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.
