abstract member ShowContextMenu : int * Guid * Microsoft.VisualStudio.OLE.Interop.IOleCommandTarget * int * int -> unit
override this.ShowContextMenu : int * Guid * Microsoft.VisualStudio.OLE.Interop.IOleCommandTarget * int * int -> unit
Public Overridable Sub ShowContextMenu (menuId As Integer, groupGuid As Guid, target As IOleCommandTarget, x As Integer, y As Integer)

Parameters

menuId
Int32

[in] The ID of the menu to show.

groupGuid
Guid

[in] The GUID of the menu group from which the menu ID is taken.

target
IOleCommandTarget

[in] The IOleCommandTarget object that is to handle the commands in the context menu.

x
Int32

The x value of the point used in ShowContextMenu(UInt32, Guid, Int32, POINTS[], IOleCommandTarget).

y
Int32

The y value of the point used in ShowContextMenu(UInt32, Guid, Int32, POINTS[], IOleCommandTarget).

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;  
        }  
    }  
}

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.
