## Class TMultiView

Description

TMultiView class

TMultiView serves as a container for a group of TView controls. The view collection can be retrieved by Views. Each view contains child controls. TMultiView determines which view and its child controls are visible. At any time, at most one view is visible (called active). To make a view active, set ActiveView or ActiveViewIndex.

TMultiView also responds to specific command events raised from button controls contained in current active view. A command event with name 'NextView' will cause TMultiView to make the next available view active. Other command names recognized by TMultiView include

- PreviousView : switch to previous view
- SwitchViewID : switch to a view by its ID path
- SwitchViewIndex : switch to a view by its index in the Views collection.

TMultiView raises OnActiveViewChanged event when its active view is changed during a postback.

Methods
activateView (line 143)

Activates the specified view.

If there is any view currently active, it will be deactivated.

- access: protected

void activateView (TView $view, [boolean $triggerViewChangedEvent = true])

- TView $view: the view to be activated
- boolean $triggerViewChangedEvent: whether to trigger OnActiveViewChanged event.

addParsedObject (line 56)

Processes an object that is created during parsing template.

This method overrides the parent implementation by adding only TView controls as children.

- access: public
- throws: TConfigurationException if controls other than TView is being added

void addParsedObject (string|TComponent $object)

- string|TComponent $object: text string or component parsed and instantiated in template

Redefinition of:

TControl::addParsedObject()
  Processes an object that is created during parsing template.

bubbleEvent (line 216)

Processes the events bubbled from child controls.

- return: whether this event is handled
- access: public

boolean bubbleEvent (TControl $sender, mixed $param)

- TControl $sender: sender of the event
- mixed $param: event parameter

Redefinition of:

TControl::bubbleEvent()
  This method responds to a bubbled event.

createControlCollection (line 68)

Creates a control collection object that is to be used to hold child controls

- return: control collection
- access: protected

  Creates a control collection object that is to be used to hold child controls

getActiveView (line 111)

- return: the currently active view, null if no active view
- access: public
- throws: TInvalidDataValueException if the current active view index is invalid

TView getActiveView ()
getActiveViewIndex (line 76)

- return: the zero-based index of the current view in the view collection. -1 if no active view. Default is -1.
- access: public

integer getActiveViewIndex ()
getViews (line 172)

- return: the view collection
- access: public

TViewCollection getViews ()
ignoreBubbleEvents (line 182)

Makes the multiview ignore all bubbled events.

This is method is used internally by framework and control developers.

onActiveViewChanged (line 204)

Raises OnActiveViewChanged event.

The event is raised when the currently active view is changed to a new one

- access: public

void onActiveViewChanged (TEventParameter $param)

- TEventParameter $param: event parameter

onInit (line 192)

Initializes the active view if any.

This method overrides the parent implementation.

- access: public

void onInit (TEventParameter $param)

- TEventParameter $param: event parameter

Redefinition of:

TControl::onInit()
  This method is invoked when the control enters 'OnInit' stage.

render (line 264)

Renders the currently active view.

- access: public

void render (THtmlWriter $writer)

setActiveView (line 129)

- access: public
- throws: TInvalidOperationException if the view is not in the view collection

void setActiveView (TView $view)

- TView $view: the view to be activated

setActiveViewIndex (line 88)

- access: public
- throws: TInvalidDataValueException if the view index is invalid

void setActiveViewIndex (integer $value)

- integer $value: the zero-based index of the current view in the view collection. -1 if no active view.
