I am in the process of learning both QtSql and QML, so there is some room for errors.
Pretty much my whole problem is in the title of my question.
I tried to make a short, self-contained code to reproduce it :
C++ code :
int main(int argc, char *argv[])
{
QGuiApplication app(argc, argv);
QtQuick2ApplicationViewer viewer;
// uncomment after first launch, deleted test to make code short
// QFile::remove("my.db.sqlite");
QSqlDatabase db = QSqlDatabase::addDatabase("QSQLITE");
db.setDatabaseName("my.db.sqlite");
db.open();
QSqlQuery create("create table List (sample_text char(200))");
QSqlQuery create2("insert into List values (\"message !\")");
create.exec();
create2.exec();
QSqlQueryModel *someSqlModel = new QSqlQueryModel();
someSqlModel->setQuery("SELECT * FROM List");
QQmlContext *context = viewer.rootContext();
context->setContextProperty("datamodel", someSqlModel);
viewer.setMainQmlFile(QStringLiteral("qml/test/main.qml"));
viewer.showExpanded();
return app.exec();
}
QML Code :
Rectangle {
ListView {
width: 200; height: 200
model: datamodel
delegate: Row {
Rectangle {
width: 100; height: 40
Text {
anchors.fill: parent
text: display
}
}
}
}
}
I should get “message !” as output in my list, but I get :
message !
message !
Any help ? Thanks!
