Hi,
I was just wondering if any thought has been put into providing a standard
approach to validating input? Something like ValidatorFX for example [1]? There
have been attempts at solving this in ControlsFX but that one was too heavily
bound to the actual controls while ValidatorFX works on anything that is
observable. I have been using it now for several years in our CRM desktop
application and I feel like it is striking a perfect balance between being
flexible and easy to use.
Small / incomplete example:
TextField userTextField = new TextField();
Validator validator = new Validator();
validator.createCheck()
.dependsOn("username", userTextField.textProperty())
.withMethod(c -> {
String userName = c.get("username");
if (!userName.toLowerCase().equals(userName)) {
c.error("Please use only lowercase letters.");
}
})
.decorates(userTextField)
.immediate();
I know that one can easily say “just use the library” but I think that not
everybody will find it and it also is nice to have a standard way of doing
things.
