Hi list! QgsRubberBand items sometimes not refreshing properly when another map canvas item (QgsVertexMarker) intersects them. This happens with 2.8, in 2.6.1 works as expected.
See: https://www.dropbox.com/s/4egl61juue9ewop/rubberband.png?dl=0 as illustration How to reproduce: 1. Open empty project (epsg:4326) 2. Execute this script in python console: from PyQt4.QtCore import * from PyQt4.QtGui import * from qgis.gui import * from qgis.core import * mCursor = QgsVertexMarker(iface.mapCanvas()) mCursor.setIconType(QgsVertexMarker.ICON_BOX) mCursor.setIconSize(20) mCursor.setZValue(5) points = [[QgsPoint(0, 0), QgsPoint(20, 30), QgsPoint(0, 60)]] rb = QgsRubberBand(iface.mapCanvas(), True) rb.setToGeometry(QgsGeometry.fromPolygon(points), None) rb.setColor(QColor(125, 125, 0)) rb.show() def changeCursorPos(p): mCursor.setCenter(p) iface.mapCanvas().xyCoordinates.connect(changeCursorPos) 3. Move mouse cursor over rubber band. You can erase rubber band from bottom to some upper point. Tested on win7 32bit Anyone confirms? _______________________________________________ Qgis-developer mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/qgis-developer
