NAME

Tk::Toplevel - Create and manipulate Toplevel widgets

CONTENTS

SYNOPSIS

$toplevel = $parent-><B>ToplevelB>(?options?);

STANDARD OPTIONS

<B>-borderwidthB>        <B>-highlightbackgroundB>        <B>-highlightthicknessB> <B>-takefocusB> <B>-classB>      <B>-highlightcolorB>     <B>-reliefB> <B>-cursorB>

See Tk::options for details of the standard options.

WIDGET-SPECIFIC OPTIONS

Name:  <B>backgroundB>
Class: <B>BackgroundB>
Switch:        <B>-backgroundB> This option is the same as the standard <B>backgroundB> 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:  <B>colormapB>
Class: <B>ColormapB>
Switch:        <B>-colormapB> Specifies a colormap to use for the window. The value may be either <B>newB>, 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 <B>colormapB> option is not specified, the new window uses the default colormap of its screen. This option may not be changed with the <B>configureB> method.
Name:  <B>containerB>
Class: <B>ContainerB>
Switch:        <B>-containerB> 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 <B>-useB> 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 <B>configureB> method.
Name:  <B>heightB>
Class: <B>HeightB>
Switch:        <B>-heightB> Specifies the desired height for the window in any of the forms acceptable to <B>Tk_GetPixelsB>. If this option is less than or equal to zero then the window will not request any size at all.
Name:  <B>menuB>
Class: <B>MenuB>
Switch:        <B>-menuB> 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:  <B>‘‘’’B>
Class: <B>‘‘’’B>
Switch:        <B>-screenB> 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 <B>configureB> method.
Switch:        <B>-titleB> Specifies the title of the toplevel window.
Name:  <B>useB>
Class: <B>UseB>
Switch:        <B>-useB> 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 <B>winfo idB> 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 <B>-containerB> option was specified. This option may not be changed with the <B>configureB> method.
Name:  <B>visualB>
Class: <B>VisualB>
Switch:        <B>-visualB> Specifies visual information for the new window in any of the forms accepted by <B>Tk_GetVisualB>. If this option is not specified, the new window will use the default visual for its screen. The <B>visualB> option may not be modified with the <B>configureB> method.
Name:  <B>widthB>
Class: <B>WidthB>
Switch:        <B>-widthB> Specifies the desired width for the window in any of the forms acceptable to <B>Tk_GetPixelsB>. If this option is less than or equal to zero then the window will not request any size at all.

DESCRIPTION

The <B>ToplevelB> 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 <B>toplevelB> 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 <B>ToplevelB> method creates a widget object. This object supports the <B>configureB> and <B>cgetB> 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.
