SharpDevelop工作台的加载，布局，管理

 

工作台

工作台的加载，布局，管理 

命令模式：以Command作为对象的事件，实际上不过是统一(RUN)接口的事件而已，

new SdMenuCommand()

o = AddIn.CreateObject(Class);// class = "ISpiderMan.PoManage.RunPoManage"

IMenuCommand menuCommand = (IMenuCommand)o;

SdMenuCommand.menuCommand = menuCommand;

//=============================================================================================

CreateMainMenu();

=================================把主菜单显示在CommandBar上面==================================

CreateToolBars();

TopMenu.Items.AddRange(items);

this.commandBar.AddItem(item);

this.UpdateItems();

this.AddItems();

for (int i = 0; i < items.Count; i++)

{

 NativeMethods.TBBUTTON button = new NativeMethods.TBBUTTON();

 button.idCommand = i;

 NativeMethods.SendMessage(this.Handle, NativeMethods.TB_INSERTBUTTON, i, ref button);画button

}

DefaultWorkbench : Form, IWorkbench                 

1,从AddInTree中取得信息"/SharpDevelop/Workbench/MainMenu"生成MainMenu存入到容器中

TopMenu èCommandBar

CommandBar { CommandBarItemCollection{ ArrayList{ CommandBarItem []}}}

CommandBarItem[]中存放Menu实体(new SdMenuCommand()),è祥见：MenuItemCodon

2,从AddInTree中取得信息"/SharpDevelop/Workbench/ToolBar"生成ToolBar存入到容器中

ToolBars è CommandBar[]

CommandBar { CommandBarItemCollection{ ArrayList{ new SdMenuCommand()}

CommandBarItem[]中存放Menu实体(new SdMenuCommand())

3，把TopMenu, ToolBars中CommandBar存入CommandBarManager的CommandBarCollection中

CommandBarManager{CommandBarCollection{ArrayList{CommandBar}}}

 

4,从AddInTree中取得信息"/SharpDevelop/Workbench/Views"生成可隐藏的视图存入到容器中

PadContentCollection viewContentCollection       = new PadContentCollection();

PadContentCollection.Add(content);

public class PadCodon : ClassCodon

return AddIn.CreateObject(Class);

//Clase = "ISpiderMan.SharpDevelop.Services.DefaultProjectService"

Infragistics.Win.UltraWinListBar.UltraListBar ulbRentals = new UltraListBar();显示控件

 

CommandBarItem[] items = (CommandBarItem[])(AddInTreeSingleton.AddInTree.GetTreeNode(mainMenuPath).BuildChildItems(this)).ToArray(typeof(CommandBarItem));

BuildChildItems(this) 返回的是ArrayList,中装的是CommandBarItem封装的SdMenuCommand

 

public class ModuleBrowser : AbstractPadContent

{

RedrawContent()//处理显示控件

InitializeRentalsListBar();

public override Control Control

{           get           {                  return ulbRentals;          }        }

}

 

 

SdiWorkbenchLayout : IWorkbenchLayout          布局管理器

workbench.WorkbenchLayout = new SdiWorkbenchLayout();

DefaultWorkbench.layout

 

 

//将上一次使用的Workbench布局等信息重新载入,

            //return new WorkbenchMemento(element);

            w.SetMemento((IXmlConvertable)propertyService.GetProperty(workbenchMemento, new WorkbenchMemento()));

 

//刷新Workbench，根据插件树信息，打开启动时需要展现的Pad和Editor

              w.UpdatePadContents(null, null);

 

//

WorkbenchSingleton.CreateWorkspace();//UI布局创建默认工作台

public static void CreateWorkspace()

         {

              SetWbLayout();//UI布局

              OnWorkbenchCreated();

              workbench.RedrawAllComponents();//更新标题

         }

workbench.WorkbenchLayout = new SdiWorkbenchLayout();//通过属性初始化布局

 

         public void Attach(IWorkbench workbench)

{ dockPanel = new WeifenLuo.WinFormsUI.DockPanel();}//关键控件,可以隐藏，附着的Panel

一级菜单和工具条先加入到DefaultWorkbench的CommandBarManage中（相当与ToolBar）

((DefaultWorkbench)workbench).commandBarManager.CommandBars.Add(((DefaultWorkbench)workbench).TopMenu);

//主菜单

((DefaultWorkbench)workbench).commandBarManager.CommandBars.Add(toolBar);//CommandBarManage统一管理主菜单，工具条****SDMenuCommand怎么转换到CommandBarItem，一定要转吗？

DockContent newContent = CreateContent(content);//包装

                   newContent.Show(dockPanel);//挂到Panel控件

不管是菜单还是工具条单击都是先触发CommandBar

//========================================================================================

 

public class CommandBar : Control, IDisposable

{

{ this.PerformClick(this.items[index]);//工具条响应事件，有效

}

private bool PerformClick(CommandBarItem item)

{control.PerformClick(EventArgs.Empty);//工具条响应事件}}

 

CommandBar

{protected override void OnMouseDown(MouseEventArgs e)//菜单的响应事件,Control本身的Event封装

{if ((e.Button == MouseButtons.Left) && (e.Clicks == 1))

{int index = this.HitTest(point);//从单击相素点判断单击菜单项

this.TrackDropDown(index);//生成下拉菜单，index为单击菜单项在CommandBar上的位置}}

private void TrackDropDown(int index)

{this.contextMenu.Items.AddRange(menu.Items); // = menu.Items;生成下拉菜单}

}

 

 

//Menu菜单响应事件PerformClick(EventArgs e)

//===================================================================

private class MenuBarItem : MenuItem

{

this.item = item;//item为SdMenuCommand?

protected override void OnClick(EventArgs e)

{

     base.OnClick(e);

     CommandBarControl control = this.item as CommandBarControl; //实际上item为SdMenuCommand实际上item为SdMenuCommand封装

     if (control != null)

     {    control.PerformClick(EventArgs.Empty); //菜单单击响应事件,已确定 }

     }

//单击CommandBar重画MenuCommandBar

 

//=========================================================================================

class CommandBarControl : CommandBarItem{

internal void PerformClick(EventArgs e)

{        MessageBox.Show("工具条，菜单单击响应事件");

          this.OnClick(e);//this其实是SdMenuCommand，怎样触发Command.Run()

}}

public class SdMenuCommand : CommandBarButton, IStatusUpdate

     {

         {

              base.OnClick(e);

              if (menuCommand != null) {

                   //menuCommand.Run();//调用菜单的Run() Command模式的伟大

              }

         }

}

点击菜单CommandBar生成下拉菜单

private CommandBarItemCollection items = new CommandBarItemCollection();

CommandBarMenu menu = CommandBar.items[index] as CommandBarMenu;

public CommandBarItem this[int index]

         {

              get { return (CommandBarItem)items[index]; }

         }

private CommandBarContextMenu contextMenu = new CommandBarContextMenu();

this.contextMenu.Items.AddRange(menu.Items); // = menu.Items;生成下拉菜单,加入到CommandBarContextMenu

protected override void OnPopup(EventArgs e)// CommandBarContextMenu响应事件

         {

              base.OnPopup(e);

              this.UpdateItems();//转换为可单击的菜单

         }

//生成下拉菜单

                   this.MenuItems.Add(new MenuBarItem(item, imageSize, this.font, this.mnemonics));

// MenuItems为系统Menu提供菜单集合, new MenuBarItem提供单击响应事件，触发CommandBar.Run()

this.commandBar.AddItem(item);

this.UpdateItems();//

private void UpdateItems()

        {

            if (this.IsHandleCreated)//成立

            {

                this.BeginUpdate();

                this.RemoveItems();

                this.AddItems();//

                this.EndUpdate();

            }

        }

this.contextMenu.Show(this, position);//在CommandBar上显示CommandBarContextMenu
