移动表（拥有滚动窗格）中的小部件后，Libgdx Scrollpane滚动不足

Question

我有个问题。在移动了表中的小部件（拥有滚动窗格）之后，Libgdx Scrollpane滚动不足。

这是我的代码示例。

Table scrollPaneTable = new Table();

Scrollpane itemsScrollPane = new ScrollPane(scrollPaneTable);

...

mainTable.add(itemsScrollPane).width(WIDTH).height(HEIGHT);

...

//adding items in the scrollPaneTable

// everything is work perfect at this moment.

....

for (final Actor actor : scrollPaneTable.getChildren()) {

...

actor.moveBy(MAIN_QUEST_ITEM_WIDTH * chapterData.quests.size * direction, 0);

...

}

...

//after I move actor in the table, scrollpane scrolls like before, I can't reach the last items.

谢谢你的帮助。
