Description

This Tk widget enables you to delete regions-of-interest (or more simply, regions - see Regionmanager) stored in an AIPS++ Table. It can also be used to provide a GUI interface for deleting regions from a record or global name space (from Glish).

The widget displays, in listboxes, the regions stored in the Table (or record or Glish). The `Delete' button is used to delete the regions that you have selected. The `Delete all' button deletes all regions. The `Deselect' button deselects all regions. Optionally, you can be prompted for confirmation before deletion by selecting from the `Confirm' menu. The `Dismiss' button dismisses the GUI. You can recover it with the gui function.

Under the `File' menu, you can either dismiss the GUI or destroy the widget (same as invoking function done).

The Table can be specified in many ways (at construction and via the entry box in the GUI); a Table tool, an Image) tool, the name of a Table (a string) which might be an AIPS++ image, or the name of a Glish symbol which is either a Table or an Image tool.

This widget emits an event called deleted (it has no value) when the regions have been deleted. It also emits an event called dismissed (it has no value) when the dismiss button on the GUI is pressed.
