The layer is loading in the legend and shown in the main window. <br>
What do you mean, with the symbology. In front of the layer, in
the legend, is a raster icon, if you mean this.<br>
<br>
I copied the code from the slot to the building of the ui. so the
layer is loading in the canvas by building the gui and not by
clicking in the toolbar. <br>
<br>
If I start qgis with this state of code, its starts and load load
the layer, when I start the plugin the canvas is still white and
when I clicked on the starting picture of qgis which is still
there, the layer is shown in the canvas of the plugin. <br>
<br>
It's confusing me.<br>

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(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().addMapLayer(rlayer)<br>
print rlayer.extent().yMinimum()<br>
self.canvasRaster.setExtent(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>
<br>

<div>Is the layer loaded, showing in the legend but just

defined properly if this is the case.</div>
