#RunHWDialog(settings) ⇒ Symbol

Note:

This is a stable API function

Draw the dialog, handle all its events via callbacks

Parameters:

  • settings (Hash)

    a map containing all the settings: $[ "action_callback" : symbol(string,map) -- callback to handle all events which aren't handled internally, first parameter is the ID of the selected item, second is the event. If not set, events which are symbols are returned to wizard sequencer "set_items_callback" : void() -- callback to set the items to be displayed. Should called WizardHW::SetContents instead of direct widgets modification, as it stores the settings also internally. This callback must be set. "set_initial_item_callback" : void() -- callback to set the selected item when dialog initialized. Should call the function WizardHW::SetSelectedItem instead of manual widget modification. If not set, the first item is selected. "item_descr_callback" : string(string) -- callback to get rich text description of the item if it is intended to be dynamical. if not set, static description set via "set_items_callback" is used. "actions" : list -- a list of actions to be offered via additional button next to Add/Edit/Delete button. Each item is a two-item-list, where the first item is the event ID and the second item is the label of the entry of the menu button. If there is only one entry, menu button is replaced by push button. If empty (or not specifued), nothing is shown. "title" : string -- the dialog title, must be specified "help" : string -- the help for the dialog, must be specifed "headers" : list -- a list of the table headers, must be specified "next_button" : string -- label for the "Next" button. To hide it, set to nil. If not specified, "Next" is used. "back_button" : string -- label for the "Back" button. To hide it, set to nil. If not specified, "Back" is used. "abort_button" : string -- label for the "Abort" button. To hide it, set to nil. If not specified, "Abort" is used. ]

Returns:

  • (Symbol)
