anyone please me, how load xml file in groupdatamodel located in above device directory location.

thanks in advance.

we have 2 parts :

first 1 allowing application use shared folders

steps:

1. go bar-descriptor.xml in project
2. select application
3. check true in shared files

second 1 correct path using c++ , send qml in context property

this in apllicationui.cpp c++ code

// build path, add context property, , expose // qml qstring workingdir = qdir::currentpath(); qstring path = "file://" + workingdir +"/shared/documents/model.xml"; qdeclarativepropertymap* dirpaths = new qdeclarativepropertymap; dirpaths->insert("documents", qvariant(qstring(path))); qml->setcontextproperty("dirpaths", dirpaths); 

qml

    datamodel: xmldatamodel {             source: dirpaths.documents     }
