DXmCreateHelpDialog(3X)DXmCreateHelpDialog(3X)NAMEDXmCreateHelpDialog - Creates the Help widget with a dialog box.
SYNOPSIS
Widget DXmCreateHelpDialog(
Widget parent,
char *name,
Arglist arglist,
int argcount );
PARAMETERS
The identifier (widget ID) of the parent widget. The name of the cre‐
ated widget. The application argument list. An integer that repre‐
sents the number of arguments in the application argument list.
DESCRIPTION
The DXmCreateHelpDialog routine creates a help widget that includes its
own dialog box. The help widget is a modeless widget that enables the
application to display appropriate user assistance information in
response to a user request. When the user requests help, the help wid‐
get displays an initial help topic, then gives the user the ability to
view additional help topics.
The DXmNfirstTopic resource allows the application to provide context-
sensitive help by selecting a specific topic based on implicit or
explicit cues from the user.
After the widget has been created, you can change the help topic by
specifying a new DXmNfirstTopic (using the Intrinsic routine XtSetVal‐
ues), and then managing the widget (using the Intrinsic routine XtMan‐
ageChild) to display the help window.
When the user exits from a help session, the widget is automatically
unmanaged.
Resource Information
The help widget does not support children.
You can set the following widget-specific resources in the arglist:
