Detailed Description

xfa/fwl is a Widget Library for XFA Forms.

CFWL_Widget is the base class that widget classes extend. The derived widget classes are both controllers and renderers for each widget. The hierarchy is:

• CFWL_Widget
  • CFWL_Form
  • CFWL_Caret
  • CFWL_CheckBox
  • CFWL_ComboBox
  • CFWL_DateTimePicker
  • CFWL_Edit
    • CFWL_Barcode
    • CFWL_ComboEdit
    • CFWL_DateTimeEdit
  • CFWL_ListBox
    • CFWL_ComboList
  • CFWL_MonthCalendar
  • CFWL_PictureBox
  • CFWL_PushButton
  • CFWL_ScrollBar
  • CFWL_SpinButton

These CFWL widgets are instantiated by and closely related to the CXFA classes in the xfa/fxfa directory. See xfa/fxfa/README.md.

CFWL_Widget implements IFWL_WidgetDelegate through which it receives messages, events and draw calls.

Messages consist of user input for a widget to handle. Each type of message is identified by an enum value in Message::Type and has its own class derived from the base CFWL_Message.

• CFWL_Message
  • CFWL_MessageKey
  • CFWL_MessageKillFocus
  • CFWL_MessageMouse
  • CFWL_MessageMouseWheel
  • CFWL_MessageSetFocus

Events are originated in the widgets and are then handled by other CFWL_Widget and CXFA classes.

• CFWL_Event
  • CFWL_EventCheckWord
  • CFWL_EventMouse
  • CFWL_EventScroll
  • CFWL_EventSelectChanged
  • CFWL_EventTextWillChange
  • CFWL_EventValidate

The widgets use IFWL_ThemeProvider for rendering everything, calling DrawBackground() and DrawText() and passing many options in their parameters, respectively of types CFWL_ThemeBackground and CFWL_ThemeText. See xfa/fwl/theme/README.md.
