Add system tray support

[jiajunhuang]

sometimes I need the app to minimize, and stay in the system tray, will fyne support system tray?

[andydotxyz]

Yes it will, at some point. Probably not in 1.1 or 1.2 but I would like to see it added soon after.

I use systray to achieve this function, first transition

i need to create app with only system tray. But systray package cant create multi-level menu

[andydotxyz]

Currently we don't have sub-menu support either.
We should add it soon, though I don't think it has a ticket so I will add one now.

Systray will come :)

When i use systray and fyne. It works perfectly fine on windows OS, but fails on Mac OS. Is there a workaround to this problem? it seems its caused by runtime.LockOSThread() used by fyne and systray in the main.

macOS requires that code manipulating graphical elements run on the main thread. Do these things must run within the main() goroutine. Future versions of Fyne will be enforcing this to ensure cross platform consistency.

Submenu support is now in so it seeme likely that we could include systray in 2.0 late this year

[izturn]

any progress ?

[andydotxyz]

No, sorry. 2.0 is due this month but we are really up against it and late last year really did not exactly go according to plan (as for many people).
