Non-Standard File Unit
The SFGetFile and SFPutFile routines are two of the most commonly used calls in the Macintosh. All programmers need methods to select files (old or new ones) from inside their programs. Only old non-Mac programmers and users really appreciate how much Apple improved the user interface by standardizing this file selection process. However, Apple does not have a monopoly on good user interface ideas. Recently, newer programs have improved the Get and Put dialogs. While these new dialogs have the same functionality as the old ones, they have useful enhancements.
The code provided in this article shows how to create enhanced get and put dialogs. The unit NonStandardFile contains four procedures which demonstrate this. The program NonStandardFileTest shows how to use these routines.
NSPutFile()
The Non-Standard File Put procedure is the first routine provided in the Non-Standard File Unit. This procedure, and all other procedures explained in this article, are passed input parameters (passed by value) and return the output parameters (passed as VAR parameter). NSPutFile contains two input parameters (strings thePrompt and theOrigName) and 3 output parameters (boolean theGood, integer theRefNum and string theFileName). ThePrompt is the prompt that appears in the dialog, and theOrigName is the name that initially appears in the editable text field. If the user selects a file name (pressing the Save button or the return key), theGood flag returns TRUE, while the file name and the volume reference number is in theRefNum and theFileName parameters. If the user selects cancel, theGood returns FALSE.
This is the simplest example of using the SFPPutFile ROM call instead of the normal SFPutFile ROM call. I always find that the prompt portion of a normal SFPutFile is much too short to hold any meaningful information. The NSPutFile procedure provides an modified Put dialog, identical to a normal Put dialog, except the prompt text item is physically expanded (longer and 2 lines high). The routine does this by using a Dialog template resource and a Dialog Item List resource that are almost identical the the normal resources (stored at ID number -3999). The only difference in the resources is that the prompt field is larger. The SFPPutFile call that NSPutFile uses is passed the ID number of this modified dialog. Other than having a different layout, the dialog functions identical to the standard form. It is important to note that whenever a dialog item list is modified, all of the standard items are in the identical order (this is important for the SFPPutFile call). New items can be added to the end of the list (following calls are examples of this), but the original items must still exist.
NSSelectPutFile()
The Non-Standard Selection Put File procedure is the first example of a more intelligent Put dialog. This procedure places a Put dialog on the screen that contains, besides the normal features, 2 buttons to indicate if the user wants to save the entire document or only the selected portion of the document. The procedure is passed 3 input parameters (strings thePrompt, theSelectPrompt, theOrigName) and 4 output parameters (boolean theGood, integer theRefNum, string theFileName, Boolean theFlag). As before, theOrigName is the initial name of the file, while theGood flag returns TRUE if the user selects a file (with theRefNum and theFileName containing the volume reference number and file name selected). However, the routine passes 2 prompt strings, thePrompt and theSelectPrompt. How the button is set affects the appearance of the prompt. If the Document button is set, thePrompt string is displayed in the dialog. If the Selection button is set, theSelectPrompt string is displayed. If at any time, the user changes the button settings, the prompt also changes. If the user selects a file with the Selection button set, theFlag parameter returns TRUE. If he selected a file with the Document button set, theFlag returns FALSE. Having the Document button selected is the initial state of the dialog.
The NSSelectPutFile procedure is very useful when working with documents that can be saved as a whole or saved in portions. For example, a drawing program that allows the user to select various graphical objects on the screen could use this procedure. When the user selects Save from the menu, he can save the entire document, or he can save the selected drawing objects.
Similar to NSPutFile, NSSelectPutFile uses SFPPutFile ROM call in order to use a modified Dialog template and Dialog Item List. However, this list has additional items on it, namely the Document and Selection buttons. The SFPPutFile call also passes a dlogHook routine, NSSelectPutDlg. A dlogHook routine is called by the SFPPutFile call immediately after calling ModalDialog. The dlogHook routine is passed the item number returned by ModalDialog, as well as a pointer to the dialog record. All dlogHook routines (as well as File Filter routines and UserItem routines) need to be declared global to the unit.
The NSSelectPutDlg has two purposes. The first time it is called, the correct prompt is placed in the window and the Document and Selection buttons are set appropriately. After that, the routine scans item events to check if the user has selected either button. If he has, the new prompt is placed in the dialog and the buttons checked appropriately. Also, the item number is set to 100, indicating nothing else needs to be done for this event.
NSIconPutFile()
The Non-Standard Icon Put File procedure is one of the best new user interfaces I have seen on the Macintosh. This routine should be used in a program where a document can be saved as more than one file type. When this routine is used, the desktop icons of the file formats to which the document can be saved are shown.
NSIconPutFile allows up to 4 different file formats (icons). The parameters reflect this. NSIconPutFile is passed 14 input parameters (string theOrigName, integer theDefaultNum, handles theIcon1, theIcon2, theIcon3, theIcon4 and strings theName1, theName2, theName3, theName4, thePrompt1, thePrompt2, thePrompt3, and thePrompt4) and passed 4 output parameters (Boolean theGood, integer theRefNum, string theFileName, integer theNum). TheOrigName, theGood, theRefNum and theFileName are all used identically to the previously explained Non-Standard Put File calls. TheIcon parameters should contain up to 4 icon handles. Each handle should contain 256 byte of information of the ICN# resource format (32 bit by 32 bit image, 128 bytes of image, 128 bytes of mask). Usually, this is the actual ICN# resource that is stored in the application (but it does not have to be). Passing NIL in one of the parameter handles indicates that a particular icon position is not used. For example, if only 3 icons need to be displayed, the last handle should be passed as NIL. TheDefaultNum parameter indicates which icon should be initially set. TheName strings are the titles of the icons (which will appear under the icon), while thePrompt strings are the prompt that will appear when that associated icon is selected. Usually the icon titles are the name of that file type (ie. Text, MacPaint, MacWrite), but this does not have to be the case.
Again imagine this routine is used by a graphic program, but in this case the program is a paint program. The document might be able to be saved as a MacPaint file, or as a StartUp Screen file or as some proprietary file format. Instead of using buttons, the user selects the format he wants by selecting the actual icon. He is used to seeing this icon on the desktop, and associating it with that type of file.
NSIconPutFile uses a number of hooks to function. First the routine calls SFPPutFile in order to use a Dialog template and Dialog item list that have 6 new UserItems on it. Like NSSelectPutFile, NSIconPutFile has a dlogHook routine, NSIconPutDlg. The first time through, NSIconPutDlg sets the prompt and sets the UserItem routine of the 4 new dialog items to NSIconItem. A UserItem routine is a graphic routine that draws some special user interface in a dialog. In this case, NSIconItem draws the 4 icons, with titles and hiliting. NSIconPutDlg handles the mouse down events on the icon. Selecting a previously unselected icon activates the icon, which consists of unhiliting old icon, hiliting new one and setting new prompt.
NSGetFile()
The Non Standard Get File is an example of a modification of the Get File Dialog. This routine should be used in applications that can open 2 or more different types of documents. NSGetFile displays a Get File dialog that contains, along with the normal features, a Popup menu that indicates what file types the routine is currently viewing. The default setting is all documents; all documents of the types passed to the routine will be shown in the dialog. However, the user can select the Popup menu and change the settings so that only 1 type can be viewed.
NSGetFile is passed 4 input parameters (string thePrompt, integer theNumTypes, pointers theTypeListPtr and theNameListPtr) and passes back 4 output parameters (Boolean theGood, integer theRefNum, string theFileName, OStype theType).
This routine is written slightly differently than the NSPutFile procedures. NSGetFile was written so that there is no upper limit to the number of different file types that can be viewed by the dialog. Instead of passing the individual file types and file type name as parameters to the routine, all the file types and all the file names are stored in an array before NSGetFile is called. Then pointers to these two arrays are passed to NSGetFile as parameters. TheNumTypes parameter is the number of different file types the routine can display in the dialog. ThePrompt is the prompt that is displayed on the dialog.
If the user selects a file, theGood is returned TRUE. In this case, theRefNum contains the volume reference number, theFileName contains the files name, and theType returns the files OStype. If the user selects cancel, theGood returns FALSE.
Just as SFPPutfile ROM call is an variation of the SFPutfile call, there is a SFPGetFile ROM call that provides expanded functionality in comparison to the normal SFGetFile call. In NSGetFile, the SFPGetFile call is passed the ID number of a Dialog template resource and Dialog item list resource that is almost identical to the standard SFGetFile resources (stored at ID -4000). The modified resources contain a text item (for the prompt) and an UserItem (for the Popup menu). The SFPGetFile call is also passed a Dialog hook routine, NSGetDlg. As in the previous examples, the first thing NSGetDlg does is set the prompt and set the UserItem to the NSPopUpItem procedure. NSPopUpItem displays the graphics for a Popup menu. NSGetDlg also takes care of handling the Popup (using call to PopUpMenuSelect) when a user selects the item. The SFPGetFile call is also passed a File Filter routine, NSGetFileFilter. NSGetFileFilter decides which files are displayed in the dialog. Depending on the setting of the Popup menu, the routine either allows only a single type of file to be viewed, or it allows all the types of files it knows about to be viewed. Notice that if a user selects a new setting on the Popup menu, NSGetDlg sets the event item number to 101. This tells the SFPGetFile ROM call to redraw the dialog from scratch, which it does using the NGSGetFileFilter (possibly displaying a new group of files).
Beyond
Hopefully these routines should be easy to modify for your own use. NSIconPutFile could be rewritten to handle more than 4 file types. NSGetFile could be modified to use a simpler parameter method when you know exactly which file types your program can open. NSGetFile could also be modified to use icons instead of a Popup menu. The application I wrote NSGetFile for could read a variable number of file types (depending on configuration of program) that had no upper limits.
All routines could be rewritten so as not to use so much global parameter data. Instead, the global type of data could be stored in a temporary handle. As the start of the routine, the handle is allocated, and the values plugged in. Then this handle is stored in the reference value of the dialog (remember a dialog is a window). This is a location that all the dlogHook, fileFilter and UserItem routines can access. Just before the main routine is done, the handle can be disposed of.
While this method does use less global space, for simplicity and ease of understanding, I stuck with global variables. If you were to use the routine with something that does not have global variables (FKEYs, Drivers, DAs), you might have to use that method.
If anyone comes up with other interesting user interfaces, I would love to see them. I can be contacted on Applelink (SHEETS1) or America Online (Mage Steve).
