Hi Fred,
the newest sources of ImageJ are on github; this is where I usually look
up things.
https://github.com/imagej/ImageJ/commits/master/ij/plugin/frame/RoiManager.java
The history says:
2024.09.10 (1.54k21; RoiManager.delete)

Greetings Michael,
Has this delete method been recently added? As of this posting I do not
find it:
google: imagej java RoiManager
...
https://imagej.net/ij/developer/api/ij/ij/plugin/frame/RoiManager.html
google: imagej java RoiManager java2html
...
https://imagej.net/ij/developer/source/ij/plugin/frame/RoiManager.java.html
shows method deleteOnEDT, albeit private.
Is this a possible implementation of the solution to my previous problem
of having to wait for the ImagePlus.show to complete?
// Delete ROI on event dispatch thread
private void deleteOnEDT(final int i) {
try {
EventQueue.invokeAndWait(new Runnable() {
public void run() {
rois.remove(i);
listModel.remove(i);
}
});
} catch (
Exception e) {
}
}
Thanks again,
Fred

Question: from Java, how can an Roi be deleted from the RoiManager
without
the Roi being attached to an ImagePlus? A delete method would be nice,
as
select(ing) the Roi in this case is a side-effect headache and is
superfluous.
Hi Fred,
RoiManager has a method
public void delete(int index)
/** Deletes the ROI at 'index' and updates the display. */
