Widget-Specific Options

Name:height
Class:Height
Command-Line Switch:-height
Specifies the height of the scrolled text as an entire unit. The value may be specified in any of the forms acceptable to Tk_GetPixels. Any additional space needed to display the other components such as labels, margins, and scrollbars force the text to be compressed. A value of zero along with the same value for the width causes the value given for the visibleitems option to be applied which administers geometry constraints in a different manner. The default height is zero.
Name:hscrollMode
Class:ScrollMode
Command-Line Switch:-hscrollmode
Specifies the the display mode to be used for the horizontal scrollbar: static, dynamic, or none. In static mode, the scroll bar is displayed at all times. Dynamic mode displays the scroll bar as required, and none disables the scroll bar display. The default is static.
Name:sbWidth
Class:Width
Command-Line Switch:-sbwidth
Specifies the width of the scrollbar in any of the forms acceptable to Tk_GetPixels.
Name:scrollMargin
Class:Margin
Command-Line Switch:-scrollmargin
Specifies the distance between the text area and scrollbar in any of the forms acceptable to Tk_GetPixels. The default is 3 pixels.
Name:textBackground
Class:Background
Command-Line Switch:-textbackground
Specifies the background color for the text area in any of the forms acceptable to Tk_GetColor.
Name:textFont
Class:Font
Command-Line Switch:-textfont
Specifies the font to be used in the scrolled text area.
Name:visibleitems
Class:VisibleItems
Command-Line Switch:-visibleitems
Specifies the widthxheight in characters and lines for the text. This option is only administered if the width and height options are both set to zero, otherwise they take precedence. The default value is 80x24. With the visibleitems option engaged, geometry constraints are maintained only on the text. The size of the other components such as labels, margins, and scroll bars, are additive and independent, effecting the overall size of the scrolled text. In contrast, should the width and height options have non zero values, they are applied to the scrolled text as a whole. The text is compressed or expanded to maintain the geometry constraints.
Name:vscrollMode
Class:ScrollMode
Command-Line Switch:-vscrollmode
Specifies the the display mode to be used for the vertical scrollbar: static, dynamic, or none. In static mode, the scroll bar is displayed at all times. Dynamic mode displays the scroll bar as required, and none disables the scroll bar display. The default is static.
Name:width
Class:Width
Command-Line Switch:-width
Specifies the width of the scrolled text as an entire unit. The value may be specified in any of the forms acceptable to Tk_GetPixels. Any additional space needed to display the other components such as labels, margins, and scrollbars force the text to be compressed. A value of zero along with the same value for the height causes the value given for the visibleitems option to be applied which administers geometry constraints in a different manner. The default width is zero.

Description

The iwidgets::scrolledtext command creates a scrolled text widget with additional options to manage the scrollbars. This includes options to control the method in which the scrollbars are displayed, i.e. statically or dynamically. Options also exist for adding a label to the scrolled text area and controlling its position. Import/export of methods are provided for file I/O.

Methods

The iwidgets::scrolledtext 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 scrolledtext 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::scrolledtext command.
pathName childsite
Returns the child site widget path name.
pathName clear
Clear the text area of all characters.
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::scrolledtext command.
pathName import filename ?index?
Load the text from a file into the text area at the index. The filename must exist.
pathName export filename
Write text to a file. If filename exists then contents are replaced with text widget contents.
