What do you mean, with the symbology. In front of the layer, in the
legend, is a raster icon, if you mean this.
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.
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.
It's confusing me.

Hello everyone,
I try to load on signal, a rasterlayer to qgsmapcanvas.
I try it like in
the pycookbook:
@QtCore.pyqtSlot()
def loadRasterImage(self):
print "slot works"
fileName = QFileDialog.getOpenFileName(None,
"historical map",
".", "Image Files (*.png *.jpg *.bmp *.tiff)")
fileInfo = QFileInfo(fileName)
baseName = fileInfo.baseName()
rlayer = QgsRasterLayer(fileName, baseName)
if not rlayer.isValid():
print "Layer failed to load!"
QgsMapLayerRegistry.instance().addMapLayer(rlayer)
print rlayer.extent().yMinimum()
self.canvasRaster.setExtent(rlayer.extent())
self.canvasRaster.setLayerSet( [
QgsMapCanvasLayer(rlayer) ] )
self.canvasRaster is defined in the gui . I search for
8h but I dont
find a solutionen, because there are no errors.
It load the rasterlayer to the main program of qgis, but
not in my
qgsmapcanvas. it is still white.
Is the layer loaded, showing in the legend but just not visible?
Check the symbology for the layer is defined properly if this is the
case.
Regards
Tim
please help me.
