NAME
Tk::Toplevel - Create and manipulate Toplevel widgets
SYNOPSIS
$toplevel = $parent->Toplevel(?options?);
STANDARD OPTIONS
-borderwidth -highlightbackground -highlightthickness -takefocus
-class -highlightcolor -relief -cursor
See Tk::options for details of the standard options.
WIDGET-SPECIFIC OPTIONS
Name: background
Class: Background
Switch: -background
This option is the same as the standard background option except
that its value may also be specified as an undefined value. In
this case, the widget will display no background or border, and no
colors will be consumed from its colormap for its background and
border.
Name: colormap
Class: Colormap
Switch: -colormap
Specifies a colormap to use for the window. The value may be
either new, in which case a new colormap is created for the window
and its children, or the name of another window (which must be on
the same screen and have the same visual as $widget), in which case
the new window will use the colormap from the specified window. If
the colormap option is not specified, the new window uses the
default colormap of its screen. This option may not be changed
with the configure method.
Name: container
Class: Container
Switch: -container
The value must be a boolean. If true, it means that this window
will be used as a container in which some other application will be
embedded (for example, a Tk toplevel can be embedded using the -use
option). The window will support the appropriate window manager
protocols for things like geometry requests. The window should not
have any children of its own in this application. This option may
not be changed with the configure method.
Name: height
Class: Height
Switch: -height
Specifies the desired height for the window in any of the forms
acceptable to Tk_GetPixels. If this option is less than or equal
to zero then the window will not request any size at all.
Name: menu
Class: Menu
Switch: -menu
Specifies a menu widget to be used as a menubar. On the Macintosh,
the menubar will be displayed accross the top of the main monitor.
On Microsoft Windows and all UNIX platforms, the menu will appear
accross the toplevel window as part of the window dressing
maintained by the window manager.
Name: ""
Class: ""
Switch: -screen
Specifies the screen on which to place the new window. Any valid
screen name may be used, even one associated with a different
display. Defaults to the same screen as its parent. This option
is special in that it may not be specified via the option database,
and it may not be modified with the configure method.
Switch: -title
Specifies the title of the toplevel window.
Name: use
Class: Use
Switch: -use
This option is used for embedding. If the value isn't an empty
string, it must be the the window identifier of a container window,
specified as a hexadecimal string like the ones returned by the
winfo id command. The toplevel widget will be created as a child of
the given container instead of the root window for the screen. If
the container window is in a Tk application, it must be a frame or
toplevel widget for which the -container option was specified.
This option may not be changed with the configure method.
Name: visual
Class: Visual
Switch: -visual
Specifies visual information for the new window in any of the forms
accepted by Tk_GetVisual. If this option is not specified, the new
window will use the default visual for its screen. The visual
option may not be modified with the configure method.
Name: width
Class: Width
Switch: -width
Specifies the desired width for the window in any of the forms
acceptable to Tk_GetPixels. If this option is less than or equal
to zero then the window will not request any size at all.
DESCRIPTION
The Toplevel method creates a new toplevel widget (given by the $widget
argument). Additional options, described above, may be specified on
the command line or in the option database to configure aspects of the
toplevel such as its background color and relief. The toplevel command
returns the path name of the new window.
A toplevel is similar to a frame except that it is created as a top-
level window: its X parent is the root window of a screen rather than
the logical parent from its path name. The primary purpose of a
toplevel is to serve as a container for dialog boxes and other
collections of widgets. The only visible features of a toplevel are
its background color and an optional 3-D border to make the toplevel
appear raised or sunken.
WIDGET METHODS
The Toplevel method creates a widget object. This object supports the
configure and cget methods described in Tk::options which can be used
to enquire and modify the options described above. The widget also
inherits all the methods provided by the generic Tk::Widget class, and
the Tk::Wm class.
BINDINGS
When a new toplevel is created, it has no default event bindings:
toplevels are not intended to be interactive.
