Description

The scrolledframe combines the functionallity of scrolling with that  of a typical frame widget to implement a clipable viewing area whose visible  region may be modified with the scroll bars. This enables the contruction  of visually larger areas than which could normally be displayed, containing  a heterogenous mix of other widgets. Options exist which allow full control over which scrollbars are displayed and the method, i.e. statically or dynamically. The frame itself may be accessed by the childsite method and then filled with other widget combinations.

Methods

The iwidgets::scrolledframe command creates a new Tcl command whose name is pathName.  This command may be used to invoke various operations on the widget.  It has the following general form: pathName option ?arg arg ...? Option and the args determine the exact behavior of the command.  The following commands are possible for scrolledframe widgets:

Widget-Specific Methods

pathName cget option

Returns the current value of the configuration option given by option. Option may have any of the values accepted by the iwidgets::scrolledframe command.

pathName childsite

Return the path name of the child site.

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 iwidgets::scrolledframe command.

pathName justify direction

Justifies the frame contents via the scroll bars in one of four directions: left, right, top, or bottom.
