This includes options to control which scrollbars are displayed and the method, i.e. statically or dynamically. .SH "METHODS" .PP The \fBiwidgets::scrolledcanvas\fR command creates a new Tcl command whose name is \fIpathName\fR. This command may be used to invoke various operations on the widget. It has the following general form: .DS C \fIpathName option \fR?\fIarg arg ...\fR? .DE \fIOption\fR and the \fIarg\fRs determine the exact behavior of the command. The following commands are possible for scrolledcanvas widgets: .SH "ASSOCIATED METHODS" .LP .nf .ta 4c 8c 12c \fBaddtag\fR \fBbbox\fR \fBbind\fR \fBcanvasx\fR \fBcanvasy\fB \fBcoords\fR \fBcreate\fR \fBdchars\fR \fBdelete\fR \fBdtag\fR \fBfind\fR \fBfocus\fR \fBgettags\fR \fBicursor\fR \fBindex\fR \fBinsert\fR \fBitemconfigure\fR \fBlower\fR \fBmove\fR \fBpostscript\fR \fBraise\fR \fBscale\fR \fBscan\fR \fBselect\fR \fBtype\fR \fBxview\fR \fByview\fR .fi .LP See the "canvas" manual entry for details on the associated methods. .SH "WIDGET-SPECIFIC METHODS" .TP \fIpathName \fBcget\fR \fIoption\fR Returns the current value of the configuration option given by \fIoption\fR. \fIOption\fR may have any of the values accepted by the \fBiwidgets::scrolledcanvas\fR command. .TP \fIpathName \fBchildsite\fR Returns the child site widget path name. .TP \fIpathName\fR \fBconfigure\fR ?\fIoption\fR? ?\fIvalue option value ...\fR? Query or modify the configuration options of the widget. If no \fIoption\fR is specified, returns a list describing all of the available options for \fIpathName\fR (see \fBTk_ConfigureInfo\fR for information on the format of this list). If \fIoption\fR is specified with no \fIvalue\fR, 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 \fIoption\fR is specified). 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); in this case the command returns an empty string. \fIOption\fR may have any of the values accepted by the \fBiwidgets::scrolledcanvas\fR command. .TP \fIpathName \fBjustify \fIdirection\fR Justifies the canvas contents via the scroll bars in one of four directions: \fBleft\fR, \fBright\fR, \fBtop\fR, or \fBbottom\fR. .SH "COMPONENTS" .LP .nf Name: \fBcanvas\fR Class: \fBCanvas\fR .fi .IP The canvas component is the canvas widget. See the "canvas" widget manual entry for details on the canvas component item. .LP .nf Name: \fBhorizsb\fR Class: \fBScrollbar\fR .fi .IP The horizsb component is the horizontal scroll bar. See the "ScrollBar" widget manual entry for details on the horizsb component item. .LP .nf Name: \fBvertsb\fR Class: \fBScrollbar\fR .fi .IP The vertsb component is the vertical scroll bar.
