Struct DialogManager 

pub struct DialogManager { /* private fields */ }

Manager for multiple in-UI file browser dialogs (IGFD-style open/display separation).

This is an incremental step toward IGFD-grade behavior:

• Multiple dialogs can exist concurrently (each keyed by a DialogId).
• The caller opens a dialog (open_browser*) and later drives rendering per-frame via show_* / draw_*.

Implementations

impl DialogManager

pub fn new() -> Self

Create a new manager.

pub fn with_fs(fs: Box<dyn FileSystem>) -> Self

Create a new manager using a custom filesystem.

pub fn set_fs(&mut self, fs: Box<dyn FileSystem>)

Replace the manager filesystem.

pub fn fs(&self) -> &dyn FileSystem

Get a shared reference to the manager filesystem.

pub fn open_browser(&mut self, mode: DialogMode) -> DialogId

Open a new in-UI file browser dialog with a default state.

pub fn open_browser_with_state(&mut self, state: FileDialogState) -> DialogId

Open a new in-UI file browser dialog with a fully configured state.

pub fn close(&mut self, id: DialogId) -> Option<FileDialogState>

Close an open dialog and return its state (if any).

pub fn contains(&self, id: DialogId) -> bool

Returns true if the dialog exists in the manager.

pub fn dialog_state(&self, id: DialogId) -> Option<&FileDialogState>

Get immutable access to a dialog state.

pub fn dialog_state_mut(&mut self, id: DialogId) -> Option<&mut FileDialogState>

Get mutable access to a dialog state (to tweak filters/layout/etc).

pub fn show_browser( &mut self, ui: &Ui, id: DialogId, ) -> Option<Result<Selection, FileDialogError>>

Draw a dialog hosted in its own ImGui window (default host config).

If a result is produced (confirm/cancel), the dialog is removed from the manager and the result is returned.

pub fn show_browser_windowed( &mut self, ui: &Ui, id: DialogId, cfg: &WindowHostConfig, ) -> Option<Result<Selection, FileDialogError>>

Draw a dialog hosted in an ImGui window using custom window configuration.

If a result is produced (confirm/cancel), the dialog is removed from the manager and the result is returned.

pub fn draw_browser_contents( &mut self, ui: &Ui, id: DialogId, ) -> Option<Result<Selection, FileDialogError>>

Draw only the dialog contents (no host window) for embedding.

If a result is produced (confirm/cancel), the dialog is removed from the manager and the result is returned.

Trait Implementations

impl Debug for DialogManager

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

Formats the value using the given formatter.

impl Default for DialogManager

fn default() -> Self

Returns the “default value” for a type.
