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]
