Do you have any labels with buffers using the old labeling tab?

Have you looked at qgisworkshop.org/html/workshop/plugins_tutorial.html? It is a tutorial about building a Qgis plugin.

Ragi, I am no longer scanning thru all features and I have finished the first version. plugins.qgis.org/plugins/flowTrace

I wrote a plugin that picks all features upstream of a selected line. I am finished with the first version. The only issue I was having was the length of time to iterate thru all features, which after reading Simplexio I realized I could greatly improve the iteration by using a spatial selection. The plugin will be called Flow Trace and will hopefully be available in the Qgis Plugin repository.

You just gave an idea. Instead of iterating through all features each time, I could set a selection buffer around my upstream point and only iterate thru those features. Thanks!

comment What is the fastest way to iterate through a list of features?
The plugin searches all features connected to a selected line. It does this by comparing upstream coordinate to downstream coordinate. If the distance between the coordinates is less than a tolerance than it will add the feature to a list and repeat the search for the newly selected feature. So I can't have a fixed rectangle but...

comment How to save label scales?
I have a polygon shapefile which represents parcels. I am labeling the polygons with an attribute containing the parcel ID and I only want the label to show up at scales less than 1:5000 so I set the max scale factor to be 5000. I zoom in and out to check my settings are correct. I save and exit. I open the file again and the scale factors are not set and the labels show up at all scales.
