Rust Programming By Example

Saving a playlist

We'll start by adding a button to save the playlist. First, we add a field in the MusicToolbar structure for the button:

pub struct MusicToolbar {
    open_button: ToolButton,
    next_button: ToolButton,
    play_button: ToolButton,
    pub play_image: Image,
    previous_button: ToolButton,
    quit_button: ToolButton,
    remove_button: ToolButton,
    save_button: ToolButton,
    stop_button: ToolButton,
    toolbar: Toolbar,
}

And in the constructor, we'll create this button:

impl MusicToolbar {
    pub fn new() -> Self {
        let toolbar = Toolbar::new();

        let (open_button, _) = new_tool_button("document-open");
        toolbar.add(&open_button);

        let (save_button, _) = new_tool_button("document-save");
        toolbar.add(&save_button);

        toolbar.add(&SeparatorToolItem::new());

        // ...
