Arguments

container_id

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)

type

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)

child_id

The ID for the child text window. (n)

reason

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.

record

(optional) This argument is not used by the default method C_METHTXT. 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) These arguments are not used by the default method C_METHTXT. However, up to 20 additional data arguments are passed for other methods that need this information. (any)

Discussion

C_METHTXT is a Toolkit-supplied processing method that C_PROCESS calls by default when processing a child text 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 text window.

C_METHTXT does the following:

Calls U_CTRCONTEXT to set context within the selection window.

Calls T_EDIT for the window.
