Tk::NumEntryPlain - A numeric entry widget
use Tk::NumEntryPlain;
Tk::NumEntryPlain defines a widget for entering integer numbers.
Tk::NumEntryPlain supports all the options and methods that a normal
Entry widget provides, plus the following options
-repeatdelay
-repeatinterval
- -minvalue
-
Defines the minimum legal value that the widget can hold. If this
value is
undef
then there is no minimum value (default = undef).
- -maxvalue
-
Defines the maximum legal value that the widget can hold. If this
value is
undef
then there is no maximum value (default = undef).
- -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).
- -textvariable
-
Reference to a scalar variable that contains the value currently
in the NumEntry. Use the variable only for reading (see
CAVEATS below).
- -value
-
Specifies the value to be inserted into the entry widget. Similar
to the standard -text option, but will perform a range
check on the value.
- -command
-
A callback which is called if <Return> is pressed.
- -browsecmd
-
A callback which is called every time an increment or decrement
happens in the entry widget.
- $numentry->incdec(increment)
-
Increment the value of the entry widget by the specified increment. If
increment is 0, then perform a range check.
- -textvariable
-
-textvariable should only be used to read out the current
value in the NumEntry.
-
Values set via -textvariable are not valided. Therefore
it's possible to insert, e.g., 'abc', into the NumEntry.
