Subject: windows: Use FindWindow to locate the window related to the timer
X-Git-Tag: dali_2.0.8~2^2~2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=refs%2Fchanges%2F78%2F250178%2F3;p=platform%2Fcore%2Fuifw%2Fdali-adaptor.git

windows: Use FindWindow to locate the window related to the timer

If our window is not the foreground window, GetActiveWindow() will
return a null handle, which causes the call to SetTimer to ignore the
given timer ID.

We solve this by calling FindWindow() passing the window class name when
GetActiveWindow returns null.
