Hi,
I'm struggling with the Hoover support for folded regions.
Ive set my fProjectionSupport as shown in the docs:
8<==============================================
public void createPartControl(Composite parent) {
super.createPartControl(parent);
ProjectionViewer projectionViewer= (ProjectionViewer) getSourceViewer();
fProjectionSupport= new ProjectionSupport(projectionViewer,
getAnnotationAccess(), getSharedColors());
fProjectionSupport.setHoverControlCreator(new
IInformationControlCreator() {
public IInformationControl createInformationControl(Shell shell) {
return new DefaultInformationControl(shell);
}
});
fProjectionSupport.install();
projectionViewer.doOperation(ProjectionViewer.TOGGLE);
annotationModel = ProjectionViewer.getProjectionAnnotationModel();
}
===============================================>8
The folding itself works, but the hoover text showing the "folded" area
does not show up.
It should come if the mouse stays over a collapsed folding icon, correct?
Second question: is it possible to change the "-" and "+" icons for
folding?
Thanks a lot!
Best regards,
Wolf

Yes the hover should appear. I suggest to start debugging into
ProjectionAnnotationHover.getHoverInfo(ISourceViewer, ILineRange, int)

Yes, simply create your own projection annotations by subclassing
ProjectionAnnotation and overwrite paint(...).
