RhsPack

DecimalNumberEdit is a component for entering numbers. The input field only accepts valid numbers that can be limited using the Matrix property. The component provides four new properties. 1. Matrix (string) The number format is defined via this property. Examples: 99.99 Allows you to enter values in the range from 0 to 99.99 with two decimal places. -50.9 Allows you to enter values in the range from -50.9 to 50.9 with one decimal place. 250.000 Allows you to enter values in the range from 0 to 250 with three decimal places. -500 Allows you to enter values in the range from -500 to 500 without decimal places. 2. Value (Extended) Returns the extended value of the entered value. This value can be evaluated during input and represents the value currently entered in the input field. 3. EnterKey (Boolean) Allows the Enter key to be used in the same way as the Tab key. 4. WarningTone (Boolean) Outputs a warning tone when illegal entries are made.
