Prevent closing a dialog

Posted on by Community Member

Hi all,
i have a dialog which contains some mandatory fields and if these fields are empty the dialog must not be closed.

So i extend the Dialog class and implement some code. Now i want to execute my "mandatory field" logic. But i can't find a way to place my logic (to prevent the dialog being closed...). I tried to overwrite close, but close is never executed???

Any ideas?

Frank

Hi,

thanks for your reply.

I try to explain my steps:

I wrote 2 new classes: The first extends the Dialog class and the second extends the DialogField class.

In the extended DialogField class i added a Mandatory field.

In the extended Dialog class i wrote my own addField method to set the mandatory-Field. In this class i overwrite the close method (to validate the mandotory fields and prevent the form from closing if required) - but the code in close is never executed. And the form is still closed, even if i uncomment the super()....

You have to understand than the Dialog class is not the form itself - it has close() method that calls form's close(), but there is no call in the opposite direction. You would have to modify the Dialog form.

But I wouldn't do that unless really necessary - you can implement a RunBase class, override its validate() method and you have the requested behavior. Or you can at least take a look to the closeOk() method of the Dialog form to see how it's handled for RunBase classes.

Dear Frank,

I think there is problem with your code. I completely agree with the Martin's Reply on this post. Just check your code and try to modifying your code as per Martin's Reply.
