VSTO對象操作 二

四、如何定義菜單

Office.CommandBarPopup cmdbar = null; Office.CommandBarButton menuInsertGraphics; private void AddMenuBar() { try { Office.CommandBarPopup cmdBarControl = null; ///獲取當前word窗口的菜單 Office.CommandBar menubar =(Office.CommandBar)Application.CommandBars.ActiveMenuBar; int controlCount = menubar.Controls.Count; string menuCaption = "作業規程(&Z)"; // Add the menu. cmdBarControl = (Office.CommandBarPopup)menubar.Controls.Add(Office.MsoControlType.msoControlPopup, missing, missing, controlCount, true); if (cmdBarControl != null) { cmdBarControl.Caption = menuCaption; cmdBarControl.Tag = menuTag; // 添加章節設計按鈕 menuCapterBtn = (Office.CommandBarButton)cmdBarControl.Controls.Add( Office.MsoControlType.msoControlButton, missing, missing, missing, true); menuCapterBtn.Caption = "章節設計(&C)"; menuCapterBtn.Tag = "menuCapter"; menuCapterBtn.FaceId = 43; menuCapterBtn.Click += new Microsoft.Office.Core._CommandBarButtonEvents_ClickEventHandler(menuCapterBtn_Click); // 添加按鈕 // 圖形 cmdbar = (Office.CommandBarPopup)cmdBarControl.Controls.Add( Office.MsoControlType.msoControlPopup, missing, missing, missing, true); cmdbar.Tag = "menuGraphics"; cmdbar.Caption = "插入圖形"; //圖形處理工具插 menuGraphicsBtn = (Office.CommandBarButton)cmdbar.Controls.Add( Office.MsoControlType.msoControlButton, missing, missing, missing, true); menuGraphicsBtn.Caption = "從圖形處理工具(&G)"; menuGraphicsBtn.Tag = "menuGraphics"; menuGraphicsBtn.FaceId = 53; menuGraphicsBtn.Enabled = false; menuGraphicsBtn.Click += new Microsoft.Office.Core._CommandBarButtonEvents_ClickEventHandler(menuGraphicsBtn_Click); } } catch (Exception e) { MessageBox.Show(e.Message); } }

 

如上述代碼所示，向Word菜單中，增加自定義項。一共分下列幾步：

l         獲取當前文檔的menu

l         將自定義的Office.CommandBarPopup插入到當前菜單

l         將自定義的Office.CommandBarButton 插入到自定義菜單項中

l         如果需要定義popu菜單，先定義二級CommandBarPopup，並將它插入自定義菜單項

並，爲其添加子CommandBarButton

l         注意：無法自定義按鈕的圖標。其圖標是通過FaceId來實現的(詳細參見《officeIco》)

l         注意：button的tag不要重複

l         注意：同時爲button指定響應事件

l         注意：cmdBarControl.Tag可以作爲自定義菜單是否存在的依據。所以很重要

五、如何設置工具欄

//當前toolbar Office.CommandBar commandToolbar; //章節結構 Office.CommandBarButton tlCapterBtn; //添加工具欄 private void AddToolBar() { try { commandToolbar = this.Application.CommandBars["ZygcToolBar"]; } catch { } if (commandToolbar == null) { commandToolbar = this.Application.CommandBars.Add("ZygcToolBar", Office.MsoBarPosition.msoBarTop, missing, true); } commandToolbar.Visible = true; //章節結構 tlCapterBtn = (Office.CommandBarButton)commandToolbar.Controls.Add(Office.MsoControlType.msoControlButton, missing, missing, missing, missing); tlCapterBtn.Style = Office.MsoButtonStyle.msoButtonIconAndCaption; tlCapterBtn.Tag = "toolCapter"; tlCapterBtn.FaceId = 43; tlCapterBtn.Caption = "章節結構"; tlCapterBtn.Visible = true; tlCapterBtn.Click += new _CommandBarButtonEvents_ClickEventHandler(menuCapterBtn_Click); //插入公式 }

如上述所示：

l         根據commandtoolbar的tag屬性，判斷自定義toolbar是否存在

l         如果沒有就創建

l         將自定義button添加進去

l         同菜單一樣，ico只能通過FaceId來確定

l         需要同時指定響應事件

六、如何設置自己的popuMenu

Office.CommandBar menuFormular; //公式菜單 Office.CommandBarButton addParment;//添加參數 Office.CommandBarButton repariFormular;//解析公式 /// <summary> /// 生成pop菜單 /// </summary> private void RepairMenu() { //聲明popu菜單 menuFormular = ThisApplication.CommandBars.Add("MenuFormular", Office.MsoBarPosition.msoBarPopup, missing, true); //添加參數 addParment = (Office.CommandBarButton)menuFormular.Controls.Add(1, missing, missing, missing, missing); addParment.Style = Office.MsoButtonStyle.msoButtonCaption; addParment.Caption = "添加參數"; addParment.FaceId = 137; addParment.Click += new _CommandBarButtonEvents_ClickEventHandler(addParment_Click); //公式解析 repariFormular = (Office.CommandBarButton)menuFormular.Controls.Add(1, missing, missing, missing, missing); repariFormular.Style = Office.MsoButtonStyle.msoButtonCaption; repariFormular.Caption = "公式解析"; repariFormular.FaceId = 23; repariFormular.Click += new _CommandBarButtonEvents_ClickEventHandler(repariFormular_Click); }

如上例所示：

l         需要操作的是applcation級的CommandBars對象

l         需要指定必須的參數爲名字、式樣Office.MsoBarPosition.msoBarPopup

l         菜單項的ICO也是要通過FaceId來獲取

l         添加自定義popu菜單的子項時，就同時爲其指定響應事件
