This argument is not used by the default processing methods. However, it passes the ID of the container window in case a method you supply needs this information. (n)
This argument is not used by the default processing methods. However, it passes one of the following (defined in tools.def) in case a method you supply needs this: DC_LIST for a standard Toolkit list or an ActiveX Toolkit list, or DC_WINDOW for a Toolkit window. (n)
The ID for the child container window. (n)
The reason the child was activated, which can be blank (indicating that the child was already activated), a program‑supplied reason passed because the child was activated programmatically, or one of the following: (a)
C_FIRST = Focus moved in attempt to reach first child.
C_LAST = Focus moved in attempt to reach last child.
C_NEXT = Focus moved from previous child (e.g., tab).
C_PREV = Focus moved from next child (e.g., shift+tab).
C_SET = Child explicitly activated. For example, this could be the result of a mouse click, or it could be that the child was activated programmatically without a specified reason.
(optional) This argument is not used by the default method C_METHCTR. However, this argument passes a copy of the a_methoddata argument specified by recordindex (a DC_ADD argument) for other methods that need this information. (a)
a_methoddata1 through a_methoddata20
(optional) Up to 20 additional data arguments. (any)
C_METHCTR is a Toolkit‑supplied processing method that C_PROCESS calls by default when processing a child window that is itself a composite window. If you want something other than the default processing described below, you can instruct C_PROCESS to call a different routine by passing the routine’s name in the DC_ADD call for the child composite window.
C_METHCTR does the following:
|1.||Establishes focus in the child composite window by calling the DC_CTRCONTEXT subfunction of %C_CONTAINER and passing the ID of the child container and reason.|
|2.||Calls C_PROCESS to process the child composite window, passing the ID of the composite container window and the a_methoddata arguments.|
To view the code for this method, see the ctrmeths.dbl file included in your UI Toolkit distribution. This file is distributed simply as a reference and a starting point for writing your own composite window processing methods; modifying or compiling this file will not change the default methods.
