Subject: Introduce make_visible method
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=cda37efbffb63e2634ea0600fdad2de6a8f9f3ad;p=deliverable%2Fbinutils-gdb.git

Introduce make_visible method

This introduceds the make_visible to tui_win_info and overrides it in
subclasses as appropriate.  This allows the removal of the
tui_win_is_source_type, as it is no longer used.
