flex toolTip样式设置
需要3个文件。一个是样式类,一个样式文件,一个是mxml文件。
●MyToolTip.as
package{
import mx.core.UITextField;
import mx.skins.halo.ToolTipBorder;
import mx.controls.ToolTip;
public class MyToolTip extends ToolTipBorder {
override protected function updateDisplayList(unscaledWidth:Number,
unscaledHeight:Number):void{
var toolTip:ToolTip = (this.parent as ToolTip);
var textField:UITextField = toolTip.getChildAt(1) as UITextField;
textField.htmlText = textField.text;
var calHeight:Number = textField.height;
calHeight += textField.y*2;
calHeight += textField.getStyle("paddingTop");
calHeight += textField.getStyle("paddingBottom");
var calWidth:Number = textField.textWidth;
calWidth += textField.x*2;
calWidth += textField.getStyle("paddingLeft");
calWidth += textField.getStyle("paddingRight");
super.updateDisplayList(calWidth, calHeight);
}
}
}
●style.css

font-family: verdana;
font-size: 14px;
color: #000000;
