.SH "NAME"
Tk::NumEntryPlain \- A numeric entry widget
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
\&\fBuse Tk::NumEntryPlain;\fR
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fBTk::NumEntryPlain\fR defines a widget for entering integer numbers.
.PP
\&\fBTk::NumEntryPlain\fR supports all the options and methods that a normal
Entry widget provides, plus the following options
.SH "STANDARD OPTIONS"
.IX Header "STANDARD OPTIONS"
\&\fB\-repeatdelay\fR
\&\fB\-repeatinterval\fR
.SH "WIDGET-SPECIFIC OPTIONS"
.IX Header "WIDGET-SPECIFIC OPTIONS"
.IP "\-minvalue" 4
.IX Item "-minvalue"
Defines the minimum legal value that the widget can hold. If this
value is \f(CW\*(C`undef\*(C'\fR then there is no minimum value (default = undef).
.IP "\-maxvalue" 4
.IX Item "-maxvalue"
Defines the maximum legal value that the widget can hold. If this
value is \f(CW\*(C`undef\*(C'\fR then there is no maximum value (default = undef).
.IP "\-bell" 4
.IX Item "-bell"
Specifies a boolean value. If true then a bell will ring if the user
attempts to enter an illegal character into the entry widget, and
when the user reaches the upper or lower limits when using the
up/down buttons for keys (default = true).
.IP "\-textvariable" 4
.IX Item "-textvariable"
Reference to a scalar variable that contains the value currently
in the \fBNumEntry\fR.  Use the variable only for reading (see
\&\*(L"\s-1CAVEATS\*(R"\s0 below).
.IP "\-value" 4
.IX Item "-value"
Specifies the value to be inserted into the entry widget. Similar
to the standard \fB\-text\fR option, but will perform a range
check on the value.
.IP "\-command" 4
.IX Item "-command"
A callback which is called if <Return> is pressed.
.IP "\-browsecmd" 4
.IX Item "-browsecmd"
A callback which is called every time an increment or decrement
happens in the entry widget.
.SH "WIDGET METHODS"
.IX Header "WIDGET METHODS"
.IP "\fI\f(CI$numentry\fI\fR\->\fBincdec\fR(\fIincrement\fR)" 4
.IX Item "$numentry->incdec(increment)"
Increment the value of the entry widget by the specified increment. If
increment is 0, then perform a range check.
.SH "CAVEATS"
.IX Header "CAVEATS"
.IP "\-textvariable" 4
.IX Item "-textvariable"
\&\fB\-textvariable\fR should only be used to read out the current
value in the \fBNumEntry\fR.
.Sp
Values set via \fB\-textvariable\fR are not valided. Therefore
it's possible to insert, e.g., 'abc', into the \fBNumEntry\fR.
.SH "SEE ALSO"
.IX Header "SEE ALSO"
Tk::NumEntry
Tk::Entry
.SH "HISTORY"
.IX Header "HISTORY"
