示例1: processAddingNodesOnPress
bool PolylineAnnotation::processAddingNodesOnPress( QMouseEvent *mouseEvent )
{
if ( mouseEvent->button() != Qt::LeftButton ) {
return false;
}
GeoDataLineString *line = static_cast<GeoDataLineString*>( placemark()->geometry() );
// If a virtual node has just been clicked, add it to the polyline and start 'adjusting'
// its position.
const int virtualIndex = virtualNodeContains( mouseEvent->pos() );
if ( virtualIndex != -1 && m_adjustedNode == -1 ) {
Q_ASSERT( m_virtualHoveredNode == virtualIndex );
line->insert( virtualIndex + 1, line->at( virtualIndex ).interpolate( line->at( virtualIndex + 1 ), 0.5 ) );
m_nodesList.insert( virtualIndex + 1, PolylineNode() );
m_adjustedNode = virtualIndex + 1;

// If a virtual node which has been previously clicked and selected to become a
// 'real node' is clicked one more time, it stops from being 'adjusted'.
