Attach additional Menu Items from your Addin

You can use the OnWindowLoaded method i to attach additional menu items to the menu.

For example, the Gist Integration Addin adds two new menu items to - Save as Gist and Open from Gist - from to the default File menu using the following code:

// create and add custom menu item
var mitemOpen = new MenuItem()
{
    Header = "Open from Gist",
    Name = "ButtonOpenFromGist"
};
mitemOpen.Click += (s, a) => OnExecuteLoadGist();            
if (!AddMenuItem(mitemOpen, menuItemNameForInsertionAfter: "ButtonOpenFromHtml", mode: 0))
    mmApp.Log("Unable to add custom menu item in Paste Code As Gist Addin: " + mitemOpen.Name);

var mitemSave = new MenuItem()
{
    Header = "Save to Gist",
    Name = "ButtonSaveToGist"
};
mitemSave.Click += (s, a) => OnExecuteSaveGist();
if (!AddMenuItem(mitemSave, menuItemNameForInsertionAfter: "ButtonGeneratePdf", mode: 0))
    mmApp.Log("Unable to add custom menu item in Paste Code As Gist Addin: " + mitemSave.Name);

The key method is AddMenuItem() which allows you to specify the control name or caption of an existing menu item to insert a new menu item before (mode 1) or after (0). You can also replace existing menu items (2).
