NAME
Tk::NumEntryPlain - A numeric entry widget
SUPPORTED PLATFORMS
- Linux
- Solaris
- Windows
SYNOPSIS
use Tk::NumEntryPlain;
DESCRIPTION
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
STANDARD OPTIONS
-repeatdelay -repeatinterval
WIDGET-SPECIFIC OPTIONS
- -minvalue
-
Defines the minimum legal value that the widget can hold. If this
value is
undefthen there is no minimum value (default = undef). - -maxvalue
-
Defines the maximum legal value that the widget can hold. If this
value is
undefthen 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.
CAVEATS
- -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.
