Validation of text inputs and showing an error message

[ThorQue]

Hello,

in the SDK docs of the LrView there is this function mentioned:

validate : (Read-Only)A function called to validate the value. (function, default: nil) The function takes this form:

myValidate( view, value )

Parameters:

1. view (LrView) This control.
2. value (any) The value to validate.

Returns three values:

1. result (Boolean) True if value was valid.
2. value (any) The new value.
3. message (string) If result is false, an error message.

First supported in version 1.3 of the Lightroom SDK.

This works fine, but I am wondering where the error message can be shown? I have no glue what I need to do to show the message to the user.

Thanks in advance

Thorsten

Already resoved by me 🙂 If I lost the focus of the input field I get a message box with the error message.
