NSPrintOperation
public NSPrintOperation()
printOperationWithView_printInfo
public static NSPrintOperation printOperationWithView_printInfo(NSView view,
NSPrintInfo printInfo)
- Factory methods that create a new NSPrintOperation for printing, copying to Portable Document Format, or copying to Encapsulated PostScript. The passed-in NSPrintInfo is copied, and the copy is retained by the new NSPrintOperation. (So, no need to copy the NSPrintInfo you pass to these.) You can get the copy with -printInfo.
Original signature : +(NSPrintOperation*)printOperationWithView:(NSView*) printInfo:(NSPrintInfo*)
printOperationWithView
public static NSPrintOperation printOperationWithView(NSView view)
- Slight conveniences, for use when the application's global NSPrintInfo is appropriate. Each of these methods invokes [NSPrintInfo sharedPrintInfo] and then invokes the like-named method listed above.
Original signature : +(NSPrintOperation*)printOperationWithView:(NSView*)
currentOperation
public static NSPrintOperation currentOperation()
- The current print operation for this thread. If this is nil, there is no current operation for the current thread.
Original signature : +(NSPrintOperation*)currentOperation
setCurrentOperation
public static void setCurrentOperation(NSPrintOperation operation)
isCopyingOperation
public abstract boolean isCopyingOperation()
- Return YES if the operation for copying to PDF or EPS, NO if it's for printing.
Original signature : -(BOOL)isCopyingOperation
setJobTitle
public abstract void setJobTitle(NSString jobTitle)
- The title of the print job. If a job title is set it overrides anything that might be gotten by sending the printed view an [NSView(NSPrinting) printJobTitle] message.
Original signature : -(void)setJobTitle:(NSString*)
jobTitle
public abstract NSString jobTitle()
setShowsPrintPanel
public abstract void setShowsPrintPanel(boolean flag)
- Whether the print and progress panels are shown during the operation.
Original signature : -(void)setShowsPrintPanel:(BOOL)
showsPrintPanel
public abstract boolean showsPrintPanel()
setShowsProgressPanel
public abstract void setShowsProgressPanel(boolean flag)
showsProgressPanel
public abstract boolean showsProgressPanel()
setPrintPanel
public abstract void setPrintPanel(Pointer panel)
- The print panel to be presented by the operation when it is run, if showsProgressPanel is YES and isCopyingOperation is NO. -printPanel will create a new NSPrintPanel if one hasn't been set yet.
Original signature : -(void)setPrintPanel:(NSPrintPanel*)
printPanel
public abstract Pointer printPanel()
setCanSpawnSeparateThread
public abstract void setCanSpawnSeparateThread(boolean canSpawnSeparateThread)
- Whether the print operation should spawn a separate thread in which to run itself.
Original signature : -(void)setCanSpawnSeparateThread:(BOOL)
canSpawnSeparateThread
public abstract boolean canSpawnSeparateThread()
setPageOrder
public abstract void setPageOrder(int pageOrder)
- The page order that will be used to generate the pages in this job. This is the physical page order of the pages. It depends on the stacking order of the printer, the capability of the app to reverse page order, etc.
Original signature : -(void)setPageOrder:(NSPrintingPageOrder)
- Parameters:
pageOrder - @see org.rococoa.cocoa.appkit.AppKitLibrary#NSPrintingPageOrder
pageOrder
public abstract int pageOrder()
runOperationModalForWindow_delegate_didRunSelector_contextInfo
public abstract void runOperationModalForWindow_delegate_didRunSelector_contextInfo(NSWindow docWindow,
org.rococoa.ID delegate,
org.rococoa.Selector didRunSelector,
Pointer contextInfo)
- Do the print operation, with panels that are document-modal to a specific window. When the operation has been completed, send the message selected by didRunSelector to the delegate, with the contextInfo as the last argument. The method selected by didRunSelector must have the same signature as:
- (void)printOperationDidRun:(NSPrintOperation *)printOperation success:(BOOL)success contextInfo:(void *)contextInfo;
This can only be invoked once. Create a new NSPrintOperation instance for each operation. When this method completes, the object is removed from being the current operation if it is the current operation.
Original signature : -(void)runOperationModalForWindow:(NSWindow*) delegate:(id) didRunSelector:(SEL) contextInfo:(void*)
runOperation
public abstract boolean runOperation()
- Do the print operation, with application-modal panels. Return YES if the operation completed successfully, NO if there was an error or the user cancelled the operation. This can only be invoked once. Create a new NSPrintOperation instance for each operation. When this method completes, the object is removed from being the current operation if it is the current operation.
Original signature : -(BOOL)runOperation
view
public abstract NSView view()
- The view being printed.
Original signature : -(NSView*)view
printInfo
public abstract NSPrintInfo printInfo()
- The print info of the operation. -printInfo always returns a copy of the NSPrintInfo passed into the factory method used to create the print operation, unless -setPrintInfo: has been invoked, in which case it returns the exact same object passed into -setPrintInfo:. So, the factory methods listed above copy the passed-in NSPrintInfo, but -setPrintInfo: doesn't.
Original signature : -(NSPrintInfo*)printInfo
setPrintInfo
public abstract void setPrintInfo(NSPrintInfo printInfo)
context
public abstract NSGraphicsContext context()
- The context for the output of this operation.
Original signature : -(NSGraphicsContext*)context
pageRange
public abstract NSObject pageRange()
- The first through last one-based page numbers of the operation as it's being previewed or printed. The first page number might not be 1, and the page count might be NSIntegerMax to indicate that the number of pages is not known, depending on what the printed view returned when sent an [NSView(NSPrinting) knowsPageRange:] message.
Original signature : -(id)pageRange
currentPage
public abstract int currentPage()
- The current one-based page number of the operation as it's being previewed or printed.
Original signature : -(NSInteger)currentPage
createContext
public abstract NSGraphicsContext createContext()
- Methods that are invoked by the print operation itself as it proceeds. You should not invoke them.
Original signature : -(NSGraphicsContext*)createContext
destroyContext
public abstract void destroyContext()
deliverResult
public abstract boolean deliverResult()
cleanUpOperation
public abstract void cleanUpOperation()
alloc
public static NSPrintOperation alloc()
