Qtablewidget input validating

It is generally preferable to provide your own messages, as the default messages by necessity are generic.

The text of the current item is returned by current Text(), and the text of a numbered item is returned with text().

The current item can be set with set Current Index().

The default policy is Insert At Bottom but you can change this using set Insert Policy().

It is possible to constrain the input to an editable combobox using QValidator; see set Validator(). A combobox can be populated using the insert functions, insert Item() and insert Items() for example. An item can be removed with remove Item() and all items can be removed with clear().

This allows you to maintain separation of code and presentation, and keep those messy parameters out of your python code.

Because we strive for loose coupling, you should be able to do that in any templating engine you like, as well.

Or maybe you already use a generic form handling framework but you want to customize the HTML generation of those form fields, and define your own validation.

With WTForms, your form field HTML can be generated for you, but we let you customize it in your templates.

We then check if the request is made using POST, and if it is, we validate the form, and check that the user accepted the rules.

If successful, we create a new User and assign the data from the validated form to it, and save it.

The number of items in the combobox is returned by count(); the maximum number of items can be set with set Max Count(). For editable comboboxes you can set auto-completion using set Completer() and whether or not the user can add duplicates is set with set Duplicates Enabled().
