Solved it myself. I copied much of the AddPanel() function to my package and I can add what I want to the panel. I used the wxLuaEditor/wxLua control demo Lua application as a guide. Great framework.

I'm struggling to see how I can add other items to the panel though - I'd like a couple of panels, a button and a text input. Is there another "AddPanel" api that allows a sizer type container and other widgets to be added?

Should be possible, but I recommend using ide:AddPanel method; everything in the src/package.lua is a public API and is much less likely to change than using other (internal) functions/methods in ZBS. You can use ide:AddPanel(tagCtrl, "tagpanel", "Tag") to add your control a a panel. > I didn’t see any mention of adding a new window so I attempted to > duplicate all > occurrences of the Watch pane by duplicating existing > “Watch” related items, > e.g. watchCtrl->tagCtrl, > ID_ADDWATCH->ID_ADDTAG, > I don’t understand why wx.wxEVT_COMMAND_MENU_SELECTED is no longer valid. The reason you are getting this error is that you probably didn't register ID_ADDTAG, ID_EDITTAG and other IDs. You need to create them using "ID_ADDTAG = ID('mytagplugin.addtag')" code; the string you give to ID() has to be unique, so it's recommended for it to include a plugin name as a prefix. I highly recommend to initially make any changes as a plugin. There is a variety of API calls that can be used from plugins with about 50 plugins already in the repository (https://github.com/pkulchenko/ZeroBranePackage) and I've integrated ZBS with several products using plugin API (and I can extend it if something is missing).
