Menu improvements

[leaanthony]

This PR cointains:

• application.DefaultApplicationMenu() *Menu which will return the default application menu for the current platform
• Menu.FindByLabel(label string) to find a menu item by its label. Returns nil if not found.
• Menu.ItemAt(index int) for retrieving menu items by index. Returns nil if out of bounds.
• Menu.RemoveMenuItem(*MenuItem) for removing a menu item.
• MenuItem.RemoveAccelerator() for removing the accelerator.
• MenuItem.GetAccelerator() string for getting a menu item's accelerator.
• MenuItem.GetSubmenu() *Menu for getting a submenu (nil if not a submenu item).

Menu.Update() needs calling after any changes.

A small change that I had to make to fix an error when running wails3 dev

This pr does give you the ability to get the default menu, but I am not sure how you would update it besides adding.

If I wanted to remove Toggle Fullscreen, how would I go about that? I need to remove the item, but it seems like there's no direct access to the items array.

I tried setting it hidden, but that didn't work

menu := application.DefaultApplicationMenu()
viewMenu := menu.FindByLabel("Toggle Full Screen")
if viewMenu != nil {
    viewMenu.SetHidden(true)
}

This doesn't seem to work on the defaultMenu. 👇 is not working for me

	menu := application.DefaultApplicationMenu()
	menuItem := menu.FindByLabel("Toggle Fullscreen")
	if menuItem != nil {
		menu.RemoveMenuItem(menuItem)
	}

	app.SetMenu(menu)

Menu.Update() needs calling after any changes.

Try that ☝️

[Etesam913]

Still does not work

        menu := application.DefaultApplicationMenu()
	menuItem := menu.FindByLabel("Toggle Fullscreen")
	if menuItem != nil {
		menu.RemoveMenuItem(menuItem)
	}
	menu.Update()
	app.SetMenu(menu)

Just pushed a fix. However, you'll need to search for the label "Toggle Full Screen" to find the right one.

This works for me now, thanks

I had to do this:

menu := application.DefaultApplicationMenu()
menuItem := menu.FindByLabel("Toggle Full Screen")
if menuItem != nil {
    menu.RemoveMenuItem(menuItem)
}
app.SetMenu(menu)
menu.Update()

Is there a way to give access to the submenu of a menu item if it has one.

For example, if I want to add a menu item to the file menu, it doesn't seem possible.

Doing the below does not give me access to the Add function

Ideally, a GetSubmenu function can be exposed to the MenuItem that can either return the Menu or nil

There is an isSubmenu method, but I am not too sure if that can be used

This worked for my usecase!

Thanks
