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