SET INPUT FOCUS

OpenVMS Format

Argument Information
Argument Usage Data Type Access Mechanism
display identifier uns longword read reference
focus_id identifier uns longword read reference
revert_to longword longword read reference
time longword uns longword read reference

Arguments

focus_id

The window identifier of the window in which you want to set the input focus.

The identifier of the window was originally returned by CREATE SIMPLE WINDOW or CREATE WINDOW. When the window identifier is specified, that window becomes the keyboard's focus window. When keyboard events are normally reported to this window (or its inferiors), the events continue to be reported. Otherwise, the event is reported with respect to the focus window.

One of the following predefined values can be specified instead of the window identifier:

X$C_POINTER_ROOT
X$C_NONE

revert_to

Where the input focus moves to when the focus window becomes unviewable.

One of the following predefined values can be specified:

X$C_REVERT_TO_PARENT
X$C_REVERT_TO_POINTER_ROOT
X$C_REVERT_TO_NONE
