92 TapHandler-based button is placed near the screen edge, it can be used-

166-
167 Unlike the exclusive grab, multiple PointerHandlers can have passive grabs-
168 simultaneously. This means that each of them will receive further events-
169 when the \a point moves, and when it is finally released. Typically a-
170 PointerHandler should acquire a passive grab as soon as a point is pressed,-
171 if the handler's constraints do not clearly rule out any interest in that-
172 point. For example, DragHandler needs a passive grab in order to watch the-
173 movement of a point to see whether it will be dragged past the drag-
174 threshold. When a handler is actively manipulating its \l target (that is,-
175 when \l active is true), it may be able to do its work with only a passive-
176 grab, or it may acquire an exclusive grab if the gesture clearly must not-
177 be interpreted in another way by another handler.-
