Alexandre
I wanted to give an update on this.
Use case 1:
- Store a reference to the feature in the data portion of a QWidget
- On a callback, make the layer editable and pass the stored feature to
the openFeatureForm
This works and enabled the feature to be edited. HOWEVER, the feature may
already have been changed so could be in a stale state.
Use case 2:
- On the same call back, look up the new feature using
layer.getFeatures()
- Make the layer editable and pass the "returned" feature to the
openFeatureForm
This fails. Feature form opens as non editable.
Use case 3:
- Use the original feature.
- Copy the attributes from layer.getFeatures() to ensure the old
feature is in sync.
- Make the layer editable and pass the "updated" feature to the
openFeatureForm
This appears to work ok. See issue raised here:
https://hub.qgis.org/issues/11395
Telemetry Layer has been updated to support the working scenario:
