| .SH DESCRIPTION |
| .PP |
| The \fBiwidgets::scrolledcanvas\fR command creates |
| a scrolled canvas with additional options to manage |
| horizontal and vertical scrollbars. 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 "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. |
