* @param owner the owner of the file dialog
* @param open if {@code true}, shows the open dialog; if {@code false}, shows the save dialog
* @param title text displayed in dialog title; or {@code null}
* @param okButtonLabel text displayed in default button; or {@code null}
* @param fileNameLabel text displayed in front of the filename text field; or {@code null}
* @param fileName user-editable filename currently shown in the filename field; or {@code null}
* @param folder current directory shown in the dialog; or {@code null}
* @param saveAsItem file to be used as the initial entry in a Save As dialog; or {@code null}.
* File name is shown in filename text field, folder is selected in view.
* To be used for saving files that already exist. For new files use {@code fileName}.
* @param defaultFolder folder used as a default if there is not a recently used folder value available; or {@code null}.
* Windows somewhere stores default folder on a per-app basis.
* So this is probably used only once when the app opens a file dialog for first time.
* @param defaultExtension default extension to be added to file name in save dialog; or {@code null}
* @param optionsSet options to set; see {@code FOS_*} constants
* @param optionsClear options to clear; see {@code FOS_*} constants
* @param fileTypeIndex the file type that appears as selected (zero-based)
* @param fileTypes file types that the dialog can open or save.
* Pairs of strings are required.
* First string is the display name of the filter shown in the combobox (e.g. "Text Files").
* Second string is the filter pattern (e.g. "*.txt", "*.exe;*.dll" or "*.*").
* @return file path(s) that the user selected; an empty array if canceled;
* or {@code null} on failures (no dialog shown)
