Fields

state: Arc<Mutex<EditorState>>

theme: UiTheme

search_filter: String

flat: Vec<FlatAsset>

asset_dirs: Vec<String>

Every real directory under assets/ (forward-slash, relative), mirrored from EditorState::asset_dirs so empty / freshly-created folders show up in the tree even though the file-only VFS never lists them.

last_epoch: Option<u64>

Last EditorState::asset_epoch we rebuilt flat for; a mismatch drives the rescan (an in-place edit that doesn’t change the entry count used to be missed by the old (folder, len) key).

selected_filter: Option<AssetTileKind>

selected_index: Option<usize>

renaming_index: Option<usize>

flat index of the tile currently being inline-renamed, if any.

rename_buffer: String

Edit buffer backing both the tile and folder inline-rename fields.

renaming_folder: Option<String>

Forward-slash path of the folder currently being inline-renamed, if any.

folder_rename_buffer: String

Edit buffer for the folder inline-rename field.

rename_focus_pending: bool

true on the frame a rename starts, so the inline field grabs keyboard focus once (not every frame, which would trap focus).

current_folder: Option<String>

Forward-slash folder path (relative to assets/) currently selected in the tree. "" = root, None initially.

expanded_folders: HashMap<String, bool>

Per-folder expand/collapse state. Keys are full paths; missing = collapsed (root is special-cased to start expanded).

confirm_delete: Option<(String, bool)>

Path awaiting the delete confirmation, and whether it names a folder.

Every delete route parks its target here instead of writing EditorState::pending_delete_asset directly, so the recycle-bin call only happens once the user has answered the dialog.

grid_scroll: ScrollState

How far the tile grid is scrolled.

Implementations

impl AssetBrowserPanel

pub fn new(state: Arc<Mutex<EditorState>>, theme: UiTheme) -> Self

fn render_delete_confirmation( &mut self, ui: &mut dyn UiBuilder, panel_rect: [f32; 4], theme: &UiTheme, )

Asks before sending anything to the recycle bin, and only then queues the deletion for commands::process_pending_asset_file_ops.

Deleting a file is the one action here the editor cannot undo — there is no undo history, and the file leaves the project. A folder takes everything under it, so its wording says so.

fn rescan_if_needed(&mut self)

fn build_folder_tree(&self) -> FolderNode

fn absolute_rel_path(&self, rel: &str) -> Option<String>

Resolves a forward-slash path under assets/ to an absolute OS path, or None when no project is open.

fn absolute_path_for(&self, asset: &FlatAsset) -> Option<String>

fn reveal_in_explorer(&self, rel: &str, is_dir: bool)

Opens the OS file explorer at rel. For a file we reveal its containing folder; for a directory we open the directory itself.

fn reveal_project(&self)

Opens the project root in the OS file explorer.

fn queue_new_folder(&self, parent: &str)

Queues creation of a uniquely-named “New Folder” under parent ("" = assets root), disambiguating against known directories.

fn paint_drag_ghost( &self, ui: &mut dyn UiBuilder, cursor: [f32; 2], name: &str, kind: AssetTileKind, theme: &UiTheme, )

Paints a small chip that follows the cursor while a tile is being dragged, so it’s obvious the user is carrying an asset. Drawn on top of the grid, offset from the pointer so the cursor stays visible.

fn queue_save_entity_as_prefab(&self, entity: EntityId)

Queues saving entity’s subtree as a .kprefab in the current folder, using the entity’s display name as the file stem. Shared by the grid-wide drop target and the per-tile entity-drop handler.

fn activate_asset(&self, asset: &FlatAsset)

fn render_folder_tree( &mut self, ui: &mut dyn UiBuilder, origin_x: f32, origin_y: f32, sidebar_w: f32, theme: &UiTheme, ) -> f32

Render the recursive folder tree in the sidebar’s lower panel. Returns the y coordinate after the last rendered row.

fn render_folder_node( &self, ui: &mut dyn UiBuilder, node: &FolderNode, depth: u32, origin_x: f32, y: &mut f32, sidebar_w: f32, theme: &UiTheme, current: &mut Option<String>, new_expanded: &mut Vec<(String, bool)>, actions: &mut Vec<FolderAction>, rename_rect: &mut Option<[f32; 4]>, )

fn render_breadcrumb( &mut self, ui: &mut dyn UiBuilder, origin_x: f32, origin_y: f32, max_w: f32, theme: &UiTheme, project_folder: &str, )

Render the navigable breadcrumb (project › assets › subfolder ›). Each segment is clickable — sets current_folder.

Trait Implementations

impl EditorPanel for AssetBrowserPanel

fn id(&self) -> &str

Unique identifier (used for dock serialization and lookup).

fn title(&self) -> &str

Human-readable title shown in the tab / panel header.

fn ui(&mut self, ui: &mut dyn UiBuilder)

Build the panel contents for the current frame.

fn preferred_size(&self) -> Option<f32>

Preferred size hint, in logical points.
