Hi Stefan,
Your code really helps.
I can refresh a layer now.
What I did is to do all recurrent task in the run(TaskMonitor monitor,
PlugInContext context) function. Create a layer, and retrieve dataset from
database by creating a recordset _RS, then loop it using the following code
while (_RS.next()){
if(monitor.isCancelRequested()){return;}
updatePostgisLayer(Changing, _RS); // this update a specify attribute to
control color.
monitor.report(count, 100, "Evolution");
count++;
Thread.sleep(1000L); // delay a bit so that you can see the changes.
Changing.fireLayerChanged(LayerEventType.APPEARANCE_CHANGED); //refresh
}
BTW, in your code, I see that you are using
movieLayer.setFeatureCollectionModified(true);
and
movieLayer.setFeatureCollectionModified(false);
In what circumstance, you need to use it.
Many Thanks,
Elton
