPluginTest
    PRIVATE Qt6::Quick MyPluginplugin
)

NOTE: The following part can be ignored and not added to the project (Issue #1)

main.cpp

#include <QtQml/qqmlextensionplugin.h>

Q_IMPORT_QML_PLUGIN(MyPluginPlugin)

Usage

Step 1

After building the MyPlugin plugin, you must run the following command in that folder.

cmake --install ./

Note: That Cmake must be installed on your system before that.

Now you will have a folder called Release in the folder next to "MyPlugin", where the library outputs are placed.

Release Folder Structure

└── MyPlugin
    ├── MyPlugin.qmltypes
    ├── MyPlugin_qml_module_dir_map.qrc
    ├── MyPluginplugin.lib
    ├── MyRecControls.qml
    └── qmldir

Step 2

Now we add "MyPlugin" folder from inside "Release" folder to our example folder.
