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 gener-
ally 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 wid-
gets:
pathName cget option
Returns the current value of the configuration option given by
option. Option may have any of the values accepted by the tix-
Control 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 avail-
able 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 examin-
ing 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 sub-
widget 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.
