A scale displays a \fIslider\fR that can be moved along over a \fItrough\fR, with the relative position of the slider over the trough indicating the value of the variable. .SO ttk_widget \-class \-cursor \-style \-takefocus .SE .SH "WIDGET-SPECIFIC OPTIONS" .OP \-command command Command Specifies the prefix of a Tcl command to invoke whenever the scale's value is changed via a widget command. The actual command consists of this option followed by a space and a real number indicating the new value of the scale. .OP \-from from From A real value corresponding to the left or top end of the scale. .OP \-length length Length Specifies the desired long dimension of the scale in screen units (i.e. any of the forms acceptable to \fBTk_GetPixels\fR). For vertical scales this is the scale's height; for horizontal scales it is the scale's width. .OP \-orient orient Orient Specifies which orientation whether the widget should be laid out horizontally or vertically. Must be either \fBhorizontal\fR or \fBvertical\fR or an abbreviation of one of these. .OP \-to to To Specifies a real value corresponding to the right or bottom end of the scale. This value may be either less than or greater than the \fBfrom\fR option. .OP \-value value Value Specifies the current floating-point value of the variable. .OP \-variable variable Variable Specifies the name of a global variable to link to the scale. Whenever the value of the variable changes, the scale will update to reflect this value. Whenever the scale is manipulated interactively, the variable will be modified to reflect the scale's new value. .SH "WIDGET COMMAND" .TP \fIpathName \fBcget \fIoption\fR . Returns the current value of the specified \fIoption\fR; see \fIttk::widget(n)\fR. .TP \fIpathName \fBconfigure \fR?\fIoption\fR? ?\fIvalue option value ...\fR? . Modify or query widget options; see \fIttk::widget(n)\fR. .TP \fIpathName \fBget \fR?\fIx y\fR? . Get the current value of the \fB\-value\fR option, or the value corresponding to the coordinates \fIx,y\fR if they are specified. \fIX\fR and \fIy\fR are pixel coordinates relative to the scale widget origin. .TP \fIpathName \fBidentify\fR \fIx y\fR Returns the name of the element at position \fIx\fR, \fIy\fR. See \fIttk::widget(n)\fR. .TP \fIpathName \fBinstate \fIstatespec\fR ?\fIscript\fR? . Test the widget state; see \fIttk::widget(n)\fR. .TP \fIpathName \fBset \fIvalue\fR . Set the value of the widget (i.e. the \fB\-value\fR option) to \fIvalue\fR. The value will be clipped to the range given by the \fB\-from\fR and \fB\-to\fR options. Note that setting the linked variable (i.e. the variable named in the \fB\-variable\fR option) does not cause such clipping. .TP \fIpathName \fBstate\fR ?\fIstateSpec\fR? . Modify or query the widget state; see \fIttk::widget(n)\fR. .SH "INTERNAL COMMANDS" .TP \fIpathName \fBcoords \fR?\fIvalue\fR? . Get the coordinates corresponding to \fIvalue\fR, or the coordinates corresponding to the current value of the \fB\-value\fR option if \fIvalue\fR is omitted. .SH "SEE ALSO" ttk::widget(n), scale(n) .SH KEYWORDS scale, slider, trough, widget .\" Local Variables: .\" mode: nroff .\" fill-column: 78 .\" End:
