如何让文本框的宽度自动适合文本? [英] how to let textfield's width auto fit the text?
问题描述
html表格可以自动适合单元格的宽度和文本或内容。列的宽度取决于该列上最宽的单元格。
< table>
< tr>
< td>这可能会很长。< / td>
< / tr>
< tr>
< td>短< / td>
< / tr>
< / table>
但是在as3这是一个问题,我不知道字符串的实际大小,除非我设置它到一个文本框。我不认为这是一个好的策略,使用实际的textfield实例尝试和调整大小,所以让我知道,如果你有一个更好的办法。
textField.autoSize = TextFieldAutoSize.LEFT ;
然后,如果要读取产生的文字大小,可以使用:
var width:Number = textField.textWidth;
var height:Number = textField.textHeight;
recently i was thinking making a component which like html's table tag.
html table can auto fit the cell's width with the text or content in it.and the certain column's width is decided by the widest cell on that column.
<table>
<tr>
<td>this could be very long.</td>
</tr>
<tr>
<td>short</td>
</tr>
</table>
but in as3 this is a problem,i don't know the string's actual size unless i set it to a textfield. i don't think it would be a good strategy to use the actual textfield instance try and resize, so let me know if you have a better way.
First of all, you need to enable auto-sizing:
textField.autoSize = TextFieldAutoSize.LEFT;
Then, if you want to read the resulting text size use can use:
var width:Number = textField.textWidth;
var height:Number = textField.textHeight;
