// TODO(dialog-refactor):
|
|
// Currently this module (`handle_dialog_event`) contains page-specific logic
|
|
// (e.g. Login, Register, Admin, SaveTable). This couples the dialog crate
|
|
// to application pages and business logic.
|
|
//
|
|
// Refactor plan:
|
|
// 1. Keep dialog generic: only handle navigation (next/prev/select) and return
|
|
// a `DialogResult` (Dismissed | Selected { purpose, index }).
|
|
// 2. Move all page-specific actions (e.g. login::back_to_main, register::back_to_login,
|
|
// handle_delete_selected_columns, buffer_state.update_history) into the
|
|
// respective page or event handler (e.g. modes/handlers/event.rs).
|
|
// 3. Dialog crate should only provide state, rendering, and generic navigation.
|
|
// Pages decide what to do when a dialog button is pressed.
