Please note that this code is very nice if you're programming for Mac OS 7.x - 9.x. If you're doing programming for Mac OS X, there are much more modern solutions that Apple provides for you to use. This archive contains the code for a control that looks like the System 7 standard window zoom box, although the CDEF will use the Appearance Manager (version 1.1 or higher) to draw the theme specific zoom button if the Appearance Manager is installed. ZoomBox CDEF is source code that you compile separately and add to your project. The code for zooming is, by definition, application specific so none of that is done here. This CDEF is basically a button that looks like a window zoom box. There is also a function to create a |
Using the ZoomBox CDEF
- Add the relevant files to your project.
- For Carbon targets: Add the ZoomBox.c file to your project.
- For non-Carbon targets: Copy the CDEFs from ZoomBoxCDEF.rsrc or ZoomBox CDEF to your project.
- Create a control that uses it.
- For Carbon targets: Call
CreateCustomControlwith the UPP from theNewZoomBoxCDEFUPPfunction. - For non-Carbon targets: Call
NewControlwith a procID of 2064 for PPC and 2048 for 68K (unless you renumber the CDEF resources).
- For Carbon targets: Call
- When the control is clicked and
TrackControlreturns the same part number asFindControl(which should bekControlButtonPart), do your zooming behavior.
Wish List
The following are some of the things I'd like to see implemented.
- Get code for drawing the Platinum window zoom box (without Appearance Manager) working correctly under 68K. Currently, it draws in wonky colors instead of all those grays. I tried allocating a color table, but that didn't seem to do the trick. Perhaps the position of black and white was affecting it.
- Add selectors for other operating system zoom boxes: BeOS, Windows, etc.
- Figure out how to make a FAT (includes PPC and 68K code) CDEF.
Note: These things will probably never get done because I don't program for Mac OS 7.x - 9.x anymore.
Downloads
ZoomBoxCDEF.hqx - Binhexed self-extracting archive (246K) - contains Codewarrior 11, Codewarrior Pro 4, Pro 5 and Pro 6 projects, source code, and the compiled CDEFs for 68K and PPC.
Acknowledgments
All the people who've written CDEFs and posted the source code.
Thanks to Brian S. Hall for the code to draw the Platinum zoom box without the Appearance Manager.
