tixScrolledWindow: Create and manipulate Tix ScrolledWindow widgets

NAME

tixScrolledWindow - Create and manipulate Tix ScrolledWindow widgets

SYNOPSIS

tixScrolledWindow pathName ?options? -anchor    -background     -cursor
-relief -borderWidth

WIDGET-SPECIFIC OPTIONS

[ -height height Height ] Specifies the desired height for the window, in pixels. [ -scrollbar scrollbar Scrollbar ] Specifies the display policy of the scrollbars. The following values are recognized:

auto ?+x? ?-x? ?+y? ?-y?

When -scrollbar is set to "auto", the scrollbars are shown only when needed. Additional modifiers can be used to force a scrollbar to be shown or hidden. For example, "auto -y" means the horizontal scrollbar should be shown when needed but the vertical scrollbar should always be hidden; "auto +x" means the vertical scrollbar should be shown when needed but the horizontal scrollbar should always be shown, and so on.

both

Both scrollbars are shown

none

The scrollbars are never shown.

x

Only the horizontal scrollbar is shown;

y

Only the vertical scrollbar is shown.

[ -width width Width ] Specifies the desired width for the window, in pixels. [ -xscrollincrement xScrollIncrement ScrollIncrement ] Specifies by how much the window should be scrolled in the horizontal direction when the user presses the arrows in the horizontal scrollbar. In Pixels. [ -yscrollincrement yScrollIncrement ScrollIncrement ] Specifies by how much the window should be scrolled in the vertical direction when the user presses the arrows in the horizontal scrollbar. In pixels.

SUBWIDGETS

Name:           hsb
Class:          Scrollbar

The horizontal scrollbar subwidget.

Name:           window
Class:          Frame

The frame subwidget which is scrolled by the ScrolledWindow widget.

Name:           vsb
Class:          Scrollbar

The vertical scrollbar subwidget.

DESCRIPTION

The tixScrolledWindow command creates a new window (given by the pathName 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 ScrolledWindow 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 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 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.
