When comparing two files in Diff tool, the editor scrolls at the beginning of the files after swapping of left and right windows by pressing Swap button. When I'm merging changes from file A to B, I often need to back-merge changes from B to A, so I use Swap in that case. As a workaround for scrolling, I have to remember the line number and then go to that line after swap, which is quite annoying. It would be nice if the editor in Diff tool would remember the scolled position and it would not scroll at the beginning.
Sorry, this is the best i can do with the current API diff view provides. Note that even with a better API it would not be 100% reliable because of the level of asynchronoucity the diff view uses. When swapped diff at least jumps to the current difference index it was previously showing, so at least it gets you closer to the exact location. core-main #749861e9a90b
Integrated into 'main-silver', will be available in build *201508020002* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress) Changeset: http://hg.netbeans.org/main-silver/rev/749861e9a90b User: Ondrej Vrabec <ovrabec@netbeans.org> Log: #251981 - Swap in Diff should not scroll at the beginning of the files Remember at least the current difference index and on swap jump to it.
Thanks at least for this workaround, it will ease the work little bit.
