com.gwtplatform.mvp.client.ViewImpl

All Implemented Interfaces:

IsWidget, View

Direct Known Subclasses:

PopupViewImpl, RootPresenter.RootView, ViewWithUiHandlers

public abstract class ViewImpl
extends Object
implements View

A simple implementation of View that simply disregard every call to setInSlot(Object, IsWidget), addToSlot(Object, IsWidget), and removeFromSlot(Object, IsWidget).

Feel free not to inherit from this if you need another base class (such as Composite), but you will have to define the above methods.

* Important call initWidget(Widget) in your View's constructor.

Method Detail

addToSlot

public void addToSlot(Object slot,
             IsWidget content)

Description copied from interface: View

Requests the view to add content within a specific slot.

Override the default implementation and manage all the slots of your view into which content can be added. You should also consider overriding View.removeFromSlot(Object, IsWidget). If the view doesn't know about this slot, it can silently ignore the request.

Used by PresenterWidget.addToSlot(Object, PresenterWidget).

Specified by:

addToSlot in interface View

Parameters:

slot - An opaque object indicating the slot to add into.

content - The content to add, a IsWidget.

removeFromSlot

public void removeFromSlot(Object slot,
                  IsWidget content)

Description copied from interface: View

Requests the view to remove content from a specific slot.

Override the default implementation and manage all the slots of your view into which content can be added and removed. You should also override View.addToSlot(Object, IsWidget). If the view doesn't know about this slot, it can silently ignore the request.

Used by PresenterWidget.removeFromSlot(Object, PresenterWidget).

Specified by:

removeFromSlot in interface View

Parameters:

slot - An opaque object indicating the slot to remove from.

content - The content to remove, a IsWidget.

setInSlot

public void setInSlot(Object slot,
             IsWidget content)

Description copied from interface: View

Requests the view to set content within a specific slot, clearing anything that was already contained there.

Override the default implementation and manage all the slots of your view into which content can be placed. If the view doesn't know about this slot, it can silently ignore the request. When null is passed, your implementation should clear the slot.

Used by PresenterWidget.setInSlot(Object, PresenterWidget) and PresenterWidget.clearSlot(Object).

Specified by:

setInSlot in interface View

Parameters:

slot - An opaque object indicating the slot to add into.

content - The content to add, a IsWidget. Pass null to clear the slot entirely.
