Hi,
How to pass data to qt geoservices plugin backend in C++ and QML?

@Alien What do you mean by "passing data"? Which data do you want to pass to the plugin?

@Schluchti
Sorry I have to explain more.
For instance imagine you want to set visibility a layer in your geographic app so you have to send some information to geo plugin backend to make it aware of this change or sometimes you want to add a new layer of map to the showing map dynamically so how can I raise some signal or events or ... to geoservices plugin in qt(how to interact with)?

Also I use Qt 5.9
