Validation-Regexp

This property allows you to specify a regular expression for the validation of the Entry-Field content. When the user leave the field, if the content doesn’t match with the regular expression, then a message box is shown and the focus is kept on the field. The message box text is controlled by the property Validation-Errmsg. The validation is performed according to the settings specified by Validation-Opts.

 

Example - Define an entry-field that accepts digits only, validating with regular expression and defining particular error message when the value is incorrect
