Resize Piece Dialog sets the length of musical piece.
Since WIDI 4.0 it is possible to increase piece length just by scrolling editing area beyond the right edge, so this tool is rarely used.
The Resize Piece Dialog is brought up by selecting the menu item "Operations->Set Piece Length".
Set Length to set the piece duration.
Note: with decreasing the length some notes may be lost irreversibly.
OK button confirms resize, Cancel closes the dialog without any action, Help opens current help page.
