NAME toplevel - Create and manipulate toplevel widgets SYNOPSIS toplevel pathName ?options? STANDARD OPTIONS borderWidth highlightBackground highlightThickness takeFocus | cursor highlightColor relief See the ``options'' manual entry for details on the standard options. WIDGET-SPECIFIC OPTIONS Name: background | Class: Background | Command-Line Switch:-background | This option is the same as the standard background option except | that its value may also be specified as an empty string. 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: class | Class: Class | Command-Line Switch:-class | Specifies a class for the window. This class will be used when | querying the option database for the window's other options, and it | will also be used later for other purposes such as bindings. The | class option may not be changed with the configure widget command. Name: colormap Class: Colormap Command-Line 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 pathName), 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 widget command. Name: height Class: Height Command-Line 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: None | Class: None | Command-Line 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 widget command. Name: visual | Class: Visual | Command-Line 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 widget command. Name: width Class: Width Command-Line 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 command creates a new toplevel widget (given by the pathName 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 COMMAND The toplevel command creates a new Tcl command whose name is the same as the path name of the toplevel'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 toplevel widget's path name. Option and the args determine the exact behavior of the command. The following commands are possible for toplevel 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 toplevel | 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 available 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 toplevel command. BINDINGS When a new toplevel is created, it has no default event bindings: toplevels are not intended to be interactive.
