If the parameter specifies a * relative path, the return value will convert the relative path to an * absolute path. This option may not always work on the Macintosh. This is * not a bug. Rather, the General Controls control panel on the Mac allows the * end user to override the application default directory. * * -parent window * * Makes window the logical parent of the dialog. The dialog is displayed on * top of its parent window. * * -title titleString * * Specifies a string to display as the title of the dialog box. If this * option is not specified, then a default title will be displayed. * * -mustexist boolean * * Specifies whether the user may specify non-existant directories. If this * parameter is true, then the user may only select directories that already * exist. The default value is false. * * New Behaviour: * * - If mustexist = 0 and a user entered folder does not exist, a prompt will * pop-up asking if the user wants another chance to change it. The old * dialog just returned the bogus entry. On mustexist = 1, the entries MUST * exist before exiting the box with OK. * * Bugs: * * - If valid abs directory name is entered into the entry box and Enter * pressed, the box will close returning the name. This is inconsistent when * entering relative names or names with forward slashes, which are * invalidated then corrected in the callback. After correction, the box is * held open to allow further modification by the user. * * - Not sure how to implement localization of message prompts. * * - -title is really -message. * ToDo: * - Fix bugs. * - test to see what platforms this really works on.
