beginForDirectory:file:types:modelessDelegate:didEndSelector:contextInfo:

Presents a modeless Open panel.

Declaration

- (void) beginForDirectory:(NSString *) path file:(NSString *) name types:(NSArray *) fileTypes modelessDelegate:(id) delegate didEndSelector:(SEL) didEndSelector contextInfo:(void *) contextInfo;

Parameters

  • path:

    The directory whose files the panel displays. When nil, the directory is the same directory used in the previous invocation of the panel; this is probably the best choice for most situations.

  • name:

    Specifies a particular file in absoluteDirectoryPath that is selected when the Open panel is presented to the user. When nil, no file is initially selected.

  • fileTypes:

    An array of file extensions and/or HFS file types. Specifies the files the panel allows the user to select. nil makes all files in absoluteDirectoryPath selectable by the user. An array of types passed in here will override one set using Allowedfiletypes.

  • delegate:

    This is not the same as a delegate assigned to the panel. This delegate is temporary and the relationship only lasts until the panel is dismissed.

  • didEndSelector:

    The message sent to modelessDelegate after the panel’s session has ended, but before dismissing the Open panel. didEndSelector may dismiss the Open panel itself; otherwise, it will be dismissed on return from the method. The corresponding method should have the following signature:

    - (void)openPanelDidEnd:(NSOpenPanel *)panel returnCode:(int)returnCode  contextInfo:(void  *)contextInfo

    The value passed as returnCode will be either NSCancelButton or NSOKButton.

  • contextInfo:

    Any context information passed to modelessDelegate in the didEndSelector message.

Discussion

Similar to beginSheetForDirectory:file:types:modalForWindow:modalDelegate:didEndSelector:contextInfo:, but allows for modeless operation of the panel.
