MagicLibrary.dll控件功能中昨天写了个Menu的实现，全部以代码方式实现的一个例子。
在MagicLibrary.dll中，还一TabControl控件。
今天以拖拉方式（工具方法拖出）实现TabControl，其中加有Menu例子。
例子源码下载：/Files/HD/MagicLibrary_Demo/TabControlDemo.rar
截图如下：
例图一：
例图二：加入TabPage
例图三：关才已选择的TabPage
例图四：在已选择的TabControl中的RichTextBox控件右键菜单
例图五：TabControl控件的PositionTop属性设为flase
操作示例：
（界面设计）
项目中加入MagicLibrary.dll（包括解决方案资源管理器、工具箱中）。
项目中包括两个Form，分别为：Form1、Form2，Form1为起始Form。
打开Form1，在窗口设计器中从工具箱中拖入刚加入的控件：MenuControl，把MenuControl的Dock属性设为：Top，Name属性为：_topMenu，PositionTop属性设为：true，ShowArrows属性设为：true，ShowClose属性设为：true，ShrinkPagesToFit属性设为：false。接着再从工具箱中拖入：TabControl，把TabControl控件的Dock属性设为：Fill，Name属性为：_tabControl。
打开Form2，在窗口设计器中从工具箱中拖入控件：RichTextBox，把RichTextBox的Dock属性设为：Fill，Name属性设为：rtxContent
一：Form1
（代码实现）
打开Form1的代码设计器，在Form1的构造函数中加入：this.SetupMenu();
见源码：
public Form1()
{
//
// Windows 窗体设计器支持所必需的
//
InitializeComponent();
//加入菜单
this.SetupMenu();
}
接着复制这段代码到设计器中：
/** <summary>
/// 加入下拉菜单
/// </summary>
protected void SetupMenu()
{
Crownwood.Magic.Menus.MenuCommand top1 = new Crownwood.Magic.Menus.MenuCommand( "&PageControls" );
Crownwood.Magic.Menus.MenuCommand top1_1 = new Crownwood.Magic.Menus.MenuCommand( "&AddPage",new EventHandler( OnAddPageSelected ) );
Crownwood.Magic.Menus.MenuCommand top1_2 = new Crownwood.Magic.Menus.MenuCommand( "&RemovePage",new EventHandler( OnColseSelected ) );
Crownwood.Magic.Menus.MenuCommand top1_3 = new Crownwood.Magic.Menus.MenuCommand( "&Exit",new EventHandler( OnExitSelected ) );
top1.MenuCommands.AddRange( new Crownwood.Magic.Menus.MenuCommand[]{ top1_1,top1_2,top1_3 } ); Crownwood.Magic.Menus.MenuCommand top2 = new Crownwood.Magic.Menus.MenuCommand( "&TabControl" );
Crownwood.Magic.Menus.MenuCommand top2_1 = new Crownwood.Magic.Menus.MenuCommand( "&Top",new EventHandler( OnTopSelected ) );
Crownwood.Magic.Menus.MenuCommand top2_2 = new Crownwood.Magic.Menus.MenuCommand( "&Buttom",new EventHandler( OnButtomSelected ) );
top2.MenuCommands.AddRange( new Crownwood.Magic.Menus.MenuCommand[]{ top2_1,top2_2 } ); this._topMenu.MenuCommands.AddRange( new Crownwood.Magic.Menus.MenuCommand[]{ top1,top2 } );
this._tabControl.MouseUp += new MouseEventHandler( OnMouseUpTabPage );
} /** <summary>
/// 加入页面
/// </summary>
protected void AddPage()
{
Form2 f2 = new Form2();
System.Windows.Forms.Control ctlForm = f2;
Crownwood.Magic.Controls.TabPage tp = new Crownwood.Magic.Controls.TabPage( "Page"+this._tabControl.TabPages.Count.ToString(),ctlForm );
this._tabControl.TabPages.Add( tp ).Selected = true;
} protected void OnExitSelected( object sender , EventArgs e )
{
DialogResult dr = MessageBox.Show( "Are you sure exit application?","Warning",MessageBoxButtons.YesNo,MessageBoxIcon.Warning );
if ( dr == DialogResult.Yes )
{
Application.Exit();
}
} protected void OnTopSelected( object sender,EventArgs e )
{
this._tabControl.PositionTop = true;
} protected void OnButtomSelected( object sender , EventArgs e )
{
this._tabControl.PositionTop = false;
} protected void OnAddPageSelected( object sender , EventArgs e )
{
this.AddPage();
} protected void OnMouseUpTabPage( object sender , System.Windows.Forms.MouseEventArgs e )
{
if ( this._tabControl.TabPages.Count>0 && e.Button == MouseButtons.Right && this._tabControl.SelectedTab.Selected )
{
Crownwood.Magic.Menus.MenuControl muMenu = new Crownwood.Magic.Menus.MenuControl();
Crownwood.Magic.Menus.MenuCommand menu1 = new Crownwood.Magic.Menus.MenuCommand( "&SavePage" );
Crownwood.Magic.Menus.MenuCommand menu2 = new Crownwood.Magic.Menus.MenuCommand( "&Close",new EventHandler( OnColseSelected ) ); Crownwood.Magic.Menus.PopupMenu pm = new Crownwood.Magic.Menus.PopupMenu();
pm.MenuCommands.AddRange( new Crownwood.Magic.Menus.MenuCommand[]{ menu1,menu2 } );
pm.TrackPopup( this._tabControl.PointToScreen( new Point( e.X,e.Y ) ) );
}
} protected void OnColseSelected( object sender , EventArgs e )
{
if ( this._tabControl.TabPages.Count > 0 )
{
this._tabControl.TabPages.Remove( this._tabControl.SelectedTab );
}
}
（添加事件）
打开Form1窗口设计器，选中TabControl控件，向控件加入MouseUp事件：
/** <summary>
/// 单击TabControl关闭按钮时关闭已选择的TabPage
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void _tabControl_ClosePressed(object sender, System.EventArgs e)
{
if ( this._tabControl.TabPages.Count > 0 )
{
this._tabControl.TabPages.Remove( this._tabControl.SelectedTab );
}
}二：Form2
打开Form2窗口设计器，选中RichTextBox，为RichTextBox控件添加MouseUp事件：
private void rtxContent_MouseUp(object sender, System.Windows.Forms.MouseEventArgs e)
{
if ( e.Button == MouseButtons.Right )
{
System.Windows.Forms.RichTextBox rt = ( RichTextBox )sender;
Crownwood.Magic.Menus.MenuControl muMenu = new Crownwood.Magic.Menus.MenuControl();
Crownwood.Magic.Menus.MenuCommand menu1 = new Crownwood.Magic.Menus.MenuCommand( "&Copy" );
Crownwood.Magic.Menus.MenuCommand menu2 = new Crownwood.Magic.Menus.MenuCommand( "&Cut" ); Crownwood.Magic.Menus.PopupMenu pm = new Crownwood.Magic.Menus.PopupMenu();
pm.MenuCommands.AddRange( new Crownwood.Magic.Menus.MenuCommand[]{ menu1,menu2 } );
pm.TrackPopup( rt.PointToScreen( new Point( e.X,e.Y ) ) );
}
}
