Unity FairyGUI（八）

一.滚动条

官方文档

• 滚动条不能单独在舞台上进行创建，需要配合滚动视图一起使用

二.滚动视图

• 实质上就是组件勾选了，溢出处理为滚动模式

public class Lesson31 : MonoBehaviour
{
    private void Start()
    {
        GRoot.inst.SetContentScaleFactor(1365, 768,
            UIContentScaler.ScreenMatchMode.MatchHeight);
        var pack = UIPackage.AddPackage("Package1");
        foreach (var item in pack.dependencies)
            UIPackage.AddPackage(item["name"]);
        var com = UIPackage.CreateObject("Package1", "LearnFGUI3").asCom;
        GRoot.inst.AddChild(com);

        var c1 = com.GetChild("n0").asCom;
        var scrollView = c1.scrollPane;

        scrollView.posY = 100;
        scrollView.SetPercY(0.5f,true);
        
        
        print(scrollView.viewWidth);
        print(scrollView.viewHeight);
        print(scrollView.contentWidth);
        print(scrollView.contentHeight);
        
        //设置滑动位置到View中的GObject
        //scrollView.ScrollToView();

        scrollView.touchEffect = true;
        
        scrollView.onScroll.Add(() =>
        {
            //Debug.Log(scrollView.posY);
        });
        scrollView.onScrollEnd.Add(() =>
        {
            Debug.Log("END");
        });
        scrollView.onPullUpRelease.Add(() =>
        {
            Debug.Log("上拉刷新!");
        });
        scrollView.onPullDownRelease.Add(() =>
        {
            Debug.Log("下拉刷新!");
        });
    }
}

• 模拟向背包中创建物品

        var c1 = com.GetChild("n0").asCom;
        var scrollView = c1.scrollPane;

        for (int i = 0; i < 100; i++)
        {
            var go = UIPackage.CreateObject("Package1", "bk");
            c1.AddChild(go);
            go.SetSize(98, 98);
            go.SetPosition(18 + (i % 5) * (98 + 18),18+(i/5)*(98+18),0);
        }

三.列表

官方文档

• 非常强大的功能
• 底层有缓存池，可以设置为虚拟列表和滚动列表，对性能有非常大的优化
  
• 循环列表必须要是单行单列的列表

public class Lesson32 : MonoBehaviour
{
    private void Start()
    {
        GRoot.inst.SetContentScaleFactor(1365, 768,
            UIContentScaler.ScreenMatchMode.MatchHeight);
        var pack = UIPackage.AddPackage("Package1");
        foreach (var item in pack.dependencies)
            UIPackage.AddPackage(item["name"]);
        var com = UIPackage.CreateObject("Package1", "LearnFGUI3").asCom;
        GRoot.inst.AddChild(com);

        var lst = com.GetChild("n2").asList;
        
        //没有缓存机制
         var go1 = lst.AddChild(UIPackage.CreateObject("Package1","quanlity_1"));
         var go2 = lst.AddChild(UIPackage.CreateObject("Package1","quanlity_1"));
        
         lst.RemoveChild(go1);
         go1.Dispose();

        
        //有缓存机制
        var go = lst.AddItemFromPool();
        go.text = "zzs";
        lst.RemoveChildToPool(go);
        lst.AddItemFromPool();
        lst.RemoveChildToPoolAt(0);
        lst.RemoveChildrenToPool(0,50);
        lst.RemoveChildrenToPool();
        

        lst.itemRenderer = (index, item) =>
        {
            item.text = index.ToString();
        };
        lst.onClickItem.Add((conetext) =>
        {
            Debug.Log((conetext.data as GObject).text);
        });
        
        //虚拟列表和循环列表
        //lst.SetVirtual();
        //必须要是单行单列的列表
        lst.SetVirtualAndLoop();
        lst.numItems = 10;
        
        lst.Dispose();
    }
}

四.下拉框

官方文档

• 下拉框是最复杂的组合控件

public class Lesson34 : MonoBehaviour
{
    void Start()
    {
        GRoot.inst.SetContentScaleFactor(1365, 768,
            UIContentScaler.ScreenMatchMode.MatchHeight);
        var pack = UIPackage.AddPackage("Package1");
        foreach (var item in pack.dependencies)
            UIPackage.AddPackage(item["name"]);
        var com = UIPackage.CreateObject("Package1", "LearnFGUI4").asCom;
        GRoot.inst.AddChild(com);

        var comboBox = com.GetChild("n0").asComboBox;
        comboBox.items = new string[]{"zzs","pnb","lzq","wy","ywj"};
        comboBox.values = new string[]{"一","二","三","四","五"};

        comboBox.visibleItemCount = 3;

        comboBox.selectedIndex = 4;
        comboBox.value = "二";
        
        GRoot.inst.HidePopup();
        
        comboBox.onChanged.Add(() =>
        {
            Debug.Log(comboBox.items[comboBox.selectedIndex]);
        });
    }
}
