timer_id | The timer identifier returned by an earlier calling of callback function FillerAssistCallback::SetTimerCallback. |
|
inlinevirtual |
A callback function used to refresh the specified area on a specified page.
page | A PDFPage object. |
rect | A rectangle that specifies the area on the page to be redrawn. null means to refresh the whole page. |

A callback function used to release current FillerAssistCallback object itself.
|
inlinevirtual |
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.
elapse | Specifies the time-out value, in milliseconds. |
timer | A TimerCallback object as timer. |
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. |
