QML QtProtobuf

QML bindings for QtGrpc.

QML bindings for QtGrpc.

QtProtobuf allows to use generated classes in QML. All types are registred automatically when QtProtobuf::qRegisterProtobufTypes() called. To make generated classes and QtProtobuf types visible in QML you need to import QtProtobuf QML plugin and your protobuf package

sample.proto:

syntax = "proto3";
package qtprotobuf.sample;
message SampleMessage {
    int32 sampleField = 1;
}

QML:

//Enable QtProtobuf types
import QtProtobuf 0.4 //Use recent QtProtobuf version
//Import types from sample.proto
import qtprotobuf.sample 1.0
 
Item {
...
    SampleMessage {
        sampleField: 10
    }
...
}

Static QtProtobuf with QML

For statically built QtProtobuf it's neccssary to link protobufquickplugin target manually: CMakeLists.txt:

...
if(QT_PROTOBUF_STATIC)
    target_link_libraries(${TARGET} PRIVATE QtProtobuf::protobufquickplugin)
endif()
...

To make QtProtobuf QML plugin visible in QML, call Q_PROTOBUF_IMPORT_QUICK_PLUGIN() macro:

int main(int argc, char *argv[]) {
    ...
    QtProtobuf::qRegisterProtobufTypes();
    Q_PROTOBUF_IMPORT_QUICK_PLUGIN()
    ...
}
