Yes, absolutely! And, it allows one to have more fiddly widgets in those system tray menus then, too (like sliders, calendars, switches, etc.).[...] I have two questions: 1. Is there some risk that trayer will stop being able to handle applets from things like network-manager ? If so what should I replace it with ?
Not in the foreseeable future, I guess (except from trayer being GTK-2).The fancy widgets (sliders, etc.) for now appear in _system_ indicators, only. They are special indicators in MATE, XFCE (optionally), possibly Budgie (optionally), that have a special rendering and don't use the StatusNotifierItem implementation. (And they don't work, yet, on Debian, only on Ubuntu, because they require some Ubuntu'ish GTK-3 patch).
The AppIndicator based applications only use menu items (widgets) that have been used in Xembed based systray menus, so far.
I also have an (symbiosisware, so as yet unreleased) program which uses tk-tktray (package `tktray'), and embeds an X window belonging to a different executable.
2. Is there some risk that tktray will not work with the
answer to (1) ? If so what should I replace it with ?
tk-tktray is an API for Xembed'ding a systray icon. This will continue to work, as long as a desktop env provides Xembed support. However, I wouldn't code new projects based on tk-tkray.
Answers to 1 should not suppose that I want to change my window manager or adopt a full-on `desktop environment' or a `panel' (unless
The window manager is +/- totally unrelated to the topic.
perhaps the panel can be made to be as small as its contents). My window manager is vtwm.
Some weeks ago, I uploaded the vala-panel package to unstable. It supports AppIndicators and Xembed based applications alike. It could well need some more testers and feedback. However, it is a promising project esp. for people that don't want to use a specific desktop env but rather assemble their own working environment.
Answers to 2 should ideally suppose that I want to continue to use XID-based window embedding to make an applet which contains the window from a separate X client.
I am not sure, I am fully getting the application design, you have in mind here. Do you mean X-embedding (this is about icons and systray and the icons have menus and submenus) or reparenting? With X11 reparenting you can reparent X11 application 1 into X11 application 2. (xterm has it even as cmdline option).
I note that neither trayer nor tktray seem to involve any of the libraries being discussed in this thread. Is that because an `indicator' is not the same as an `applet', or is it due to churn, or something else ?
It is because AppIndicator does not do X-embedding at all. And for X-embedding, you merely new some libX11 calls. AppIndicator / SNI is about an application (written in GTK, Qt, what-not) sending its menu tree and systray icon over DBus and on the other end a desktop env applet (renderer) that pumps this menu structure into the panel (your elsewhere appropriate).
I you have more question, please ask. Thanks for the discussion!
