command
Specifies a Python callback to invoke whenever a spinbutton is invoked. The callback recognizes several percent substitutions: "%W" for the widget path, "%s" for the current value of the widget, and "%d" for the direction of the button pressed (up or down).
disabledbackground
Specifies the background color to use when the spinbox is disabled. If this option is the empty string, the normal background color is used.
disabledforeground
Specifies the foreground color to use when the spinbox is disabled. If this option is the empty string, the normal foreground color is used.
format
Specifies an alternate format to use when setting the string value when using the -from and -to range. This must be a format specifier of the form "%<pad>.<pad>f", as it will format a floating-point number.
from_
A floating-point value corresponding to the lowest value for a spinbox, to be used in conjunction with to and increment. When all are specified correctly, the spinbox will use these values to control its contents. If this value is greater than the to option, then from and to values are automatically swapped. If values is specified, it supersedes this option.
invalidcommand or invcmd
Specifies a script to eval when validatecommand returns 0. Setting it to an empty string disables this feature (the default). The best use of this option is to set it to bell(). See VALIDATION below for more information.
increment
A floating-point value specifying the increment. When used with from and to, the value in the widget will be adjusted by increment when a spin button is pressed (up adds the value, down subtracts the value).
readonlybackground
Specifies the background color to use when the spinbox is readonly. If this option is the empty string, the normal background color is used.
state
Specifies one of three states for the spinbox: "normal", "disabled", or "readonly". If the spinbox is "readonly", then the value may not be changed using widget commands and no insertion cursor will be displayed, even if the input focus is in the widget; the contents of the widget may still be selected. If the spinbox is "disabled", the value may not be changed, no insertion cursor will be displayed, the contents will not be selectable, and the spinbox may be displayed in a different color, depending on the values of the disabledforeground and disabledbackground options.
to
A floating-point value corresponding to the highest value for the spinbox, to be used in conjunction with from and increment. When all are specified correctly, the spinbox will use these values to control its contents. If this value is less than the from option, then from and to values are automatically swapped. If values is specified, it supersedes this option.
validate
Specifies the mode in which validation should operate: "none", "focus", "focusin", "focusout", "key", or "all". It defaults to "none". When you want validation, you must explicitly state which mode you wish to use. See VALIDATION below for more.
validatecommand or vcmd
Specifies a script to evaluate when you want to validate the input in the widget. Setting it to an empty string disables this feature (the default). Validation occurs according to the value of validate. This command must return a valid Python boolean value. If it returns 0 (or the valid Python boolean equivalent) then the value of the widget will not change and the invalidcommand will be evaluated if it is set. If it returns 1, then value will be changed. See VALIDATION below for more information.
values
Must be a proper list value. If specified, the spinbox will use these values as to control its contents, starting with the first value. This option has precedence over the from and to range.
width
Specifies an integer value indicating the desired width of the spinbox window, in average-size characters of the widget's font. If the value is less than or equal to zero, the widget picks a size just large enough to hold its current text
wrap
Must be a proper boolean value. If on, the spinbox will wrap around the values of data in the widget.
A Spinbox is an extended Entry widget that allows he user to move, or spin, through a fixed set of ascending or descending values such as times or dates in addition to editing the value as in an Entry. When first created, a Spinbox's string is empty. A portion of the Spinbox may be selected as described below. If a Spinbox is exporting its selection (see the exportselection option), then it will observe the standard protocols for handling the selection; Spinbox selections are available as type string. Spinboxes also observe the standard Tkinter rules for dealing with the input focus. When a Spinbox has the input focus it displays an insertion cursor to indicate where new characters will be inserted. Spinboxes are capable of displaying strings that are too long to fit entirely within the widget's window. In this case, only a portion of the string will be displayed; commands described below may be used to change the view in the window. Spinboxes use the standard xscrollcommand mechanism for interacting with scrollbars (see the description of the xscrollcommand option for details). They also support scanning, as described below.
Validation works by setting the validatecommand option to a script which will be evaluated according to the validate option as follows:
"none"
Default. This means no validation will occur.
"focus"
The validatecommand will be called when the spinbox receives or loses focus.
"focusin"
The validatecommand will be called when the spinbox receives focus.
"focusout"
The validatecommand will be called when the spinbox loses focus.
"key"
The validatecommand will be called when the spinbox is edited.
"all"
The validatecommand will be called for all above conditions.
The following substitutions are recognized:
"%d"
Type of action: 1 for insert, 0 for delete, or -1 for focus, forced or textvariable validation.
"%i"
Index of char string to be inserted/deleted, if any, otherwise -1.
"%P"
The value of the spinbox should edition occur. If you are configuring the spinbox widget to have a new textvariable, this will be the value of that textvariable.
"%s"
The current value of spinbox before edition.
"%S"
The text string being inserted/deleted, if any. Otherwise it is an empty string.
"%v"
The type of validation currently set.
"%V"
The type of validation that triggered the callback (key, focusin, focusout, forced).
"%W"
The name of the spinbox widget.
In general, the textvariable and validatecommand can be dangerous to mix. Any problems have been overcome so that using the validatecommand will not interfere with the traditional behavior of the spinbox widget. Using the textvariable for read-only purposes will never cause problems. The danger comes when you try set the textvariable to something that the validatecommand would not accept, which causes validate to become "none" (the invalidcommand will not be triggered). The same happens when an error occurs evaluating the validatecommand.
Many of the widget commands for spinboxes take one or more indices as arguments. An index specifies a particular character in the spinbox's string, in any of the following ways:
number
Specifies the character as a numerical index, where 0 corresponds to the first character in the string.
"anchor"
Indicates the anchor point for the selection, which is set with the select_from() and select_adjust() widget methods.
"end"
Indicates the character just after the last one in the spinbox's string. This is equivalent to specifying a numerical index equal to the length of the spinbox's string.
"insert"
Indicates the character adjacent to and immediately following the insertion cursor.
"sel.first"
Indicates the first character in the selection. It is an error to use this form if the selection is not in the spinbox window.
"sel.last"
Indicates the character just after the last one in the selection. It is an error to use this form if the selection is not in the spinbox window.
@number
In this form, number is treated as an x-coordinate in the spinbox's window; the character spanning that x-coordinate is used. For example, "@0" indicates the left-most character in the window.
The following commands are possible for spinbox widgets:
instance.bbox(index)
Returns a list of four numbers describing the bounding box of the character given by index. The first two elements of the list give the x and y coordinates of the upper-left corner of the screen area covered by the character (in pixels relative to the widget) and the last two elements give the width and height of the character, in pixels. The bounding box may refer to a region outside the visible area of the window.
instance.cget("option")
Returns the current value of the configuration option given by option. Option may have any of the values accepted by the Spinbox class.
instance.configure()
instance.configure("option")
instance.configure(**options)
Query or modify the configuration options of the widget.
If no option is specified, returns a list describing all of the available options for instance: the elements of the list are the option name, database name, database class, default value, and current value.
If "option" is specified, then the method 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 **options are specified, then the command modifies the given widget option(s) to have the given value(s); in this case the method returns an empty string. Option may have any of the values accepted by the Spinbox class.
instance.delete(first ,last)
Delete one or more elements of the spinbox. First is the index of the first character to delete, and last is the index of the character just after the last one to delete. If last is not specified it defaults to first+1, i.e. a single character is deleted. This command returns an empty string.
instance.get()
Returns the spinbox's string.
instance.icursor(index)
Arrange for the insertion cursor to be displayed just before the character given by index. Returns an empty string.
instance.identify(x ,y)
Returns the name of the window element corresponding to coordinates x and y in the spinbox. Return value is one of: empty string, buttondown, buttonup, entry.
instance.index(index)
Returns the numerical index corresponding to index.
instance.insert(index ,"string")
Insert the characters of "string" just before the character indicated by index. Returns an empty string.
instance.invoke("element")
Causes the specified element, either "buttondown" or "buttonup", to be invoked, triggering the action associated with it.
instance.scan_mark(x)
Records x and the current view in the spinbox window; used in conjunction with later scan_dragto() methods. Typically this command is associated with a mouse button press in the widget. It returns an empty string.
instance.scan_dragto(x)
This command computes the difference between its x argument and the x argument to the last scan_mark() method for the widget. It then adjusts the view left or right by 10 times the difference in x-coordinates. This command is typically associated with mouse motion events in the widget, to produce the effect of dragging the spinbox at high speed through the window. The return value is an empty string.
instance.selection_adjust(index)
Locate the end of the selection nearest to the character given by index, and adjust that end of the selection to be at index (i.e. including but not going beyond index). The other end of the selection is made the anchor point for future select_to() methods. If the selection is not currently in the spinbox, then a new selection is created to include the characters between index and the most recent selection anchor point, inclusive. Returns an empty string.
instance.selection_clear()
Clear the selection if it is currently in this widget. If the selection is not in this widget then the command has no effect. Returns an empty string.
instance.selection("from' ,index)
Set the selection anchor point to just before the character given by index. Does not change the selection. Returns an empty string.
instanceselection("range" ,start ,end)
Sets the selection to include the characters starting with the one indexed by start and ending with the one just before end. If end refers to the same character as start or an earlier one, then the spinbox's selection is cleared.
instance.selection_to(index)
If index is before the anchor point, set the selection to the characters from index up to but not including the anchor point. If index is the same as the anchor point, do nothing. If index is after the anchor point, set the selection to the characters from the anchor point up to but not including index. The anchor point is determined by the most recent select_from() or select_adjust() method in this widget. If the selection is not in this widget then a new selection is created using the most recent anchor point specified for the widget. Returns an empty string.
instance.xview()
Returns a list containing two elements. Each element is a real fraction between 0 and 1; together they describe the horizontal span that is visible in the window. For example, if the first element is .2 and the second element is .6, 20% of the spinbox's text is off-screen to the left, the middle 40% is visible in the window, and 40% of the text is off-screen to the right. These are the same values passed to scrollbars via the xscrollcommand option.
instance.xview(index)
Adjusts the view in the window so that the character given by index is displayed at the left edge of the window.
instance.xview_moveto(fraction)
Adjusts the view in the window so that the character fraction of the way through the text appears at the left edge of the window. Fraction must be a fraction between 0 and 1.
instance.xview_scroll(number ,"what")
This command shifts the view in the window left or right according to number and what. Number must be an integer. What must be either "units" or "pages" or an abbreviation of one of these. If what is "units", the view adjusts left or right by number average-width characters on the display; if it is "pages"' then the view adjusts by number screenfuls. If number'' is negative then characters farther to the left become visible; if it is positive then characters farther to the right become visible.
In the descriptions below, “word” refers to a contiguous group of letters, digits, or “_” characters, or any single character other than these.
1. Clicking mouse button 1 positions the insertion cursor just before the character underneath the mouse cursor, sets the input focus to this widget, and clears any selection in the widget. Dragging with mouse button 1 strokes out a selection between the insertion cursor and the character under the mouse.
2. Double-clicking with mouse button 1 selects the word under the mouse and positions the insertion cursor at the beginning of the word. Dragging after a double click will stroke out a selection consisting of whole words.
3. Triple-clicking with mouse button 1 selects all of the text in the spinbox and positions the insertion cursor before the first character.
4. The ends of the selection can be adjusted by dragging with mouse button 1 while the Shift key is down; this will adjust the end of the selection that was nearest to the mouse cursor when button 1 was pressed. If the button is double-clicked before dragging then the selection will be adjusted in units of whole words.
5. Clicking mouse button 1 with the Control key down will position the insertion cursor in the spinbox without affecting the selection.
6. If any normal printing characters are typed in a spinbox, they are inserted at the point of the insertion cursor.
7. The view in the spinbox can be adjusted by dragging with mouse button 2. If mouse button 2 is clicked without moving the mouse, the selection is copied into the spinbox at the position of the mouse cursor.
8. If the mouse is dragged out of the spinbox on the left or right sides while button 1 is pressed, the spinbox will automatically scroll to make more text visible (if there is more text off-screen on the side where the mouse left the window).
9. The Left and Right keys move the insertion cursor one character to the left or right; they also clear any selection in the spinbox and set the selection anchor. If Left or Right is typed with the Shift key down, then the insertion cursor moves and the selection is extended to include the new character. Control-Left and Control-Right move the insertion cursor by words, and Control-Shift-Left and Control-Shift-Right move the insertion cursor by words and also extend the selection. Control-b and Control-f behave the same as Left and Right, respectively. Meta-b and Meta-f behave the same as Control-Left and Control-Right, respectively.
10. The Home key, or Control-a, will move the insertion cursor to the beginning of the spinbox and clear any selection in the spinbox. Shift-Home moves the insertion cursor to the beginning of the spinbox and also extends the selection to that point.
11. The End key, or Control-e, will move the insertion cursor to the end of the spinbox and clear any selection in the spinbox. Shift-End moves the cursor to the end and extends the selection to that point.
12. The Select key and Control-Space set the selection anchor to the position of the insertion cursor. They do not affect the current selection. Shift-Select and Control-Shift-Space adjust the selection to the current position of the insertion cursor, selecting from the anchor to the insertion cursor if there was not any selection previously.
13. Control-/ selects all the text in the spinbox.
14. Control-\ clears any selection in the spinbox.
15. The F16 key (labelled Copy on many Sun workstations) or Meta-w copies the selection in the widget to the clipboard, if there is a selection.
16. The F20 key (labelled Cut on many Sun workstations) or Control-w copies the selection in the widget to the clipboard and deletes the selection. If there is no selection in the widget then these keys have no effect.
17. The F18 key (labelled Paste on many Sun workstations) or Control-y inserts the contents of the clipboard at the position of the insertion cursor.
18. The Delete key deletes the selection, if there is one in the spinbox. If there is no selection, it deletes the character to the right of the insertion cursor.
19. The BackSpace key and Control-h delete the selection, if there is one in the spinbox. If there is no selection, it deletes the character to the left of the insertion cursor.
20. Control-d deletes the character to the right of the insertion cursor.
21. Meta-d deletes the word to the right of the insertion cursor.
22. Control-k deletes all the characters to the right of the insertion cursor.
23. Control-t reverses the order of the two characters to the right of the insertion cursor.
If the spinbox is disabled using the state option, then the spinbox's view can still be adjusted and text in the spinbox can still be selected, but no insertion cursor will be displayed and no text modifications will take place.
The behavior of spinboxes can be changed by defining new bindings for individual widgets or by redefining the class bindings.
