Syntax
public class ProgressBar : View, IEnumerable
Remarks

ProgressBar can operate in two modes, percentage mode, or activity mode. The progress bar starts in percentage mode and setting the Fraction property will reflect on the UI the progress made so far. Activity mode is used when the application has no way of knowing how much time is left, and is started when the Pulse() method is called. Call Pulse() repeatedly as progress is made.

Constructors

ProgressBar()

Initializes a new instance of the ProgressBar class, starts in percentage mode and uses relative layout.
Declaration
public ProgressBar()

ProgressBar(Rect)

Initializes a new instance of the ProgressBar class, starts in percentage mode with an absolute position and size.
Declaration
public ProgressBar(Rect rect)
Parameters

Properties

Fraction

Gets or sets the ProgressBar fraction to display, must be a value between 0 and 1.

System.Single The fraction representing the progress.

Methods

Pulse()

Notifies the ProgressBar that some progress has taken place.
Declaration

Remarks
If the ProgressBar is is percentage mode, it switches to activity mode. If is in activity mode, the marker is moved.

Redraw(Rect)

Redraws this view and its subviews; only redraws the views that have been flagged for a re-display.
Declaration

Parameters
Type Name Description
Rect region
Overrides
Remarks

Always use Bounds (view-relative) when calling Redraw(Rect), NOT Frame (superview-relative).

Views should set the color that they want to use on entry, as otherwise this will inherit the last color that was set globaly on the driver.

Overrides of Redraw(Rect) must ensure they do not set Driver.Clip to a clip region larger than the region parameter.
