Detailed Description

Progress callback from another progress This class allows you to pass a progress callback to a subtask based on a current progress data, plus a weight value. Every progress reported by the subtask via this callback will be forwarded to the main progress data, with the corresponding weight.

Example:

 // receiver for main task
 void task_receiver( ProgressData &progress );

 // subtask prototypes
 void do_subtask_one( ProgressData::ReceiverFnc &fnc );
 void do_subtask_two( ProgressData::ReceiverFnc &fnc );

 // main task
 ProgressData progress;
 //progress for subtask 1
 // which is 80%
 CombinedProgressData sub1(pd, 80);
 // the second is only 20%
 CombinedProgressData sub2(pd, 20);
 do_subtask_one( sub1 );
 do_subtask_two( sub2 );
