Members description:

Background As android.graphics.drawable.Drawable
BringToFront
Color As Int [write only]
CurrentPage As Int
Get or Set the current page
DesignerCreateView (base As PanelWrapper, label As LabelWrapper, props As Map)
This method is only for the B4A Designer. Don't call it directly
Enabled As Boolean
GotoPage (Page As Int, Smooth As Boolean)
Jump or Scroll to the new page Page - The new page to display Smooth -
True to smoothly scroll to the new item, false to transition immediately
Height As Int
Gets or sets the view's height
Initialize (EventName As String)
Initializes the object.

pages EventName - Sets the sub that will handle the event.
Initialize2 (Container As AHPageContainer, EventName As String)
Initializes the object.

Layout - A fully initialized AHPagerLayout object with the content of the
pages EventName - Sets the sub that will handle the event.
Invalidate
Invalidate2 (Rect As android.graphics.Rect)
Invalidate a rectangualar part of the object
Invalidate3 (Left As Int, Top As Int, Right As Int, Bottom As Int)
Invalidate part of the object
IsInitialized As Boolean
Left As Int
Gets or sets the view's left position
OffscreenPageLimit As Int
Set the number of pages that should be retained to either side of the
current page in the view hierarchy in an idle state. Pages beyond this
limit will be recreated from the adapter when needed.

This is offered as an optimization. If you know in advance the number
of pages you will need to support or have lazy-loading mechanisms in place
on your pages, tweaking this setting can have benefits in perceived smoothness
of paging animations and interaction. If you have a small number of pages (3-4)
that you can keep active all at once, less time will be spent in layout for newly
created view subtrees as the user pages back and forth.

You should keep this limit low, especially if your pages have complex layouts. This setting defaults to 1.
PageContainer As AHPageContainer [write only]
PageMargin As Int
Set the margin between pages.
PagingEnabled As Boolean
Enables or disables the paging of the ViewPager.
Parent As Object [read only]

Animate the color to a new value
SetLayout (Left As Int, Top As Int, Width As Int, Height As Int)
Changes the View position and size.
SetLayoutAnimated (Duration As Int, Left As Int, Top As Int, Width As Int, Height As Int)
Similar to SetLayout. Animates the change. Note that the animation will only be applied when running on Android 3+ devices.

Duration - duration of the layout change
SetVisibleAnimated (Duration As Int, Visible As Boolean)
Fade the view in or out
Tag As Object
Top As Int
Gets or sets the view's top position
