Subject: Improved qWaitForWindowShown().
X-Git-Tag: qt-v5.0.0-alpha1~269
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0b70d8c6afb525d80cf4f1fc788e1a5947f0b152;p=profile%2Fivi%2Fqtbase.git

Improved qWaitForWindowShown().

Made faster by actually waiting for the window to be exposed, using
similar waiting logic as qWait(). Should speed up autotests that use it
quite a bit.
