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.
- Class: 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.
- 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.
