DataSet_SelectForProject为什么我无法使用DataLogic.tADDOCList？
它表示对于Object类型它是未定义的。
它还说drawImage不适用于我的图像。此外，我在package com.daveoncode.filters {
/**
* @author Davide Zanotti (davidezanotti@gmail.com)
*/
public class searchFilter extends AbstractFilterDecorator {
/**
* @param target IFilter <p>A reference to a wrapped IFilter object</p>
* @param value Object <p>Value against which the filter is applied</p>
*/
public function searchFilter(target:IFilter, value:Object) {
super(target, value);
}
/**
* Implementation of IFilter interface by overriding the dummy apply() of AbstractFilterDecorator
*/
override public function apply(item:Object):Boolean {
var f:String = "ig";
var packageSearch:RegExp = new RegExp(this._value, f);
var packageMatch:Boolean = packageSearch.test(item.Package);
var itemSearch:RegExp = new RegExp(this._value, f);
var itemMatch:Boolean = packageSearch.test(item.ItemNum);
return this._target.apply(item) && (packageMatch || itemMatch);
}
}
}执行操作时无法public class Movement implements ActionListener {
MazeModel model = new MazeModel();
public void keyPressed(KeyEvent e){ //all of the different movement keys
if(e.getKeyCode() == KeyEvent.VK_W || e.getKeyCode() == KeyEvent.VK_UP){
model.moveUP(model.getUserY());
}
else if(e.getKeyCode() == KeyEvent.VK_A || e.getKeyCode() == KeyEvent.VK_LEFT){
model.moveLEFT(model.getUserX());
}
else if(e.getKeyCode() == KeyEvent.VK_S || e.getKeyCode() == KeyEvent.VK_DOWN){
model.moveDOWN(model.getUserY());
}
else if(e.getKeyCode() == KeyEvent.VK_D || e.getKeyCode() == KeyEvent.VK_RIGHT){
model.moveRIGHT(model.getUserX());
}
}
//no need for either of these at the moment
public void keyRealeased(KeyEvent e){}
public void keyTyped(KeyEvent e){}
//painting the image
protected void paintComponent(Graphics g){
super.paintComponent(g);
g.drawImage("player.png", model.getUserX(), model.getUserY(), this);
}
//every time a key is pressed the screen will repaint the image
public void actionPerformed(ActionEvent ae){
repaint();
}
}
