# FwupdPlugin Progress

#### Description [src]

    final class FwupdPlugin.Progress : GObject.Object
      implements Fwupd.Codec {
      /* No available fields */
    }

Objects can use `fu_progress_set_percentage()` if the absolute percentage is known. Percentages should always go up, not down.

Modules usually set the number of steps that are expected using `fu_progress_set_steps()` and then after each section is completed, the `fu_progress_step_done()` function should be called. This will automatically call `fu_progress_set_percentage()` with the correct values.

`FuProgress` allows sub-modules to be “chained up” to the parent module so that as the sub-module progresses, so does the parent. The child can be reused for each section, and chains can be deep.

To get a child object, you should use `fu_progress_get_child()`. and then use the result in any sub-process. You should ensure that the child is not re-used without calling fu_progress_step_done().

There are a few nice touches in this module, so that if a module only has one progress step, the child progress is used for parent updates.

static void _do_something(FuProgress *self) { // setup correct number of steps fu_progress_set_steps(self, 2);

      // run a sub function
      _do_something_else1(fu_progress_get_child(self));

      // this section done
      fu_progress_step_done(self);

      // run another sub function
      _do_something_else2(fu_progress_get_child(self));

      // this progress done (all complete)
      fu_progress_step_done(self);

}

#### Instance methods

###### fu_progress_add_flag

Adds a flag.

since: 1.7.0

###### fu_progress_add_step

This sets the step weighting, which you will want to do if one action will take a bigger chunk of time than another.

since: 1.8.2

###### fu_progress_finished

Called when the step_now sub-task wants to finish early and still complete.

since: 1.7.0

###### fu_progress_get_child

Monitor a child and proxy back up to the parent with the correct percentage.

since: 1.7.0

###### fu_progress_get_duration

Get the duration of the step.

since: 1.8.2

###### fu_progress_get_id

Return the id of the progress, which is normally set by the caller.

since: 1.7.0

###### fu_progress_get_name

Return the nice name of the progress, which is normally set by the caller.

since: 1.8.2

###### fu_progress_get_percentage

Get the last set progress percentage.

since: 1.7.0

###### fu_progress_get_profile

Returns if the profile is enabled for this progress.

since: 1.8.2

###### fu_progress_get_status

Return the status of the progress, which is normally indirectly by fu_progress_add_step().

since: 1.7.0

###### fu_progress_get_steps

Gets the number of sub-tasks, i.e. how many times the `fu_progress_step_done()` function will be called in the loop.

since: 1.7.0

###### fu_progress_has_flag

Tests for a flag.

since: 1.7.0

###### fu_progress_remove_flag

Removes a flag.

since: 1.7.0

###### fu_progress_reset

Resets the `FuProgress` object to unset.

since: 1.7.0

###### fu_progress_set_id

Sets the id of the progress.

since: 1.7.0

###### fu_progress_set_name

since: 1.7.0

###### fu_progress_set_percentage_full

Sets the progress completion using the raw progress values.

###### fu_progress_set_profile

This enables profiling of FuProgress. This may be useful in development, but be warned; enabling profiling makes `FuProgress` very slow.

since: 1.7.0

###### fu_progress_set_status

Sets the status of the progress.

since: 1.7.0

###### fu_progress_set_steps

Sets the number of sub-tasks, i.e. how many times the `fu_progress_step_done()` function will be called in the loop.

since: 1.7.0

###### fu_progress_sleep

Sleeps, setting the device progress from 0..100% as time continues.

since: 1.7.0

###### fu_progress_step_done

Called when the step_now sub-task has finished.

since: 1.7.0

###### fu_progress_traceback

Create a traceback used for profiling startup.
