Remarks
This method is called to handle a context menu in the current view. This provides an opportunity to display your own context menu or modify the existing menu and show it.
The base method is called with a menuID of IDM_VS_CTXT_CODEWIN, a groupGuid of guidSHLMainMenu, and a target of the IOleCommandTarget interface implemented on the ViewFilter class. The base method determines if macros are not being recorded and then shows the context menu.
Examples
Here is how the base ViewFilter class implements this method.
using System;
using Microsoft.VisualStudio.OLE.Interop;
using Microsoft.VisualStudio.Shell;
namespace Microsoft.VisualStudio.Package
{
[CLSCompliant(false)]
[System.Runtime.InteropServices.ComVisible(true)]
public class ViewFilter :
IVsTextViewFilter,
IVsTextViewEvents,
IOleCommandTarget,
IDisposable
{
public virtual void ShowContextMenu(int menuId,
Guid groupGuid,
IOleCommandTarget target)
{
IVsUIShell uiShell = this.service.GetService(typeof(SVsUIShell)) as IVsUIShell;
// disable context menu while recording macros.
if (uiShell != null && !this.service.IsMacroRecordingOn())
{
System.Drawing.Point pt = System.Windows.Forms.Cursor.Position;
POINTS[] pnts = new POINTS[1];
pnts[0].x = (short)pt.X;
pnts[0].y = (short)pt.Y;
int hr = uiShell.ShowContextMenu(0, ref groupGuid, menuId, pnts, target);
if (hr < 0)
{
Debug.Assert(false, "uiShell.ShowContextMenu returned " + hr);
}
}
uiShell = null;
}
}
}
