|
|
This class provides the file selection dialog. It incorporates OS-native features
|
|
depending on the OS in use, and can be used both for open and save operations.
|
|
The files displayed can be filtered by setting up a wildcard filter, multiple files
|
|
can be selected (open only), and files can be forced in a read-only mode.
|
|
|
|
There are two ways to get the results back from the dialog. GetFiles() returns only
|
|
the file names themselves, in a Python list. GetPaths() returns the full path and
|
|
filenames combined as a Python list.
