I've pushed a fix for this issue.
Please, confirm if it works now.
Cheers.

and you can use a simple dictionary:
fields = layer.pendingFields()
field_names = [field.name() for field in fields]
for elem in layer.getFeatures():
atr = dict(zip(field_names, elem.attributes()))
The result is a Python dictionary:
{u'DIP_DIR': 120, u'STRATI_TYP': 1, u'DIP':

Hi all
Qt already has an open gl based paint device ( QGLPixelBuffer ), so the
effect of hardware acceleration can be tested just by replacing the
QImage with a pixel buffer. I did this years ago and ( can't remember
the Qt version ), the rendering with QGLPixelBuffer was slower on my

Hello,
I inserted a new version of GEarthView plugin for QGis.
When possible, please test it for the approval
These are the updates:
- Added publishing in KML also vector elements inside the view (with
attributes)
- Added an info panel
Regards

You are the best: you solved in a second all my ploblems :)
Thank thank thank you.

Hey Roberto,
No need for all that :)
This is all you need:
rq = QgsFeatureRequest(iface.mapCanvas().extent())
for feature in layer.getFeatures(rq):

Hello all again,

So, I taken the canvas coordinates and I created a string that has the
"expression" syntax:
text = self.iface.mapCanvas().extent().toString()
text1 = t
There is also a more ambitious option, detach in QGIS the render of the objects
of the painting technology ( Currently Qt+QPainter ) using interfaces as Ogre,
Irrlicht or OSG does.
Then could be implemented several 2D/3D-CPU/GPU renderers ( Qt4-5, OpenGL,
OpenGL ES, Ogre, OSG ...) being the re

In web mapping contexts, major improvements are made in 2D vector rendering
speed by using WebGl technology, such as in upcoming OpenLayers 3. As a
