module ui.mojom;

// Specifies the type of modality applied to a window. Different modal
// treatments may be handled differently by the window manager.
enum ModalType {
  // Window is not modal.
  kNone,

  // Window is modal to its transient parent.
  kWindow,

  // Window is modal to a specific child UI element (and its descendants) of its
  // transient parent. Other UI elements remain interactive.
  //
  // Example: A tab-modal dialog disables input *only* to that tab's contents.
  //
  // The application is responsible for managing this modality. The OS window
  // manager is unaware of it. The client must disable input to the target child
  // UI and its descendants while the modal window is active.
  kChild,

  // Window is modal to all other windows.
  // Only supported on ChromeOS.
