|
// - On Windows,
|
|
// autoscrolling and selection-expansion happens only once per
|
|
// each mouse-dragged event received, and only for some ammount,
|
|
// not to the end. So, we have to drag mouse repeatedly.

|
|
// only 1 mouse-dragged event is required for autoscrolling/
|
|
// selection-expanding to commence. Once commenced, it will
|
|
// continue to the end of text (provided that mouse-button is
|
|
// hold pressed), but it may take hardly predictable ammount of
|
|
// time. However, repeatedly dragging mouse seems perfectly help
|
|
// here, instead of having to use 'Thread.sleep( ??? )'.
|
|
// Note: It's required here to move mouse 2 times to receive the
|
|
// 1-st drag-event. After 1-st movement, only mouse-exited event
|
|
// will be generated. If mouse was released after first movement
|
|
// here, we would even get mouse-clicked event (at least for now,

|
// and this is probably a bug). But, starting with 2nd iteration,

// all events received will be mouse-dragged events.
