/** abstract base class for implementing UNO objects representing asynchronous dialogs
|
|
|
|
Contrary to StartExecuteAsync in VclAbstractDialog from include/vcl/abstdlg.hxx,
|
|
the different methods are used in a special case when an import or export action
|
|
wants to show a dialog, as part of a synchronous filter() API call.
|
|
|
|
In this case it's not possible to move the "rest of the code" to an async
|
|
callback, so that needs special handling. Luckily these dialogs are rather rare.
