0 indicates the beginning, -and 1 indicates the end. -The first fraction indicates the first information in the widget -that is visible in the window, and the second fraction indicates -the information just after the last portion that is visible. -.PP -Typically the \fB\-xscrollcommand\fR option consists of the path name -of a \fBscrollbar\fR widget followed by -.QW set , -e.g. -.QW ".x.scrollbar set" . -This will cause the scrollbar to be updated whenever the view in the -window changes. -.PP -If this option is set to the empty string (the default), -then no command will be executed. -.RE -.OP \-yscrollcommand yScrollCommand ScrollCommand -A command prefix, used to communicate with vertical scrollbars. -See the description of \fB\-xscrollcommand\fR above for details. -.SH "LABEL OPTIONS" -The following options are supported by labels, buttons, -and other button-like widgets: -.OP \-compound compound Compound -Specifies how to display the image relative to the text, -in the case both \fB\-text\fR and \fB\-image\fR are present. -Valid values are: -.RS -.IP text -Display text only. -.IP image -Display image only. -.IP center -Display text centered on top of image. -.IP top -.IP bottom -.IP left -.IP right -Display image above, below, left of, or right of the text, respectively. -.IP none -The default;

-a list of two numbers specify the horizontal and the vertical padding; -a single number specifies the same padding all the way around the widget. -.OP \-text text Text -Specifies a text string to be displayed inside the widget -(unless overridden by \fB\-textvariable\fR). -.OP \-textvariable textVariable Variable -Specifies the name of a global variable whose value will be used -in place of the \fB\-text\fR resource. -.OP \-underline underline Underline -If set, specifies the integer index (0-based) of a character to underline -in the text string. -The underlined character is used for mnemonic activation. -.OP \-width width Width -If greater than zero, specifies how much space, in character widths, -to allocate for the text label. -If less than zero, specifies a minimum width. -If zero or unspecified, the natural width of the text label is used. -.SH "COMPATIBILITY OPTIONS" -.OP \-state state State -May be set to \fBnormal\fR or \fBdisabled\fR -to control the \fBdisabled\fR state bit. -This is a write-only option: -setting it changes the widget state, -but the \fBstate\fR widget command -does not affect the \fB\-state\fR option. -.SH COMMANDS -.TP -\fIpathName \fBcget \fIoption\fR -. -Returns the current value of the configuration option given -by \fIoption\fR. -.TP -\fIpathName \fBconfigure\fR ?\fIoption\fR? ?\fIvalue option value ...\fR? -. -Query or modify the configuration options of the widget. -If one or more \fIoption\-value\fR pairs are specified, -then the command modifies the given widget option(s) -to have the given value(s);
