112 // - On Windows,
113 // autoscrolling and selection-expansion happens only once per
114 // each mouse-dragged event received, and only for some ammount,
115 // not to the end. So, we have to drag mouse repeatedly.
116 // - on X,
117 // only 1 mouse-dragged event is required for autoscrolling/
118 // selection-expanding to commence. Once commenced, it will
119 // continue to the end of text (provided that mouse-button is
120 // hold pressed), but it may take hardly predictable ammount of
121 // time. However, repeatedly dragging mouse seems perfectly help
122 // here, instead of having to use 'Thread.sleep( ??? )'.
123 // Note: It's required here to move mouse 2 times to receive the
124 // 1-st drag-event. After 1-st movement, only mouse-exited event
125 // will be generated. If mouse was released after first movement
126 // here, we would even get mouse-clicked event (at least for now,
127 // and this is probably a bug). But, starting with 2nd iteration,
128 // all events received will be mouse-dragged events.
