# beginSheet(with:modalFor:delegate:didEnd:contextInfo:)

Displays a Print panel sheet and runs it modally for the specified window.

## Declaration

```swift
func beginSheet(with printInfo: NSPrintInfo, modalFor docWindow: NSWindow, delegate: Any?, didEnd didEndSelector: Selector?, contextInfo: UnsafeMutableRawPointer?)
```

## Parameters

- `printInfo`: The printing information for the current job.
- `docWindow`: The window on which to display the sheet.
- `delegate`: A modal delegate object assigned to handle the closing of the Print panel sheet.
- `didEndSelector`: The selector to call on the modal delegate object when the sheet is dismissed. The signature of this method is listed in the Discussion section.
- `contextInfo`: A pointer to context data the didEndSelector method needs to process the sheet. This data is user-defined and may be NULL.

## Discussion

Discussion When the modal session ends, if modalDelegate and didEndSelector contain non-nil values, the method specified by didEndSelector is invoked on the object in modalDelegate. The data you specify in contextInfo is passed as a parameter to the didEndSelector method. The object in modalDelegate is not the same as a delegate assigned to the panel. Modal delegates for sheets are temporary and the relationship lasts only until the sheet is dismissed. The didEndSelector argument must have the following signature: - (void)printPanelDidEnd:(NSPrintPanel *)printPanel returnCode:(NSInteger)returnCode  contextInfo: (void *)contextInfo; The value passed as returnCode is either NSCancelButton or NSOKButton. The value NSOKButton is returned even if the user clicked the Preview button.
