This is an example of how to use the AppProgressBar class.

#include <app_base.h>
#include <app_progress_bar.h>

void
my_process(AppBase& app)
{
    // create the progress bar
    AppProgressBar *progress_bar = app.create_progress_bar("my process", /*keep_in_history*/ true, /*is_abortable*/ true);

    unsigned int step, step_count;

    // first task: 0% to 20%
    progress_bar->begin_task("first task", 0.2f);
    step_count = 1000;
    progress_bar->set_step_count(step_count);
    for (step = 0; step < step_count; step++) {
        if (progress_bar->must_abort()) break; // abort if needed
        // do stuff
        progress_bar->step(step + 1); // the ith step has been processed
    }
    progress_bar->end_task();

    // second task: 20% to 100%
    progress_bar->begin_task("second task");
    step_count = 4000;
    progress_bar->set_step_count(step_count);
    for (step = 0; step < step_count; step++) {
        if (progress_bar->must_abort()) break; // abort if needed
        // do stuff
        progress_bar->step(step + 1); // the ith step has been processed
    }
    progress_bar->end_task();

    // release the progress bar
    progress_bar->destroy();
}
