Is your feature request related to a problem?

The left mouse button and right button click on the tray icon by default to display the menu. If you want to customize the left and right click and double click to achieve different functions, no relevant methods have been found.

Is it possible to construct a solution with the existing API?

System tray supports custom click events

Probably depends upon fyne-io/systray#23.
Though it also needs a use-case to fulfil a Fyne feature request, otherwise it could be confusing to users as some OS assume a popup from the icon on tap.

Also specifying a function for a double click would be great as Windows users expect the application to show when the tray icon is double-clicked in most cases.

If the expectation is to set up the app to show on double click for Windows maybe we should do that.
Different platforms have different expectations for these interactions so exposing the actual events may not be the best way to deliver a cross platform consistent experience.

I have a use case for exposing the click event/action:

I show some running status as menu items in tray menu. I want to be able to refresh the latest states when user click the systray icon.

I want to be able to refresh the latest states when user click the systray icon.

Why would you not refresh the display when the state changes, instead of requiring the user to interact to see its update?
