winforms刷新多个面板

Question

我正在构建一个扑克游戏，我需要同时展示多个扑克牌。我可以显示 1、3、5 或 10。

我有 1 个将一直显示的主手牌，我会根据玩家想要玩的手牌数量激活不同的视图。

我有 2 个主面板（main_hand_panel 和 extra_hands_panel）

我将所有面板添加到 List 中，并在需要时调用 ShowHand。

我像这样将第一手牌添加到 main_hand_panel：

Point startPosition = new Point(0, 0);
ComponentResourceManager resources = new ComponentResourceManager(typeof(MainScreen));
var mainPokerHand = new PokerPanel(startPosition, main_hand_panel.Size, offset, cardSize);
mainPokerHand.Initialize(resources);
this.main_hand_panel.Controls.Add(mainPokerHand);
allHands.Add(mainPokerHand);

然后根据我显示的屏幕，我绘制并添加像这样的额外手（显示五手示例）

public void DrawFivePlay(ComponentResourceManager resources)
{
    Point startPosition = new Point(0, 0);
    var containerSize = extra_hands_panel.Size;
    containerSize.Height = Convert.ToInt32(containerSize.Height / 2);
    containerSize.Width = Convert.ToInt32(containerSize.Width / 2);
    for (int i = 0; i < 2; i++)
    {
        startPosition.Y = containerSize.Height * i;
        var pokerHand = new PokerPanel(startPosition, containerSize, scale(offset, .30), scale(cardSize, .8));
        pokerHand.Initialize(resources);
        this.extra_hands_panel.Controls.Add(pokerHand);
        allHands.Add(pokerHand);
    }

    startPosition.X = containerSize.Width;
    startPosition.Y = 0;
    for (int i = 0; i < 2; i++)
    {
        startPosition.Y = containerSize.Height * i;
        var pokerHand = new PokerPanel(startPosition, containerSize, scale(offset, .30), scale(cardSize, .8));
        pokerHand.Initialize(resources);
        this.extra_hands_panel.Controls.Add(pokerHand);
        allHands.Add(pokerHand);
    }
}

当我准备好展示手牌时，我调用reveal_click，它会遍历List中的所有手牌并显示它们。

private void reveal_Click(object sender, EventArgs e)
{
    foreach (var hand in allHands)
    {
        hand.ShowHand();
    }
    Application.DoEvents();
}

有趣的部分是它不显示主手，它会显示所有其他手，但它显示第一手的唯一时间是程序刚刚启动并且我们只玩一只手。如果我显示任何其他播放选项，第一手牌将不再显示。

这是 PokerPanel 代码：

namespace TEX_DrawPoker
{
    public class PokerPanel : Panel
    {
        private PictureBox pictureBox1_5;
        private PictureBox pictureBox1_1;
        private PictureBox pictureBox1_2;
        private PictureBox pictureBox1_3;
        private PictureBox pictureBox1_4;

        Timer drawTimer = new Timer();
        int timerTick = 0;
        string[] pokerHand;

        Size panelSize = new Size(5*229, 275);
        Size cardSize = new Size(146, 202);
        Point startPosition = new Point(0, 3);
        Point firstCardPosition = new Point(0, 0);
        Point offset  = new Point(160, 0);

        public PokerPanel(Point _startPosition,Size _panelSize, Point _offset, Size _cardSize)
        {
            drawTimer.Tick += new EventHandler(startDisplay);
            drawTimer.Interval = 100;
            drawTimer.Enabled = false;

            panelSize = _panelSize;
            cardSize = _cardSize;
            offset = _offset;
            startPosition = _startPosition;
        }

        public void startDisplay(object sender, EventArgs e)
        {
            switch (timerTick)
            {
                case 0:
                    this.pictureBox1_1.Image = (Image)(new Bitmap(Image.FromFile(".\\img\\cards\\" + pokerHand[timerTick] + ".png"), cardSize));
                    break;
                case 1:
                    this.pictureBox1_2.Image = (Image)(new Bitmap(Image.FromFile(".\\img\\cards\\" + pokerHand[timerTick] + ".png"), cardSize));
                    break;
                case 2:
                    this.pictureBox1_3.Image = (Image)(new Bitmap(Image.FromFile(".\\img\\cards\\" + pokerHand[timerTick] + ".png"), cardSize));
                    break;
                case 3:
                    this.pictureBox1_4.Image = (Image)(new Bitmap(Image.FromFile(".\\img\\cards\\" + pokerHand[timerTick] + ".png"), cardSize));
                    break;
                case 4:
                    this.pictureBox1_5.Image = (Image)(new Bitmap(Image.FromFile(".\\img\\cards\\" + pokerHand[timerTick] + ".png"), cardSize));
                    break;
            }

            if (timerTick >= 4)
            {
                drawTimer.Stop();
                timerTick = 0;
            }
            else
            {
                timerTick++;
            }
        }

        public void ShowHand()
        {
            pokerHand = Deck.shuffle();
            drawTimer.Start();
        }

        public void Reset()
        {

我还使用计时器来显示卡片，以便它们交错排列。

任何帮助将不胜感激。

谢谢，

发现我的问题， 我没有清除手动更改之间的控件，因此我试图更新后台的面板。 Controls.Clear() 在移动到下一手之前为我解决了这个问题。对不起，长篇大论一无所获。 :(

您是否考虑过刷新整个表单？

Form1.Refresh();

或者只刷新面板

PokerPanel.Refresh();
