### NAME

tixControl - Create and manipulate tixControl widgets

### SYNOPSIS

tixControl pathName ?options?

### SUPER-CLASS

The TixControl class is derived from the TixLabelWidget class and inherits all the commands, options and subwidgets of its super-class.

### STANDARD OPTIONS

The Control widget supports all the standard options of a frame widget. See the options manual entry for details on the standard options.

### WIDGET-SPECIFIC OPTIONS

Command-Line Name: -allowempty
Database Name: allowEmpty
Database Class: AllowEmpty
  Specifies whether the Control widget should allow the empty string as a valid input.

Command-Line Name: -autorepeat
Database Name: autorepeat
Database Class: AutoRepeat
  Specifies whether the Control widget should have autorepeat behavior. If set to be "true", the value of the Control widget will be automatically incremented or decremented when the user holds down the mouse button over the arrow buttons. Only values "true" and "false" will be recognized.

Command-Line Name: -command
Database Name: command
Database Class: Command
  Specifies the command to be called when the -value option of the Control widget is changed. The command will be called with one arguments -- the new value of the Control widget.

Command-Line Name: -decrcmd
Database Name: decrCmd
Database Class: DecrCmd
  Specifies a TCL command to be called when the the user presses the down-arrow button subwidget. This command is called with one parameter -- the current -value of this Control widget. This command is to decrement this value by one step, according to its own definition of "decrement", and return the decremented value, which will be stored in the -value of this Control widget.

Command-Line Name: -disablecallback
Database Name: disableCallback
Database Class: DisableCallback
  A boolean value indicating whether callbacks should be disabled. When set to true, the TCL command specified by the -command option is not executed when the -value of the Control widget changes.

Command-Line Name: -disableforeground
Database Name: disableForeground
Database Class: DisableForeground
  The foreground color to use for of the entry subwidget when the Control widget is disabled.

Command-Line Name: -incrcmd
Database Name: incrCmd
Database Class: IncrCmd
  Specifies a TCL command to be called when the the user presses the up-arrow button subwidget. This command is called with one parameter -- the current -value of this Control widget. This command is to increment this value by one step, according to its own definition of "increment", and return the incremented value, which will be stored in the -value of this Control widget.

Command-Line Name: -initwait
Database Name: initwait
Database Class: Initwait
  Specifies how long the Control widget should wait initially before it starts to automatically increment or decrement its value in the autorepeat mode. In milliseconds.

Command-Line Name: -integer
Database Name: integer
Database Class: Integer
  A Boolean value specifying whether only integer numbers are accepted.

Command-Line Name: -label
Database Name: label
Database Class: Label
  Specifies the string to display as the label of this Control widget.

Command-Line Name: -labelside
Database Name: labelSide
Database Class: LabelSide
  Specifies where the label should be displayed relative to the entry subwidget. Valid options are: top, left, right, bottom, none or acrosstop.

Name: max
Class: Max
Switch: -max
Alias: -ulimit

  Specifies the upper limit of the value of the Control widget. When set to empty string, the Control widget has no upper limit.

Name: min
Class: Min
Switch: -min
Alias: -llimit

  Specifies the lower limit of the value of the Control widget.When set to empty string, the Control widget has no lower limit.

Command-Line Name: -repeatrate
Database Name: repeatRate
Database Class: RepeatRate
  Specifies how often the value of the Control widget should be incremented or decremented when it is in the autorepeat mode. In milliseconds.

Command-Line Name: -selectmode
Database Name: selectMode
Database Class: SelectMode
  Specifies how the Control widget should react to `<KeyPress>` events. When set to "immediate", any user keyboard inputs will immediately change the -value option. When set to "normal", the user keyboard inputs will be copied to the -value option only if the`<Return>` key is pressed or the keyboard focus is changed. The use of the immediate mode is discouraged. For effective use of the Control widget, one should use the normal mode together with the update widget command (see below).

Command-Line Name: -state
Database Name: state
Database Class: State
  Specifies the whether the Control widget is normal or disabled. Only the values "normal" and "disabled" are recognized.

Command-Line Name: -step
Database Name: step
Database Class: Step
  Specifies by how much the value of the Control widget should be incremented or decrmented when the user press the arrow buttons.

Command-Line Name: -validatecmd
Database Name: validateCmd
Database Class: ValidateCmd
  Specifies a TCL command to be called when the -value of the Control widget is about to change. This command is called with one parameter -- the new -value entered by the user. This command is to validate this new value by returning a value it deems valid.

Command-Line Name: -value
Database Name: value
Database Class: Value
  Specifies the value of the Control widget.

Command-Line Name: -variable
Database Name: variable
Database Class: Variable
  Specifies the global variable in which the value of the Control widget should be stored. The value of the Control widget will be automatically updated when this variable is changed.

### SUBWIDGETS

Name: decr
Class: Button

  The down arrow button.

Name: entry
Class: Entry

  The entry that shows the value of this Control widget.

Name: incr
Class: Button

  The up arrow button.

Name: label
Class: Label

  The label subwidget.

### DESCRIPTION

The tixControl command creates a new window (given by the pathName argument) and makes it into a Control widget. Additional options, described above, may be specified on the command line or in the option database to configure aspects of the Control widget such as its cursor and relief. The Control widget is also known as the SpinBox widget. It is generally used to control a value. The user can adjust the value by pressing the two arrow buttons or by entering the value directly into the entry. The new value will be checked against the user-defined upper and lower limits.

### WIDGET COMMANDS

The tixControl command creates a new Tcl command whose name is the same as the path name of the Control widget's window. This command may be used to invoke various operations on the widget. It has the following general form:

      pathName option ?arg arg ...?

PathName is the name of the command, which is the same as the Control widget's path name. Option and the args determine the exact behavior of the command. The following commands are possible for Control widgets:

pathName cget option
  Returns the current value of the configuration option given by option. Option may have any of the values accepted by the tixControl command.

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 tixControl command.

pathName decr
  Decrements the value of the Control widget by the step specified by the -step option.

pathName incr
  Increments the value of the Control widget by the step specified by the -step option.

pathName invoke
  Causes the command specified by the -command option to be invoked.

pathName update
  If the user has modified the entry using keyboard inputs, the update command will update the -value of this Control widget. When the Control widget's -selectmode option is set to "normal", one should call the update command on this widget before examining its -value option. This command has no effect in if the -selectmode option is set to "immediate".

pathName subwidget name ?args?
  When no options are given, this command returns the pathname of the subwidget of the specified name. When options are given, the widget command of the specified subwidget will be called with these options.

### BINDINGS

When the user presses the up/down arrow buttons (or press the <Up> and <Down> arrow keys on the keyboard), the value of the tixControl widget is adjusted according to the -validatecmd, -incrcmd, -decrcmd, -step, -max and -min options.
