Struct FileDropManager 

pub struct FileDropManager { /* private fields */ }

Manager for file drop state and hovered file tracking.

MWA-B7: stores ALL files of a drag/drop (multi-file drops were silently truncated to the first path at every OS ingress site — the manager could only hold one). The single-file accessors remain as first-element views for existing callers.

Implementations

impl FileDropManager

pub const fn new() -> Self

Create a new file drop manager

pub fn set_hovered_files(&mut self, files: Vec<AzString>)

Set ALL currently hovered files (MWA-B7). An empty vec behaves like a drag-leave (latches the hover-cancel flag).

pub fn set_hovered_file(&mut self, file: Option<AzString>)

Single-file compatibility shim over set_hovered_files.

Platform backends call this with Some(path) on drag-enter (macOS draggingEntered, Windows OLE IDropTarget::DragEnter) and None on drag-leave (draggingExited / DragLeave). A Some -> None transition latches FileDropManager::hover_was_cancelled so the FileHoverCancel event can fire.

pub const fn hover_was_cancelled(&self) -> bool

Whether a hover ended without a drop since the last FileDropManager::clear_hover_cancelled (one-shot).

pub const fn clear_hover_cancelled(&mut self)

Clear the one-shot hover-cancel flag. Called by the platform drag handler after determine_all_events has emitted the FileHoverCancel event (mirrors the dropped-files reset after FileDrop).

pub fn get_hovered_file(&self) -> Option<&AzString>

First hovered file (single-file view; use get_hovered_files for the full list).

pub fn get_hovered_files(&self) -> &[AzString]

ALL currently hovered files (MWA-B7).

pub fn get_dropped_file(&self) -> Option<&AzString>

First dropped file (single-file view; use get_dropped_files for the full list).

pub fn get_dropped_files(&self) -> &[AzString]

ALL files of the drop this frame (MWA-B7; one-shot, cleared by the platform handler after event processing).

pub fn set_dropped_files(&mut self, files: Vec<AzString>)

Set ALL dropped files (MWA-B7; cleared after one frame).

pub fn set_dropped_file(&mut self, file: Option<AzString>)

Single-file compatibility shim over set_dropped_files.
