UI-only state for hosting a FileDialogCore in Dear ImGui.

This struct contains transient UI state (visibility, focus requests, text buffers) and does not affect the core selection/navigation semantics.

Fields

visible: bool

Whether to draw the dialog (show/hide). Prefer FileDialogState::open/FileDialogState::close.

header_style: HeaderStyle

Header layout style.

layout: LayoutStyle

Layout style for the dialog UI.

validation_buttons: ValidationButtonsConfig

Validation button row configuration (Ok/Cancel).

toolbar: ToolbarConfig

Top toolbar (“chrome”) configuration.

places_pane_shown: bool

Whether to show the left “Places” pane in LayoutStyle::Standard.

places_pane_width: f32

Width of the left “Places” pane in pixels (Standard layout only).

file_list_view: FileListViewMode

File list view mode (list vs grid).

file_list_columns: FileListColumnsConfig

List-view column visibility configuration.

path_bar_style: PathBarStyle

Path bar style (editable text input vs breadcrumb-style composer).

path_input_mode: bool

When true (and path_bar_style is PathBarStyle::Breadcrumbs), show the editable path text input instead of the breadcrumb composer.

This mimics IGFD’s path composer “Edit” toggle behavior.

breadcrumbs_quick_select: bool

Enable quick parallel directory selection popups when clicking breadcrumb separators.

This mimics IGFD’s “quick path selection” feature in the path composer.

breadcrumbs_max_segments: usize

Max breadcrumb segments to display (compress with ellipsis when exceeded).

empty_hint_enabled: bool

Show a hint row when no entries match filters/search.

empty_hint_color: [f32; 4]

RGBA color of the empty hint text.

empty_hint_static_message: Option<String>

Custom static hint message when entries list is empty; if None, a default message is built.

path_edit: bool

Whether the path input is currently being edited (best-effort; updated by UI).

This is UI-only state and should not be treated as a stable API contract.

path_edit_buffer: String

Path input buffer (editable “address bar”).

focus_path_edit_next: bool

Focus path edit on next frame.

focus_search_next: bool

Focus search on next frame (Ctrl+F).

ui_error: Option<String>

Error string to display in UI (non-fatal).

new_folder_enabled: bool

Whether to show and allow the “New Folder” action.

new_folder_inline_active: bool

Whether the “New Folder” inline editor is active (toolbar-local, IGFD-like).

new_folder_open_next: bool

Open the “New Folder” modal on next frame.

new_folder_name: String

New folder name buffer (used by the “New Folder” modal).

new_folder_focus_next: bool

Focus the new folder input on next frame.

new_folder_error: Option<String>

Error string shown inside the “New Folder” modal.

rename_open_next: bool

Open the “Rename” modal on next frame.

rename_focus_next: bool

Focus the rename input on next frame.

rename_target_id: Option<EntryId>

Rename target entry id.

rename_to: String

Rename “to” buffer.

rename_error: Option<String>

Error string shown inside the rename modal.

delete_open_next: bool

Open the “Delete” confirmation modal on next frame.

delete_target_ids: Vec<EntryId>

Pending delete target ids.

delete_recursive: bool

Whether directory deletion should be recursive (remove_dir_all) instead of requiring empty directories.

delete_error: Option<String>

Error string shown inside the delete modal.

clipboard: Option<FileClipboard>

Clipboard state for copy/cut/paste operations.

file_style_fonts: HashMap<String, FontId>

Optional font mapping used by file style font_token.

file_styles: FileStyleRegistry

Style registry used to decorate the file list (icons/colors/tooltips).

thumbnails_enabled: bool

Enable thumbnails in the file list (adds a Preview column).

thumbnail_size: [f32; 2]

Thumbnail preview size in pixels.

thumbnails: ThumbnailCache

Thumbnail cache (requests + LRU).

type_select_enabled: bool

Enable “type-to-select” behavior in the file list (IGFD-style).

type_select_timeout_ms: u64

Timeout (milliseconds) after which the type-to-select buffer resets.

custom_pane_enabled: bool

Whether to render a custom pane region (when a pane is provided by the caller).

custom_pane_dock: CustomPaneDock

Dock position for the custom pane.

custom_pane_height: f32

Height of the custom pane region (in pixels).

custom_pane_width: f32

Width of the custom pane region when right-docked (in pixels).

Implementations

impl FileDialogUiState

pub fn apply_igfd_classic_preset(&mut self)

Applies an “IGFD classic” UI preset (opt-in).

This tunes UI defaults to feel closer to ImGuiFileDialog (IGFD) while staying Rust-first:

• standard layout with places pane,
• IGFD-like single-row header layout,
• list view as the default,
• right-docked custom pane (when provided) with a splitter-resizable width,
• dialog-style button row aligned to the right.

Trait Implementations

impl Debug for FileDialogUiState

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for FileDialogUiState

fn default() -> Self

Returns the “default value” for a type.
