The composite window processing methods
To process a child window or list, C_PROCESS calls either the default processing method for the child or the processing method assigned to the child when it was added with DC_ADD. The topics listed below document the default Toolkit-supplied processing methods for composite windows and the arguments and return values needed for any processing methods you write for child windows or lists.
You must declare method arguments exactly as documented. Toolkit provides strong prototype validation for composite window processing methods. Incorrectly declared arguments will cause undefined results.
- The C_PROCESS Discussion, which documents how C_PROCESS calls a method and how methods control the C_PROCESS loop by signaling menu entries.
- The ctrmeths.dbl file included in your UI Toolkit distribution. This file includes the code for the default methods and serves as an example of how to create your own composite window processing methods. (Modifying or compiling ctrmeths.dbl will not change the default methods; it is distributed simply to supply examples.)
