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.
