fn add_empty_label( &mut self, breadcrumb_bottom: i32, thickness: i32, big_height: i32, )

fn add_file_entries( &mut self, start_idx: usize, end_idx: usize, breadcrumb_bottom: i32, thickness: i32, big_height: i32, big_thickness: i32, small_thickness: i32, max_lines: usize, context: &mut Context, )

Adds file entry views to the FileChooser’s children for the current page.

Each file entry is represented using the FileEntry component, which displays the file or directory’s name, icon, and metadata (such as size and modification date). Between each entry, a separator is added using the Filler component to visually separate the entries.

Components used to build each file entry:

• FileEntry: Displays the file or directory entry, including icon, name, and metadata.
• Filler: Used as a separator between file entries for visual clarity.

Arguments

• start_idx - The starting index of the entries to display.
• end_idx - The ending index (exclusive) of the entries to display.
• breadcrumb_bottom - The y-coordinate below the breadcrumb bar.
• thickness - The thickness of the separator lines.
• big_height - The height of each file entry row.
• big_thickness - The thickness of the separator between entries.
• small_thickness - The thickness of the separator at the end of the list.
• max_lines - The maximum number of entries to display per page.
• context

fn update_entries_list(&mut self, rq: &mut RenderQueue, context: &mut Context)

fn create_bottom_bar(&mut self)

fn select_item(&mut self, path: PathBuf, bus: &mut Bus)

Selects the given item if it matches the selection mode. Sends FileChooserClosed event with the selected path to the bus.
