question:ITfLangBarItemMgr没有CreateItem方法
answer:对不起,我的错误。ITfLangBarItemMgr接口没有CreateItem方法。应该使用ITfLangBarItemMgrEx接口的CreateItem方法来创建语言栏项。您可以创建一个类实现ITfLangBarItemButton,并在创建语言栏项时将其传递给CreateItem方法,如下所示: ```csharp using System; using System.Runtime.InteropServices; using System.Windows.Forms; namespace LanguageBarDemo { public partial class Form1 : Form { [DllImport("Msctf.dll")] private static extern int TF_CreateLangBarMgr(out ITfLangBarMgr ppLangBarMgr); [ComVisible(true)] [ClassInterface(ClassInterfaceType.None)] public class ButtonItem : ITfLangBarItemButton { public void OnClick(TfLBIClick click, POINT pt, ref RECT prcArea, ITfContext pContext) { MessageBox.Show("Language bar button clicked!"); } public void InitMenu(ITfMenu pMenu) { } public void OnMenuSelect(int id) { } public void GetInfo(out TfLBINFO pInfo) { pInfo = new TfLBINFO(); pInfo.clsidService = typeof(LanguageBarDemo).GUID; pInfo.guidItem = Guid.NewGuid(); pInfo.dwStyle = (uint)(TfLbiStyle.TfLbiStyleBtnIntrusive | TfLbiStyle.TfLbiStyleBtnShowText); pInfo.ulSort = 0; pInfo.szDescription = "Language bar demo button"; } public void GetStatus(out TF_LBI_STATUS pdwStatus) { pdwStatus = 0; } public void Show(bool bShow) { } public void GetTooltipString(out string pbstrToolTip) { pbstrToolTip = "Click me"; } } private ITfThreadMgr threadMgr; private ITfLangBarMgr langBarMgr; private ITfLangBarItemMgrEx itemMgrEx; private ITfLangBarItemButton button; public Form1() { InitializeComponent(); // 初始化TextService InitializeTextService(); } private void InitializeTextService() { // 获取当前线程管理器 threadMgr = (ITfThreadMgr)new CtfThreadMgr(); threadMgr.Activate(); // 获取语言栏管理器和语言栏项管理器 TF_CreateLangBarMgr(out langBarMgr); langBarMgr.GetThreadLangBarItemMgr(out ITfLangBarItemMgr itemMgr); // 获取ITfLangBarItemMgrEx接口,如没有则退化到ITfLangBarItemMgr itemMgr.QueryInterface(typeof(ITfLangBarItemMgrEx).GUID, out var obj); itemMgrEx = obj as ITfLangBarItemMgrEx ?? itemMgr as ITfLangBarItemMgrEx; // 创建语言栏按钮项 itemMgrEx.CreateItem(typeof(ButtonItem), out var item); // 转到主线程设置控件并显示语言栏按钮 BeginInvoke(new Action(() => { // 设置控件 button = (ITfLangBarItemButton)item; button.GetInfo(out var info); button.SetText(info.szDescription); // 添加语言栏按钮到语言栏 itemMgr.AddItem(button, item); langBarMgr.AdviseItemSink(button, new ButtonSink(), out _); })); } // 语言栏按钮事件接收器 private class ButtonSink : ITfLangBarItemSink { public void OnUpdate(TfLBIClick click, POINT pt, ref RECT prcArea) { // 暂不处理 } } } } ``` 在上面的示例中,我们实现了一个ButtonItem类,该类实现了ITfLangBarItemButton接口,负责处理语言栏按钮的点击事件。在初始化TextService时,我们获取了ITfLangBarItemMgrEx接口,并使用CreateItem方法将ButtonItem添加到语言栏中。 在CreateItem方法的参数中,第一个参数是我们要创建的语言栏项类的COM类ID。如果我们想要更改按钮的样式和文本,可以在GetInfo方法中设置相关属性。 请注意,在这个例子中,我们只在点击按钮时弹出了一个简单的消息框。实际操作中,您可能需要执行更复杂的操作来处理语言栏按钮的点击事件。
question:使用 ITfLangBarItemMgr的 AddItem方法可以实现吗
answer:是的,您也可以使用ITfLangBarItemMgr的AddItem方法实现语言栏按钮。只需要实现ITfLangBarItemButton接口,并调用AddItem方法将其添加到语言栏中即可。以下是一个简单的示例代码: ```csharp using System; using System.Runtime.InteropServices; using System.Windows.Forms; namespace LanguageBarDemo { public partial class Form1 : Form { [DllImport("Msctf.dll")] private static extern int TF_CreateLangBarMgr(out ITfLangBarMgr ppLangBarMgr); private ITfThreadMgr threadMgr; private ITfLangBarMgr langBarMgr; private ITfLangBarItemMgr itemMgr; private ITfLangBarItemButton button; public Form1() { InitializeComponent(); // 初始化TextService InitializeTextService(); } private void InitializeTextService() { // 获取当前线程管理器 threadMgr = (ITfThreadMgr)new CtfThreadMgr(); threadMgr.Activate(); // 获取语言栏管理器和语言栏项管理器 TF_CreateLangBarMgr(out langBarMgr); langBarMgr.GetThreadLangBarItemMgr(out itemMgr); // 创建语言栏按钮项 itemMgr.CreateItem(TfLbiStyle.TfLbiStyleBtnIntrusive, new ButtonCallback(), out var item); // 设置控件 button = (ITfLangBarItemButton)item; button.SetText("Language Bar Button"); // 添加语言栏按钮到语言栏 itemMgr.AddItem(button, item); } // 语言栏按钮回调 private class ButtonCallback : ITfLangBarItemButton { public void OnClick(TfLBIClick click, POINT pt, ref RECT prcArea, ITfContext pContext) { MessageBox.Show("Button clicked!"); } // 下面的方法都是ITfLangBarItem的默认实现,暂不做处理 public void GetInfo(out TfLBINFO pInfo) { pInfo = new TfLBINFO() { clsidService = new Guid(), dwStyle = TfLbiStyle.TfLbiStyleBtnIntrusive | TfLbiStyle.TfLbiStyleBtnShowText, guidItem = new Guid(), szDescription = "Button" }; } public void GetStatus(out TF_LBI_STATUS pdwStatus) { pdwStatus = 0; } public void Show(bool bShow) { } public void GetTooltipString(out string pbstrToolTip) { pbstrToolTip = "Click me!"; } public void InitMenu(ITfMenu pMenu) { } public void OnMenuSelect(int id) { } } } } ``` 在上面的示例中,我们使用了ITfLangBarItemMgr的CreateItem方法来创建语言栏按钮项,并使用ITfLangBarItemMgr的AddItem方法将其添加到语言栏中。在创建语言栏按钮项时,我们提供了一个实现了ITfLangBarItemButton接口的ButtonCallback对象,用于处理按钮的点击事件。需要注意的是,ITfLangBarItemButton接口的参数中的prcArea是一个ref类型的参数,需要用ref按引用传递。 在代码中,我们调用了SetText方法来设置按钮的文本,如果您还想设置其他属性,可以通过实现ITfLangBarItemButton接口提供自定义的实现来实现。
