/*
 * @file General dialog base class
 *
 * Base class which provides convenience methods for dialogs that handle
 * capture files.
 *
 * This class attempts to destroy itself when closed. Doing this safely and
 * properly can be a bit tricky while scanning and tapping packets since

// "General" is a misnomer but we already have a class named
// "CaptureFileDialog". Suggestions for a better name from
// https://code.wireshark.org/review/#/c/9739/:
// BaseCaptureDialog, CaptureHelperDialog (or rename CaptureFileDialog to something else - WiresharkFileDialog).
// TapDialog might make sense as well.
