@section{description}
This is the interface for your standard operating system modal file dialogs to open files, save files and select directories.
See also Dialog which makes it a bit simpler without the need to set fileMode and acceptMode manually.
At the moment selecting a directory is only possible with FileDialog.
@section{CLASSMETHODS}
@section{METHOD}
new

@section{ARGUMENT}
okFunc

@section{ARGUMENT}
stripResult
If selecting multiple files (using fileMode 3) then you have the choice of having your okFunc called with a list or with each of the paths as separate items.
If you want to select only one item then use stripResult = true so that your okFunc will be passed the item instead of a list.
@section{list}
## true: okFunc(path1, path2, path3)
## false: okFunc(paths)
