getTextAsReal

getTextAsReal(): Real;

The getTextAsReal method returns the text from the textUser property of a JadeEditMask control or the text property of a TextBox control converted to a Real value.

If the text of a JadeEditMask control is not a valid numeric string in the locale of the control (for details, see the languageId property), an exception is raised. You should therefore use this method only when the mask property of the control indicates a numeric field (for example, ###,##9.#) that guarantees that the text is a valid numeric. The text can be valid but incomplete, according to the mask (for details, see the isEmpty and isValid methods).

If the text of a TextBox control is not a valid numeric string in the locale of the user application or it is empty, an exception is raised. You should therefore use this method only for a numeric text box (that is, the dataType property value of DataType_Numeric (1), DataType_SignedNumeric (2), or DataType_Currency (3)) that guarantees that the text is a valid numeric.

When the EnhancedLocaleSupport parameter in the [JadeEnvironment] section of the JADE initialization file on the database node is set to true, the JadeEditMask class validates the setting and entry of text based on the mask property, using the current locale of the client with regional overrides on both the presentation client and the application server.

When the EnhancedLocaleSupport parameter is not defined or it is set to false, inconsistent results could be returned to the application server when running in JADE thin client mode and there are regional overrides, as all overrides on the application server are suppressed. By default, formatting of locale data is done on the application server, based on the locale of the corresponding presentation client.

A numeric JadeEditMask control expects the negative sign, decimal place, and separator characters to be in the form defined for the locale that the control is using. A numeric TextBox control expects the negative sign and decimal place characters to be in the form defined for the locale under which the user is running. This applies when accessing the text or textUser properties and when the user enters data.

Setting text by using the setTextFromReal method converts the integer into the appropriate string for that locale. Retrieving the Real value using the getTextAsReal does the reverse. You can therefore use the getTextAsReal and setTextFromReal methods to access numeric text so that JADE handles the locale format for you.

The position of a negative sign indicated by the locale is honored by a leading or trailing numeric in the JadeEditMask or TextBox control. However, locales that specify a negative value expressed by parentheses (for example, (123)) are treated as a leading dash symbol (-). In addition, locales that have a leading or trailing space associated with a negative sign are treated as the equivalent format without the space (for example, - 123 will be ‑123 and 123 - will be 123‑).
