The following option-value pairs are possible as +command line arguments: + +-initialdir dirname + +Specifies that the directories in directory should be displayed when the +dialog pops up. If this parameter is not specified, then the directories +in the current working directory are displayed. 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. +ToDo: +- Fix bugs. + * + */ +int +Tk_ChooseDirectoryObjCmd(clientData, interp, objc, objv) + ClientData clientData;
