[Qgis-developer] Re: Draw a single point

[Germán Carrillo]

I guess this can help you:

*self.marker = QgsVertexMarker( self.canvas )
*
*self.marker.setCenter( QgsPoint( x, y ) ) *
*self.marker.setIconType( 1 ) *
*self.marker.setIconSize( 10 ) *
*self.marker.setColor( QColor( 255,0,0,255 ) ) *
*self.marker.setPenWidth ( 1 ) *

As you see, just define the marker with your canvas as parent and set the
properties.

Regards.

Germán
