ProgressView

ProgressView is a base implementation providing functionality to draw a progress info. Inherits BoxView.

ProgressView draws its content using concepts described below

  • ProgressState contains various info about a runtime state

    • tickStart Lower bound of tick value

    • tickEnd Upper bound of tick value

    • tickValue Current tick value

    • running Running state, either true or false

    • startTime Start time in millis when progress was started

    • updateTime Last known time in millis when progress has updated

  • ProgressContext is a context used with ProgressViewItem

    • description The description given to progress

    • state The ProgressState

    • view The owning ProgressView

    • spinner The Spinner representation used with ProgressView

    • Other methods to help with item drawing

  • ProgressViewItem is a representation of a cell used in ProgressView

There are few build-in items namely text, spinner and percent.

Default ProgressView gives you text, spinner and percent.

ProgressView view = new ProgressView();
view.start();

And looks like:

Customisation

Here’s some examples for various customisations:

ProgressView view = new ProgressView(
	ProgressViewItem.ofText(10, HorizontalAlign.LEFT),
	ProgressViewItem.ofSpinner(3, HorizontalAlign.LEFT),
	ProgressViewItem.ofPercent(0, HorizontalAlign.RIGHT));
view.start();

Align text and spinner to left and give them less space. Align percent to right and give it remaining space.
