Instance Method

runModal(for:delegate:didRun:contextInfo:)

Runs the print operation, calling your custom delegate method upon completion.

Declaration

func runModal(for docWindow: NSWindow, delegate: Any?, didRun didRunSelector: Selector?, contextInfo: UnsafeMutableRawPointer?)

Parameters

docWindow

The document window to receive a print progress sheet.

delegate

The printing delegate object. Messages are sent to this object.

didRunSelector

The delegate method called after the completion of the print operation.

contextInfo

A pointer to any data you want passed to the method in the didRunSelector parameter.

Discussion

The method specified by the didRunSelector parameter must have the following signature:

- (void)printOperationDidRun:(NSPrintOperation *)printOperation  success:(BOOL)success  contextInfo:(void *)contextInfo

The value of success is true if the print operation ran to completion without cancellation or error, and false otherwise.

If you send canSpawnSeparateThread to an NSPrintOperation object with an argument of true, then the delegate specified in a subsequent invocation of runModal(for:delegate:didRun:contextInfo:) may be messaged in that spawned, non-main thread.
