C#仿QQ皮肤－主窗体MainForm和Main的实现

 话说好久没有写了，呵呵，这几周太忙了，写好的新皮肤也没有整合完成，还得让大家再等两周，表示抱歉了，皮肤在使用中存在一些问题和解决方法请大家参才

 皮肤使用须知  (New)   一文章，有什么好的建议或是意见也希望大家提出来，希望能让更多的人参与的皮肤的设计和开发上。

       今天主要是看一下MainForm的实现而Main的实现与之相同，大家可以自己看一下源代码，或者我会在下次文章里提到一些，这个窗体是一个很重要的窗体，因为关于换肤的方法要在这里引用，使用皮肤的前提也是要使用这个窗体，所以是一个很重要的窗体，算是一个使用皮肤控件的基础吧;

     我们先看 一下它的布局吧

   

大家应该能看的出来，左上角是一个      Panel是用来做窗体的标题的，而右面的三个CommandButton是用来实现，最小化，最大化和关闭按钮的，

定部的Panel是工具一栏，而下面而是窗体 的主体部分了

   实现之后的效果是这样的

在这里还要感谢一位网友提供的图片素材，在这里谢谢了，最新的皮肤不会带有这些图片，但是上面具有这具功能 ，大家可以直接添加，因是作者留有版权，呵呵

  我们来看实现吧 所用的到图片大家可以在源代码里找到，我这里给出引用的图片代码大家可以根据代码查找

先来看一下构造器吧

 this.SetStyle(ControlStyles.DoubleBuffer | ControlStyles.AllPaintingInWmPaint, true);
            InitializeComponent();
            this.Controls.Remove(this.pnlBackground);
            this.Controls.Remove(this.pnlRight);
            this.Controls.Remove(this.pnlLeft);
            this.Controls.Remove(this.pnlBottom);
            this.Controls.Remove(this.pnlCaption);

老样子还是先移除之前基础窗体上的控件

在这里我实现 了一个接口IMainForm 用来定义窗体的规范，

大家也可以看一下这个接口的主要代码

 //窗体接口
    public interface IMainForm
    {
        void PerformChangeSkinColor();
        void PerformChangeSkinColor(SkinColor skinColor);
        void PerformChangeBackgroundStripe(BackgroundStripe backgroundStripe);
        void PerformAllFormChangeSkinColor(SkinColor skinColor);

        SkinColor CurrentSkinColor {get;set;}

        Color MainFormBackGroundColor { get; }
        Color MainFormBackGroundColor2 { get; }
        Color ControlBackColor { get; }
        Color ControlBorderBackColor { get; }
    }

本窗是继承自FormBase窗体而来的，如果大家看过它的实现应该不难明白为什么要这样处理构造器了

处理窗体标题栏的方法

 public override string Text
        {
            get
            {
                return base.Text;
            }
            set
            {
                base.Text = value;
                if (lblText != null)
                    this.lblText.Text = value;
            }
        }

上面Panel皮肤处理

主体Panel处理

  public Color ControlBackColor
        {
            get
            {
                if (this.pnlBackground.BackgroundImage != null)
                {
                    Bitmap bitmap = new Bitmap(this.pnlBackground.BackgroundImage);
                    return bitmap.GetPixel(20, 30);
                }
                else
                {
                    return SystemColors.Control;
                }
            }
        }

        public Color ControlBorderBackColor
        {
            get
            {
                if (this.ptbTopMiddle.BackgroundImage != null)
                {
                    Bitmap bitmap = new Bitmap(this.ptbTopMiddle.BackgroundImage);
                    return bitmap.GetPixel(1, 80);
                }
                else
                {
                    return SystemColors.Control;
                }
            }
        }

        public Color MainFormBorderColor
        {
            get
            {
                if (this.ptbTopLeft.BackgroundImage != null)
                {
                    Bitmap bitmap = new Bitmap(this.ptbTopLeft.BackgroundImage);
                    return bitmap.GetPixel(1, 20);
                }
                else
                {
                    return SystemColors.Control;
                }
            }
        }

        

下面是Windows消息的处理方法

protected override void WndProc(ref Message m)
        {
            switch (m.Msg)
            {
                case Win32.WM_COMMAND:
                    Win32.SendMessage(Handle, Win32.WM_SYSCOMMAND, (int)m.WParam, (int)m.LParam);
                    break;

                    if (m.WParam.ToInt64() == Win32.SC_RESTORE)
                    {
                        this.Height += 6;
                        this.Width += 6;
                        this.btnMaxResore.NormalImage = maxBitmap.Clone(new Rectangle(0, 0, 32, 22), PixelFormat.Format64bppPArgb);
                        this.btnMaxResore.MouseMoveImage = maxBitmap.Clone(new Rectangle(32, 0, 32, 22), PixelFormat.Format64bppPArgb);
                        this.btnMaxResore.MouseDownImage = maxBitmap.Clone(new Rectangle(64, 0, 32, 22), PixelFormat.Format64bppPArgb);
                        this.btnMaxResore.ToolTip = "还原";

                        Shared.ChangeSkinColor(Shared.CurrentSkinColor, this.btnMaxResore, true);
                    }
                    else if (m.WParam.ToInt64() == Win32.SC_MAXIMIZE)
                    {
                        Application.DoEvents();
                        this.btnMaxResore.NormalImage = resoreBitmap.Clone(new Rectangle(0, 0, 32, 22), PixelFormat.Format64bppPArgb);
                        this.btnMaxResore.MouseMoveImage = resoreBitmap.Clone(new Rectangle(32, 0, 32, 22), PixelFormat.Format64bppPArgb);
                        this.btnMaxResore.MouseDownImage = resoreBitmap.Clone(new Rectangle(64, 0, 32, 22), PixelFormat.Format64bppPArgb);
                        this.btnMaxResore.ToolTip = "最大化";

                        Shared.ChangeSkinColor(Shared.CurrentSkinColor, this.btnMaxResore, true);
                    }

                    break;
                default:
                    base.WndProc(ref m);
                    break;
            }
        }



代码
  public Color MainFormBackGroundColor
        {
            get
            {
                if (this.ptbTopLeft.BackgroundImage != null)
                {
                    Bitmap bitmap = new Bitmap(this.ptbTopLeft.BackgroundImage);
                    this.BackColor = bitmap.GetPixel(20, 15);
                    return this.BackColor;
                }
                else
                {
                    return SystemColors.Control;
                }
            }
        }

 OnLoad方法这里加载 了一些默认要显示的图片

 protected override void OnLoad(EventArgs e)
        {
            this.Controls.Add(this.pnlBackground);
            this.Controls.Add(this.pnlRight);
            this.Controls.Add(this.pnlLeft);
            this.Controls.Add(this.pnlBottom);
            this.Controls.Add(this.pnlCaption);

            if (!DesignMode)
            {
                this.Hide();
            }

            resoreBitmap = new Bitmap(Bitmap.FromStream(Shared.AssemblyWinUI.GetManifestResourceStream("CRD.WinUI.Resources.MainWin.Button.RestrBtn.bmp")));
            maxBitmap = new Bitmap(Bitmap.FromStream(Shared.AssemblyWinUI.GetManifestResourceStream("CRD.WinUI.Resources.MainWin.Button.MaxBtn.bmp")));

            skinButton = new Bitmap(Bitmap.FromStream(Shared.AssemblyWinUI.GetManifestResourceStream("CRD.WinUI.Resources.MainWin.Button.ColorBtn.png")));
            menuButton = new Bitmap(Bitmap.FromStream(Shared.AssemblyWinUI.GetManifestResourceStream("CRD.WinUI.Resources.MainWin.Button.MenuBtn.png")));

            this.lblText.Text = this.Text;

            Application.DoEvents();

            base.OnLoad(e);

            if (!DesignMode)
            {
                int maxWidth = Screen.GetWorkingArea(this).Width + 15;
                int maxHeight = Screen.GetWorkingArea(this).Height + 8;
               
                this.MaximumSize = new Size(SystemInformation.WorkingArea.Size.Width + 15, SystemInformation.WorkingArea.Size.Height + 8);
            }

            Application.DoEvents();
            this.Show();
        }

因为我们是窗体 是没有标题栏的，所 以我们要处理一个当拖动上面Panel时要让窗体要着移动，还有就 是在移动的过程中要刷新一下皮肤

强说这个窗体是很重要的一个，但是说白了这个窗体很简单，只要看代码应该都 能明白是什么意思了，大家如果有什么不懂的地方可以用源代码调试一下，或者给我留言;下周开始升级解决的一些问题，这周忙于工作，有空整合一下希望大家多多提建议
