如何关闭一个IWpfTextView基于条件从IWpfTextViewCreationListener - VsText
本文关键字:条件 IWpfTextViewCreationListener VsText 于条件 IWpfTextView 何关闭 一个 | 更新日期: 2023-09-27 18:06:33
我有一个类监听IWpfTextViewCreationListener
using System.ComponentModel.Composition;
using Microsoft.VisualStudio;
using Microsoft.VisualStudio.Editor;
using Microsoft.VisualStudio.Shell;
using Microsoft.VisualStudio.Text.Editor;
using Microsoft.VisualStudio.TextManager.Interop;
using Microsoft.VisualStudio.Utilities;
using Microsoft.VisualStudio.OLE.Interop;
namespace GoToSequence
{
[Export(typeof(IVsTextViewCreationListener))]
[ContentType("Code")]
[TextViewRole(PredefinedTextViewRoles.Editable)]
internal class GoToSequenceEditorCreationListener : IVsTextViewCreationListener
{
[Import(typeof(IVsEditorAdaptersFactoryService))]
internal IVsEditorAdaptersFactoryService editorFactory = null;
public void VsTextViewCreated(IVsTextView textViewAdapter)
{
IWpfTextView textView = editorFactory.GetWpfTextView(textViewAdapter);
if (textView == null)
return;
AddCommandFilter(textViewAdapter, new GoToSequenceCommandHandler(textView, textViewAdapter));
}
void AddCommandFilter(IVsTextView viewAdapter, GoToSequenceCommandHandler commandFilter)
{
if (commandFilter.m_added == false)
{
//get the view adapter from the editor factory
IOleCommandTarget next;
int hr = viewAdapter.AddCommandFilter(commandFilter, out next);
if (hr == VSConstants.S_OK)
{
commandFilter.m_added = true;
//you'll need the next target for Exec and QueryStatus
if (next != null)
commandFilter.m_nextTarget = next;
}
}
}
}
}
在函数- VsTextViewCreated中,基于一定的条件,我想关闭textview。
If (condition == null)
IWpfTextView.Close()
然而,在这样做之后,我得到以下错误
系统。ObjectDisposedException was unhandled消息:一个未处理的类型'System '的异常。ObjectDisposedException'发生在Microsoft.VisualStudio.Platform.VSEditor.dll无法访问已处置的对象。
我也试过
if(condition == null)
IVsTextView.CloseView()
但这也没有帮助。什么可能是正确的方式来关闭编程的textview ?
好的…我能够解决以上问题…
var dte2 = (EnvDTE80.DTE2)Microsoft.VisualStudio.Shell.Package.GetGlobalService(typeof(Microsoft.VisualStudio.Shell.Interop.SDTE));
Microsoft.VisualStudio.OLE.Interop.IServiceProvider sp = (Microsoft.VisualStudio.OLE.Interop.IServiceProvider)dte2;
Microsoft.VisualStudio.Shell.ServiceProvider serviceProvider = new Microsoft.VisualStudio.Shell.ServiceProvider(sp);
Microsoft.VisualStudio.Shell.Interop.IVsUIHierarchy uiHierarchy;
uint itemID;
Microsoft.VisualStudio.Shell.Interop.IVsWindowFrame windowFrame;
Microsoft.VisualStudio.Shell.VsShellUtilities.IsDocumentOpen(serviceProvider, _iTextDocument.FilePath, Guid.Empty, out uiHierarchy, out itemID, out windowFrame);
windowFrame.CloseFrame((uint)__FRAMECLOSE.FRAMECLOSE_NoSave);
但是,我仍然想知道为什么不IWpfTextView.Close()或IVSTextView.CloseView()不工作…
