Instructions
The project files in this package are designed for Metrowerks® CodeWarrior™ IDE. To compile the source code for the ComboBox external area, create a Mac4DX folder in the same folder as your project files. Then make the projects in the following order:
ComboBox-PPC.µ
ComboBox-68K.µ
ComboBoxList-68K.µ
ComboBox-PPC is the PowerMacintosh version of the ComboBox external area. The executable code is put into the data fork, and is used as a Disk Fragment. The data fork contains the PowerPC code for both the main process and the $ComboBoxList process. This project creates a file named ComboBox.Lib in the Mac4DX folder you create in your project folder.
ComboBox-68K is the 68K version of the ComboBox external area main process. The executable code is put into a '4DPX' resource, and is used as a code resource. This resource contains the 68K code for the main process only. The '4DPX' resource is merged into the ComboBox.Lib file created by ComboBox-PPC.µ.
ComboBoxList-68K is the 68K version of the $ComboBoxList process. The executable code is put into a 'CBlp' (ComboBox list process) resource. A pointer to this resource is passed in the kEX_NEW_PROCESS callback to 4D when executing on a 68K machine. The PowerPC equivalent of this code resource is contained in the data fork created by the ComboBox-PPC.µ project file. The 'CBlp' resource is merged into the ComboBox.Lib file.
Important
ComboBox was created using an alpha-level release of the Platform-Independent Extensions Authoring Kit from ACI US. To compile ComboBox, you will need to obtain this authoring kit.
Acknowlegements
The behavior of the ComboBox external area package is based in part on the combo box from Microsoft® Windows™ and the AppleDirections articles “The Joys of Disambiguating,” March 1995, pp. 14-15, and “The Joys of Disambiguating, Part Two,” April 1995, pp. 14-16, by Peter Bickford.
Thanks also to the members of the 4D list on the internet. To subscribe to the 4D list, send email to 4d-nug@liststar.fsti.com with the word “subscribe” in the subject of your message.
Most importantly, thanks to Jesus Christ for answering many “I’m stuck, Lord; please show me how to do this!” prayers, and for guiding me to the resources I needed to find the answers.
