### add

    public void add(Widget w)

  Deprecated.
  Description copied from class: `Panel`
  Adds a child widget.

  How to Override this Method

  There are several important things that must take place in the correct order to properly add or insert a Widget to a Panel. Not all of these steps will be relevant to every Panel, but all of the steps must be considered.

  1. Validate: Perform any sanity checks to ensure the Panel can accept a new Widget. Examples: checking for a valid index on insertion; checking that the Panel is not full if there is a max capacity.
  2. Adjust for Reinsertion: Some Panels need to handle the case where the Widget is already a child of this Panel. Example: when performing a reinsert, the index might need to be adjusted to account for the Widget's removal. See `ComplexPanel.adjustIndex(Widget, int)`.
  3. Detach Child: Remove the Widget from its existing parent, if any. Most Panels will simply call `Widget.removeFromParent()` on the Widget.
  4. Logical Attach: Any state variables of the Panel should be updated to reflect the addition of the new Widget. Example: the Widget is added to the Panel's `WidgetCollection` at the appropriate index.
  5. Physical Attach: The Widget's Element must be physically attached to the Panel's Element, either directly or indirectly.
  6. Adopt: Call `Panel.adopt(Widget)` to finalize the add as the very last step.

  Specified by:
    `add` in interface `HasWidgets`
  Overrides:
    `add` in class `Panel`
  Parameters:
    `w` - the widget to be added
  See Also:
    `HasWidgets.add(Widget)`

### isResizing

    public boolean isResizing()

  Deprecated.
  Indicates whether the split panel is being resized.

  Returns:
    `true` if the user is dragging the splitter, `false` otherwise

### iterator

    public java.util.Iterator<Widget> iterator()

  Deprecated.
  Description copied from interface: `HasWidgets`
  Gets an iterator for the contained widgets. This iterator is required to implement `Iterator.remove()`.

### onBrowserEvent

    public void onBrowserEvent(Event event)

  Deprecated.
  Description copied from interface: `EventListener`
  Fired whenever a browser event is received.

  Specified by:
    `onBrowserEvent` in interface `EventListener`
  Overrides:
    `onBrowserEvent` in class `Widget`
  Parameters:
    `event` - the event received

### remove

    public boolean remove(Widget widget)

  Deprecated.
  Description copied from class: `Panel`
  Removes a child widget.

  How to Override this Method

  There are several important things that must take place in the correct order to properly remove a Widget from a Panel. Not all of these steps will be relevant to every Panel, but all of the steps must be considered.

  1. Validate: Make sure this Panel is actually the parent of the child Widget; return `false` if it is not.
  2. Orphan: Call `Panel.orphan(Widget)` first while the child Widget is still attached.
  3. Physical Detach: Adjust the DOM to account for the removal of the child Widget. The Widget's Element must be physically removed from the DOM.
  4. Logical Detach: Update the Panel's state variables to reflect the removal of the child Widget. Example: the Widget is removed from the Panel's `WidgetCollection`.

  Specified by:
    `remove` in interface `HasWidgets`
  Specified by:
    `remove` in class `Panel`
  Parameters:
    `widget` - the widget to be removed
  Returns:
    `true` if the child was present

### setSplitPosition
