Implements a panel that allows the user to select a file or files. NSOpenPanel is based on the NSSavePanel implementation and shares a lot of similarities with it.
There is only one open panel per application and this panel is obtained by calling the +openPanel
class method. From here, you should set the characteristics of the file selection mechanism using the -setCanChooseFiles:
, -setCanChooseDirectories:
and -setAllowsMultipleSelection:
methods. The default is YES
except for allowing multiple selection. When ready to show the panel, use the -runModalForTypes:
, or a similar method to show the panel in a modal session. Other methods allow you to set the initial directory and initially selected file. The method will return one of NSOKButton or NSCancelButton depending on which button the user pressed.
Use the [NSSavePanel -filename] or -filenames method to retrieve the name of the file the user selected.
