wFrame1.Frame_BarControl   =   outlookBar;
wFrame1.Frame_Form   =   new   Form1(wFrame1);       //开始右边默认调用Form1,我想点击左边的菜单调用其他的Form
}


#region   OutlookBar   Click   stuff

///   <summary>

private   void   wOutlookBar_ItemClicked(object   sender,   LumiSoft.UI.Controls.WOutlookBar.ItemClicked_EventArgs   e)
{
MessageBox.Show(e.Item.Caption);
}

#region   function   InitBar

private   void   InitBar()
{
outlookBar   =   new   LumiSoft.UI.Controls.WOutlookBar.WOutlookBar();
outlookBar.ImageList   =   this.imageList1;
outlookBar.ItemClicked   +=   new   LumiSoft.UI.Controls.WOutlookBar.ItemClickedEventHandler(this.wOutlookBar_ItemClicked);

Item   it   =   null;
Bar   bar   =   null;
//Bar   a   =   outlookBar.Bars.Add( "ViewStyle ");
//a.Items.Add( "Set   ViewStyle ",0);

Bar   stuckingTest   =   outlookBar.Bars.Add( "Stucking   test ");
stuckingTest.Items.Add( "Can   stuck ",0);
stuckingTest.Items.Add( "Can   stuck ",0);

it   =   stuckingTest.Items.Add( "Can 't   stuck ",0);

stuckingTest.Items.Add( "Can 't   stuck ",0);
