hidden; "auto +x" means the vertical scrollbar should be
shown when needed but the horizontal scrollbar should

DESCRIPTION
The tixScrolledWindow command creates a new window (given by the path-
Name argument) and makes it into a ScrolledWindow widget. Additional
options, described above, may be specified on the command line or in
the option database to configure aspects of the ScrolledWindow widget
such as its cursor and relief.
CREATING WIDGETS INSIDE A SCROLLEDWINDOW WIDGET
To create widgets inside a ScrolledWindow widget, one must create the
new widgets relative to the window subwidget and manage them inside the
window subwidget. An error will be generated if one tries to create
widgets as immediate children of the ScrolledWindow. For example: the
following is correct code, which creates new widgets inside the window
subwidget:
tixScrolledWindow .w; pack .w
set f [.w subwidget window]
button $f.b -text hi -width 40 -height 40
pack $f.b
The following example code is incorrect because it tries to create
immediate children of the ScrolledWindow .w:
tixScrolledWindow .w; pack .w
button .w.b -text hi -width 40 -height 40
pack .w.b
WIDGET COMMANDS
The tixScrolledWindow command creates a new Tcl command whose name is
the same as the path name of the ScrolledWindow widget's window. This
command may be used to invoke various operations on the widget. It has
the following general form:
pathName option ?arg arg ...?
PathName is the name of the command, which is the same as the Scrolled-
Window widget's path name. Option and the args determine the exact
behavior of the command. The following commands are possible for
ScrolledWindow widgets:
pathName cget option
Returns the current value of the configuration option given by
option. Option may have any of the values accepted by the
tixScrolledWindow command.
pathName configure ?option? ?value option value ...?
Query or modify the configuration options of the widget. If no
option is specified, returns a list describing all of the avail-
able options for pathName (see Tk_ConfigureInfo for information
on the format of this list). If option is specified with no
value, then the command returns a list describing the one named
option (this list will be identical to the corresponding sublist
of the value returned if no option is specified). If one or
more option-value pairs are specified, then the command modifies
the given widget option(s) to have the given value(s); in this
case the command returns an empty string. Option may have any
of the values accepted by the tixScrolledWindow command.
pathName subwidget name ?args?
When no additional arguments are given, returns the pathname of
the subwidget of the specified name.
When no additional arguments are given, the widget command of
the specified subwidget will be called with these parameters.
