[MacRuby-devel] allowedFileTypes and NSOpenPanel

[Matt Aimonetti]

Here is an extract from one of my apps:

  def browse(sender)
    # Create the File Open Dialog class.
    dialog = NSOpenPanel.openPanel
    # Disable the selection of files in the dialog.
    dialog.canChooseFiles = false
    # Enable the selection of directories in the dialog.
    dialog.canChooseDirectories = true
    # Disable the selection of multiple items in the dialog.
    dialog.allowsMultipleSelection = false

    # Display the dialog and process the selected folder
    if dialog.runModalForDirectory(nil, file:nil) == NSOKButton
      selection = dialog.filenames.first
      location.stringValue = dialog.filenames.first.to_s
    end
  end

Note that location is an attr_accessor that I have and the the #browser
method gets called when pushing a button.

I hope that helps.
