This class represents a callback object to assist form filler. All the pure virtual functions in this class are used as callback functions and should be implemented by user.

pure virtual |
A callback function which is triggered when the focus is set to a form control.
This callback function supports text field, combo box field, list box field, push button field, check box field, radio button field.
[in] | control | The form control object to which the focus is set. |
[in] | value | The value of form field associated with the control. If the control belongs to a push button field, this value would always be an empty string. |
|
pure virtual |
A callback function which is triggered when the focus is lost from a form control.
This callback function supports text field, combo box field, list box field, push button field, check box field, radio button field.
[in] | control | The form control object, from which the focus is lost. |
[in] | value | The value of form field associated with the control. If the control belongs to a push button field, this value would always be an empty string. |
|
inlinevirtual |
Get the version of derived implementation, for compatibility reason.
|
pure virtual |
A callback function used to kill the timer event by timer identifier.
[in] | timer_id | The timer identifier returned by an earlier calling of callback function FillerAssistCallback::SetTimerCallback. |
|
pure virtual |
A callback function used to refresh the specified area on a specified page.
[in] | page | A PDFPage object. |
[in] | rect | A rectangle that specifies the area on the page to be redrawn. NULL means to refresh the whole page. |
|
pure virtual |
A callback function used to release current FillerAssistCallback object itself.
|
pure virtual |
A callback function used to set a system timer.
This callback function is called to install a system timer. When a time-out value is specified, and every time when a time-out occurs, the system passes a message to the timer callback function.
[in] | elapse | Specifies the time-out value, in milliseconds. |
[in] | timer | A TimerCallback object as timer. |
[out] | out_timer_id | Output parameter that receives the timer identifier of the new timer if the function is finished successfully. This value would be passed to callback function FillerAssistCallback::KillTimer to kill the timer. Nonzero if the function is successful; otherwise, this should be zero. |
