Multi-Window Stick Around DA

By Jörge Langowski, MacTutor Editorial Board, Grenoble, France

“Multi-window, multi-menu, permanent desk accessory”

As mentioned in a previous column, we are going to learn some more about creating desk accessories in Forth (Mach2) this time. The simple desk accessory from V3#2 was useful to show the principle of implementing such a thing in Forth, but in real life DA writing there are a number of things that one might have to add to that example. Therefore, I am going to write this time about the implementation of a desk accessory that supports multiple windows and menus; also it will automatically reinstall itself after it has been closed involuntarily (e.g. when calling an application from the Finder).

This article is by no means comprehensive; there have been several articles in our journal on desk accessories implemented in assembler or C (V2#3,4,6), and I’m making use of some of the ideas described therein. So go back to those old issues (if you don’t have them, order them through us) for any further references.

Making a DA permanent

As you’ll certainly have noticed, there are several occasions when desk accessories will be closed automatically by the system. Whenever you start up a new application from the Finder, or quit an application to go back to the Finder, the application heap will be reinitialized and all desk accessories closed. The two other occasions on which your DA will be closed are copying a file under the Finder and ejecting the startup disk.

Sometimes one would like to have a desk accessory (like a clock) stay active permanently, unless one closes it voluntarily. I’ll tell you further down below how that can be accomplished; however notice that in such a case one would always have to check whether the close box has really been clicked when the DA’s Close routine is called. This is not so easy... since the system handles part of the mouse-down events for a DA automatically before we could even intercept them. Particularly, a mouse-down in the drag region will let the window be dragged around and a click in the Close box will generally cause the Close routine to be called.

So our first problem would be to distinguish a voluntary close from an involuntary one. One easy way to do this is to create the window without a close box and let the user click a button inside it, or select some menu option, to notify the DA that we don’t want it any more. The control - or menu - handling routine would then by itself call CloseDeskAcc but set a flag that indicates to the close routine that we really want to close the window. The close routine then had a way to distinguish voluntary from involuntary close through the flag.

Fig. 1 DA sticks around between applications

There is, however, a more elegant way to go. As was already pointed out by David Dunham in V2#6, there is a system global (undocumented in IM) called CloseOrnHook ($A88). If this location contains a non-NIL pointer, the system assumes that it is the address of a routine that should be called when the close box of a desk accessory window is clicked (instead of calling its Close routine). So all we have to do is to install a pointer to our own Close routine here every time the desk accessory window is activated and remove it when it is deactivated (so that other DAs may be closed correctly). The custom Close routine would then set the flag mentioned above and call CloseDeskAcc with the driver ID number of our DA.

Hooking into SystemTask

Now that our Close routine knows whether we really wanted to call it or not, how do we go about making the desk accessory permanent? After all, the heap will be cleaned on starting up an application, and we won’t be able to keep our DA in the application heap even if we wanted. Even if we put it into the system heap instead, it will stay there - eating up memory - but receive no more system calls, so it will be unusable.

Here a clever trick comes in that I again got to know on one of our developer’s club meetings (idea by L. de Bersuder): Since every application will call SystemTask pretty soon after having been started up, just install a patch (located in the system heap) to the SystemTask routine that reopens the desk accessory, then resets the old SystemTask trap address and thereafter removes itself from the system heap. This method, of course, will work for one such permanent DA at a time only, but provides a good starting point from which on one can do further experimentation.

It is time, now, to look at the program. Listing 1 just contains general Forth definitions that are necessary for the program (and haven’t changed much compared to the V3#2 column). Listing 3 is the RMaker input for generating the desk accessory, and Listing 2 is our example.

The code for the SystemTask intercept routine is at the beginning of the listing. The actual intercept routine does nothing but check whether there is a dialog present in front (in case our DA will set up a dialog as well, this can lead to conflicts), and if that is not the case, restores the old trap address for SystemTask, then opens the desk accessory, using a built-in name string. If you change the name of the accessory, you would have to change this string accordingly. The intercept routine is called by a glue routine which saves the registers and sets up a local A6 stack for the Forth code (our usual method); then the Forth code is entered. The Forth word write-out writes the code for the patch routine to a PROC resource (marked locked, in system heap, and with an ID of -16000, so that it belongs to the desk accessory).

Installation of the SystemTask patch is performed in the Close routine. Here the flag closeflag is checked; if it is =1, it is assumed that the close was involuntary and the patch is installed by calling install.intercept. The latter routine gets the PROC resource containing the patch code (it will be in the system heap), stores the old trap address of SystemTask in trapaddr in the patch routine and sets the new trap address to the beginning of the intercept routine. The appropriate offsets *trapaddr and *inter have been calculated beforehand at compilation time. This, by the way, is one simple method to reference Forth code from outside routines.

After the installation of the intercept routine, the system is set up to reinstall the desk accessory the next time SystemTask gets a call.

Multiple windows and the custom Close routine

To close the desk accessory for good, we make use of the CloseOrnHook system global. Both windows belonging to the DA carry the driver reference number in their WindowKind fields; so the system would normally handle close box clicks for them. To avoid this, we have to put a non-zero value into CloseOrnHook. Since a) we might want to install a different behavior for the close boxes depending which window is closed, and b) we need a custom close routine anyway to disable the automatic reinstallation, we install a pointer to the realclose routine in CloseOrnHook every time one of the DA windows is activated and reset that location to zero when it is deactivated.

The routine pointed to by CloseOrnHook receives two parameters: the dCtlEntry pointer in A1 and the window pointer in A4. The window pointer is used to determine the action (one window will beep, the other one will close the DA for good when it is closed), and dCtlEntry is needed to determine the DA’s driver reference number so that we can close it.

Multiple Menus

This is only a little more involving than having just a single menu. In order to have the system pass the menu parameters to the DA for one out of several menus, we have to install the DA’s driver reference number in the global MBarEnable ($A20, word). Then, when a window is activated, we get the handle of the current menu bar and save it away, and set up the menu bar using our own list of menus. In our case, I added two menus which will show up when the main window is clicked. When that window is deactivated, we reset the old menu bar from the stored value and set MBarEnable to zero. As long as MBarEnable is <>0, the DA will receive the menu ID in csParam and the menu item number in csParam + 2. This is taken care of in the Ctl routine. Our menu handler again simply displays the names of the items.

Other remarks

The zoom box and grow box are handled differently in this DA than they were in my first example (I briefly mentioned this in the March column). When a mouse down event is detected, we set the windowKind field of the window record to 8 (application-created window) before calling FindWindow again, this time receiving the correct part code from FindWindow. The windowKind is reset to the old value thereafter, so that close box and drag region clicks will again be handled correctly by the system.

Knowing the zoom box or grow box part code, we can then go and take the appropriate actions.

Just for fun, I added a button in the main (resizeable) window which will show or hide the other window. That window displays the time.

Happy threading and see you next month.
