C#仿QQ皮肤－基窗体FunctionFormBase的实现

http://www.cnblogs.com/sufei/archive/2010/03/10/1682847.html

一周要过去了，本来打算多写点的，还是时间不够啊，费话不多说，开始写代码，今天 我们要做的是一个窗体，这个窗体是基于窗体FormBase，就是我们上一节所说到的FormBase与基用户控件FormBase1的实现 里面的FormBase窗体，有关FormBase的实现还请大家去看相应文章，这里不再做过多的说明。

我们先看一下实现的效果吧，第一张图是实现，第二张是正常使用时的样子

下面看一下怎么实现吧，

第一步，创建窗体

我们右键单击文件夹选择添加窗体就行了，名称当时是“FunctionFormBase”，然后单击确定，我们的窗体的大小不需要做任何的修改，那是因为那是继承自窗体FormBase而来的，上节我们讲过了， 他的大小是固定的，所以在这里不用再做设置;

只要这样一行继承的语句就OK了

///<summary>
///FunctionFormBase基窗体
///是构造EntryForm和SkinForm窗体的基础
///</summary>
publicpartialclassFunctionFormBase:FormBase

第二步，窗体的UI布局实现

我们可以看到第一张图，就是窗体的UI布局，相信大家一看就能明白是怎么实现 的，我还是大致的说一下是怎么会事吧。窗体一共是三个Panel

代码实现为：

代码

//
//ptbTopMiddle
//
this.ptbTopMiddle.Dock=System.Windows.Forms.DockStyle.Fill;
this.ptbTopMiddle.Location=newSystem.Drawing.Point(10,0);
this.ptbTopMiddle.Name="ptbTopMiddle";
this.ptbTopMiddle.Size=newSystem.Drawing.Size(669,31);
this.ptbTopMiddle.TabIndex=2;
this.ptbTopMiddle.TabStop=false;

//pnlBackGroup
//
this.pnlBackGroup.BackgroundImageLayout=System.Windows.Forms.ImageLayout.Stretch;
this.pnlBackGroup.Dock=System.Windows.Forms.DockStyle.Fill;
this.pnlBackGroup.Location=newSystem.Drawing.Point(0,31);
this.pnlBackGroup.Name="pnlBackGroup";
this.pnlBackGroup.Size=newSystem.Drawing.Size(689,444);
this.pnlBackGroup.TabIndex=9;

//
//ptbBottomMiddle
//
this.ptbBottomMiddle.Dock=System.Windows.Forms.DockStyle.Fill;
this.ptbBottomMiddle.Location=newSystem.Drawing.Point(10,0);
this.ptbBottomMiddle.Name="ptbBottomMiddle";
this.ptbBottomMiddle.Size=newSystem.Drawing.Size(669,37);
this.ptbBottomMiddle.TabIndex=3;

在ptbTopMiddle左面是一个lblText 右面是两个CommandButton，这个控件是 我自己写的实现方法后面会提到这里不做详细说明，在ptbTopMiddle的两端分别是两个Panel，用来实现窗体的边角，和低部的ptbBottomMiddle 形式是一样的，下面我给出这些控件的初始代码

，我是通过Controls.Remove方法来实现 的，具体的代码如下所示

代码

//移除FormBase现有控件
this.Controls.Remove(this.pnlRight);
this.Controls.Remove(this.pnlLeft);
this.Controls.Remove(this.pnlBackGroup);
this.Controls.Remove(this.pnlCaption);
this.Controls.Remove(this.pnlBottom);

好了我们的布局就到这里吧

第三步，ptbTopMiddle功能实现

因为我们的窗体是一个Panel，所以在移动和鼠标松开时的效果要处理一下，先说一下标题和最小化吧

标题是个Label，我们需要重写定义一下，怎么样来实现呢，我们只要重写一下窗体的Text属性就行了。实现如下

代码

//最小化
publicnewboolMinimizeBox
{
get
{
returnbase.MinimizeBox;
}
set
{
base.MinimizeBox=value;
this.btnMin.Visible=value;
}
}

还有最后一个关闭按钮，这个更简单了，一个Close方法搞定

//关闭按钮
privatevoidbtnClose_Click(objectsender,EventArgse)
{
this.Close();
}

第四步，窗体移动效果

我们的窗体是没有实际的标题的所以 在这里要处理一下移动时的效果

在这里用到了一些Api，具体的说明 请大家参考代码中的类文章Win32类 ，一共有两个方法一个是鼠标移动时的方法

代码

//鼠标松开时
privatevoidcaption_MouseUp(objectsender,MouseEventArgse)
{
if(e.Button==MouseButtons.Right&&((Control)sender).Cursor==Cursors.Default&&e.Y<=SystemInformation.CaptionHeight)
{
Win32.TrackPopupMenu(Win32.GetSystemMenu(Handle,0).ToInt32(),2,Cursor.Position.X,Cursor.Position.Y,0,Handle,0);
}
}

第五步，窗体样式 实现

样式方面第一个重点就是Windows消息的处理，跟其实窗体的实现原理是一样的，不同 是WindowsApi和消息，因为消息在这里还要用的到所以我加了个ref，呵呵 ，ref（ref 关键字使参数按引用传递。其效果是，当控制权传递回调用方法时，在方法中对参数所做的任何更改都将反映在该变量中）

代码

///<summary>
///Windows消息处理
///</summary>
///<paramname="m">Message</param>
protectedoverridevoidWndProc(refMessagem)
{
switch(m.Msg)
{
caseWin32.WM_COMMAND:
Win32.SendMessage(Handle,Win32.WM_SYSCOMMAND,(int)m.WParam,(int)m.LParam);
break;
caseWin32.WM_SYSCOMMAND:
base.WndProc(refm);

if(m.WParam.ToInt64()==Win32.SC_RESTORE)
{
this.Height+=6;
this.Width+=6;
}
elseif(m.WParam.ToInt64()==Win32.SC_MAXIMIZE)
{
Application.DoEvents();
}

break;
default:
base.WndProc(refm);
break;
}
}

这个窗体的样式 除了Windows消息还有一个ReSetFormBitmap方法，因为这个方法是FromBase窗体 里我们在这里需要重写一下，

跟原先的方法实现是一样的，只是我要改几张图片，呵呵

代码

///<summary>
///设置窗体样式
///</summary>
publicoverridevoidReSetFormBitmap()
{
this.pnlCaption.BackgroundImage=Image.FromStream(Shared.AssemblyWinUI.GetManifestResourceStream("CRD.WinUI.Resources.Common.dialog2009.bordertm.bmp"));
this.ptbTopLeft.BackgroundImage=Image.FromStream(Shared.AssemblyWinUI.GetManifestResourceStream("CRD.WinUI.Resources.Common.dialog2009.bordertl.bmp"));
this.ptbTopMiddle.BackgroundImage=Image.FromStream(Shared.AssemblyWinUI.GetManifestResourceStream("CRD.WinUI.Resources.Common.dialog2009.bordertm.bmp"));
this.ptbTopRight.BackgroundImage=Image.FromStream(Shared.AssemblyWinUI.GetManifestResourceStream("CRD.WinUI.Resources.Common.dialog2009.bordertr.bmp"));

this.ptbLeft.BackgroundImage=Image.FromStream(Shared.AssemblyWinUI.GetManifestResourceStream("CRD.WinUI.Resources.Common.dialog2009.borderml.bmp"));
this.ptbRight.BackgroundImage=Image.FromStream(Shared.AssemblyWinUI.GetManifestResourceStream("CRD.WinUI.Resources.Common.dialog2009.bordermr.bmp"));

this.ptbBottomLeft.BackgroundImage=Image.FromStream(Shared.AssemblyWinUI.GetManifestResourceStream("CRD.WinUI.Resources.Common.dialog2009.borderbl.bmp"));
this.ptbBottomMiddle.BackgroundImage=Image.FromStream(Shared.AssemblyWinUI.GetManifestResourceStream("CRD.WinUI.Resources.Common.dialog2009.borderbm.bmp"));
this.ptbBottomRight.BackgroundImage=Image.FromStream(Shared.AssemblyWinUI.GetManifestResourceStream("CRD.WinUI.Resources.Common.dialog2009.borderbr.bmp"));

this.pnlBackGroup.BackgroundImage=Image.FromStream(Shared.AssemblyWinUI.GetManifestResourceStream("CRD.WinUI.Resources.Common.dialog2009.bg.bmp"));

BitmapcloseBitmap=newBitmap(Bitmap.FromStream(Shared.AssemblyWinUI.GetManifestResourceStream("CRD.WinUI.Resources.MainWin.Button.CloseBtn.bmp")));
this.btnClose.NormalImage=closeBitmap.Clone(newRectangle(0,0,37,22),PixelFormat.Format64bppPArgb);
this.btnClose.MouseMoveImage=closeBitmap.Clone(newRectangle(37,0,37,22),PixelFormat.Format64bppPArgb);
this.btnClose.MouseDownImage=closeBitmap.Clone(newRectangle(74,0,37,22),PixelFormat.Format64bppPArgb);

BitmapminBitmap=newBitmap(Bitmap.FromStream(Shared.AssemblyWinUI.GetManifestResourceStream("CRD.WinUI.Resources.MainWin.Button.MinBtn.bmp")));
this.btnMin.NormalImage=minBitmap.Clone(newRectangle(0,0,31,22),PixelFormat.Format64bppPArgb);
this.btnMin.MouseMoveImage=minBitmap.Clone(newRectangle(31,0,31,22),PixelFormat.Format64bppPArgb);
this.btnMin.MouseDownImage=minBitmap.Clone(newRectangle(62,0,31,22),PixelFormat.Format64bppPArgb);

this.CurrentSkinColor=SkinColor.Default;
}
