StyledText可見行數

Question

我想知道StyledText實際顯示了多少行。這可能嗎？

謝謝。

試試這個代碼：

// The index of the last (possibly only partially) visible line of the widget 
int bottomIndex = JFaceTextUtil.getPartialBottomIndex((StyledText)widget); 
// The index of the first (possibly only partially) visible line of the widget 
int topIndex = JFaceTextUtil.getPartialTopIndex((StyledText)widget); 


int visibleLines = bottomIndex - topIndex;
