Description ratijas 2022-01-25 14:41:24 UTC

SUMMARY

Scrolling position of long a note shouldn't be difficult to restore.

STEPS TO REPRODUCE
1. Add Notes applet.
2. Paste some long (possibly multi-line) text into it.
3. Scroll to the bottom.
4. Reboot.

OBSERVED RESULT
After reboot scrolling position is back to the top of a note.

EXPECTED RESULT
It should be restored along with other properties such as background color and the text itself.

applets/notes: Save/restore scrolling and cursor position

Makes scrolling position persistent, and takes some care to
1. delay restoring until the text is laid out,
2. throttle storage a little, so that we don't use too much I/O.

Component.onDestruction correctly saves the position on exit. It can be
tested via D-Bus by calling method quit() at:

- Session bus: org.kde.plasmashell
- Object path: /MainApplication
- Interface: org.qtproject.Qt.QCoreApplication

Cursor position restoration can be tested by assigning a global shortcut
to an applet, so that it can become focused without actually clicking
on it with a mouse and messing with cursor position. Text selection is
not handled, and I don't think we should even bother with it.
