| [jdt-ui-dev] Location in editor problems when source is folded |
Hope this isn't to tediuos a question, here goes:
I have made a plugin that displays some information on top of a method int he editor when I get an event.
The following code works fine when nothing is folding in the editor, but if I fold a long list of import statements the location returned by this code is off by quite a bit, and in some cases I get an "Index out of bounds" from StyledText.getLocationAtOffset(int offset).
Snippet:
if (mElement instanceof IMethod) {
IMethod method = (IMethod) mElement;
Point methodP = new Point(0, 0);
try {
int offset = method.getSourceRange().getOffset();
int methodOffset = method.getNameRange().getOffset();
Point p = mSt.getLocationAtOffset(offset);
methodP = mSt.getLocationAtOffset(methodOffset);
methodP.x = p.x;
methodP.y -= getTag().getBounds().height;
getTag().setLocation(methodP);
} catch (JavaModelException e) {
log.error(ACView.getPrefix() + "Error setting position", e);
}
}
Info:
mElement is of type IJavaElement
and I have checked for:
mElement.getElementType() == IJavaElement.METHOD
mSt is off type StyledText.
Im a bit unsure of how Im supposed to handle folding in the editor, or am I doing something totally wrong?
Any help is much appreciated on how I always retrieve the correct possition of the element.
