LWUIT滚动 [英] LWUIT Scrolling

问题描述

这是有关JavaMe和LWUIT的另一个问题.

Here is another question regarding JavaMe and LWUIT.

我需要借助方法等手动滚动TextArea.TextArea包含仅负责获取当前滚动位置及其启用和禁用的方法.

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.

我该怎么做?

我通过使用来自TextArea的继承和受委托保护的滚动方法(相应地使用setScrollX和setScrollY)解决了问题.谢谢大家！

I solved problem by using inheritance from TextArea and delegation protected methods of scrolling (setScrollX and setScrollY accordingly). Thanks to all!

推荐答案

TextArea扩展了TextField.在TextField类中，有一个setCursorPosition方法.因此，我的建议是使用此方法，然后遍历TextArea内容，直到达到所需的特定位置为止.

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.
