tixSelect - Create and manipulate tixSelect widgets

tixSelect pathName ?options?

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

The Select widget supports all the standard options of a frame widget. See the options(n) manual entry for details on the standard options.

[-allowzero allowZero] A boolean value that specifies whether the selection can be empty. When set to false, at least one button subwidget must be selected at any time.
Note: When the Select widget is first constructed, the default selection is always empty, even if -allowzero is set to false. [-buttontype buttonType] The type of buttons to be used as subwidgets inside the Select widget. By default, the standard Tk button widget class is used. [-command command] Specifies the TCL command to be executed when the -value of the Select widget is changed. This command will be invoked with two arguments. The first is the name of the button subwidget that has toggled. The second is a boolean value indicating whether the button subwidget is selected. This command is executed only when the -disableCallback option is set to false. [-disablecallback 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 Select widget changes.
Name:		 orientation
Class:		 Orientation
Switch:		 -orientation
Alias:		 -orient
Specifies the orientation of the button subwidgets. Only the values horizontal and vertical are recognized. This is a static option and it can only be assigned during the creation of the widget. [-label label] Specifies the string to display as the label of this Select widget. [-labelside labelSide] Specifies where the label should be displayed relative to the Select widget. Valid options are: top, left, right, bottom, none or acrosstop. [-padx padX] Specifies the horizontal padding between two neighboring button subwidgets. This is a static option and it can only be assigned during the creation of the widget. [-padx padY] Specifies the vertical padding between two neighboring button subwidgets. This is a static option and it can only be assigned during the creation of the widget. [-radio radio] A boolean value that specifies whether the Select widget should act as a radio-box. When set to true, at most one button subwidget can be selected at any time. This is a static option and it can only be assigned during the creation of the widget. [-selectedbg selectedBg] Specifies the background color of all the selected button subwidgets. [-state state] Specifies the state of all the buttons inside the Select widget. Only the values normal and disabled are recognized. When the state is set to disabled, all user actions on this Select widget are ignore. [-validatecmd validateCmd] Specifies a TCL command to be called when the -value of the Select 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. [-value value] The value of a Select widget is a list of the names of the button subwidgets that have been selected by the user.
When you assign the value of a Select widget using the "config -value" widget command, the TCL command specified by the -command option will be invoked if some button subwidgets are toggled. [-variable variable] Specifies the global variable in which the value of the Select widget should be stored. The value of a Select widget is stored as a list of the names of the button subwidgets that have been selected by the user. The value of the Select widget will be automatically updated when this variable is changed.

Name:		 label
Class:		 Label
The label subwidget.
In addition, all the button subwidgets created as a result of the add widget command can be accessed by the subwidget command. They are identified by the buttonName parameter to the add widget command. Here is an example:
set s [tixSelect .s] pack $s $s add eat -text Eat $s add sleep -text Sleep $s subwidget eat config -fg green $s subwidget sleep config -fg red

The tixSelect command creates a new window (given by the pathName argument) and makes it into a Select widget. Additional options, described above, may be specified on the command line or in the option database to configure aspects of the Select widget such as its cursor and relief.
The Select widget is a container of button subwidgets. It can be used to provide radio-box or check-box style of selection options for the user.

The tixSelect command creates a new Tcl command whose name is the same as the path name of the Select 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 Select widget's path name. Option and the args determine the exact behavior of the command. The following commands are possible for Select widgets:
pathName add buttonName ?option value ... ?
Adds a new button subwidget with the name buttonName into the Select widget. Additional configuration options can be given to configure the new button subwidget.
pathName cget option
Returns the current value of the configuration option given by option. Option may have any of the values accepted by the tixSelect 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 tixSelect command.
pathName invoke buttonName
Invokes the button subwidget with the name buttonName.
pathName subwidget name ?args?
When no options are given, 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.

When the user presses the left mouse button over the a button subwidget, it will be toggled and the -value option of the tixSelect widget will be changed.

The following example creates a radio-box style iconbar for the user to choose one value among eat, work or sleep.
set s [tixSelect .s -radio true -allowzero false] $s add eat -bitmap [tix getbitmap eat] $s add work -bitmap [tix getbitmap work] $s add sleep -bitmap [tix getbitmap sleep]
