    flag: MenuFlag,
    cb: F
) -> i32

Add a menu item along with its callback. The characters “&”, “/”, “\”, and “_” (underscore) are treated as special characters in the label string. The “&” character specifies that the following character is an accelerator and will be underlined. The “\” character is used to escape the next character in the string. Labels starting with the “_” (underscore) character cause a divider to be placed after that menu item. Takes the menu item as a closure argument

    cb: F
) -> i32

Inserts a menu item at an index along with its callback. The characters “&”, “/”, “\”, and “_” (underscore) are treated as special characters in the label string. The “&” character specifies that the following character is an accelerator and will be underlined. The “\” character is used to escape the next character in the string. Labels starting with the “_” (underscore) character cause a divider to be placed after that menu item. Takes the menu item as a closure argument

    msg: T
) -> i32

Add a menu item along with an emit (sender and message). The characters “&”, “/”, “\”, and “_” (underscore) are treated as special characters in the label string.

Labels starting with the “_” (underscore) character cause a divider to be placed after that menu item.

fn insert_emit<T: 'static + Clone + Send + Sync>(
    &mut self,
