Passing Paramater from .cpp file to .qml file

[chronoske]

Hello everyone...
I wanna asking you about passing parameter in .qml file from .cpp file.
I've a function for getting filename in widgetmap . . .
and then I would like to show map using .qml file.

@...
WidgetMap::WidgetMap(QString idofinformation, QWidget *parent) :
QWidget(parent),
ui(new Ui::WidgetMap)
{
ui->setupUi(this);

....
    //I get the filename from database
    //set the filename
    this->filename = this->hasil.result->__ptr[0]->FileName;
    //set the serverfilename
    ftpdownloader->serverfilename = this->filename;
    ...

}

WidgetMap::~WidgetMap()
{
delete ui;
}

//back toolbutton
void WidgetMap::slotToolButtonBack()
{
...
}

void WidgetMap::slotShowMap(bool failed)
{
// I use qml file by setting the source (detailMap.qml)

...
 this->view->setSource(QUrl(QString::fromUtf8(this->applicationdirpath.absolutePath().toUtf8() + "/DetailMap.qml")));
   ...

}@

and then this is in .qml file :
@
....

Rectangle
{
width: 640
height: 480

// Create a flickable to view a large image.
Flickable
{
   ...

   //I use
    Image
    {
        id: picture
        source: "denah.png"
        asynchronous: true
    }

    ...

}
@

I use filename to get it from database, then I want to set the filename in .qml file to show it using qml. How can I passing the filename in .qml file?
