AS3设置（最大 - ）动画片段的高度，不缩放内容

标签： actionscript-3 flash textfield movieclip

我正在尝试设置文本字段的最大高度，之后只有在滚动时才会显示文本。 我知道，您无法设置文本字段的高度，因为它受到保护。因此，我将Textfield放在一个movieclip中，并想为此设置一个高度。但是，如果我这样做，它会重新调整文本。根据文本的数量，它不仅变得难看，而且显然不可读。

    button200.addEventListener(MouseEvent.CLICK, goBack);
}
while (infobox_MC.numChildren)
{
    infobox_MC.removeChildAt(0);
}

使用其他一些功能，文本字段的alpha将被转换为一个。因此，一旦我执行了正确的功能，它就会被看到，但它会被压扁。

任何帮助将不胜感激

您应该使用numLines来确定文本字段中的行数。

var maxlines:Number = 5;

if( infobox_facts.numlines > maxLines )
{
    // scroll it
}

答案 1 :(得分：0)

好的，所以我找到了我错的地方。

行“* infobox_text.autoSize = TextFieldAutoSize.LEFT; *”阻止我设置textField的宽度和高度。关闭它将允许您指定高度和宽度，并且texfield不需要嵌套在movieclip中。
