In 4D 2004, there is a new window type named "sheet window" which has been added for Mac OS X . The current value of the designated constant is 33. Sheet window has identical properties to those of modal dialog boxes. You can only create a sheet window if the last open window is visible and of the document type (form). The code example below demonstrates how a sheet window can be created.

`Open sheet window method

Open window(10;10;400;200;Sheet window)
DIALOG([TableName];"FormName")
