      public class Layout
      extends Canvas
      implements HasMembersChangedHandlers

  Arranges a set of "member" Canvases in horizontal or vertical stacks, applying a layout policy to determine member heights and widths.

  A Layout manages a set of "member" Canvases provided as `members`. Layouts can have both "members", whose position and size are managed by the Layout, and normal Canvas children, which manage their own position and size.

  Rather than using the Layout class directly, use the `HLayout`, `VLayout`, `HStack` and `VStack` classes, which are subclasses of Layout preconfigured for horizontal or vertical stacking, with the "fill" (VLayout) or "none" (VStack) `policies` already set.

  Layouts and Stacks may be nested to create arbitrarily complex layouts.

  Since Layouts can be either horizontally or vertically oriented, throughout the documentation of Layout and it's subclasses, the term "length" refers to the axis of stacking, and the term "breadth" refers to the other axis. Hence, "length" means height in the context of a VLayout or VStack, but means width in the context of an HLayout or HStack.

  To show a resizer bar after (to the right or bottom of) a layout member, set `showResizeBar` to true on that member component (not on the HLayout or VLayout). Resizer bars override `membersMargin` spacing.

  Like other Canvas subclasses, Layout and Stack components may have % width and height values. To create a dynamically-resizing layout that occupies the entire page (or entire parent component), set width and height to "100%".

    - #### setCanDropComponents

          public Layout setCanDropComponents(java.lang.Boolean canDropComponents)
                                      throws java.lang.IllegalStateException

      Layouts provide a default implementation of a drag and drop interaction. If you set `canAcceptDrop`:true and `canDropComponents:true` on a Layout, when a droppable Canvas (`canDrop:true` is dragged over the layout, it will show a dropLine (a simple insertion line) at the drop location.

      When the drop occurs, `getDropComponent()` is invoked to determine which component should be added to the layout as a member at the location calculated by `getDropPosition()`. By default this method will return the current drag target. This default behavior allows existing members to be reordered or external components that have `Canvas.canDragReposition` (or `Canvas.canDrag`) and `Canvas.canDrop` set to `true` to be added to the Layout.

      You can control the thickness of the dropLine via `dropLineThickness` and you can customize the style using css styling in the skin file (look for .layoutDropLine in skin_styles.css for your skin).

      If you want to dynamically create a component to be added to the Layout in response to a drop event you can override `getDropComponent()`, or for entirely custom behavior override the `drop event handler` as follows:

             final VLayout vLayout = new VLayout();
             //...various layout properties...
             vLayout.setCanDropComponents(true);
             vLayout.addDropHandler(new DropHandler() {
                 @Override
                 public void onDrop(DropEvent event) {
                     // create the new component
                     Canvas newMember = new Canvas();
                     // add to the layout at the current drop position
                     // (the dropLine will be showing here)
                     vLayout.addMember(newMember, vLayout.getDropPosition());
                     // hide the dropLine that was automatically shown
                     // by builtin SmartGWT methods
                     vLayout.hideDropLine();
                 }
             });

      If you want to completely suppress the builtin drag and drop logic, but still receive drag and drop events for your own custom implementation, set `Canvas.canAcceptDrop` to `true` and `canDropComponents` to `false` on your Layout.

      Note : This is an advanced setting

      Parameters:
        `canDropComponents` - New canDropComponents value. Default value is true
      Returns:
        `Layout` instance, for chaining setter calls
      Throws:
        `java.lang.IllegalStateException` - this property cannot be changed after the component has been created

    - #### setMembers

          public Layout setMembers(Canvas... members)

      An array of canvases that will be contained within this layout. You can set the following properties on these canvases (in addition to the standard component properties):
      - `layoutAlign` -- specifies the member's alignment along the breadth axis; valid values are "top", "center" and "bottom" for a horizontal layout and "left", "center" and "right" for a vertical layout (see `defaultLayoutAlign` for default implementation.)
      - `showResizeBar` -- set to true to show a resize bar (default is false)
      Height and width settings found on members are interpreted by the Layout according to the `layout policy`.

      Note that it is valid to have null slots in the provided `members` Array, and the Layout will ignore those slots. This can be useful to keep code compact, for example, when constructing the `members` Array, you might use an expression that either returns a component or null depending on whether the component should be present. If the expression returns null, the null slot will be ignored by the Layout.
      If this method is called after the component has been drawn/initialized: Display a new set of members in this layout. Equivalent to calling removeMembers() then addMembers(). Note that the new members may include members already present, in which case they will be reordered / integrated with any other new members passed into this method.

      Parameters:
        `members` - New members value. Default value is null
      Returns:
        `Layout` instance, for chaining setter calls

    - #### getMembers

          public Canvas[] getMembers()

      An array of canvases that will be contained within this layout. You can set the following properties on these canvases (in addition to the standard component properties):
      - `layoutAlign` -- specifies the member's alignment along the breadth axis; valid values are "top", "center" and "bottom" for a horizontal layout and "left", "center" and "right" for a vertical layout (see `defaultLayoutAlign` for default implementation.)
      - `showResizeBar` -- set to true to show a resize bar (default is false)
      Height and width settings found on members are interpreted by the Layout according to the `layout policy`.

      Note that it is valid to have null slots in the provided `members` Array, and the Layout will ignore those slots. This can be useful to keep code compact, for example, when constructing the `members` Array, you might use an expression that either returns a component or null depending on whether the component should be present.

    - #### setMinBreadthMember

          public Layout setMinBreadthMember(java.lang.String minBreadthMember)

      Set this property to cause the layout to assign the breadths of other members as if the available breadth is actually wide enough to accommodate the `minBreadthMember` (even though the Layout might not actually be that wide, and may overflow its assigned size along the breadth axis due to the breadth of the `minBreadthMember`.

      Without this property set, members of a layout aren't ever expanded in breadth (by the layout) to fit an overflow of the layout along the breadth axis. Setting this property will make sure all members (other than the one specified) get expanded to fill the full visual breadth of the layout (assuming they are configured to use 100% layout breadth).

      Note : This is an advanced setting

    - #### setOverflow

          public Layout setOverflow(Overflow overflow)

      A Layout may overflow if it has one or more members with a fixed width or height, or that themselves overflow. For details on member sizing see `LayoutPolicy`.

      Note that for overflow: "auto", "scroll", or "visible", members exceeding the Layout's specified breadth but falling short of its overflow breadth will keep the alignment set via `defaultLayoutAlign` or `Canvas.layoutAlign`.

      Overrides:
        `setOverflow` in class `Canvas`
      Parameters:
        `overflow` - New overflow value. Default value is "visible"
      Returns:
        `Layout` instance, for chaining setter calls

    - #### setPaddingAsLayoutMargin

          public Layout setPaddingAsLayoutMargin(java.lang.Boolean paddingAsLayoutMargin)

      If this widget has padding specified (as `this.padding` or in the CSS style applied to this layout), should it show up as space outside the members, similar to layoutMargin?

      If this setting is false, padding will not affect member positioning (as CSS padding normally does not affect absolutely positioned children). Leaving this setting true allows a designer to more effectively control layout purely from CSS.

      Note that `layoutMargin` if specified, takes precedence over this value.

      Note : This is an advanced setting

      Parameters:
        `paddingAsLayoutMargin` - New paddingAsLayoutMargin value. Default value is true
      Returns:

    - #### getResizeBar

          public Splitbar getResizeBar()

      Note : This API is non-functional (always returns null) and exists only to make you aware that this MultiAutoChild exists. See `Using AutoChildren` for details.

      A MultiAutoChild created to resize members of this `Layout`.

      A resize bar will be created for any member of this `Layout` that has `showResizeBar` set to `true`. Resize bars will be instances of the class specified by `resizeBarClass` by default, and will automatically be sized to the member's breadth, and to the thickness specified by `resizeBarSize`.

      To customize the appearance or behavior of resizeBars within some layout a custom resize bar class can be created by subclassing `Splitbar` or `ImgSplitbar` and setting `resizeBarClass` or `resizeBarConstructor` to this custom class. Alternatively, `Canvas.setAutoChildProperties(java.lang.String, com.smartgwt.client.widgets.Canvas)` may be called to set resizeBar properties:

                final Splitbar resizeBarProperties = new Splitbar();
                //...
                layout.setAutoChildProperties("resizeBar", resizeBarProperties);

      See `AutoChildUsage` for more information.

      If you create a custom resize bar class in Java, enable `Reflection` to allow it to be used.

      Alternatively, you can use the SmartClient class system to create a simple SmartClient subclass of either `Splitbar` or `ImgSplitbar` for use with this API - see the `Skinning Guide` for details.

      The built-in `Splitbar` class supports drag resizing of its target member, and clicking on the bar with a mouse to collapse/uncollapse the target member.

      Returns:
        null

    - #### hideMember

          public void hideMember(Canvas member)

      Hide the specified member, firing the specified callback when the hide is complete.

      Members can always be directly hidden via `member.hide()`, but if `animation` is enabled, animation will only occur if hideMember() is called to hide the member.

      Parameters:

      Returns whether there is a pending reflow of the members of the layout.

      Modifying the set of members, resizing members or changing layout settings will cause a recalculation of member sizes to be scheduled. The recalculation is delayed so that it is not performed redundantly if multiple changes are made in a row.

      To force immediate recalculation of new member sizes and resizing of members, call `reflowNow()`.

      Returns:
        whether the layout is currently dirty

    - #### reflow

          public void reflow(java.lang.String reason)

      Layout members according to current settings.

      Members will reflow automatically when the layout is resized, members resize, the list of members changes or members change visibility. It is only necessary to manually call `reflow()` after changing settings on the layout, for example, `layout.reverseOrder`.

      Parameters:
        `reason` - reason reflow() had to be called (appear in logs if enabled)

    - #### reflowNow

          public void reflowNow()

      Layout members according to current settings, immediately.
      Generally, when changes occur that require a layout to reflow (such as members being shown or hidden), the Layout will reflow only after a delay, so that multiple changes cause only one reflow. To remove this delay for cases where it is not helpful, reflowNow() can be called.

    - #### removeMember

        `callback` - action to fire when the member has been shown

    - #### setDefaultProperties

          public static void setDefaultProperties(Layout layoutProperties)

      Class level method to set the default properties of this class. If set, then all existing and subsequently created instances of this class will automatically have default properties corresponding to the properties set on the SmartGWT class instance passed to this function before its underlying SmartClient JS object was created. This is a powerful feature that eliminates the need for users to create a separate hierarchy of subclasses that only alter the default properties of this class. Can also be used for skinning / styling purposes.

      Note: This method is intended for setting default attributes only and will affect all instances of the underlying class (including those automatically generated in JavaScript). This method should not be used to apply standard EventHandlers or override methods for a class - use a custom subclass instead. Calling this method after instances have been created can result in undefined behavior, since it bypasses any setters and a class instance may have already examined a particular property and not be expecting any changes through this route.

      Parameters:
        `layoutProperties` - properties that should be used as new defaults when instances of this class are created
      See Also:
        `SGWTProperties`
