AutoCAD: Add shortcut keys/right-click

Autodesk. AutoCAD. applicationservices. application supports two contextmenu extensions: defaultcontextmenu and objectcontextmenu.

Defaultcontextmenu: no shortcut menu is selected in the current context.

Objectcontextmenu: select the shortcut menu for the specified type of entity in the current context. For example:

 

# Region Addcontextmenu
///   <Summary>
/// Right-click menu
///   </Summary>
Private   Void Addcontextmenu ()
{
Try
{
// Defaultcontextmenu
Contextmenuextension defaultcontextmenu =   New Contextmenuextension ();
Defaultcontextmenu. Title =   " Mydefaconcontextmenu " ;
Autodesk. AutoCAD. Windows. menuitem defaultcontextmenu_item1 =   New Autodesk. AutoCAD. Windows. menuitem ( " Mydefaconcontextmenu_item1 " , ARX. UI. Resources. resource1.taobao );
Defaultcontextmenu_item1.click + =   New Eventhandler (defaultcontextmenu_onclick );
Defaultcontextmenu. menuitems. Add (defaultcontextmenu_item1 );
Arxapp. adddefaconcontextmenuextension (defaultcontextmenu );

// Objectcontextmenu
Contextmenuextension objcontextmenu =   New Contextmenuextension ();
Objcontextmenu. Title =   " Myobjectcontextmenu " ;
Objcontextmenu. Popup + =   New Eventhandler (objcontextmenu_popup );

Autodesk. AutoCAD. Windows. menuitem objcontextmenu_item1 =   New Autodesk. AutoCAD. Windows. menuitem ( " Go to Baidu " , ARX. UI. Resources. resource1.baidu );
Objcontextmenu_item1.click + =   New Eventhandler (objcontextmenu_item1_click );
Objcontextmenu. menuitems. Add (objcontextmenu_item1 );

Autodesk. AutoCAD. Windows. menuitem objcontextmenu_item2 =   New Autodesk. AutoCAD. Windows. menuitem ( " Go to Google " , ARX. UI. Resources. resource1.google );
Objcontextmenu_item2.click + =   New Eventhandler (objcontextmenu_item2_click );
Objcontextmenu. menuitems. Add (objcontextmenu_item2 );

Arxapp. addobjectcontextmenuextension (rxobject. getclass ( Typeof (Polyline), objcontextmenu );
}
Catch (System. Exception exc)
{
Writeline ( String . Format ( " \ N contextmenu error: {0} " , Exc. Message ));
}
}

Void Objcontextmenu_popup ( Object Sender, eventargs E)
{
Using (Documentlock doclock = Arxapp. documentmanager. mdiactivedocument. lockdocument ())
{
Document Doc = Application. documentmanager. mdiactivedocument;
Database DB = Doc. database;
Editor ed = Doc. Editor;
Bool Visible =   True ;

// If that is multiple selection, disabled the menu item.
Promptselectionresult selectionres = Ed. selectimplied ();
If (Selectionres. Status = Promptstatus. OK)
{
Objectid [] objids = Selectionres. value. getobjectids ();
If (Objids ! =   Null   && Objids. Length >   1 )
{
Visible =   False ;
}
}

Contextmenuextension objcontextmenu = Sender As Contextmenuextension;
If (Objcontextmenu ! =   Null )
{
Foreach (Menuitem item In Objcontextmenu. menuitems)
{
Item. Enabled = Visible;
}
}
}
}

Private   Void Defaultcontextmenu_onclick ( Object Sender, eventargs E)
{
Using (Documentlock doclock = Arxapp. documentmanager. mdiactivedocument. lockdocument ())
{
Arxapp. showalertdialog ( " Defaultcontextmenu_onclick " );
}
}

Void Objcontextmenu_item1_click ( Object Sender, eventargs E)
{
Using (Documentlock doclock = Arxapp. documentmanager. mdiactivedocument. lockdocument ())
{
System. Diagnostics. process. Start ( " Iexplore. exe " , " Http://www.baidu.com " );
}
}

Void Objcontextmenu_item2_click ( Object Sender, eventargs E)
{
Using (Documentlock doclock = Arxapp. documentmanager. mdiactivedocument. lockdocument ())
{
System. Diagnostics. process. Start ( " Iexplore. exe " , " Http://www.google.com " );
}
}

# Endregion

You can perform some logic processing in the objcontextmenu_popup event.
