Struct FileDialogUiState 

pub struct FileDialogUiState {
    pub visible: bool,
    pub config: FileDialogUiConfig,
    pub thumbnails: ThumbnailCache,
    /* private fields */
}

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

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

Fields

visible: bool

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

config: FileDialogUiConfig

Caller-facing UI configuration.

thumbnails: ThumbnailCache

Thumbnail cache (requests + LRU).

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.
