利用OutlookBar命名空间

程序中调用:
1.
OutlookBar outlookBar=new OutlookBar();
int i=0;//记录面板总索引
IconPanel currentpanel;//记录当前的面板；
2.
InitializeComponent();
// TODO: 在 InitializeComponent 调用后添加任何构造函数代码
//创建outlookbar
outlookBar.Location=new Point(0, 0);
outlookBar.Size=new Size(120, this.ClientSize.Height);
outlookBar.BorderStyle=BorderStyle.FixedSingle;
Controls.Add(outlookBar);
outlookBar.Initialize();
//创建类别面板
IconPanel iconPanel1=new IconPanel();
IconPanel iconPanel2=new IconPanel();
IconPanel iconPanel3=new IconPanel();
outlookBar.AddBand("Outlook Shortcuts", iconPanel1);
outlookBar.AddBand("My Shortcuts", iconPanel2);
outlookBar.AddBand("Other Shortcuts", iconPanel3);
//创建类面板下的子项目
iconPanel1.AddIcon("Outlook Today", Image.FromFile("img1.ico"), new EventHandler(PanelEvent));
iconPanel1.AddIcon("Calendar", Image.FromFile("img2.ico"), new EventHandler(PanelEvent));
iconPanel1.AddIcon("Contacts", Image.FromFile("img3.ico"), new EventHandler(PanelEvent));
iconPanel1.AddIcon("Tasks", Image.FromFile("img4.ico"), new EventHandler(PanelEvent));
//选择面板
outlookBar.SelectBand(0);
3.
//相应子项目的事件
public void PanelEvent(object sender, EventArgs e)
{
Control ctrl=(Control)sender;
PanelIcon panelIcon=ctrl.Tag as PanelIcon;
MessageBox.Show("#"+panelIcon.Index.ToString(), "Panel Event");
}
4.
private void button1_Click(object sender, System.EventArgs e)
{
string panelname="新增组";
WindowsApplication1.Form2 f2 =new WindowsApplication1.Form2();
DialogResult d=f2.ShowDialog(this);
if(d==DialogResult.OK)
{
panelname=f2.textBox1.Text;
}
//新增组面板
IconPanel panel=new IconPanel();
outlookBar.AddBand(panelname, panel);
currentpanel=panel;
outlookBar.SelectBand(3);
}
5.
private void button2_Click(object sender, System.EventArgs e)
{
//在当前组新增项目
currentpanel.AddIcon("新增项目",Image.FromFile("img1.ico"),new EventHandler(PanelEvent));
}
6.
private void button3_Click(object sender, System.EventArgs e)
{
//得到被选的面板索引
int index=outlookBar.SelectedBand;
outlookBar.SelectBand(index);
}
