Listbox in a Dialog

By Robert B. Denny

I have often wanted to have the ability to put up a dialog box like that of “Standard File”, where the user could select from a list of strings.

Implementing such a function requires a combination of most of the Macintosh technology we have covered in the past several months, plus the services of the Dialog Manager. And not just the usual dialog services, we’ll need to implement a filter function to manage the selection box and scroll bar(s) within the dialog.

This month’s C Workshop makes up for past columns which showed relatively few C programming examples. Instead of explaining the theory of using the dialog manager and it’s filter function hooks, I am instead submitting a complete C function that can be used with most compilers which implements a single- selection dialog similar to that of Standard File.

The appearance of the dialog is completely controlled by resource data, including the dimensions of the selection box. Scroll bars are provided in both vertical and horizontal axes, and automatically size to the selection box dimensions. This particular example was used in a utility to perform name lookups on AppleTalk using the Name Binding Protocol (NBP), and allow selection of a particular object by name.

To use the function sel_dialog(), call it with 3 arguments: a “call-back” function name (explained below) and the address and size of a buffer to receive a copy of the selected string. Four buttons control its operation.

“Lookup” causes the “call-back” function to be called repeatedly for pointers to P-strings to put into the selection window. This action continues until the call-back function returns NULL. The strings do not have to be kept around after being passed to sel_dialog(), they are stored in the TERec’s linear text array. The Lookup button may be pressed repeatedly for many fill-in cycles.

If any of the strings are too long to fit in the selection box horizontally, the horizontal scroller is turned on and ranged for the longest string. It con- tinues to be ranged for the longest string as additional strings are added there- after. Likewise, the vertical scroller is turned on and continually ranged if there are more strings than will fit vertically in the selection box.

After a lookup cycle, the strings in the selector box are armed for mouse clicks and are highlighted when clicked. If any strings are highlighted, the “Accept” button is turned on.

Pressing “Accept” causes the selected string to be copied into the buffer supplied as an argument. “Cancel” causes sel_dialog() to return with a null string in the caller’s buffer. In either case the dialog and all associated data in memory is released and a return to the caller is made.

“Clear” causes the selector box to be cleared; all strings are erased and the scrollers are reset and turned off. This might be useful in preparation for a new lookup process.

Resources Control Appearance

Sel_dialog() is written to be controlled by a set of resources which completely determine the dialog’s layout, including the location and titles of the buttons and the location and dimensions of the selection window. The example here is very similar to the dialog used by Standard File, but it needn’t be. Just observe the correlation between the buttons’ DITL item numbers and their functions. Obviously, you can change the code to eliminate buttons, but you can do so as well by “placing” the buttons off- screen without loss of generality of the function.

Here is the RMAKER source for the example shown on the next pages, followed by some pictures of the dialog and the code for sel_dialog(). Note the homebrew ‘RECT’ resource which sets the location and dimensions of the selection box.

By any measure, this is an “advanced” programming example. Little explanation accompanies the code. I highly recommend you review the Dialog Manager section of Inside Macintosh before working through this example. Note how the filter function and modal dialog loops interact to provide the user interface with just a simple function call from the client application.

The dialog box looks like this when it first appears:

If the “Lookup” button is pressed, your routine gets called repeatedly for P-strings to be inserted in the list shown in the window, until it returns NULL. If one of the strings is longer than will fit in the window, the horizontal scroller will be turned on and ranged appropriately, like this:

If your routine returns enough strings to fill up the window vertically, the vertical scroller will be turned on, like this:

After your call-back function has finished, the mouse becomes active and may be used to push buttons and select text. If you click in one of the items in the select window, it will be highlighted and the “Accept” button will be activated like this:

The C code which makes up the rest of this article implements this general purpose selection dialog. Macintosh toolbox calls are italicized for emphasis. The assembly routines use the linkage conventions of Consulair Mac C, and will need minor changes for other C implementations. Other than these differences, the code below should be easy to use under any of the C systems available for the Mac. There are no “library” routines used at all, except those in the Macintosh ROM.
