Contents - Software documentation for the NSSavePanel class Software documentation for the NSObject(NSOpenSavePanelDelegate) informal protocol Software documentation for the NSObject(NSSavePanelDelegate) informal protocol Software documentation for the NSOpenSavePanelDelegate protocol Software documentation for the NSSavePanel class NSSavePanel : NSPanel Declared in: AppKit/NSSavePanel.h Availability: OpenStep Implements a panel that allows the user to save a file. There is only one save panel per application and this panel is obtained by calling the +savePanel class method. From here, you should set the required file extension using -setRequiredFileType: When ready to show the panel, use the -runModal , or a similar method to show the panel in a modal session. Other methods allow you to set the initial directory and initially choosen file. The method will return one of NSOKButton or NSCancelButton depending on which button the user pressed. Use the -filename method to retrieve the name of the file the user choose.

Saves the current directory browsed and stop the modal event loop using [NSApplication -stopModalWithCode:] See Also: -ok: directory - ( NSString *) directory ; Availability: OpenStep Returns the directory choosen by the user. Do not invoke directory within a modal loop because the information that these methods fetch is updated only upon return. See Also: -setDirectory: directoryURL - ( NSURL *) directoryURL ; Availability: MacOS-X 10.6.0 Description forthcoming. filename - ( NSString *) filename ; Availability: OpenStep Returns the absolute filename choosen by the user. Do not invoke filename within a modal loop because the information that these methods fetch is updated only upon return. isExpanded - (BOOL) isExpanded ; Availability: MacOS-X 10.0.0 Description forthcoming. isExtensionHidden - (BOOL) isExtensionHidden ; Availability: MacOS-X 10.2.0 Description forthcoming. message - ( NSString *) message ; Availability: MacOS-X 10.3.0 Description forthcoming. nameFieldLabel - ( NSString *) nameFieldLabel ; Availability: MacOS-X 10.3.0 Description forthcoming. nameFieldStringValue - ( NSString *) nameFieldStringValue ; Availability: MacOS-X 10.6.0 Description forthcoming. ok: - (void) ok: (id)sender; Availability: OpenStep Invoked by the "OK" button. See Also: -cancel: prompt - ( NSString *) prompt ; Availability: OpenStep Returns the prompt used in the current path field. See Also: -setPrompt: requiredFileType - ( NSString *) requiredFileType ; Availability: OpenStep Returns the required file type. The default, indicated by an empty string, is no required file type. This method is equivalent to calling -allowedFileTypes and returning the first element of the list of allowed types, or the empty string if there are none. See Also: -setRequiredFileType: runModal - ( NSInteger ) runModal ; Availability: OpenStep Shows the save panel for the user. This method invokes -runModalForDirectory:file: with empty strings for the filename. Returns NSOKButton (if the user clicks the OK button) or NSCancelButton (if the user clicks the Cancel button). See Also: -runModalForDirectory:file: runModalForDirectory: file: - ( NSInteger ) runModalForDirectory: ( NSString *)path file: ( NSString *)filename; Availability: OpenStep Initializes the panel to the directory specified by path and, optionally, the file specified by filename , then displays it and begins its modal event loop; path and filename can be empty strings. The method invokes [NSApplication:-runModalForWindow:] method with self as the argument. Returns NSOKButton (if the user clicks the OK button) or NSCancelButton (if the user clicks the Cancel button). If path is nil then the panel displays the last selected directory or as a last resort, the current working directory. See Also: -runModal runModalForDirectory: file: relativeToWindow: - ( NSInteger ) runModalForDirectory: ( NSString *)path file: ( NSString *)filename relativeToWindow: ( NSWindow *)window; Availability: MacOS-X 10.0.0 Description forthcoming. selectText: - (void) selectText: (id)sender; Availability: OpenStep Description forthcoming. setAccessoryView: - (void) setAccessoryView: ( NSView *)aView; Availability: OpenStep Sets an accessory view which is shown near the bottom of the panel. The panel is automatically expanded with enough room to show the extra view. You can use this extra view to customize various characteristics of the file selection mechanism. For instance you could add a popup button which allows the user to select the format that the file is saved in (e.g. rtf or txt). See also -validateVisibleColumns . See Also: -accessoryView setAllowedFileTypes: - (void) setAllowedFileTypes: ( NSArray *)types; Availability: MacOS-X 10.3.0 Specifies the allowed types , i.e., file name extensions to be appended to any selected files that don't already have one of those extensions. The elements of the array should be strings that do not include the period that begins the extension. Invoke this method each time the Save panel is used for another file type within the application. If you do not invoke it, or set it to an empty array or nil , no extension will be appended, indicated by nil returned from -allowedFileTypes . See Also: -allowedFileTypes setAllowsOtherFileTypes: - (void) setAllowsOtherFileTypes: (BOOL)flag; Availability: MacOS-X 10.3.0 Description forthcoming. setCanCreateDirectories: - (void) setCanCreateDirectories: (BOOL)flag; Availability: MacOS-X 10.3.0 Description forthcoming. setCanSelectHiddenExtension: - (void) setCanSelectHiddenExtension: (BOOL)flag; Availability: MacOS-X 10.2.0 Description forthcoming. setDirectory: - (void) setDirectory: ( NSString *)path; Availability: OpenStep Sets the current path name in the Save panel's browser. The path argument must be an absolute path name. See Also: -directory setDirectoryURL: - (void) setDirectoryURL: ( NSURL *)url; Availability: MacOS-X 10.6.0 Sets the current path name in the Save panel's browser. The path argument must be an absolute path name. See Also: -directory setExtensionHidden: - (void) setExtensionHidden: (BOOL)flag; Availability: MacOS-X 10.2.0 Description forthcoming. setMessage: - (void) setMessage: ( NSString *)message; Availability: MacOS-X 10.3.0 Description forthcoming. setNameFieldLabel: - (void) setNameFieldLabel: ( NSString *)label; Availability: MacOS-X 10.3.0 Description forthcoming. setNameFieldStringValue: - (void) setNameFieldStringValue: ( NSString *)value; Availability: MacOS-X 10.6.0 Description forthcoming. setPrompt: - (void) setPrompt: ( NSString *)prompt; Availability: OpenStep Returns the prompt of the Save panel field that holds the current pathname or file name. By default this prompt is 'Name: '. See Also: -prompt setRequiredFileType: - (void) setRequiredFileType: ( NSString *)fileType; Availability: OpenStep Specifies the type, a file name extension to be appended to any selected files that don't already have that extension; The argument type should not include the period that begins the extension. Invoke this method each time the Save panel is used for another file type within the application. If you do not invoke it, or set it to empty string or nil , no extension will be appended, indicated by an empty string returned from -requiredFileType . This method is equivalent to calling -setAllowedFileTypes: with an array containing only fileType . See Also: -requiredFileType setShowsHiddenFiles: - (void) setShowsHiddenFiles: (BOOL)flag; Availability: MacOS-X 10.6.0 Description forthcoming. setTitle: - (void) setTitle: ( NSString *)title; Availability: OpenStep Sets the title of the NSSavePanel to title . By default, 'Save' is the title string. If you adapt the NSSavePanel for other uses, its title should reflect the user action that brings it to the screen. See Also: -title setTreatsFilePackagesAsDirectories: - (void) setTreatsFilePackagesAsDirectories: (BOOL)flag; Availability: OpenStep Sets the NSSavePanel's behavior for displaying file packages (for example, MyApp.app) to the user. If flag is YES , the user is shown files and subdirectories within a file package. If NO , the NSSavePanel shows each file package as a file, thereby giving no indication that it is a directory. See Also: -treatsFilePackagesAsDirectories showsHiddenFiles - (BOOL) showsHiddenFiles ; Availability: MacOS-X 10.6.0 Description forthcoming. title - ( NSString *) title ; Availability: OpenStep Returns the title of the save panel See Also: -setTitle: treatsFilePackagesAsDirectories - (BOOL) treatsFilePackagesAsDirectories ; Availability: OpenStep Returns YES if file packages are shown as directories. The default is NO . validateVisibleColumns - (void) validateVisibleColumns ; Availability: OpenStep Validates and possibly reloads the browser columns that are visible in the Save panel by causing the delegate method -panel:shouldShowFilename: to be invoked. One situation in which this method would find use is whey you want the browser to show only files with certain extensions based on the selection made in an accessory-view pop-up list. When the user changes the selection, you would invoke this method to revalidate the visible columns.
