Hello everyone,<br>
I try to load on signal, a rasterlayer to qgsmapcanvas. I try it like in<br>
the pycookbook:<br>
<br>
@QtCore.pyqtSlot()<br>
def loadRasterImage(self):<br>
print "slot works"<br>
fileName = QFileDialog.getOpenFileName(<u></u>None, "historical map",<br>
".", "Image Files (*.png *.jpg *.bmp *.tiff)")<br>
fileInfo = QFileInfo(fileName)<br>
baseName = fileInfo.baseName()<br>
rlayer = QgsRasterLayer(fileName, baseName)<br>
if not rlayer.isValid():<br>
print "Layer failed to load!"<br>
QgsMapLayerRegistry.instance()<u></u>.addMapLayer(rlayer)<br>
print rlayer.extent().yMinimum()<br>
self.canvasRaster.setExtent(<u></u>rlayer.extent())<br>
self.canvasRaster.setLayerSet( [ QgsMapCanvasLayer(rlayer) ] )<br>
<br>
self.canvasRaster is defined in the gui . I search for 8h but I dont<br>
find a solutionen, because there are no errors.<br>
<br>
It load the rasterlayer to the main program of qgis, but not in my<br>
qgsmapcanvas. it is still white.<br>
