MOUSEMOVE_DELTA

Detailed Description

These constants should be used in InputEvent and only movements bigger than MOUSEMOVE_DELTA_TABLET or MOUSEMOVE_DELTA_MOUSE should be processed.
Here is an example from the material preview:

  Float GetMouseMoveDelta()
  {
    return GeIsTabletMode() ? MOUSEMOVE_DELTA_TABLET : MOUSEMOVE_DELTA_MOUSE;
  }
 
Bool MaterialPreviewArea::InputEvent(const BaseContainer& msg)
{
  ...
  Float rMinDelta = GetMouseMoveDelta();
  Float rTotalDeltaX = 0, rTotalDeltaY = 0;
  Float rDeltaX, rDeltaY;
  while (MouseDrag(&rDeltaX, &rDeltaY, nullptr)==MOUSEDRAGRESULT_CONTINUE)
  {
    rTotalDeltaX += rDeltaX;
    rTotalDeltaY += rDeltaY;
    if ((rDeltaX == 0 && rDeltaY == 0) ||
    (!bRotated && Abs(rTotalDeltaX) < rMinDelta && Abs(rTotalDeltaY) < rMinDelta))
    {
      GeSleep(10);
      continue;
    }
    ...
    bRotated = true;
    bRestart = true;
  }
}
