Subject: Fix hover after press event
X-Git-Url: http://git.silmor.de/gitweb/?a=commitdiff_plain;h=d054755e9e452df05fb590510d25bf4167b97af7;p=konrad%2Fqtdeclarative.git

Fix hover after press event

When a mouse press event was rejected,
we would unconditionally cancel the hover
and claim that the mouse is not contained any more.

Instead check if the mouse left and only then cancel
the hover state.

Task-number: QTBUG-30783
