Detailed Description

Classes that handle the Dbo Forms.

This module allows Wt to automatically generate a form for a Dbo class. Based on the data types that are used within the Dbo class, Wt will generate form delegates. These form delegates are responsible for creating the widget, creating an optional validator, and making sure that the data is correctly loaded in and from the model. For example: WString objects are by default represented by a WLineEdit, WDate objects by WDateEdit and so on.

The user is able to override the default behavior one of three ways:

  1. By customizing the widget and/or validator generated by Wt
    See also
    Wt::Form::Dbo::FormView<C>::customizeFormWidget, Wt::Form::Dbo::FormView<C>::customizeValidator
  2. By creating a new form delegate for a specific field and adding it to the view
    See also
    Wt::Form::Dbo::FormView<C>::setFormDelegate
  3. By specializing a form delegate for a specific type (like an enum)
