On click tray event ? about systray

[LukePulverenti]

Exposing a double click event would also be nice.

We aren't able to pull away to implement this right away unfortunately but PRs are most welcome!!!

Same question...

[biter777]

Please, implement the "On click tray event" (WM_RBUTTONUP / WM_LBUTTONUP).
Maybe as OnIconTrayClickHandler()...

Please! :)

@myleshorton point me in the right direction and I can tackle this

I started down this road for windows, trying to create a minimal change to handle right-click, left-click and left-double-click, but ran into the following questions:

1. Should it use a channel or set of channels (like existing menu click handlers) or should it be "OnIconTray[Left|Right][Double]ClickHandler" as suggested by @biter777
2. Distinguishing single click from double click requires "debouncing" (when you receive a click, wait a bit to see if it is really going to be the first click in a double click), as per https://devblogs.microsoft.com/oldnewthing/20041015-00/?p=37553

So for the moment my modifications fit my needs: distinguishing RightClick from LeftDoubleClick. But obviously that's not completely general:

systray_windows.go function wndProc line ~ 284:

		switch lParam {
		case WM_RBUTTONUP://, WM_LBUTTONUP:
			t.showMenu()
		case WM_LBUTTONUP:
			//XXX: need to debounce so this doesn't fire on a double click
			//start timer, wait, cancel timer if double click arrives, send msg on timer end
			//and also ignore subsequent click event after double click
			//systrayClicked()
		case WM_LBUTTONDBLCLK://WM_LBUTTONUP:
			//XXX: cancel timer here, tell single slick to eat next click
			systrayDoubleClicked() 
		}
