    Description

      We faced with the following problem:  QML list view scrolls if scrolling starts from list header. To prevent it we tried to place MouseArea on a header and set preventStealing to true for it.

      It worked for some cases, but if that MouseArea contains Button as a child, list scroll can be started from this button. So MouseArea allows ListView to steal events from its child.

      Code sample is in attachment.
