Flash as3：将鼠标悬停的文本颜色更改为复选框

Question

因此，此代码创建一个复选框，旁边有一些文本。

我该如何去改变它，以便当有人将鼠标悬停在复选框旁边的文本上时，文本会变色？

还有更多的软件包与此...如果需要帮助解决这个问题，请让我知道，我也可以发布这些。

谢谢！

你可以做，使用text_field.textColor或使用TextFormat。

使用text_field.textColor：

var hover_color:Number = 0xff0000 
var out_color:Number = 0x666666 

text_field.addEventListener(MouseEvent.MOUSE_OVER, function(e:MouseEvent) 
{ 
    text_field.textColor = hover_color 
}) 
text_field.addEventListener(MouseEvent.MOUSE_OUT, function(e:MouseEvent) 
{ 
    text_field.textColor = out_color 

}) 

使用TextFormat：

var text_format:TextFormat = new TextFormat() 
    text_format.color = out_color 

text_field.defaultTextFormat = text_format 

text_field.addEventListener(MouseEvent.MOUSE_OVER, function(e:MouseEvent) 
{ 
    text_format.color = hover_color 
    text_field.setTextFormat(text_format) 
}) 
text_field.addEventListener(MouseEvent.MOUSE_OUT, function(e:MouseEvent) 
{ 
    text_field.setTextFormat(text_field.defaultTextFormat) 

})
