Hello,
as it should be clear for all, I am not a java guru... sorry if this is
boring...
But looking at jMapPane code there is a problem since gt273 for my use case.
I have a JMapPane in a swing interface, something like:
private org.geotools.swing.JMapPane jMapPane_1;
jMapPane_1 = new org.geotools.swing.JMapPane();
jMapPane_1.setRenderer(new StreamingRenderer());
[... creating mapcontext here....]
jMapPane_1.setMapContext(myMapC); // throw error here...
Looking at jMapPane code:
setTransforms(final Envelope envelope, final Rectangle paintArea) is called
with a null paintarea rectangle from doSetDisplayArea method and giving, as
expected, a NPE at paintArea.getWidth().
In fact, the currentPaintArea variable is never setted.
The only function able to set it is setForNewSize() called by events
(HierarchyListener and HierarchyBoundsListener).
I can fix this, calling, for example, setForNewSize()
in doSetMapContext(MapContext context) like this:
setFullExtent();
setForNewSize(); // added
doSetDisplayArea(fullExtent);
This is probably not a fix but just to understand, just hopping to help.
I have others strange behavior with my mappane... for now, I will stay with
gt 272 and keep my application running fine.
thx.
