You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: connect_header_buttons.rs
    path of file: ./repos/czkawka/czkawka_gui/src/connect_things
    
    the code of the file until where you have to start completion: use gtk4::prelude::*;

use crate::gui_structs::gui_data::GuiData;

pub fn connect_button_about(gui_data: &GuiD
    
pub fn connect_button_about(gui_data: &GuiData) {
    let about_dialog = gui_data.about.about_dialog.clone();
    let button_app_info = gui_data.header.button_app_info.clone();
    button_app_info.connect_clicked(move |_| {
        about_dialog.show();

        // Prevent from deleting dialog after close
        about_dialog.connect_close_request(|dialog| {
            dialog.hide();
            glib::Propagation::Stop
        });
    });
}
