Hi,
I am new to Marble and Qt.
I wrote this short code to test the possibility to use Marble for Ham
Radio applications. I tried it with this KML File:
http://web.bxhome.org/sites/default/files/usr/pfx.kmz to display so
called DXCC entities.
#include <QtGui/QApplication>
#include <QtCore/QFileInfo>
#include <QtCore/QDebug>
#include <marble/MarbleWidget.h>
#include <marble/GeoDataDocument.h>
#include <marble/GeoDataTreeModel.h>
#include <marble/MarbleModel.h>
using namespace Marble;
int main(int argc, char** argv)
{
QApplication app(argc,argv);
MarbleWidget *mapWidget = new MarbleWidget();
mapWidget->model()->addGeoDataFile("/home/tom/projects/Qt/dxcc/test.kml");
mapWidget->resize(800,600);
mapWidget->setWindowTitle("DXCC Map");
mapWidget->setMapThemeId("earth/bluemarble/bluemarble.dgml");
mapWidget->setZoom(1100);
GeoDataCoordinates
position(8.545486,53.106076,0.0,GeoDataCoordinates::Degree);
mapWidget->centerOn(position);
mapWidget->show();
return app.exec();
}
When I start this program, the position and zoom level is correct, but
only for a short moment, less than a second.
Then the globe will be shrinked for roundabout the half size of the
window and the center position goes to 30° longitude and 15° latitude. I
think this happens, if the KML file is complete loaded.
This doesn't happen, if I reduce the KML file to one entity. With two
entities the zoom level goes up, but also the position is set to 30°
longitude and 15° latitude.
This is not, what I want. I try to display a specific DXCC entitiy
centered and zoomed. Where is my mistake?
Thanks,
Tom
