DESCRIPTIONTk::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
STANDARD OPTIONS-repeatdelay -repeatinterval
- Defines the minimum legal value that the widget can hold. If this value is "undef" then there is no minimum value (default = undef).
- Defines the maximum legal value that the widget can hold. If this value is "undef" then there is no maximum value (default = undef).
- 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).
- Reference to a scalar variable that contains the value currently in the NumEntry. Use the variable only for reading (see ``CAVEATS'' below).
- 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.
- A callback which is called if <Return> is pressed.
- A callback which is called every time an increment or decrement happens in the entry widget.
- Increment the value of the entry widget by the specified increment. If increment is 0, then perform a range check.
-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.
