[Marble-devel] overview map not displaying correctly

[Konrad Enzensberger]

Hi,

hello marble does not call:
//marble QtMainWindow.cpp
// The config dialog has to read settings.
m_configDialog->readSettings();

without this, you will not meat the overview methode:
void OverviewMap::setSettings( QHash<QString,QVariant> settings )

which emits the signal :  emit settingsChanged( nameId() )

and because of this, this slot is not called:
void OverviewMap::updateSettings()

and because of this, the overview member  m_svgPaths
will be empty, and no image can be loaded in:

void OverviewMap::changeBackground( const QString& target )
{
    m_svgobj.load( m_svgPaths[target] );
}

this could be a workaround if you do not create a configDialog
like marble QtMainWindow does (quick and dirty).

void OverviewMap::changeBackground( const QString& target )
{
//enz - no config dialog used
if(!m_svgobj.load( m_svgPaths[target] ))
{
QString path;
path = MarbleDirs::path( "svg/worldmap.svg" );
m_svgPaths[m_planetID[2]] = path;
m_svgobj.load( m_svgPaths[target] );
m_posColor = QColor(255,255,255);
}

}

regards, konrad
