| '\" The definitions below are for supplemental macros used in Tcl/Tk |
| '\" manual entries. |
| '\" |
| '\" .AP type name in/out ?indent? |
| '\" Start paragraph describing an argument to a library procedure. |
| '\" type is type of argument (int, etc.), in/out is either "in", "out", |
| '\" or "in/out" to describe whether procedure reads or modifies arg, |
| '\" and indent is equivalent to second arg of .IP (shouldn't ever be |
| '\" needed; use .AS below instead) |
| '\" |
| '\" .AS ?type? ?name? |
| '\" Give maximum sizes of arguments for setting tab stops. Type and |
| '\" name are examples of largest possible arguments that will be passed |
| '\" to .AP later. If args are omitted, default tab stops are used. |
| '\" |
| '\" .BS |
| '\" Start box enclosure. From here until next .BE, everything will be |
| '\" enclosed in one large box. |
| '\" |
| '\" .BE |
| '\" End of box enclosure. |

| '\" Begin code excerpt. |
| '\" |
| '\" .CE |
| '\" End code excerpt. |
| '\" |
| '\" .VS ?version? ?br? |
| '\" Begin vertical sidebar, for use in marking newly-changed parts |
| '\" of man pages. The first argument is ignored and used for recording |
| '\" the version when the .VS was added, so that the sidebars can be |
| '\" found and removed when they reach a certain age. If another argument |
| '\" is present, then a line break is forced before starting the sidebar. |

| '\" options follow on successive lines, in four columns separated |
| '\" by tabs. |
| '\" |
| '\" .SE |
| '\" End of list of standard options for a Tk widget. |
| '\" |
| '\" .OP cmdName dbName dbClass |
| '\" Start of description of a specific option. cmdName gives the |
| '\" option's name as specified in the class command, dbName gives |
| '\" the option's name in the option database, and dbClass gives |
| '\" the option's class in the option database. |

| .BE |
| |
| .SH DESCRIPTION |
| This manual entry describes the common configuration options supported |
| by widgets in the Tk toolkit. Every widget does not necessarily support |
| every option (see the manual entries for individual widgets for a list |
| of the standard options supported by that widget), but if a widget does |
| support an option with one of the names listed below, then the option |
| has exactly the effect described below. |
| .PP |
| In the descriptions below, ``Command-Line Name'' refers to the |
| switch used in class commands and \fBconfigure\fR widget commands to |
| set this value. For example, if an option's command-line switch is |
| \fB\-foreground\fR and there exists a widget \fB.a.b.c\fR, then the |
| command |
| .CS |
| \&\fB.a.b.c\0\0configure\0\0\-foreground black\fR |
| .CE |
| may be used to specify the value \fBblack\fR for the option in the |
| the widget \fB.a.b.c\fR. Command-line switches may be abbreviated, |
| as long as the abbreviation is unambiguous. |
| ``Database Name'' refers to the option's name in the option database (e.g. |
| in .Xdefaults files). ``Database Class'' refers to the option's class value |
| in the option database. |
| .OP \-activebackground activeBackground Foreground |
| Specifies background color to use when drawing active elements. |
| An element (a widget or portion of a widget) is active if the |
| mouse cursor is positioned over the element and pressing a mouse button |
| will cause some action to occur. |
| If strict Motif compliance has been requested by setting the |
| \fBtk_strictMotif\fR variable, this option will normally be |
| ignored; the normal background color will be used instead. |
| .VS |
| For some elements on Windows and Macintosh systems, the active color |
| will only be used while mouse button 1 is pressed over the element. |
| .VE |
| .OP \-activeborderwidth activeBorderWidth BorderWidth |
| Specifies a non-negative value indicating |
| the width of the 3-D border drawn around active elements. See above for |
| definition of active elements. |
| The value may have any of the forms acceptable to \fBTk_GetPixels\fR. |
| This option is typically only available in widgets displaying more |
| than one element at a time (e.g. menus but not buttons). |
| .OP \-activeforeground activeForeground Background |
| Specifies foreground color to use when drawing active elements. |
| See above for definition of active elements. |
| .OP \-anchor anchor Anchor |
| Specifies how the information in a widget (e.g. text or a bitmap) |
| is to be displayed in the widget. |
| Must be one of the values \fBn\fR, \fBne\fR, \fBe\fR, \fBse\fR, |
| \fBs\fR, \fBsw\fR, \fBw\fR, \fBnw\fR, or \fBcenter\fR. |
| For example, \fBnw\fR means display the information such that its |
| top-left corner is at the top-left corner of the widget. |
| .OP "\-background or \-bg" background Background |
| Specifies the normal background color to use when displaying the |
| widget. |
| .OP \-bitmap bitmap Bitmap |
| Specifies a bitmap to display in the widget, in any of the forms |
| acceptable to \fBTk_GetBitmap\fR. |
| The exact way in which the bitmap is displayed may be affected by |
| other options such as \fBanchor\fR or \fBjustify\fR. |
| Typically, if this option is specified then it overrides other |
| options that specify a textual value to display in the widget; |
| the \fBbitmap\fR option may be reset to an empty string to re-enable |
| a text display. |
| In widgets that support both \fBbitmap\fR and \fBimage\fR options, |
| \fBimage\fR will usually override \fBbitmap\fR. |
| .OP "\-borderwidth or \-bd" borderWidth BorderWidth |
| Specifies a non-negative value indicating the width |
| of the 3-D border to draw around the outside of the widget (if such a |
| border is being drawn; the \fBrelief\fR option typically determines |
| this). The value may also be used when drawing 3-D effects in the |
| interior of the widget. |
| The value may have any of the forms acceptable to \fBTk_GetPixels\fR. |
| .OP \-cursor cursor Cursor |
| Specifies the mouse cursor to be used for the widget. |
| The value may have any of the forms acceptable to \fBTk_GetCursor\fR. |
| .OP \-disabledforeground disabledForeground DisabledForeground |
| Specifies foreground color to use when drawing a disabled element. |
| If the option is specified as an empty string (which is typically the |
| case on monochrome displays), disabled elements are drawn with the |
| normal foreground color but they are dimmed by drawing them |
| with a stippled fill pattern. |
| .OP \-exportselection exportSelection ExportSelection |
| Specifies whether or not a selection in the widget should also be |
| the X selection. |
| The value may have any of the forms accepted by \fBTcl_GetBoolean\fR, |
| such as \fBtrue\fR, \fBfalse\fR, \fB0\fR, \fB1\fR, \fByes\fR, or \fBno\fR. |
| If the selection is exported, then selecting in the widget deselects |
| the current X selection, selecting outside the widget deselects any |
| widget selection, and the widget will respond to selection retrieval |
| requests when it has a selection. The default is usually for widgets |
| to export selections. |
| .OP \-font font Font |
| Specifies the font to use when drawing text inside the widget. |
| The value may have any of the forms accepted by \fBTk_GetFont\fR. |
| .OP "\-foreground or \-fg" foreground Foreground |
| Specifies the normal foreground color to use when displaying the widget. |
| .OP \-highlightbackground highlightBackground HighlightBackground |
| Specifies the color to display in the traversal highlight region when |
| the widget does not have the input focus. |
| .OP \-highlightcolor highlightColor HighlightColor |
| Specifies the color to use for the traversal highlight rectangle that is |
| drawn around the widget when it has the input focus. |
| .OP \-highlightthickness highlightThickness HighlightThickness |
| Specifies a non-negative value indicating the width of the highlight |
| rectangle to draw around the outside of the widget when it has the |
| input focus. |
| The value may have any of the forms acceptable to \fBTk_GetPixels\fR. |
| If the value is zero, no focus highlight is drawn around the widget. |
| .OP \-image image Image |
| Specifies an image to display in the widget, which must have been |
| created with the \fBimage create\fR command. |
| Typically, if the \fBimage\fR option is specified then it overrides other |
| options that specify a bitmap or textual value to display in the widget; |
| the \fBimage\fR option may be reset to an empty string to re-enable |
| a bitmap or text display. |
| .OP \-insertbackground insertBackground Foreground |
| Specifies the color to use as background in the area covered by the |
| insertion cursor. This color will normally override either the normal |
| background for the widget (or the selection background if the insertion |
| cursor happens to fall in the selection). |
| .OP \-insertborderwidth insertBorderWidth BorderWidth |
| Specifies a non-negative value indicating the width |
| of the 3-D border to draw around the insertion cursor. |
| The value may have any of the forms acceptable to \fBTk_GetPixels\fR. |
| .OP \-insertofftime insertOffTime OffTime |
| Specifies a non-negative integer value indicating the number of |
| milliseconds the insertion cursor should remain ``off'' in each blink cycle. |
| If this option is zero then the cursor doesn't blink: it is on |
| all the time. |
| .OP \-insertontime insertOnTime OnTime |
| Specifies a non-negative integer value indicating the number of |
| milliseconds the insertion cursor should remain ``on'' in each blink cycle. |
| .OP \-insertwidth insertWidth InsertWidth |
| Specifies a value indicating the total width of the insertion cursor. |
| The value may have any of the forms acceptable to \fBTk_GetPixels\fR. |
| If a border has been specified for the insertion |
| cursor (using the \fBinsertBorderWidth\fR option), the border |
| will be drawn inside the width specified by the \fBinsertWidth\fR |
| option. |
| .OP \-jump jump Jump |
| For widgets with a slider that can be dragged to adjust a value, |
| such as scrollbars, this option determines when |
| notifications are made about changes in the value. |
| The option's value must be a boolean of the form accepted by |
| \fBTcl_GetBoolean\fR. |
| If the value is false, updates are made continuously as the |
| slider is dragged. |
| If the value is true, updates are delayed until the mouse button |
| is released to end the drag; at that point a single notification |
| is made (the value ``jumps'' rather than changing smoothly). |
| .OP \-justify justify Justify |
| When there are multiple lines of text displayed in a widget, this |
| option determines how the lines line up with each other. |
| Must be one of \fBleft\fR, \fBcenter\fR, or \fBright\fR. |
| \fBLeft\fR means that the lines' left edges all line up, \fBcenter\fR |
| means that the lines' centers are aligned, and \fBright\fR means |
| that the lines' right edges line up. |
| .OP \-orient orient Orient |
| For widgets that can lay themselves out with either a horizontal |
| or vertical orientation, such as scrollbars, this option specifies |
| which orientation should be used. Must be either \fBhorizontal\fR |
| or \fBvertical\fR or an abbreviation of one of these. |
| .OP \-padx padX Pad |
| Specifies a non-negative value indicating how much extra space |
| to request for the widget in the X-direction. |
| The value may have any of the forms acceptable to \fBTk_GetPixels\fR. |
| When computing how large a window it needs, the widget will |
| add this amount to the width it would normally need (as determined |
| by the width of the things displayed in the widget); if the geometry |
| manager can satisfy this request, the widget will end up with extra |
| internal space to the left and/or right of what it displays inside. |
| Most widgets only use this option for padding text: if they are |
| displaying a bitmap or image, then they usually ignore padding |
| options. |
| .OP \-pady padY Pad |
| Specifies a non-negative value indicating how much extra space |
| to request for the widget in the Y-direction. |
| The value may have any of the forms acceptable to \fBTk_GetPixels\fR. |
| When computing how large a window it needs, the widget will add |
| this amount to the height it would normally need (as determined by |
| the height of the things displayed in the widget); if the geometry |
| manager can satisfy this request, the widget will end up with extra |
| internal space above and/or below what it displays inside. |
| Most widgets only use this option for padding text: if they are |
| displaying a bitmap or image, then they usually ignore padding |
| options. |
| .OP \-relief relief Relief |
| Specifies the 3-D effect desired for the widget. Acceptable |
| values are \fBraised\fR, \fBsunken\fR, \fBflat\fR, \fBridge\fR, |
| \fBsolid\fR, and \fBgroove\fR. |
| The value |
| indicates how the interior of the widget should appear relative |
| to its exterior; for example, \fBraised\fR means the interior of |
| the widget should appear to protrude from the screen, relative to |
| the exterior of the widget. |
| .OP \-repeatdelay repeatDelay RepeatDelay |
| Specifies the number of milliseconds a button or key must be held |
| down before it begins to auto-repeat. Used, for example, on the |
| up- and down-arrows in scrollbars. |
| .OP \-repeatinterval repeatInterval RepeatInterval |
| Used in conjunction with \fBrepeatDelay\fR: once auto-repeat |
| begins, this option determines the number of milliseconds between |
| auto-repeats. |
| .OP \-selectbackground selectBackground Foreground |
| Specifies the background color to use when displaying selected |
| items. |
| .OP \-selectborderwidth selectBorderWidth BorderWidth |
| Specifies a non-negative value indicating the width |
| of the 3-D border to draw around selected items. |
| The value may have any of the forms acceptable to \fBTk_GetPixels\fR. |
| .OP \-selectforeground selectForeground Background |
| Specifies the foreground color to use when displaying selected |
| items. |
| .OP \-setgrid setGrid SetGrid |
| Specifies a boolean value that determines whether this widget controls the |
| resizing grid for its top-level window. |
| This option is typically used in text widgets, where the information |
| in the widget has a natural size (the size of a character) and it makes |
| sense for the window's dimensions to be integral numbers of these units. |
| These natural window sizes form a grid. |
| If the \fBsetGrid\fR option is set to true then the widget will |
| communicate with the window manager so that when the user interactively |
| resizes the top-level window that contains the widget, the dimensions of |
| the window will be displayed to the user in grid units and the window |
| size will be constrained to integral numbers of grid units. |
| See the section GRIDDED GEOMETRY MANAGEMENT in the \fBwm\fR manual |
| entry for more details. |
| .OP \-takefocus takeFocus TakeFocus |
| Determines whether the window accepts the focus during keyboard |
| traversal (e.g., Tab and Shift-Tab). |
| Before setting the focus to a window, the traversal scripts |
| consult the value of the \fBtakeFocus\fR option. |
| A value of \fB0\fR means that the window should be skipped entirely |
| during keyboard traversal. |
| \fB1\fR means that the window should receive the input |
| focus as long as it is viewable (it and all of its ancestors are mapped). |
| An empty value for the option means that the traversal scripts make |
| the decision about whether or not to focus on the window: the current |
| algorithm is to skip the window if it is |
| disabled, if it has no key bindings, or if it is not viewable. |
| If the value has any other form, then the traversal scripts take |
| the value, append the name of the window to it (with a separator space), |
| and evaluate the resulting string as a Tcl script. |
| The script must return \fB0\fR, \fB1\fR, or an empty string: a |
| \fB0\fR or \fB1\fR value specifies whether the window will receive |
| the input focus, and an empty string results in the default decision |
| described above. |
| Note: this interpretation of the option is defined entirely by |
| the Tcl scripts that implement traversal: the widget implementations |
| ignore the option entirely, so you can change its meaning if you |
| redefine the keyboard traversal scripts. |
| .OP \-text text Text |
| Specifies a string to be displayed inside the widget. The way in which |
| the string is displayed depends on the particular widget and may be |
| determined by other options, such as \fBanchor\fR or \fBjustify\fR. |
| .OP \-textvariable textVariable Variable |
| Specifies the name of a variable. The value of the variable is a text |
| string to be displayed inside the widget; if the variable value changes |
| then the widget will automatically update itself to reflect the new value. |
| The way in which the string is displayed in the widget depends on the |
| particular widget and may be determined by other options, such as |
| \fBanchor\fR or \fBjustify\fR. |
| .OP \-troughcolor troughColor Background |
| Specifies the color to use for the rectangular trough areas |
| in widgets such as scrollbars and scales. This option is ignored for |
| scrollbars on Windows (native widget doesn't recognize this option). |
| .OP \-underline underline Underline |
| Specifies the integer index of a character to underline in the widget. |
| This option is used by the default bindings to implement keyboard |
| traversal for menu buttons and menu entries. |
| 0 corresponds to the first character of the text displayed in the |
| widget, 1 to the next character, and so on. |
| .OP \-wraplength wrapLength WrapLength |
| For widgets that can perform word-wrapping, this option specifies |
| the maximum line length. |
| Lines that would exceed this length are wrapped onto the next line, |
| so that no line is longer than the specified length. |
| The value may be specified in any of the standard forms for |
| screen distances. |
| If this value is less than or equal to 0 then no wrapping is done: lines |
| will break only at newline characters in the text. |
| .OP \-xscrollcommand xScrollCommand ScrollCommand |
| Specifies the prefix for a command used to communicate with horizontal |
| scrollbars. |
| When the view in the widget's window changes (or |
| whenever anything else occurs that could change the display in a |
| scrollbar, such as a change in the total size of the widget's |
| contents), the widget will |
| generate a Tcl command by concatenating the scroll command and |
| two numbers. |
| Each of the numbers is a fraction between 0 and 1, which indicates |
| a position in the document. 0 indicates the beginning of the document, |
| 1 indicates the end, .333 indicates a position one third the way through |
| the document, and so on. |
| The first fraction indicates the first information in the document |
| that is visible in the window, and the second fraction indicates |
| the information just after the last portion that is visible. |
| The command is |
| then passed to the Tcl interpreter for execution. Typically the |
| \fBxScrollCommand\fR option consists of the path name of a scrollbar |
| widget followed by ``set'', e.g. ``.x.scrollbar set'': this will cause |
| the scrollbar to be updated whenever the view in the window changes. |
| If this option is not specified, then no command will be executed. |
| .OP \-yscrollcommand yScrollCommand ScrollCommand |
| Specifies the prefix for a command used to communicate with vertical |
| scrollbars. This option is treated in the same way as the |
| \fBxScrollCommand\fR option, except that it is used for vertical |
| scrollbars and is provided by widgets that support vertical scrolling. |
| See the description of \fBxScrollCommand\fR for details |
| on how this option is used. |
