Tk::NumEntryPlain - A numeric entry widget
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.
