Expand description

Implement this structure to handle events related to dragging. The functions of this structure will be called on the UI thread.

NOTE: This struct is allocated client-side.

Fields§

§base: cef_base_ref_counted_t

Base structure.

§on_drag_enter: Option<unsafe extern "C" fn(self_: *mut _cef_drag_handler_t, browser: *mut _cef_browser_t, dragData: *mut _cef_drag_data_t, mask: cef_drag_operations_mask_t) -> c_int>

Called when an external drag event enters the browser window. |dragData| contains the drag event data and |mask| represents the type of drag operation. Return false (0) for default drag handling behavior or true (1) to cancel the drag event.

§on_draggable_regions_changed: Option<unsafe extern "C" fn(self_: *mut _cef_drag_handler_t, browser: *mut _cef_browser_t, frame: *mut _cef_frame_t, regionsCount: usize, regions: *const cef_draggable_region_t)>

Called whenever draggable regions for the browser window change. These can be specified using the ‘-webkit-app-region: drag/no-drag’ CSS-property. If draggable regions are never defined in a document this function will also never be called. If the last draggable region is removed from a document this function will be called with an NULL vector.
