`RDrop` class

public sealed class RDrop

A control that accepts dropped files or texts.

Methods

static RDrop Files(Control target, Action<List<string>> dropped, params string[] patterns): The files dropped on the control go to the method, as paths: only those that match one of the patterns («*.csv»; none: all).
static RDrop Text(Control target, Action<string> dropped): A text dropped on the control (from an editor, a browser) goes to the method.
bool Accepts(string path): Whether a file name matches the patterns (true if there are none).
bool Deliver(IEnumerable<string> paths): Gives paths to the method as a drop would: those that match, and only if one does (for the tests, or a «open» that reuses the drop).
void Stop(): The control no longer accepts drops.
