The user probably wants to replace the find text, so select the find text when the find bar is activated. That is fairly standard behaviour for search text entry. Entering text will replace the current text, but using edit keys (arrows, home, end etc) cancels the selection and enables editing. Signed-off-by:

With support for Python 2 or 3 and PySide 1 or 2 (Qt 4 or 5), it is useful to see what versions are in use.

Committer testing: $ python ~acme/libexec/perf-core/scripts/python/exported-sql-viewer.py ~/c/adrian.hunter/simple-retpoline.db Simply right click and pick "Copy selection", that at this point has just the first line, not expanded, then see what was copied by pressing shift+control+v on a terminal: Call Path,Object,Count,Time (ns),Time (%),Branch Count,Branch Count (%)
