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
didRunSelectorparameter.
Discussion
The method specified by the didRunSelector parameter must have the following signature:
- (void)printOperationDidRun:(NSPrintOperation *)printOperation success:(BOOL)success contextInfo:(void *)contextInfoThe 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.
