问题
Here is another question regarding JavaMe and LWUIT.
I need to manually scroll TextArea with help of methods or etc. TextArea contains methods responsible only for obtaining current position of scrolling and its enable and disable.
How can I do this?
I solved problem by using inheritance from TextArea and delegation protected methods of scrolling (setScrollX and setScrollY accordingly). Thanks to all!
回答1:
TextArea extends TextField. In the TextField class there is the setCursorPosition method. So my suggestion is to use this method and you loop through the TextArea content until a certain position you desire is reached.
回答2:
You can use scrollRectToVisible() which is often more convenient than scrollY and adds smooth scrolling animation.
