Subject: bpo-34275: Make IDLE calltips always visible on Mac.  (GH-8639)
X-Git-Tag: v3.6.7rc1~132
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=363105e546709339e3419ada9daf5efa0b3b1e18;p=thirdparty%2FPython%2Fcpython.git

bpo-34275: Make IDLE calltips always visible on Mac.  (GH-8639)


Some MacOS-tk combinations need .update_idletasks().
The call is both unneeded and innocuous on Linux and Windows.
Patch by Kevin Waltzer.
(cherry picked from commit 9beaef6225cdae972b1cccd5310828cc29bf9d33)
