Hello all,
I'm wondering how one /should/ go about getting the position of a
character (e.g., in a TextNode). Currently, I'm trying to use the
BridgeContext to get a Bridge for the node, then using
TextBridge.getStartPositionOfChar(int) to get its location. If I do that,
though, I get a NullPointerException somewhere deep within the guts of
Batik:
public void updateCaret()
{
SVGTextElementBridge textBridge = (SVGTextElementBridge)
bridgeContext.getBridge(bridgeContext.getElement(caretMark.getTextNode()));
// Rectangle2D charBounds = textBridge.getExtentOfChar(caretPosition);
Point2D charStart = textBridge.getStartPositionOfChar(caretPosition);
caretOverlay.setShape(new Line2D.Double(0, 0, charStart.getX(),
charStart.getY()));
svgEditor.repaint();
}
results in:
java.lang.NullPointerException

(using Batik-1.5.1rc2; but the same thing happens with Batik-1.5).
Thank you for any and all help. It is appreciated.
