In my TestDocument (subclass of NSDocument) I added the following code (see comments inside, which explain what's happening when I do File → Print...):
- (NSPrintOperation *)printOperationWithSettings:(NSDictionary *)printSettings error:(NSError **)outError
{
NSLog(@"%s printSettings %@, outError %p",__FUNCTION__, printSettings, outError);
// -[TestDocument printOperationWithSettings:error:] printSettings {}, outError 0x7fff5fbfed38
NSPrintInfo *pi = [ self printInfo ];
NSLog(@"%s printInfo %@",__FUNCTION__, pi);
#if 0
-[TestDocument printOperationWithSettings:error:] printInfo
{
NSBottomMargin = 90;
NSCopies = 1;
NSDetailedErrorReporting = 0;
[...]
NSVerticalPagination = 0;
NSVerticallyCentered = 1;
}
#endif
NSPrintOperation *op = [ NSPrintOperation printOperationWithView: textView printInfo: pi ];
NSLog(@"%s NSPrintOperation %@ - now run modal",__FUNCTION__, op);
// NSPrintOperation <NSConcretePrintOperation: 0x1003b8900> - now run modal
[ self runModalPrintOperation: op
delegate: nil
didRunSelector: NULL
contextInfo: NULL
];
NSLog(@"%s will return %@",__FUNCTION__, op); // ← never comes to here
// and also no PrintPanel is shown.
// if paused, we get this bt:
#if 0
#0 0x00007fff8e21e08e in _dispatch_semaphore_wait_slow ()
#1 0x00007fff8eb8a616 in -[NSDocument performActivityWithSynchronousWaiting:usingBlock:] ()
#2 0x00007fff8eb7a518 in -[NSDocument runModalPrintOperation:delegate:didRunSelector:contextInfo:] ()
#3 0x0000000100001a2d in -[TestDocument printOperationWithSettings:error:] (self=0x10013e1e0, _cmd=0x7fff8f081f50, printSettings=0x1001161e0, outError=0x7fff5fbfed38) at TestDocument.m:274
#endif
return op;
}
This code above is taken from some other app, which prints just fine in SnowLeopard (but also hangs in Lion).
What am I doing wrong?
Why is there no PrintPanel shown? Why does it just block?
Kind regards,
Gerriet.
