[QUESTION] How to know which action are being trigger in EventHandler

[qng95]

Hello pals,

I'm trying to create a tray icon following this example https://github.com/lxn/walk/tree/master/examples/notifyicon

The menu items inside could be dynamically created on the fly base on data that it queries from the server. Then actions are created base on that data, and event handlers for those actions should result in different method calls depends on the text value of that action.

items = GetItemsFromAPI()
for _, item := range items {
    action := walk.NewAction()
    action.SetText(item)
    action.Triggered().Attach(func() {
        // this event handler doesn't known any information about it owner action. So it should not determine which method it should call
    })
    provisionerMenu.Actions().Add(action)
}

Is there a way to let's EventHandler know about its owner Actions?

Thank you very much 👍

Cheers

Hello Quan,

Can you be a bit more concrete?

How the method call looks like?

I believe there is a way, but I am unable to crack a simple example right now.

Hello again,

Can this simple example help you?

You may create a closure which capture some context:

packagemain import"fmt" funcCreateGreeter(name string) func() { returnfunc() {         fmt.Println("Hello,", name)     } } var( greetQuanfunc() greetLubosfunc() ) funcmain() { greetQuan= CreateGreeter("Quan") greetLubos= CreateGreeter("Lubos") greetQuan() greetLubos() } Dňa 6. 10. 2021 o 11:55 Quan Hong Nguyen napísal(a):
