Description Vladimir Voskresensky 2009-12-15 14:26:12 UTC

We have some annotations from profiler tools and display the metrics on the
left part of editor. 
The issue is that not each line has such metric => there
are parts of file without metrics at all => side bar area is blank.
It is confusing for user to see his text shifted to the right without any reason.

It would be great to have possibility put side bars to the right side of editor (before scrollbar).
For instance we can consider Editor to have "sidebar position" of 10000 and all sidebars after 10000 will be drawn on the right side of editor, not on the left of it

Preffered annotation on the right side

Comment 3 Vladimir Voskresensky 2009-12-16 01:42:37 UTC

Oh, great. You have such support... almost :-)
<attr name="location" stringvalue="East"/>
should do a trick, but for now it is:

java.lang.IllegalArgumentException: Unsupported side bar position, scrollable = true, position=East

Comment 4 Jan Lahoda 2009-12-16 04:11:53 UTC

Well, yes it is unsupported, because the supported scrollable locations (west and north) are directly supported by JScrollPane. JScrollPane does not support custom components in east and south locations (scrollbars are there). Extending the JScrollPane to support east and south locations is non-trivial, AFAIK. The best option to explore, I can currently imagine, is to subclass ScrollPaneLayout, rewrite it to support the two additional locations (subclass of JScrollPane may also be needed, but is not sufficient, I think). As always, a tested patch greatly increases probability of an enhancement to be implemented.

I would love to see this implemented... it gives much more flexibility to presenting annotation.  There is often loads of whitespace on the right margin that could be put to better use.

I am sure that the feature would be used by many if implemented

It looks like the desired functionality is implemented in these two source files (external library):

This old bug may not be relevant anymore. If you can still reproduce it in 8.2 development builds please reopen this issue.

Thanks for your cooperation,
