我是AS3编码的新手,我想要一些帮助。我收到了一个任务,我必须编写一个乘法表(10行,10列)。我已设法对表进行编码,但我需要帮助才能添加所需的数字,而无需手动添加文本。 它应该看起来像这样;
有人可以帮助我完成这项任务吗? 这是我的代码:
var xColumns:uint=10;
var xRows:uint=10;
var _columnWidth:Number=40;
var _rowHeight:Number=40
var _width:Number=_columnWidth*xColumns;
var _height:Number=_rowHeight*xRows;
graphics.lineStyle(2, 0x0000ff, 1);
for(var i:int=1; i<=xColumns; i++){
graphics.moveTo(i*_columnWidth,0);
graphics.lineTo(i*_columnWidth,_height);
}
for(i=1; i<=xRows; i++){
graphics.moveTo(0,i*_rowHeight);
graphics.lineTo(_width,i*_rowHeight);
}
答案 0 :(得分:0)
这是“Cell”类的样本:
package
{
import flash.display.Graphics;
import flash.display.Sprite;
import flash.text.TextField;
import flash.text.TextFieldAutoSize;
public class Cell extends Sprite
{
//---------------------------------------
protected var m_oLabel:TextField;
protected var m_nWidth:Number = 20;
protected var m_nHeight:Number = 20;
protected var _backgroundColor:Number;
//---------------------------------------
//Group: CONSTRUCTOR
public function Cell()
{
super();
m_oLabel = new TextField();
m_oLabel.text = "999";
m_oLabel.autoSize = TextFieldAutoSize.CENTER;
addChild(m_oLabel);
setLabel("999");
}
//--------------------------------------------------//
// PUBLIC PUBLIC PUBLIC PUBLIC //
//--------------------------------------------------//
public function setLabel(p_sLabel:String):void
{
m_oLabel.text = p_sLabel || "";
updateLayout();
}
public function get backgroundColor():Number
{
return _backgroundColor;
}
public function set backgroundColor(value:Number):void
{
_backgroundColor = value;
redraw();
}
//------------------- OVERRIDDEN -------------------//
override public function get width():Number
{
return m_nWidth;
}
override public function set width(value:Number):void
{
m_nWidth = value;
updateLayout();
redraw();
}
override public function get height():Number
{
return m_nHeight;
}
override public function set height(value:Number):void
{
m_nHeight = value;
updateLayout();
redraw();
}
//--------------------------------------------------//
// PRIVATE/PROTECTED PRIVATE/PROTECTED //
//--------------------------------------------------//
protected function updateLayout():void
{
//adjust layout
if (m_oLabel)
{
m_oLabel.x = width * .5 - m_oLabel.width * .5;
m_oLabel.y = height * .5 - m_oLabel.height * .5;
}
}
protected function redraw():void
{
var g:Graphics = this.graphics;
g.beginFill(_backgroundColor);
g.drawRect(0, 0, width, height);
g.endFill();
}
//------------------- OVERRIDDEN -------------------//

}
}
和用法:
var container:Sprite = new Sprite();
addChild(container);
container.x = 10;
container.y = 10;
for (var i:int = 0; i <= 10; i++)
{
for (var j:int = 0; j <= 10; j++)
{
var cell:Cell = new Cell();
if (i == 0 || j == 0)
{
//headers
cell.setLabel(Math.max(i, j).toString());
cell.backgroundColor = 0x808080;
}
else
{
var mul:Number = i * j;
cell.setLabel(mul.toString());
cell.backgroundColor = 0xC0C0C0;
}
container.addChild(cell);
cell.x = cell.width * j;
cell.y = cell.height * i;
}
}
看起来像这样:
新类“Cell”为您提供灵活性和封装代码,用于创建单个表格单元格。在我的例子中,它只是textfield的容器,并且能够绘制背景。我创建了公共方法/访问器,允许修改单元格的“功能”(即TextField中显示的内容和背景颜色是什么)。我不得不覆盖默认的宽度/高度行为,否则它会返回它的内容大小,这取决于TextField的内容和大小,在表中我们需要稳定的大小。
