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 );
