[Qgis-user] python appliction example

[Germán Carrillo]

Hi Jachym, you have to do next things in demo_app.py:

1. Line 11: Use qgis_prefix = "/usr" instead of "qgis_prefix =
os.getenv("QGISHOME")". I don't know why last mode doesn't work for me.
2. Line 14: You have __init_ instead of __init__. (Important! Your GUI
doesn't initialize)
3. Line 28: useQImageToRender doesn't exists, use useImageToRender.
4. Line 56: Use mActionPan.png instead of mActionZoomPan.png
5. Line 61: Use mActionZoomFullExtent.png instead of mActionZoomFull.png
6. Line 76 and 77: You have QgsMapToolPan but you want create Zoom Tool, so
replace it with QgsMapToolZoom.
7. Line 89: Replace zoomFullExtent with zoomToFullExtent.
8. Line 106: You have a sintaxis error there: Use addMapLayer, not
adMapLayer.
9. Be carefull, every single word in your code is important.
10. Read again 9.

Yes, I'm on vacations... :)

Germán.
